Abstract

A wheel bearing arrangement for a vehicle, having rotatable and statically fixed components, and at least two rolling body bearings arranged radially between the rotatable and statically fixed components for rotatably mounting the rotatable component. The at least two rolling body bearings have in each case an inner ring, an outer ring, and a rolling body row arranged therebetween. A spacer sleeve is arranged at end sides of the respective inner rings for axially securing the two inner rings. A respective securing ring is arranged fixedly on the respective inner rings so as to rotate therewith. The securing rings each have a substantially axially configured lug with a respective radial embossment arranged in a respective groove configured on an outer circumferential face of the spacer sleeve, in order to connect the respective inner rings axially to the spacer sleeve via the respective securing rings.

First claim

The invention claimed is:

1. A wheel bearing arrangement for a vehicle, comprising a rotatable component and a statically fixed component, and at least two rolling body bearings arranged radially between the rotatable component and the statically fixed component for rotatably mounting the rotatable component;
the at least two rolling body bearings each including: an inner ring, an outer ring, and a rolling body row arranged therebetween;
a spacer sleeve arranged between end sides of the respective inner rings for axially securing the two inner rings, the spacer sleeve including grooves located on an outer circumferential face thereof;
securing rings, one of which is arranged fixedly on each of the respective inner rings so as to rotate therewith, the securing rings each including a substantially axially configured lug with a respective radial embossment, the radial embossment being arranged in a respective one of the grooves located on the outer circumferential face of the spacer sleeve, in order to connect each of the respective inner rings axially to the spacer sleeve via the respective securing ring.

2. The wheel bearing arrangement as claimed in claim 1 , wherein the securing rings each include respective first and second limbs, each of the first limbs being arranged fixedly on a respective outer circumferential face of the respective inner ring so as to rotate therewith, and each of the second limb coming into contact with an end side of a respective one of the outer rings.

3. The wheel bearing arrangement as claimed in claim 1 , wherein the securing rings each include respective first and second limbs, and wherein at least one structure for fixedly arranging the respective securing ring on the respective inner ring so as to rotate therewith is configured radially between the respective first limb and the respective inner ring.

4. The wheel bearing arrangement as claimed in claim 3 , wherein the structure forms a positively locking connection between the respective first limb and the respective inner ring.

5. The wheel bearing arrangement as claimed in claim 4 , wherein the positively locking connection is formed of elevations and depressions.

6. The wheel bearing arrangement as claimed in claim 1 , wherein the securing rings are manufactured from a polymer material.

7. The wheel bearing arrangement as claimed in claim 1 , wherein the respective substantially axially configured lug with the respective radial embossment is configured to run around on an end side of the respective securing ring.

8. The wheel bearing arrangement as claimed in claim 1 , wherein the grooves on the spacer sleeve each have a complementary configuration to the respective radial embossments.

9. The wheel bearing arrangement as claimed in claim 1 , wherein the securing rings each include respective first and second limbs, and wherein each of the first limbs contacts a respective one of the inner rings and each of the second limbs contacts a respective one of the outer rings.

10. The wheel bearing arrangement as claimed in claim 9 , wherein the securing rings each include respective third limbs arranged between the respective first and second limbs.

11. A wheel bearing arrangement for a vehicle, comprising a rotatable component and a statically fixed component, and at least two rolling body bearings arranged radially between the rotatable component and the statically fixed component for rotatably mounting the rotatable component;
the at least two rolling body bearings each including: an inner ring, an outer ring, and a rolling body row arranged therebetween;
a spacer sleeve arranged between end sides of the respective inner rings for axially securing the two inner rings, the spacer sleeve including grooves located on an outer circumferential face thereof;
securing rings, one of which is arranged fixedly on each of the respective inner rings so as to rotate therewith, the securing rings each including a substantially axially configured lug with a respective radial embossment, the radial embossment being arranged in a respective one of the grooves located on the outer circumferential face of the spacer sleeve, in order to connect each of the respective inner rings axially to the spacer sleeve via the respective securing ring,
wherein the securing rings each include a respective first, second, and third limb, a respective lubricant reservoir for receiving a lubricant being configured at least between the second and the third limb on each of the securing rings.
