Abstract

A rotational fixed connection has a shaft whose axial end is provided with outer shaft teeth and a hub whose through-bore is provided with inner teeth. The connection is useful between a driveshaft in the driveline of a motor vehicle and a joint hub of a universal tripod joint or a constant velocity universal ball joint. The joints include the hub, torque transmitting roller elements, and an outer joint part. The outer shaft teeth of the shaft, at a distance from the hub teeth end at the shaft shank end, run out steplessly into the shaft shank. The outer shaft teeth end inside the hub with a stepped end. In the region following the outer shaft teeth, the shaft includes a tooth-free end portion. The tooth-free end portion carries or forms fixing elements which axially securingly rest against a hub end face at the end where the shaft terminates. The inner shaft teeth of the hub, at the end where the shaft terminates, includes a deformed portion which rests axially securingly against the end of the outer shaft teeth and prevents engagement therewith.
