Drive shafts and universal joints

Drive shafts and universal joints


An intermediate shaft with a high torsional rigidity emerges from the right-hand side of the differential and is journalled in an extra support bearing which is secured to the engine body. In this way the drive shafts can be made identical and will have the same angle in relation to the wheels. The advantage with this solution is that the car's directional stability remains totally intact, even during very hard acceleration.

On the left-hand side the inner universal joint is connected to the differential by a quick coupling. In a corresponding way the right inner universal joint is connected to the intermediate shaft. The universal joints are filled with grease and protected from dirt and moisture by a rubber bellows.

There are two variations of the inner universal joint.



1. Tripode type

which consists of a tripod housing and a tripod. The tripod consists of three rollers in needle bearings and can move axially in the tripod housing.

2. The Rzeppa type

in which the torque is transferred via six balls which run in axial grooves. In this variant of the Rzeppa universal joint the joint can move axially.
