Abstract
An insertable unit for a wheel bearing has an integrated constant velocity universal joint, which is axially insertable into the wheel carrier from the outside and which permits easy dismantling and re-assembly. The outer joint part at the wheel end can be inserted through the through-bore of the wheel carrier. The outer bearing ring is inserted into the through-bore and is secured against axial displacement. The inner diameter of the two-part inner bearing ring is smaller than the outer diameter of the outer joint part. The outer joint part and the wheel hub are welded to one another in the region of the axially inner end of the two-part inner bearing ring, with the outer joint part being supported on the inner bearing ring by a planar face.
Claims14
An insertable unit for a bearing assembly of a driving axle, said driving axle including a wheel carrier defining a through-bore, said insertable unit comprising:
- a wheel hub;
- a double-row bearing mounted on said wheel hub, said double-row bearing having an inner bearing ring defining an inner diameter and an outer bearing ring defining an outer diameter, said outer bearing ring for securing within said through-bore of said wheel carrier;
- and
- an outer constant velocity universal joint having an outer joint part defining an outer diameter and an inner joint part, said outer diameter of said outer joint part being larger than said inner diameter of said inner bearing ring, and said outer diameter of said outer joint part being substantially similar in size to the outer diameter of said outer bearing ring and a diameter of said through-bore such that said through-bore diameter enables insertion of said outer constant velocity universal joint, via a clearance fit, through said through-bore and said outer bearing ring is press fit relative to said through-bore, said outer joint part of said outer joint being welded to said wheel hub adjacent one end of said inner bearing ring and supported on said inner bearing ring by a planar face.
An insertable unit for a bearing assembly of a driving axle, said driving axle including a wheel carrier defining a through-bore, said insertable unit comprising:
- a wheel hub;
