The propeller shaft usually connects the rear axle of a motor vehicle with the drive located in the front. This allows you to transfer the drive to the rear axle or construct an all-wheel drive. The propeller shaft is mounted to the provided places with universal joints or rag joints at both ends. It offers numerous advantages over a drive chain. As a result, less maintenance is required and the distance between both shaft ends is easily changed during rotation. Such changes are needed because of the constant motion of the vehicle's suspension. Its dynamics causes alterations in the relative positions of the differential, which moves with the drive axle, and the transmission. The length compensation in the propeller shaft, which thus becomes necessary, is facilitated by means of a rag joint.
