Drive shaft

Lightweight construction is the key to the optimum drive shaft
The drive shaft is the dynamic connection between the transmission and the drive wheels. Being part of the drive train, it is here that the torque is transferred from the transmission to the wheels.

The potential of cold forming for drive shafts
Cold forming has the potential to unlock the evolution of shaft cross-sections. Whether the aim is weight savings, increased strength or a reduction in the number of components through functional integration or high spline classes, none of these objectives are at odds with cold forming; rather they all become integrated components of a single process. Having a larger outer diameter at the same time as a smaller wall thickness increases the torsional strength and improves the vibration behaviour compared to a solid shaft while also reducing the weight of the hollow drive shaft.
