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.
A rotationally fixed connection comprising:
A method of producing a hub for connection with a shaft having outer shaft teeth with a stepped end formed at the end of the outer shaft teeth, the method comprising providing a hub including a through bore, said hub having hub teeth extending within said through bore such that, when connected with the shaft, the stepped end of the outer shaft teeth are inside the hub;
A constant velocity joint and shaft connection comprising:
