Side output, 4MATIC, general

A propeller shaft (5) is used to transfer torque from the side output (4) of the transfer case to the front axle transmission. The at transmission end universal joint (3) of the drive shaft (5) is integrated into the driven gear (2) of the side output (4).

A 7° spiral bevel gear is used to push the propeller shaft tube onto the joint fork of the side output (4).

The universal joint (3) have to be assembled aligned to each other to ensure that the transferred rotation is uniform.

On the front-axle transmission side the drive shaft (5) is bolted using a propeller shaft flange (7) to the drive pinion of the front axle transmission.

Universal joints (3)

Basically, a universal joint, which runs under an angular offset, generates a non-uniform rotary motion.

If the angles formed between the axes of the propeller shaft tube and the joint forks are equal, and if they are on a common plane, the non-uniformities of the two universal joints are compensated for. The output speed of the drive shaft (5) on the front axle transmission is then uniform.
