  • Most of us enjoy the smooth and effortless feeling of driving in an automatic transmission car. The driving is effortless because you don’t need to worry about gear changing and you don’t have a clutch pedal to operate. In an automatic transmission car the work, of the clutch pedal, is automatically done by a hidden component, which is truly an engineering marvel, the torque converter. The torque converter can even multiply the torque. Let’s see how this purely mechanical device performs its tasks.

      And now with electronic enhancements. My first car (with auto trans) had three speeds. My latest has ten. Plus, shift points are electronically controlled. If I switch drive mode from, say, Comfort to Sport, it is as if the transmission was swapped out. Could almost say the same for the engine and suspension.

      It's a good visual demonstration, but some things are left pretty vague. For example there's a longer 19 minute video on youtube about torque converters, without visual animations, but the guy explains what the lock up clutch at the end actually does. Here it just vaguely states it's purpose. But what it really does it only activates when the highest gear has been reached, aka cruising speed. At that point you don't need torque converting and the components can spin together without loss of power. But it doesn't function at any gears below top gear and when the car is getting up to speed through the gears.
      There were a few other things left kind of vague in this video, but watch that longer one which has about 2-3 million views to get more detailed explanations.
      It does make you wonder though if people can come up with complex mechanics like this, why don't we have anti-gravity devices figured out yet ;p

      Is the locking mechanism only for efficiency? Or is the energy loss significant enough to nessesitate it? I'm thinking for tractors, military, and other off-road applications far from any sort of workshop: simple is worth a small efficiency loss.

      Early skid steer loaders only use a converter and no transmission. Machines like my track loader use a torque converter coupled to a manual gear shift transmission.And they can not understand the converter used in there car. A fluid based pump powers all machines built from around 1960.

      @bfrd9k Před 11 měsíci +3

      Helps to understand the fluid as well. It is a hydrodlic fluid, meaning it doesn't compress, it also is a lubricant, and a coolant. The fact that it doesn't compress means that when its slung from one side to the other, it is very thick and acts somewhat solid. The more momentum or energy, and amount of fluid being slung at the opposite side, the more pushing power it will have.
      Everyone knows what its like to be blasted with high pressure water, now imagine i stead of water its a high pressure liquid that doesn't splatter, mist, or compress under pressure. It acts more solid.

    The torque converter was developed by humble engineers at "Sachs" in Germany. They are the ones who should be remembered! They then had to drive around in ordinary cars.
    Their ideas had to be converted into solid steel.
    They didn't have access to software or 3D design simulation!
    Though modifications have been made to the original design, it had to work, more than just spinning around to be put into production.
    It multiplys just torque and not riches!

    The lockup clutch is the best thing they've added to automatics. For those who don't know, older automatics in some vehicles did not have a lockup clutch. The converter was a constant slip or steady slip design. Very common in 70's - 90's medium and light duty diesel commercial trucks and buses with Allison automatics for example. What does constant slip feel like? Feels the same way your modern automatic behaves in cold weather when you first drive it while the transmission is cold. It takes about 15-25 minutes of highway driving to warm up the transmission enough to trigger the lockup clutch and when that happens the engine rpms will lower slightly and it will behave like a manual transmission since there is a direct connection between engine and transmission. Older automatics feel like "they're cold" the whole time being driven, constantly slipping and inefficient by comparison.

If you put the transmission in drive, hold the brakes, apply throttle - the engine rpm will only go to the stall speed. Inside the converter, the way it is built, determines stall speed. Drag racing prefers higher stall speed, for instance, because the engine is allowed to rev to a more powerful speed before load is applied.

      @@juhmeldavis4756 Especially in automotive features, an engine operates on the principles of a pressure differential albeit the fluid is a gas instead of a liquid. The water pump, fluid dynamics. Power steering pump, fluid dynamics. Brakes, fluid dynamics, usually vacuum assisted linear pump (the brake pedal is attached to the master cylinder which has a piston inside for pumping the fluid to the brake calipers, which also have pistons) Almost all of it works on pressure differentials and fluid mechanics. Even the crankshaft bearings which have no moving parts except for the oil that is pumped into them. A vehicle usually has about 6 pumps in total, some more some less. Not including the alternator which basically is a pump but the fluid it's pumping are electrons and not a liquid lol Very similar concept in electronic circuits to hydraulic circuits

    Hello ??, this is the best visual explanation I have ever seen on how torque converters do their magic! I'm 70 and a neighbor of mine back in the 1960s gave me a training manual on the newly introduced Ford C-6 automatic transmission ( I still have it) so I could better understand the trans in my 1966 Cyclone GT. It explained the whole principle of torque converters very well also and I have always understood whats going on ever since I read it. The one thing you did not mention that it talks about is how under high stall conditions the fluid speed gets accelerated in every pass through the pump, turbine, reactor and back to the pump. I have sent msgs to other people, converter mfgs, trans specialists etc asking if they knew how fast, what speed the fluid might attain in a full stall condition. I got reply's back several times but never really an answer to my question, as they said they really didn't know .
    Do you have any idea of an answer to this question, do you think it's ever been measured or calculated? I still have a cut open torque converter in my garage attic in case any one I know wants an explanation as to how they do their thing. This whole topic is why I feel in many ways that a torque converter hydraulic automatic trans is better than the dual clutch automatic / manual transmissions that are becoming so popular today.
    Sincerely, George

    So just to clarify for myself, the reactor's job is to help the pump by making sure it receives swirled fluid, and this is done by the one-way clutch. Also, in a way, it is good that the output fluid from the turbine is not swirled, because that means it absorbed most of the swirliness from the pump and converted it to rotation to the transmission. And then that's were the reactor comes in and adds the swirliness back to help the pump.

      When a valve opens or closes it engages or engages a brake on one part of the planetary gearset. For instance brake the outer hub and you have the gear ratio between the shaft and planetary carrier, brake the carrier and you have the gear ratio between the shaft and hub.
      Old transmissions used pressure differentials caused by the increase in speed to open and close the valves, modern transmissions are all electronic.
