Abstract
A wheel hub/constant velocity joint unit has a two-row wheel bearing with a common outer bearing race (16). A joint member (4) with an end sleeve (5) is slid on to the wheel hub (1) and connected thereto while the wheel bearing is in a pretensioned condition. The connection of the hub (1) and joint member (4) is effected by a weld (23, 24, 29) located in the region of a plug-in connection between the externally positioned end sleeve (5) of the joint member (4) and the internally positioned wheel hub (1).
Claims17
A wheel hub/constant velocity joint assembly comprising:
- a wheel hub having an elongated cylindrical sleeve portion;
- a two-row wheel bearing including a common outer bearing ring, two rows of roller means and at least one inner bearing ring separate from the wheel hub, said two row wheel bearing positioned on said elongated cylindrical sleeve portion of said wheel hub;
- a joint member of a constant velocity joint having an end sleeve circumferentially positioned about a portion of said elongated cylindrical sleeve portion on said wheel hub adjacent an axially inner bearing ring for providing a tension force in said two row wheel bearing;
- aperture means for receiving a weld, said means circumferentially distributed about said joint member end sleeve;
- a weld affixing said joint member to said hub while the two row wheel bearing is in a pretensioned condition;
- and
- said weld being generated substantially radially about said sleeve in said weld receiving means and penetrating the sleeve of the joint member and penetrating into the wheel hub.
A wheel hub/constant velocity joint assembly comprising:
- a wheel hub with an overall bowl shape and having an elongated cylindrical sleeve portion and a terminal bottom closing off the hub;
- a two-row wheel bearing including a common outer bearing ring, two rows of roller means and at least one inner bearing ring separate from the wheel hub, said two row wheel bearing positioned on said elongated cylindrical sleeve portion of said wheel hub;
- a joint member of a constant velocity joint having an end sleeve circumferentially positioned on said wheel hub about a portion of said elongated cylindrical sleeve portion and said bottom adjacent an axially inner bearing ring for providing a tension force in said two row wheel bearing;
- a weld affixing said joint member to said hub while the two row wheel bearing is in a pretensioned condition;
- and
- said weld being generated substantially radially about said sleeve, adjacent said terminal bottom and penetrating the sleeve of the joint member and penetrating into the wheel hub.
