Chevrolet Volt 4ET50 Transaxle Components and Operation (2011-2015)

Here it is the clutch pack that connects to the ring gear, so we can connect the motor to motor A and if we apply the hi 2-3-4 variable clutch at the same time, we can apply or connect the motor to the ring gear toothed and the ring gear then drives us. The planet carrier, through these teeth drives the transmission gear and makes the vehicle move. Note that we are not connecting the internal combustion engine directly to the engine through the clutch pack. This drives the generator motor B. It is just the planetary gear part of the planetary gear set, so the sun gear is connected.

This is the engine generator. It can go in and connect to the satellite carrier here and power the B engine generator that powers the vehicle. and it will turn the sun gear and the ring gear will stay in place and the planet carrier will turn the housing out here and the planet carrier housing and make the vehicle move or we can go in through the engine and drive the ring gear, or we can go in through the motor a and drive the ring gear, so let me try to summarize it, let's finish, we have an output route to get the power out of this transmission, and that is through the output carrier through the output. carrier housing and rotates the transmission drive gear connected to the center stand, it can be driven by the ring gear through engine A or internal combustion engine, or it can be driven by sun gear and engine B or engine A and motor B and in this In case of motor A it will drive the ring gear motor B will drive the sun gear and we will have a direct direct drive connection on our planetary gear set so that we can switch between motor B and motor A and continue pushing the vehicle in the same direction, the only thing that needs to be loosened is to remove.

The clutch component in all of these problems is the variable low speed 1-2-R clutch here, which is actually a brake designed to stop the rotation of the ring gear so that we have some resistance to the engine B. force when driving the vehicle Okay, I told you that the Chevy Volt

transaxle

is completely different from the Ford hybrid system in the Toyota hybrid system, the only thing it has in common is that it has a single set of planetary gears, but since it can have from one to three different clutch sets. See, these clutch sets can engage or disengage the engine, they can engage or disengage the drive motor generator A or connect everything to the planetary gear set and help the generator motor B drive the vehicle.

It is a unique system and is simply

2016 and later have new versions of this transmission. I hope to get one of these someday, but if I remember the training I did, they reduced the weight and got rid of it, took the drivetrain setup and ran with it. a chain drive setup, very similar to the first Toyota Prius transmission which had a chain drive and then they used the drive gears that GM is using now to make the chain drive go forward and reverse anyway, interesting stuff awesome stream hope this helps thanks for watching have a nice day
