What are the input and output parts of various components in traditional automobile power?

The output part is the engine and the input part is the transmission.

The engine mainly relies on its flywheel for power output. The flywheel is connected with the clutch, and then the clutch is connected with the transmission to realize a continuous closed input and output system and provide power for the automobile.

The principle of transmitting input power depends on the rotation of the shaft. Generally, one shaft inputs power, the second shaft outputs power, and then outputs power to the flywheel through the clutch connected with the transmission and flywheel, and the flywheel inputs power to the whole vehicle. You can also rely on universal transmission devices to transmit power, such as transmission shafts, and directly transmit power without external input or output.
