Tank Suspension Systems - Pros And Cons
Vložit
- čas přidán 27. 07. 2024
- Tank Suspension has come a long way from the days of solid steel tracks rolling on the frame of the Mark I tank of the First World War. But today the main battle tank is utilizing a whole host of new and old suspension systems and shock absorbing systems to help keep these heavy and impressive tanks rolling across rough terrain.
No tank is invincible though and even some of the most technologically advanced suspension systems can fail. In this video we discuss SOME pros and cons of the Hydro pneumatic suspension, in particular the Hyrdogas Suspension system of the Challenger 2, and also torsional bar suspension. Both have very good features, but they both have their weaknesses.
What do you think about tank suspension? Is it time for newer systems or do you feel we are doing well with what we have?
Stay until the end of the video and find the small challenge I have set for you guys......... ;-)
Hope you enjoy!

Hydro-pneumatic Tank Suspension Systems - Pros And Cons - Auta a dopravní prostředky
tank suspension is so satisfying to watch when it rolls over rough terrain

"wow that tank's gun is tracking me beautifully what a marvelous piece of engin..."

Two additional important disadvantages of torsion bars are that they run transeversely accross the floor of the vehicle and the overall height of the vehicle is significantly increased. This was one of the reasons the Brits kept the Christie type suspension for the Comet tank rather than use torsion bars. The other disadvantage is that, although as discussed, torsion bars are relatively easy to replace on an undamaged tank, if you have lost a suspension unit due to a mine or a projectile strike and the hull is damaged, it becomes a major job involving cutting and welding the hull to remove the damaged bar and, if at all possible, to replace it. One important suspension system not discussed here is the helical spring units used by the Centurion and the Chieftain and still being used by the Merkava. These units have the easy replaceability of the hydrogas units but they are cheaper, more reliable and easier to maintain than the hydrogas units, and they do not increase the height of the vehice. They generally have poorer flotation characteristics than either hydrogas syspens or torsion bars however, i.e. the ride quality will suffer, especially at high speed. I believe it is significant that the Brits decided to move away from these units and replace them with hydrogas on the Challenger and the South Africans replaced the coil spring units with torsion bars on the final iteration of the Olifant tank, a modified Centurion.
German torsion bars intensify
TheGamingSoviet German torsion bars took it to a new level. Even by today's starndards that shit was advanced

Rip streets
Haha! thanks for watching
The Abrams uses the bar system. I will agree that it isn't as comfortable a ride as a pneumatic system ( being a gunner on it I get slammed into the sights by new drivers) but the maintenance is very very little.
What tank with hydro-pneumatic did you drive?
can you do a video about gun stabilization?
yes do pl0x
That would be interesting. Just don't ask him to do one on tank/IFV transmissions. The video would be 3 hours long and require a Masters Degree in mechanical engineering to follow it.
Karl P I know how they work lol
Matsimus Gaming do Russian tanks have gun stabilizers?
+Matsimus Gaming do you know how a CVT transmission works in the Type 10 MBT for example? that was something that seemed really cool to me going full speed in reverse, Leclerc needs this.
+Vlad Dracula yes Russian tanks have stabilizers even since the IS series of tanks they've incorporated vertical stabilizers on the IS-8/T-10 and that's so much as when 'heavy tanks' were still a thing lol. On their modern tanks though, hell yeah all the more, just search 't-90 tank shot' or search for the T-90 shooting in the air, it can do this and hit a target if the gunner is competent enough.. Like, even the base model T-72 had 2-plane stabilization, not super advanced or anything but it was enough to shoot on the move given that the ground didn't cause the tank to change it's velocity THAT drastically to the point that the stabilizer couldn't keep up.. The thing about stabilization is that, it can get so good until a point, but without the innovations of ammunition to give us longer engagement ranges and precision at those ranges well our stabilizers are just there to allow us to achieve those 'hard-coded maximums' if you will, which Russian stabilizer technology is by all means up to par with. The biggest difference in 'technology' when it comes to Russian and NATO tanks is sensors, such as thermal imaging, and this comes inherently with the fact that those sensors are MASSIVELY expensive and there's plenty of reasons why the US has the highest military budget by FAR of any military on the planet.

I had no idea hydro gas type of suspension even was a thing. Pretty cool.
heavylifter315 haha yeah it's a sweet system. Thanks so much for watching :-)
you have it on your car ;)
@@justarandomguy3969not necessarily.
@@johnnunn8688 he would have to have a car from pre 1990 to have pure hydraulic fluid, very few if any comes with it after 1990
If you can guess which Hyrdogas is failing/failed then let me know which tank, what time it shown and what station it is and what side :-D
HAPPY HUNTING! The first person to find it will be getting sent a small gift! :-D
Matsimus Gaming 16:05 mid I think
@Matsimus Gaming 6:24 the tank in front, the 1st station on the right side?
14:36, the unit 1 on the right side has failed the roadwheel does not put tension on the track wich cause the roadwheel to try to derail.
darklabor looks like we have a winner :-) well done my friend. Please email me when you have a chance for your prize! :-) matsimus9033@gmail.com
Matsimus Gaming OH MY GOSH ITS SO OBVIOUS! I didn't look at any footage after the challenge was made in the video. A mong am I...
Thank you. This is the closest I was able to come to a video explaining how tank treads work.
Great video Mats! Nice to hear what the maintenance crew had to say about the suspensions.
So a few general things to know:
Torsion bar:
It's the gold standard of suspensions nowadays.
Compared to the Christie suspension it took less internal space, gave better ride quality and was lighter. It is also in general the lightest of the older types of suspensions. But some drawback are that it takes up internal volume and makes the vehicle taller, as well as the torsion bars being a hazard to crew during a blast mine explosion under the tank. And simply the fact that a shattered rod takes a lot of work to clear out and fix.
Used in the Merkava is a sort of coil spring suspension. It is extremely rugged (used the the rocky Golan heights) and reliable. The suspension is also said to provide better ride quality then torsion bar, but that is not confirmed. It is also well protected and easy to replace, just remove the module and attach a new one. Also takes up no internal volume. The downsides to the system is the increased weight.
Hydropeumatic suspensions or hydrogas are a newer type. They are generally lighter. (Makes up 7-8% of the vehicles total weight, compared to the torsion bars 10%). As well as beings easily replaceable. Well, "easily". They also give you a better ride quality compared to torsion bar, meaning they need less wheel travel (475mm for CR2, 520mm for Leo 2 and M1 and 600mm for Merkava). They can also go into a semi-active or active more, were the suspension adapts to the terrain automatically and the tank can be raised and lowered, changing the ground clearance, as well as kneel to increase gun depression.
Another newer prototype suspension is the electromagnetic suspension. Using magnetism to dampen the impact. These are very equal to the hydropeumatic suspensions in performance, all though ride quality should be very slightly worse because of more unnsprung mass. The upsides however, is the easy of maintenance, simply remove the module, with no need for a gas bottle or pump. And they are also said the be 25% more efficient than hydropeumatic suspension when they enter active mode. (The system needs power to vary the stiffness of the individual suspension units.)
Another intriguing suspension technology is the adaptive suspension, which uses cameras to adapt the suspension to incoming terrain, and has shown to increase the top speed of tanks. Just search BAE F1 suspension in tanks.
Cheers
Xoon.
15:31 Wait, here comes the crescendo!
cccooooooolllllllll hahahaha! Gotta love some classical sometimes :-)
worth mentioning the K2 Black Panther ISU system as a next step in suspension evolution...
i love the merkava suspention system, tank jumped off a 3-4 meter cliff and it saved my ass! in all the years iv had experience with it never had any problems with it! would be nice to ride in a tank with an Hyrdrogas Suspension system to see how they compare.
if you haven't already you should do a video on the Japanese type 74 and its weird suspension.
Great video mate, hope you consider doing more of these engineering type vid's, very interesting for some of us afv modellers also.
6:05, the fifth road wheel on the right track (crew perspective) seems to have Oil on it. Either that or it's wobbling around. Both sign for a broken suspension.
Meridian nope not that one :-) try again and thanks for watching
Great video, increased my respect for mechanics and engineers out there. Just thinking about how many things needed to understand just to be able t keep the vehicle functional makes my hea hurt.
Hello. The suspension system has been the biggest mystery of tanks to me. Thank you.
The ability to raise and lower ride height, tilt the vehicle laterally and longitudinally gives advantage for hydrogas. Also the torsion bar suspension raises vehicle height because they run right across the vehicle width creating a double floor effect between the belly plate and the inner hull floor (you don't want to be standing on torsion bars right?).
But say on the Leopard the main thing that gives it leading mobility are the excellent (Koni) hydraulic dampers as well as the torsion bars. Two systems. Also the tracks (Diehl) are considered to be excellent as well, so need to look at the whole package, when talking about mobility in general.
Very cool vid. I made my ptv with air shocks from a minivan, LOL. I went with air shocks because of the adjustable air pressure. Never thought about the ride quality which was like floating on air. A big bonus is, I have adjustable ride heights. I can fully extend the suspension for 12 inch ground clearance for off road, or slam it on the ground with 3 inch ground clearance for a low rider, LOL, by adjusting the limit straps. I also have double wheel bogies which helps with ride quality too.
The hydro pneumatic systems can incorporate both spring and dampening functions within an integrated unit whereas a torsion bar is spring only. In this case seperate damper tubes are fitted to the suspension arms of some of the road wheels, typically the first, second and last. This reduces the stresses on the torsion bars and on the tracks if the torsion bar is returning from its "compressed" state whilst the road wheel is unloaded i.e. snapping back and over-tensioning the tracks. The addition of damper tubes also helps reduce vibration and create a smoother ride thus enhancing crew endurance.
Torsion bars extending the full width of the hull also necessitates asymmetry in the arrangement of road wheels. In the M113 class of vehicles this results in the left track having one less link than the right track (and hence the oft-heard joke that the driver, situated over the left track, is the "missing link"). This leads to the vehicle always pulling slightly left on smooth surfaces and bigger issues of the asymmetric stress on either side of the drive system. That leads to bigger costs as components and maintenance systems have to be tailored for each side of the vehicle.
The future: The obvious next-step is an active system that reads the terrain and moves each individual suspension arm such that its road wheel is in the exact correct position to support the vehicle and transmit the minimum dynamic load to the hull when the individual road wheel has arrived over that piece of terrain. That would require a lot of complex computing and that requires a lot of power. Actively moving a dozen suspension arms up and down needs more power. An active system means you're creating some sort of signature that can be exploited, so the requisite countermeasure will use more power. And on it goes................

Sunray11, Out.
So satisfying in addicting to watching those tracks
I served on the M60A3 which had a less advanced suspension and even if we were cursing the driver and getting slammed from side to side int he turret - the gun always remained dead on target.
And in an entire career on tanks - I never adjusted the torsion bars. And never had one break. I did have several replaced during quarterly maintenance (where things that are difficult to check and rarely fail get inspected and these inspections are done by the mechanics with the tanks crews assisting*).
* I was rather possessive of my tanks and didn't want anybody touching them without a member of my crew watching. My attitude was that the only people I could count on to take proper care of it was me and my crew.
Great video as usual. Love your content, keep it up!
Will de Kretser thanks so much I really appreciate that! Have a great day
Hello Matsimus! I think that road wheel that failed is at 8:50 - 8:56, left side, wheel number 6 (nearest to the sprocket). My reasoning is:
1. Wheel do not extend as much as other wheels;
2. Turret is turned at 6 o'clock in order to provide proper weight distribution for condition;
3. Tank is parking for repair (maybe);
4. Bonus reason - Commander looks pissed off and driver is kind of bummed.
Also: Very nice channel, hope to here from you and I like for you to do special video about merkava tenk suspension.
Good vid. Glad the music was nice and quiet! Little footnote, two classic English cars had a torsion bars (on the front only) . Morris Minor and E-Type Jaguar (XKE)!
Matsimus, i love tank mechanics, is wham makes me amazed about them, please, make more videos like this, i'll watch them all!
I look back on my 10 year career in the Chertsey workshops during the development of Chall1 and the amusement when having a thrash around Long Valley and wondering why the vehicle was drooping a bit on one side. Only to find we had lost a complete hydrogas unit wheels and all. Main problem was you couldn't tell with all the slewing and grinding cross country that it had happened. It certainly transformed the ride from the Chieftain and along with the appalling build standard of the gearbox and the main brakes there was plenty to keep us in overtime. I never really understood why an onboard system allowing the hydrogas units to be adjusted by the crew even while on the move would have given the capability to squat down when hiding to lower the profile and jack back up for cross country. An engineer working with the units said you could loose one of the middle stations but a front or rear was a stopper. Next call to REME to bring a unit and crane. Those suckers were heavy.
i think that japanese (and french) hydro-gas suspension are the most refined ones ! they are more "tunable" to terrain and gives smoothness needed to "hit on the move" but they requires a bit more maintenance
Torsion bars are more rugged, less comfy but deal better with rough terrains and are better in off-road situation
As always, it's a strategic choice, you must choose the ones which fits your tactics the best
Doctrine again ! It's always doctrine of use of the army !
Rugged vs Refined
OR : torsion bars on light tanks ! CVR-T were amazing on rough terrains like the T-90 (which is pretty light for a MBT)
AND : hydro-gas on heavy tanks
all fine and complex systems requires good trained crews, hydro-gas are expensive and requires maintenance, if your army can't train crew well, go for torsion bars...
Dude , don't forget T-80 it work with torsion bar splendidly .
it's quite light compared to M1 !
Russians have really good gyro-stabs, they don't need good suspensions ! ^^
Well, the french ones are quite rugged, they endure all shocks to the point that it is the hull that suffers from the more catastrophic shocks. During the tank competition in Sweden, the testing crew throw the tank and damaged the hull, the suspension units where fine but the mounting points on the hull where widened. This caused some controversies because, the militaries of the STAT (french army technical section) never reached that degree of pressure even when they sent the tank in trenches with 1-2m jumps at the end of the manoeuver. Recently the UAE tanks that were damaged by AT land mines also have the hull damaged (bearing plate bent, suspension units scratched at worst, and track thrown).
A con of the torsion bar system is that, when it fails there are high chances that you have a domino effect with the redistribution of the weight...
Hydro gas suspension has damping built in, torsion bars require external dampers. For a tank it’s usually just a friction snubbed though.
The merkava actually uses coil springs, and supposedly actually has the most wheel travel. I think it’s actually similar to a modernized version of the Churchill’s suspension.
I think there’s also a system I think called “in arm” that according to horstman’s website (which exists?) is a further development of hydro gas. I think there might have been a different in arm suspension developed as a prototype in the US? The US has this giant kinda poorly documented history of experimental tank designs that never went anywhere.
love how you put in the Mark 1 or 3 tank
My 2002 Chevy Suburban has torsion suspension in the front. When I first bought it fourteen years ago, I was a bit leery of that design choice, especially considering it is fitted with a snow plow. I changed my opinion over time. It rides great whether it's on the highway or a logging trail. It has been problem free all these years, even with the added load and stresses of the plow.
Finally. With Sprocket out, I've been wondering what makes one suspensions system work where another one doesn't.
Thank you, great video!
thanks for the WW1 tank video. I didn't even know one was running.

Matsimus Gaming so hey Mat I'm designing an electromagnetic suspension unit for my Collage midterm and I'm wondering what the average weight of an M1A2 and of the leopard 2 is, you see I want to go into tank design and I believe this project might be a good way to get the attention of an agency like DARPA, I'm also wondering if you would mind it too terribly if I asked you to review the diagrams of my project after all your knowledge and experience with heavy armoured vehicles could prove both crucial and infinitly valuable since I don't have access to an actual M1A2 nor do I have the capacity to build a full-size/ full-scale prototype.
I would rather appreciate a response.
I should also warn you that if you do accept to check my diagrams you will find them incomplete this is because the suspension system is only one part of a full modernization package for the M1A2 and the leopard (Sadly the structure of the challenger is incompatible with the package) I am currently working on, for obvious reasons aside from the suspension system I must keep the rest of the details secret (After all if I do catch the attention of a potential employer I must have something to show for my self and it would be bad if the details of my potential product were leaked to less than reputable company)
Sadly I dont know enough about the M1A2 anyway. Sorry. There are a lot of sources for your info that you can find via google. Tanks for watching
You know you can likely look it up right?
+Anarchy Empire M1A2 weighs 65 tons
Leopard 2A6 weighs 62 tons
Is electromagnetic suspension really practical? Sure it sounds cool..
IndustrialDonut not by it's self but it's part of a full conversion package which should in theory allow something like an M1A2 (or A4 if this upgrade works out) to be able to run at a speed of 125MPH in roads, 110 of road, and be able to make an almost instant stop... and if your weight is correct I should be able to bring down it's weight by almost 15 tons while also increasing its survivability by almost 95%, you see both this tanks are almost 50 years old they are ancient in Technological terms what I aim to do is simply bring them forth into the modern age.
Very informative video, I never knew how each system worked! What was that program that you were using to show the different suspension's in simulated terrain?
Yes, if it's not Steel Beasts, I want to know too!
sorry to burst the bubble but I never heard so much bullshit in a video about tank suspension ever. I gunned tanks and IAFV's for 10 years.
I LIKE THE V FOR VENDETTA BACKGROUND ANTHEM :D
AND THANKS FOR THIS VERY INFORMATIONAL VIDEO BRO. S FOR SUSPENSIONS !
those are some damn good animations right there~
+Matsimus Gaming Great vid, it does clear up a few things, ..at least the UK hydrogas is seemingly better than the Chiefy's springs for repairing and the likely safety/sanity measures too in dealing with those multiple springs?
..For all those saying after watching the video X amount of times and saying this or that wheel(s) on the C2 around the 15 minute+ mark, having a wonky wheel or defective suspension, I think Matsimus Gaming did say
"..different wheel stations (along the length of the tank; I add) are tuned for different resonances (compression & bouncing/rebound frequencies; I add).."
- this is too try and stop harmonic resonance transmitting to the hull and making the crew feel vomity, and when slowing or stopping, enable faster 'settling' reduce rocking.
Some of the 'strange angle of the 5th wheel is wheel dirt, + airborne dust/dirt + also down to camera/film quality and resolution, and parallax error from the curvature of the camera lens - as the camera is more centred upon the central front stations.
And sorry for those, the UK Hydrogas types are not the same as the Japanese (and possibly the French one(s) too - AFAIK, UK ones is just for the aerogas springing, and not for on the fly adjustment too for height and cant.
But as Matsimus Gaming would most likely add, I am likely wrong on even more finer points yet alluded too.
Nice job as usual!
Seth Logan thanks so much! Have any guesses on the one that is broken in the video!? :-)
Matsimus Gaming no idea :)
we used the same two types under heavy, high end boat trailers. of course the hydrogas setup was all pre set and sealed for gvw
Thx mat! I am starting an engineering project thing soon and this has given me a great idea on what the subject should be :D
Bailey Smith awesome! Glad it helped you! Thanks so much for watching and please share the video around :-)
I'm a qualified mechanical engineer, I'd give you a hand if you like.
12:15 In up-armored Pattons, Torsion bars are not very reliable, and break quite often. Replacing them is a pain in the ass
And there's a third Suspension type you did not mention - the coil spring suspension , as used in the Merkava tanks, which gives them cross-country performance on rocky terrains on the expense of weight and bulkiness
Almost every main battle tank in the world uses torsion bars- Brits are using hydro pneumatic suspension
Almost every main battle tank in the world uses smooth barrel- Brits are using rifled barrel for the main gun
Almost in every country cars are driving on the right side of the road- Brits are driving on the left side
Truly stubborn people LOL
Гаврило Принцип aye that we are.
Hydrogas is actually preferable for tracked AFVs.
Rifled guns are still trash though.
They still use HESH ammo as well
@@olegc.7877 The British are completely 'stuck' on their Island, Matsimus is a perfect display of that. I never heard so much bs about torsion bar suspension in my life.
Hydrogas certainly gives superior off road ability. As to the correct size of the road to drive on, it's the rightsiders who are being unreasonable. The reason we have islands on the starboard side - right - of aircraft carriers is that it was early discovered that pilots in trouble tend to veer left. The same applies to drivers which is not a great problem if you are driving on the left-hand as you tend to end up on the verge. If you are stupid enough to be driving on the right, you end up facing oncoming traffic and immanent death.
This video had me in suspense
Luke Williams EYYYYYYYYYYYYYYY!!
Very interesting, one of the underpraised aspects of a tank or any AFV. People always wanna know about guns, armour and crew. Without suspension as good as they are, tanks would have a hard time not killing their own crews!
Harrison Rawlinson very true :-) as mechanical trades person on these vehicles sometimes it's nice to show the mechanical side of it. Thanks so much for watching!!
Can you discuss some of the older suspension types such as leaf springs.. If you did not do so already?! Keep up the good work!
God, where did you get those animations from, they are BEAUTIFUL!
A torsion bar and a coil spring work the same. Both twist when a load is placed on them. A coil spring is essentially a torsion bar wrapped around a cylinder, and a torsion bar is pretty much an unwound coil spring. It took a while for some track mechanics to wrap their minds around that one in training.
Very good! Could you make videos about light armoured army vehicles, like Panhard Vbl? It's one of my favourite army vehicles and very popular to many armies in the world.
And now a good comparison of live track vs dead track.
I'm going to guess 8:04, he has his hazard lights on! looks like the rear right road wheel isn't doing the pushing for the coushion.
Great video man. What is your opinion on the Merkava's helical spring suspension?
sakpan74gr thanks so much! Glad you liked it. To be fair I'm not sure I have never looked into it. Do you have a guess as to what suspension has failed in the video? :-)
Talking about tanks and listening Tchaikovsky's "Swan lake'? YES! :)
Great video as always!
Thanks josh! Glad you liked it! Tanks for watching! ;-D
Matsimus Gaming
:)
We enjoy your videos so "Tanks to you"
Theonelordnikon haha you guys are awesome!
What program did you use in the 3D examples when you were explaining how the suspension works? Thanks!
I remember this suspension from my first car, an Austin Allegro 1750, it was great at soaking up bumps - highway handling, not so much...
Lucid Nonsense haha fair one. Thanks for sharing and have a great day!
do one about the HVSS on the m4a3.
why do they not change all and the rear mechanics charge the hydrogas suspension? Tension bars from experience they could very difficult to take out, because of the angle, that you need to take them out, and sometimes snaps also when the tank is parked, and not moving.
Where did all the suspension animations come from? Those were really cool
How about In arm suspension's Pros And Cons ?? Used to K2
another downside of torsion bar is torsion bar rock. experienced it on cvr(t) a few times. the best thing about hydrogas is the hotter the units get, the higher the ride hight becomes and the better the ride. driving both afvs is nice, but you can't beat rocking around in an MBT. MENTE ET MANU.
kippamip very good points! Thanks so much for watching :-)
Keep this great work up. I really love your vids, especally your tank reviews.
Could you maybe do one of the older cold war tanks like the chieftain or the conqueror. Could you maybe also talk once about your time in the british army and in afghanistan.
MM S thanks so much! Really glad you like my content! Please feel free to share the video around! :-) I will be doing a lot more tank videos. Once the modern ones are done I will move onto older :)
At about 14:30 first road weel on front left as you are facing the front of the tank. The first road wheel jumps as he is making a right hand turn.
What program did you use to animate the tanks? Tank suspension at work is mesmerizing for me
Great video could you do a follow up talking about bogey and Christie suspension.
Orange_Phoenix meh... I don't do much on older stuff but I'll have a think about it :-) thanks for watching
You are making your preference very clear by showing Panther tanks when talking about torsion bars when it just as well could have been a Leopard 2A7 or a M1A2 Abrams....
6:10 of the video. Second tank pulling up has a pronounced list to it's right side. Plus it's making more noise than the first tank. So I'm guessing the roadwheel closest to the front (right side) is the culprit.
There's also the still picture of the tank with the 2 gas chargers servicing the left side. But that could just be routine maintenance.
Cheers
Craig
ceedub04 sorry Craig not the right one. But great guess! Someone guessed correctly today :-) thanks so much for watching
Where did the computer simulations of the Challenger, King Tiger, and Jagdpanther come from? Nice video
what about the coilspring/helical spring used on the merkava?
Might just be the surface that makes it look like it but the Challenger on the right at 6:50
Its 5th station on the right side (obviously as its the only one we can see at that point) looks to be offplace somehow and it also looked as if it was wobbling when he went down the road in a way it shouldnt.
Btw great video man :D
Piskfinne not the right one but good guess! Thanks so much for watching :-)
Hello.
I just found out your channel. Interesting stuff.
I am just curious if you'll ever tell us which suspension unit failed :-)
My guess: 6:00, first road wheel on the right side.
All the best!
If you look at the tank at 6:05, the fifth road wheel from the front on the right track (crew perspective) seems to have issues while moving. It looks like it's wobbling around. Might also be a Oil patch from a broken suspension that makes it look like it's wobbling.
Meridian nope it's not that one :-) someone guess correctly today! Thanks so much for watching
Matsimus Gaming Thanks so much for making those awesome videos :)
Can I ask what are the 2 tanks in the back of the Challenger? Are they fuel tanks and can explode?
An advantage of hydropneumatic over torsion bar is lower overall height. Torsion bars require internal volume which gives extra height to the tank.Hydropneumatic units sit outside the hull so it can be lower.
Hydropneumatic suspension units are only on the outside, thus the inside space cleared can be used for better mine/IED protection.
i'd say at 6:10 the tank in front of the shot , on the right side of the tank from the crews perspective, roadwheel 5 ( counting from the front) seems to have a dark patch on the wheel rubber witch might indicate oil leak from the suspension or its broken rubber or whatever they put around those wheels. also it looks wobly but might only look like it due to the dark patch on it
levoll11 Yeah it looks a little off. lol but what do I know about tanks? I'm infantry
i'm neither lol, just a civvie
levoll11 haha no it's not that one :-) try again and thanks for watching!!
Great vids as always ! Shame I can't support you on patreon yet!
Spooky Pumpkin you watching is enough support as is :/) tanks so much for watching!! Hope you have a great day!
What is the name of the software you used to simulate the suspension of the Challenger 2 and King Tiger?
how about suspension system of the tiger/panther tanks? from an engineering standpoint and an ethical standpoint? I guess what i'm asking for is specifically for those tanks, and how it effected the vehicle positively and negatively. For example, the number of torsional bars and the placement of road wheels, exc. Thanks!
what is Torsion bar with hydraulic dampers suspension system used in Tanks?
Suspension is quite possibly the single most undervalued system discussed in regards to tanks.
When the subject comes up, i repeatedly see the Horstmann suspension mentioned as one of the most underused types, at least in a historical setting.
Transmissions are also undervalued. They're extremely important on a tracked platform.
Did they do anything in that Mk4 so as not to asphyxiate the crew from engine fumes?
nice video
my dude thanks! :-D I am glad you liked it!
What are the little black things you see mounted in groups of 5 on either side of the gun?
Hi, how about Bose electromagnetic suspension on tank?
Are the road wheels on a torsion bar system offset from the opposing side? like are the right wheels slightly farther forward than the left because of the bars not being able to be in the exact same spot?
Yes.
why does no one use external systems like on Sherman , centurion, conqueror anymore?? external, easy to replace
also any chance a video on ammunition types and their uses. also perhaps their evolution, shells started WW2 with 2pdr, ecnded up 90mm or bigger and now 120mm and huge and must be a pain to load inside a tank. also love to know how HE from artillery affects tanks when they land close but don't hit
I think it was on the APC at the last wheel? Idk, I have no idea what I'm looking for.
What dose the t90 have? I seen it jump and don'tknow how it survives the jump!
2nd method to test is a torsion bar has snapped: Tap it with a wrench.
you will hear a metallic metal on metal sound as the torsion bar vibrates, and you should be able to hear if this sound vibrates along the entire length of the bar. If the bar has snapped somewhere then you should hear the difference.
Of course this requires access to the torsion bar. Not sure how easy that is in a tank. In LAVs it requires crawling under the vehicle (something you will be doing anyway).
Shane Rooney yeah exactly :-) good point. But in the tanks as you mentioned you cannot do this. Tanks for watching! :-) please share the video around
how do you damp the torsional bar? hydro is self damped. which vehicles still have torsion bar?
NoFaithNoPain warrior does :-)
At 10:25 the right side, station 1&2 are failing.
After driving the tank of the small hill, the front of the tank didnt pull up , but wen the tank parked and keep still on that upwards hill, the weigt of the tank pulled up the tank. NOT THE SUSPENSION!.
I hope that its the right answer.

Im not sure what type of torsion bar suspension the Leopard 2 uses, but it's incredibly smooth offroad, which I guess is also the reason the Leo 2 consistently scores best during the 'on the move' shooting exercises. Do you have any knowledge of the German system Matsimus?
Leo is coil spring like e100
4.11 which app are you using for that demonstration of hydrogas suspension system.Pls tell me the app
What software was used for the tank simulations? Are they real time?
I should give you a "thx" once in a while. Since i like your vlog pretty much. :3
Well "thx" for watching.
I was hoping for a little more info in regards to hydro pneumatic systems, especially if you have first hand experience. As with the layout and plumbing, wether there are electronics involved or reservoirs of any kind. The torsion bar system on the other hand is elementary. I mean even Chevy 4wd trucks have had those since the early 80s, if you count the S-10, and of course tanks forever,. With the the Gas system I thought it added benefits in regards to real time adjustability and with leveling and raising and hull lowering etc. Then again If I remember correctly that European Citroen brand cars introduced some sort of hydro pneumatic suspension 50+ years ago so neither is really new.
