Exactly! This is the first time I really got it. A huge part of my job is testing and adjusting closed loop hydronic systems with centrifugal pumps. So I am quite well-versed in pump theory and thinking of it like this makes so much more sense.
Ten years ago I was looking for this animation, and there was nothing out there. As I thought about it I realized I wasn't capable of animating it nearly well enough to illustrate all the concepts, especially as far as how it locks up at high speed. Bravo, you've dramatically raised the bar.
The Automatic Transmission Fluid has just the right viscosity to transfer the power between those impellers as well as pressurize the gear shifting valve body controls for smooth shifting as you accelerate through 1st, 2nd, and Drive. Pretty incredible design when you really look at it. Excellent video graphics.
Love the animations! It would be nice to see some arrows pointing and explaining as the animation happens though. The explanation is often quite fast and its easy to lose track of what is being spoken about! Thanks:)
Good animations, and you explained all the elements, however I think it was a little too fast. Maybe you could have explained a little more in detail the torque converter part, which is more complex.
Fluid couplers are found on forklifts for example. The lift needs to keep running hydraulics if the wheels stop against a curb - the stall speed is @ idle - can be coupled to manual transmission. Torque converters multiply the torque & provide a stall speed to assist acceleration. They are very different in design & application. Nice video, keep them comming!
I have seen lots of 3d videos explaining how a torque converter works, this is the first one that shows the actual reactor wheel and explains how the torque converter changes state. Well done!
these were used down the pit for the gearbox to motor connections on the conveyor belt system, they were huge, some 6 foot high weighing many tonnes and filling them up took many gallons of fluid which was a white oil and caused terrible skin conditions if you come into contact with it, an instant dermatology condition, they were very reliable, in fact, I can't think of one ever breaking down and they ran 24/7 none stop for decades except for the summer servicing and fluid top-ups,
And what's interesting as well, is Jim Hall of Chaparal racecar fame, made surprising use of coupling a torque converter to a two-speed manual transaxle in some of his racecars. I believe the Chaparal 2B was the first.
Back in 1964, my ford with an automatic was a few hundred more with the auto option over the manual transmission. I prefer the manual but I see why with that jet engine like turbine technology for the 60's!! Makes sense 🤔 👍
People that say they prefer a manual over a auto are like saying you prefer horse and buggy over a car. Its obsolete. And yes I been driving both for some 30yrs and auto save so much time in traffic. I use to drive in work 40Km and the auto was 20 minutes faster in heavy traffic jams.

Great explanation of a seriously awesome kind of coupling. Never knew these existed! Also one of the hottest fluid Sims I've recently seen! Great video mate!
Ok. So I get that the liquid from the other fan spinns the other fan. But where does it come from??? The liquid? And how does it come there? Is it pre filled or does it flow from the gearbox or? And how does it seal inside when the parts are moving?
The liquid is usually the transmission fluid itself. When transmission is filled, some fluid goes into the torque converter. In old vehicle revival, since the tranny is dry sometimes, the vehicle does not move until the fluid is put into the transmission. This is the reason why...
I imagine in most cars neutral in automatics is when the torque converter has minimal fluid in it. And or a disconnect of the forward and reverse engagement clutches for a cvt transmission
see Voith. they pioneered the technology over 120 years ago. I worked for them for five years. it was quite amazing and torque Converters and fluid couplings , components of the same variety with the Subtle differences explained in the video . some are used in buses, others are used to non mechanically power any drivetrain from ships propellers to conveyor belts anything with a high load or high torque requirement as it runs at full capacity like a 3 km long mining conveyor belt and how to start it up under no load conditions and then slowly ramp it up without destroying the drivetrain or overloading the drivetrain or tripping the electrical power supplying the drivetrain from the gearbox to the electrical motor soft starter etc. many favour electronic drives like vfd, variable frequency drives or frequency converters but ultimately the mechanical device pioneered 120 years ago is still the best way to handle massive loads in a mining environment or any other heavy industry like steel production.
I still do not understand how the reactor or stator as I've heard some people call it, increase the torque output. Does it just direct the fluid from the the turbine to the impeller into the impeller blades, reducing friction, energy loss et cetera?
It spins the fluid flow. The pre-spun particles enter the pump wheel, which spins them even more, which ultimately allows you to increase the torque. At the same time, the rule of mechanics is observed, we win in effort, we lose in movement. The output shaft will have increased torque, but its RPM will be lower.
Ahhhhh now it makes sense! Thank you. 🤗 The animations are great and you explained everything but to someone who has never seen it work it was a little too much information and not broken down enough.
Why don't they use stators (reactor wheel) for directing the initial flow from the pump to the turbine? It seems a stator in either flow path will increase torque, and a stator on each will increase it further. And is there any air or vacuum in the torque converter or is it filled 100% with fluid?
This is great and all but it doesn't show a stater support seal. That little $2 seal breaks or deteriorates you lose pressure in the transmission and it grenades itself takes out the pump the torque converter possibly burning up some bands or servos.. what sucks is it cost quite a few hundred dollars cuz the transmission has to come out to replace that seal
I came here to find out how the fluid gets into and out of the torque converter.....the cycle of the fluid. Might help knowing this when I change it out.
Or simple the movement of boat, hidden movement way like this? Looks maybe cheaper to have 2 or more will be nice? Easy to make boat turns like have left, right, easy control from front?
Or you could say the torque converter (torque is the French word for twist...) forces out high velocity fluid to hit the blades of the turbine input shaft....and then the transmission moves the driveshaft to power the axles that are attached to the wheels
I always think bad of torque converter because the parts don't really touch each other and rely on fluid to transfer power....but when I think of these thing can fly a plane....I can speak no thing as well😂
An automotive torque converter also uses a friction gear to lock up. This allows you to increase the efficiency in some modes. This friction gear wears out over time.
The vanes bend and break over time and use. This is what causes them to quit working generally. The lock-up clutch is great because it reduces heat and takes the load off the fluid. It is also a wear item, especially since most automotive OEMs care about smoothness more than longevity so they slip the hell out of the clutch during engagement making it seamless to drive. The lock-up clutches are all hydraulic or electronic activated, there are no springs in them like the video showed.
Maximum torque multiplication is when stator and turbine are at zero RPM, (stator = stationary) and impeller is at maximum design "stall" RPM. As turbine speed increases near impeller speed, the stator (mounted on a one way clutch, a.k.a. sprag) will rotate (one way) and allow the torque converter to be just a fluid coupling with no torque multiplication. Turbine and impeller will never be 1:1, this is why modern converters, (post 1980's) have a lock up clutch added.
And that my friends albeit a mechanical marvel, and useful at times. Is why I hate the automatic transmission, that and computers and improperly set valves making a limited range transmission, ie fuel economy cars with 4k Trans won't be able to properly Rev match or maintine a high rpm under low throttle for cornering. 99% only good for traffic. Which is kinda the point.

Great analogy. It clicked as soon as I saw them together
Fluid moves your car up into the air for an oil change.

That is not how it works.
A fluidic torque converter is a self contained unit with its own fluid sealed inside.
On some transmissions yes, on most modern transmissions they are combined units

Can you have an idle setting on a fluid coupling where the turbine wheel isn’t affected by the rotation of the impeller?

That was a lot of words, but I think I understand now.
Simple explanation 😀
The fact that somebody even came up with this
Very cool video !
But I'll be keeping my third pedal.
No mention of the fluid's shearing strength and stall speed.
I still cant understand how this just "knows" when you are braking. Wouldn't this be fighting against the brakes when you try to stop?
Important to note the most basic concept ... that fluids are NOT compressible. If they were a fluid coupling would fail.
This is great and all but it doesn't show a stater support seal. That little $2 seal breaks or deteriorates you lose pressure in the transmission and it grenades itself takes out the pump the torque converter possibly burning up some bands or servos.. what sucks is it cost quite a few hundred dollars cuz the transmission has to come out to replace that seal

Is it the same hydraulic-motor?
@0:40 aren't the turbine vanes angled the wrong way?
How is the torque converter not leaking out the liquid

minor nitpick, but shouldn't the vanes on the turbine at 1:05 spiral the other way?
Yes, I made a mistake when I did the animation

why it doesn't use a normal clutch ?
Wait... You still need transmission?
this... is... nile gray?

حرام عليا اذا فهمت 🙂💔
Still puzzles me how the fluid is sealed.
Just when I wonder how they work, this pops up
You missed the part where the stator starts turning which cases torque multiplication
Maximum torque multiplication is when stator and turbine are at zero RPM, (stator = stationary) and impeller is at maximum design "stall" RPM. As turbine speed increases near impeller speed, the stator (mounted on a one way clutch, a.k.a. sprag) will rotate (one way) and allow the torque converter to be just a fluid coupling with no torque multiplication.

So a centrifugal pump is just a turbo
The turbine in a centrifugal pump is heavier than a turbo so it's like a flywheel also
I still don't get how the reactor works. I mean, I have a suspicion, but you haven't really explained it, it might need an additional video.
I always wondered what magic was inside those things
