It is transmitted from gear to drive wheels by joint shafts and drive shafts. Generally, power transmission from the gearbox to the differential is provided by a propeller shaft. Its connection is made with cross, cross joint or dry joint. If longitudinal distance changes occur during the springing of the rear fixed axle, the propeller shaft must consist of two parts. The propeller shaft, which is mostly made of steel pipe, should not transmit vibration to the body during rotation. Two axle shafts go to the wheels in rear drive and front drive. In front drive the axle shaft joints must have large deflection angles to ensure the steering wheel rest and the springs working distance. Also, during the large steering column, the turning movement must occur smoothly so that vibrations do not affect the steering wheel. The connection used in this type of structures is made with a joint cross.
