Drive shafts and cardan car Mercedes M-Class (W163)

The vehicle is driven by the transmission of torque from the axle differentials to the drive wheels of the front and rear axles of the vehicle through four drive shafts (two front and two rear). The anthers of the inner hinges are made of rubber, and the outer ones are made of thermoplastic (thermoplastic is more resistant to external influences). Each shaft consists of three main parts: the inner hinge, the shaft itself and the outer constant velocity joint (CV joint). The inner shaft joint is locked inside the corresponding differential assembly with a circlip. External hinges (CV joints) end with splined trunnions, which are included in the splined hubs of the drive wheels. The pins are fixed in the hubs by means of hub nuts.
