Wheel Bearing/constant velocity joint unit
First Claim
1. A wheel bearing/constant velocity joint unit with a constant velocity joint, a double row bearing (2) provided with at least one inner bearing ring (12) separate from a wheel hub (1) and said inner bearing ring is axially held or tensioned by a formed collar (14) on the wheel hub (1), wherein the improvement comprises that said collar extends radially outward at least partially coextensive with and in contact with said inner bearing ring, spur or helical teeth (15) are formed into the formed collar (14) of the wheel hub (1) in the region at least partially coextensive with the inner bearing ring (12), and said spur or helical teeth are directly and non-rotatingly connectable to one joint component (4) of said constant velocity joint.

Abstract
The invention relates to a wheel bearing/constant velocity joint unit having a double row bearing 2 which has been provided with at least one inner bearing ring 12 which is separate from the wheel hub 1. The wheel hub and the outer part of the constant velocity joint are form-fittingly and non-rotatingly connected to each other by spur teeth. The spur teeth at the wheel hub are preferably produced by orbital pressing or orbital forging, and while the forming process takes place a collar is produced at the wheel hub which serves for axially tensioning the inner bearing rings, at least the one of the joint end.

1. A wheel bearing/constant velocity joint unit with a constant velocity joint, a double row bearing (2) provided with at least one inner bearing ring (12) separate from a wheel hub (1) and said inner bearing ring is axially held or tensioned by a formed collar (14) on the wheel hub (1), wherein the improvement comprises that said collar extends radially outward at least partially coextensive with and in contact with said inner bearing ring, spur or helical teeth (15) are formed into the formed collar (14) of the wheel hub (1) in the region at least partially coextensive with the inner bearing ring (12), and said spur or helical teeth are directly and non-rotatingly connectable to one joint component (4) of said constant velocity joint.
- 2. A wheel bearing/constant velocity joint unit with a constant velocity joint, a double row bearing (2) provided with at least one inner bearing ring (12) separate from a wheel hub (1) and said inner bearing ring is axially held or tensioned by a formed collar (14) on the wheel hub (1), wherein the improvement comprises that said collar extends radially outwardly at least partially coextensive with and in contact with said inner bearing ring, helical or spur teeth (153) provided on an annular projection (18) extending radially outwardly from the inner bearing ring, said helical or spur teeth are directly and non-rotatingly connectable to one joint component of said constant velocity joint, with the inner bearing ring (12) having preformed engaging means engaged by the formed collar (14) in a form-fitting way.
- 3. A wheel bearing/constant velocity joint unit with a constant velocity joint, a double row bearing (2) provided with at least one inner bearing ring (12) separate from a wheel hub (1) and said inner bearing ring is axially held or tensioned by a formed collar (14) on the wheel hub (1), wherein the improvement comprises that said collar extends radially outwardly at least partially coextensive with said inner bearing ring, helical or spur teeth (15) provided on an intermediate ring (20) which is separate from the inner bearing ring (12) and from the wheel hub (1) and extends radially outwardly from said hub at least partially coextensive with the inner bearing ring (12), the helical or spur teeth (15) being directly and non-rotatingly connectable to one joint component of said constant velocity joint, and the intermediate ring (20) having preformed engaging means (21) engaged by the collar in a form-fitting way.
