The engine, the clutch, transmission and drive shaft transmits power through reducer, drive down its rotating speed, torque increase, and the moment passed to driving wheel axle shaft; Under automobile rear axle load; The road through the leaf spring reaction force and the torque to the frame; Car when driving, plays a role of main brake rear wheel brake, and when parking, parking brake rear wheel brake.
