These guys are talented engineers
This is why soviets with slide rules achieved better results than Elon Musk today.

@@FrozenHaxorelon musk give us nothing.....
That was sooooooo awesome. It is so friggin epic seeing how shocks works. Thanks soooo much for sharing this video with Us Garage 54.
This is NOT how a shock works. They've just did a gas spring. Real shock has some valves in the piston. And are not completely filled with oil.
It's close enough though!
Heck yeah bro, the device worked well, and Garage 54 did a great demo of how cars absorb bumps and stuff. It would be even more friggin' epic if they broke the glass piston itself. :) Imagine the oil spewing out out at 90 psi (6 bar) or whatever the air or oil pressure is. I'm a man, we like when stuff fails*, as long as it isn't our own. That would add to the "shock" value, pun intended.
*Disclaimer: Only in televised series or YT videos.
@@GrandePunto8Vbecause they didn't design an engineering marvel like koni does doesn't disqualify their item from being a shock absorber
Npc
These guys hit a homer every now and then
If you ask me, every now and then is every upload
I've never seen or heard of anyone using a mig welder to cut glass. Very cool and interesting
They gotta make a transparent Lada with all the other parts they made so far. It'll be like that transparent Honda s2000!
they are close to do it, only a few parts that need to be solved
i wish for transparent distributor cap, i saw one for toyota corolla 4k engine in ebay once but not anymore... it was not cheap tho...
@@lokelaufeyson9931 the engine block they did wasn't 107%.. too bad too.
@@MrBanaanipommithey did one, but I don't knnow if it's on the english channel or not. :edit: it's here. it was 8 months ago.
@@fryloc359 forgot that lol, but i actually meant one to buy ;D
You guys are the greatest it gives people with no mechanical background an insight to how these things work. Its also fantastic experience for the young mechanics ,they are terrific. Keep up the good work and warmest greatings to you all from Melbourne Australia.
AGREED!!! 👍
The air gap solution is basically like the spheres in Citroen hydraulic suspension (or the British Leyland Hydragas suspension), but there's an experiment for you, DIY hydraulic suspension, whether like the Citroen hydraulic system where you can raise and lower the car, or BL's Hydragas "set & forget" setup, retrofitting them to something that lives its' life on coil or leafsprings would be a fun test to see the difference... :P
Sorry if this sounds ignorant but couldn't they solve the pocket issue by turning it upside down and allowing the air to flow upwards?
@@Cheeky-Biscuit They probably could have, but as with all things experimental, it was never going to be a perfect design, plus they were trying to keep the oil as air free as possible so that it looked good on camera being all clear, thus separating the two sections... :)
@@twocvbloke fair enough thanks for the explanation
Amazing
@@Cheeky-Biscuit The rod changes the volume inside the main cylinder so that wouldn't work. Their solution is how some normal shocks work. Cheaper shocks will sometimes just allow an air pocket within the shock. Expensive shocks have an extra little reservoir to contain the pressurized gas.
I had my safety squints on the whole time
Yet another amazing video! Bonus point IMHO for being thorough with the foaming issue! Such easy knowledge transfer.
You're welcome! I peppered the last video a bunch with gas charging
AYO that mig welder hack is out of this world, why didn't I think of that?!
@@antonszvezdovs ouch. At least it got cauterized?
As someone who builds aftermarket shocks for a living, I appreciate this video so much 😂😂😂❤❤❤
Edit: @7:30 the term for that is "cavitation" and can happen even when no air is present. When the air rushes through the piston, it created areas of extremely low pressure along the trailing edge of the holes. It's such low pressure that it makes the fluid turn to it's gas form.
You guys are GREAT!
And funny.
Love your channel from here in Missouri, United States.
Keep up the great work!
Very cool. The shaft displacing oil is an aspect I wouldn't have considered. Now I know why the small diaphragm was necessary in the RC car shocks we built back when I was younger. And also I understand why more air pressure stiffens the forks on a dirt bike. I couldn't understand it before, since the air isn't acting on the shock piston with a bypass hole in it. The air disapating in the oil is cavitation.
Dirt bikes have air springs which indeed are acting on the stanchions. This is not the same setup, the springs on this car you can see behind the shock.
EDIT: i am an idiot motorcycles dont usually use airsprings.
@@Christophe_L no. They have coil springs in the front forks. The increase in pressure is reducing cavitation to stifen damping. It doesn't raise ride height like Increasing spring rate would.
@@jasonbirch1182 While a lot of road bikes have coil springs, most dirt bikes have airsprung forks. But it could be the case that your bike in particular had a coil fork in which case I fucked up :)
EDIT: nope, motorcycles dont usually use airsprings.
@@Christophe_L I'm not aware of any air sprung forks. The newest set I have is off a 200(?) yzf426 so maybe some newer bikes are, but I don't think that you are correct.
Edit.
After doing some quick research, you are not correct. There are some air sprung forks available but not factory stuff. It's experimental high end race motorcross damper builders trying air. They aren't practical for many reasons. Leaks, condensation from refilling with moist air. Heat rapidly affecting pressure. Non linear spring rate as compression increases. Springs are great. They just are a little heavy. So they keep trying to make air work.
@@jasonbirch1182 You are indeed correct and I apologise and self-flagelate profusely. I will edit my comments to reflect this. I was going by my MTB knowledge (where air forks have become more prevalent than coilsprung ones), and knowledge passed on from not very trustworthy sources plus lazy googling. I apologise again!!
how hot did the shock get? Shocks work by converting linear motion into heat to dispense the energy of the shocks.
But they have just did a gas spring. Real shock has some valves in the piston, oil is pumped via orifice (there is your source of heating). And almost 100% fill is a mistake.
That’s now how shocks work.. heat is a an unwanted byproduct. Watch the video again to see how shocks work.
This is exactly how an IFP (internal floating piston) shock works except that there are flexible washers/ shims in the main piston that also control oil flow for compression and rebound. The fluid cavitation doesn’t allow the shock to dampen as well so nitrogen pressure is added to the IFP chamber and the result is very well portrayed in this video. Excellent job and video!
Using the mig wire got a like straight away. Awesome idea
It really needs a one way valve with the biggest hole in the piston letting it move downwards easier than upward.
That mig gun to cut the tube worked better than I could have imagined
Excellent work. I am very impressed. I would love to see four of those on a lifted offroad vehicle. Now that I have seen such good results I am sure this type of setup could work on a rock crawler type of vehicle. A high speed offroad vehicle such as one that might be used in the Paris Dakar rally might be too much but the cool factor would be out of this world. Great job fellas 😎👍
This was a really cool episode. Ingenuitive and informative. :)
15:08 Impressive! The bottom end even moves apart from the upper part, impressive!
man the sound track for this one was fantastic
Great episode! Now the next step is to make a dual tube shock absorber!
The glass cutting is flippin awsome so simple but genius
Excellent video. Saw things I'd never have thought about or believed. I look forward to your next video. Keep them coming guys.
You can compensate for the rod area by making the piston equal area which means making the rod go through both end caps instead of just one.
ingenious way of cutting the tube.
The cavitation in the top is neat
I enjoy your videos very much, you really have some skilled people at Garage 54!
This is how a front strut on most aircraft work. I like what these guys do, thinking outside the box without losing the box.
Well done again love this transparent experiments on various functions on a car keep them coming
What a great experiment! One of the best so far! Keep the good work up!
so cool how you engineered around the air problem
Great video! It was much stronger than I expected.
I would've taken some hose clamps or zip-ties and lined the tube every couple inches or so with it. Not so tight to disrupt the inner shock, but enough to support the pressure in the tube. Otherwise, this is fantastic and I love seeing this work. I thought the gas buffer at the bottom added a nice, high-performance touch. And the guy riding in the trunk, had the BEST seat in the car!
Looks like the glass tube didn’t need any support, so the zip ties would be completely unnecessary.
Cool video, see through shocks are interesting.
Unbeliveveable-what did you just do-pushing it to the limit one more time- even more props to translator
Outstanding work!
Very nice. Awesome to see the inside of these in action.👍👍
Just started following you guys, love the channel and the cool stuff built! Keep up the great work.
I always love watching these!!! So interesting the things that are thought up, and then you get to see it in action, that’s really cool love these!!!! Thank you for the time and info!!!
Matter fact, I’m so inspired, I’m going to try this on my wife’s car, lol!!!
Please build four of these, in steel, and give it a test. The large volume dampers seem great!
This channel is great, I love the backyard engineering.
Absolutely a 107% success Vlad . Because those of us that aren't shock designers learned something about shock absorber technology here . This was a real scientific experiment . Good job guys . :)
This channel is worth its time in gold thanks for all the hard work for us
Thank you for this awesome content, I’m happy you guys can keep this show going given how the world is.
I want some G54 shocks right now🤣
That has to be one of the coolest things ive seen through. Top job my friends.
Good job guys! Awesome video.
the guys working for him doing this stuff are going to have a very interesting resume
😂
This channel is so underrated. I honestly rarely comment and like any videos but this channel always deserves it. Thanks guys.
fokkit that was epic! DAMN. And such a cool colour for the oil. Well done guys.
i agree with others here, very awesome to see indise of a shock that is moving! thank you!
OK, but this was just a gas spring (not proper shock absorber).
Ever since i showed my automotive tech teacher these videos.. we implemented these videos in the program
That was super cool and informative
Gosh you make quality content, I thank you!
Easiest way to purge the fluid from the shock was to put a bleeder such as a zerk fitting (grease fitting) onto the shock. Would have released the air as well as the extra fluid.
Wow! I think you have made another innovation to an auto industry, my first and only worry is if in case that glass tubing would be hit by a fast moving stone or anything solid like a nut or screws that are made of steel. Hmm. Maybe a wrapping of chicken wire with a clearance of about an inch from the glass tube would do the trick.
Another mind blowing vid, hats off to you vlad 🫡
Genius level stuff using a welding machine to cut the glass 😮
This one was awesome!
that's why i love this channel! no one can beat this channel more amazing ideas!
Another great interesting show! Thanks for the view of a shock's working innards. An extra seal silicon-ed in at the top would get rid of that air pocket.!
But...they've just did a gas spring. Real shock has some valves in the piston!
Ladas sure are fun, huh?
Excellent video.
Machining that piece of flat steel into the cylinder caps was great lol. Love the content.
This channel is incredible!
well guys you all did it again with this idea. not only was this fun it is functional as well good job . well thought out guys.
These guys are ridiculously talented
Sick Channel G54. I finally know how it works
Very interresting!. I thought the floating piston would have had more stroke tho!. What you did is a "De-Carbon" shock principle. They inflate the secondary chamber with Nitrogen tho, to keep the pressure more stable with temperature. The air that mysteriously appears is in fact Cavitation. It is BAD for a steady dampening action.
Nice, one of the more practical experiments youve done.
Incredible empirical science❤
The temperature of the shock oil is also an important part to observe the energy.
It would be interesting to see all the shock's like that one and test it with speed and hard cornering and braking to see if it's better than conventional shocks.👍💚💛❤️
Amazing to see the oil on the top chamber ”boils” during compression.
That glass cutting is genius
21:04 Now I can say that I've finally seen oil cavitating :D
Thanks so much!
Great visualisation of damper cavitation !
True science in the works. Love it!
You guys should try to set an official Guinness World Record utilizing all your transparent modifications on one car? For the most transparent Classic Car Built
That shock came out great, good work!
Where's the "shock"? This is gas spring mostly.
@@GrandePunto8V the plastic disc on the end of the rod... it has holes drilled in it that let the oil flow through.
It's a shock absorber.
If it was a gas spring there would only be one piston, and it would be all air.
Sooo very good as always !
You guys should try to recreate Bose's suspension. It's basically a linear electric motor instead of springs and shock absorbers.
the foaming you can observe in short instances while the shock is compressing is not air. It is vacuum bubbles cavetating. Explanation:
While compressing at higher speed the orifice in the plunger makes so much resistance that instead of keeping up the flowrate for the movement, the air camber is compressed. While this happens the increase of volume in the upper chamber is more then the volume of the oil entering, developing a strong vacuum. The missing volume is filled up with vacuum bubbles, and the disappear they instance the vacuum disappears.
Awesome experiment.👍
nice setup. the air can also have a spring effect
Glass shocks would be really cool for car shows😅
Great video !
Son increibles, muchachos!!!! excelente trabajo!!!
Great experiment! 👍👍
INSANELY AWESOME!!!!!!!!!!!!!!!!!!!!!
7:25 cavitate / cavitation is the word
Foaming = Cavitation
The second piston is known as IFP.
The IFP should be backed up with high pressure. Usually the chamber is filled with Nitrogen gas.
To purge/ bleed all the bubles out of the oil u should put an connical hole at the top of the plate, than u have to purge the air out of the system and than put an connical end screw in the bleed hole.
And yes, the system was cavitating on peak bumps even with the IFP being "inflated". Thats cuz the pressure was not enough and there was a small bit of air inside the upper chamber.
Please don't consider that as hate!
Great entartaining videos!
Keep up the good work.
It still worked & all, but shouldn't the air/compensation chamber be at the top? Just to keep things separate, I mean? ❓
That was pretty darn kool
Awesome great content guys keep it up
Maann I love this channel. This channel helping me so much than my teacher 😂😂
Great video
a valve spring from a Lada engine, or something similar you should put in the compensating chamber
This was soooo satisfiyng!
