How Does Torque Converter Make Cars Moving?

An automatic car has something called a torque converter. For the car to move forward, whether manual or automatic, torque is needed for the initial momentum. The torque converter is a fluid link where its job is to connect the engine to the gearbox and the gearbox to the driven wheels.

The engine is connected to the gearbox in a bell housing. This is where the torque converter is. The engine's flex plate is also connected to this torque converter. So the torque converter basically takes the place of a clutch in an automatic car. When the crankshaft rotates it also rotates the converter. This is how the torque converter will disconnect and connect the engine's power to the load being driven.

The torque converter has main components that make automatic transmission successful：

1.The impeller connected to the engine which is responsible for driving the turbine using viscous forces on the transmission fluid.

2.The turbine connected to the transmission input shaft that sends the torque force to the transmission.

3.The stator sits between the impeller and the turbine. It lessens churning losses. The stator redirects the fluid so that the majority of the velocity gets driven towards the impeller which then adds to the torque produced by the motor. It can only rotate in one direction if the impeller and turbine are moving at the same speed. Stators do not apply torque when on a highway, only when coming to a stop or accelerating.

4.The lock up clutch.
