How a Continuously Variable Transmission Works

Here's a look inside a continuously variable transmission and how it works!
A continuously variable transmission uses a steel push belt to transfer power from an input variator to an output variator. The diameter of the belt's input and output shaft varies, which determines the drive ratio.The variators are hydraulic cylinders that have a cone shape to the pulley section that interface with the belt. When fluid is added, the belt is adjusted to ride on a larger diameter. Meanwhile, fluid is released from the opposing variator, allowing the belt to ride on a smaller diameter. Both variators must be adjusted together for belt tension to be retained.
A planetary gear set on the output variator allows a change in direction for reverse gear, as well as a two speed step to increase the range of the CVT. Similar to an automatic transmission, a valve body controls how much fluid is applied to the variators, planetary clutches and torque converter.
Typical failures with CVT's include overheating - which is likely due to too much load on the unit from driving uphills, overloading the vehicle, worn fluid or towing conditions.
Furthermore, if belt tension cannot be retained, the belt will slip and shudder. Finally, since the belt itself is fragile and made up of hundreds of pieces, any minor alignment or over application of torque can cause it to catastrophically disintegrate.
he CVT in this video is a Jatco CVT-7 unit from a 2020 Chevrolet Spark with only 2000km on it. The vehicle was in a collision and the engine and transmission were working units when removed!

[@DanteTheAbyssalBeing]

It's amazing you can transmit any power at all with such a small surface area between cone and belt. I know CVTs are usually stuck on low power engines, but I'm surprised they don't just slip the moment you give it full throttle.

[@speedkar99]

I agree but think of the hydraulic pressure in the variators squeezing on that belt!

[@mantatrip9319]

Oil pump boost preasure from 5 bar to 50. Cruising speed between 0-15 kW can be 7 bar. Kickdown will first boost oil preasure than engines throttle. Cvtz50 app and obd2 are like movie for me while driving. Locking torque convert are also depended of throttle, hills, mass, oil temperature.... Interesting machine. The Throttle pedal controls only the engine, gearbox reads engines parameters, gyroscope, speed and insertion. Downhill is also interesting, it revs higher to steepest downhill to keep the speed....

I'm daily driving on a Honda CVT with over 112K miles and zero issues. Fluid changes are important! I do floor it from time to time for fun, and I'm not babying it on the highway passes by any means, but my engine peaks at under 190 HP. I've learned from the tuning community the transmission can handle up to roughly 250 HP, but I don't have the money to verify that. As far as torque tolerance in general goes, though... More modern CVT-based setups often have a single-gear automatic for launching the car from a stop, to reduce the load on the CVT from the sudden massive torque of moving a stopped car. I don't have that on mine, since it's a 2013. What shocks me about the metal belt CVTs is that there aren't any visible notches or anything on the cones for the belt to grip, despite the fact that belt slippage could potentially kill the transmission. I've also seen a teardown vid of a Honda CVT from a CR-V. It has some similarities and differences. In that video, the belt had slipped. The only visible indication of how it had failed was some scratching on one of the cones, as the other cones had nice, evenly machined surfaces. No debris or anything.

I remember in the early 1980s someone heard my brother was a brilliant engineer and gave him a bright orange, low mileage Volvo 66 (a rebranded DAF) with a locked transmission to fix, they said if he could sort it out he could have it for free, because absolutely nobody could figure out what the problem was and why it never ran right, not even the main dealers. He puzzled over it for weeks, took things apart and studied them, then rebuilt it and observed it working, trying to resolve various problems. He had me listening to vacuum pipes while he worked the controls until one day a pipe nearly sucked my brains out and he suddenly understood how it worked! After drawing diagrams on paper and retiring to bed he was up early next day and had it working perfectly within a few hours. That car then ran faultlessly for years and he even designed an electro mechanical modification so that he could manipulate the gearing at will by flicking a switch. He said at the time that he had various ideas on how to improve it and that he believed that one day most cars would have cvt transmissions. Shame he lost his way later in life when he decided he was going to be a famous pop star. Don't know what eventually happened to the car and alas these days we don't speak, because as you may have gathered, he's a nutter!

Many mechanicals of the drivetrain in those cars were external not like CVTs and differentials of today. Really worth a visit. They have old open sectioned CVTs on display.

[@LawpickingLocksmith]

Very interesting! In 1959 the Dutch DAF model 55 used 2 belt driven variators to skip the differential. It was the first car to be allowed to be driven by the disabled unable to operate a stick shift. We had a belt driven variator in a drill press and Italian Piaggio was experimenting with their Ciao series of mopeds. Yamaha has great success in their quad bikes with it. Going to steel belts, I had my reservation on how the oil is going to stand up with heavy loads. Personally my choice on auto reliability goes to Toyota Borg Warner units. Looking into the future, Peter Rawlinson has placed his differential right inside the axle of an electric motor. This mimics Subaru's claims of equal torque on each wheel.

At mark 15:44 you explained how the “lock up” occurs... so when that happens is when u put it in gear and you feel a bump or thump “engagement” . How would you lessen that hard engagement? And what causes to get worse? I have a Rogue and it sometimes does that.

[@speedkar99]

If the hydraulic fluid is being sent too quickly it will cause a hard shift. That could be due to the programming but also if the clutches are worn and just slip and grab. Fluid condition and temperature may also be factors in addition to engagement speed. Finally check your engine and transmission mounts

Most modern CVTs have simulated gearshifts for a more traditional feel. It’s basically a software thing if I’m not mistaken. Although Toyota’s “Direct Shift CVT” for 2.0 engine in Corolla and Corolla Cross there’s a physical first gear for better acceleration at launch and then it shifts into CVT.

[@ahnafzahid9450]

Do all CVT cars come with a torque converter?

[@speedkar99]

Yes. eCVT's on the other rhand have just a flywheel.

[@thx1138guy]

@@speedkar99 Wrong. Honda Civic CVTs don't have a torque converter. They have a start clutch.
