Abstract

A wheel bearing arrangement with first rolling elements, which are capable of rolling on a first inner ring, wherein the rolling elements are guided by a first roller bearing cage, and an axial spacer element is provided for spacing apart the first inner ring from a bearing element, wherein the bearing element can in particular be a second inner ring. The intention is to facilitate the complex installation of the individual parts in wheel bearings for utility vehicles. The first rolling element cage forms, together with the axial spacer element, an axial form-fitting connection. The spacer element can be fixed to at least one of the inner rings via the form-fitting connection to the cage prior to tightening the wheel hub, together with the wheel bearing preinstalled thereon.

Claims (13)

1. A wheel bearing arrangement comprising:

first rolling elements rollable on a first inner ring, the first rolling elements being guided through a first rolling bearing cage; and

an axial spacing element for spacing the first inner ring from a bearing element, the first rolling bearing cage forming a positive engagement with the axial spacing element;

wherein the positive engagement is formed by interlocking retaining elements;

wherein one of the interlocking retaining elements is a retaining element of the axial spacing element, the retaining element is an at least partially annular peripheral elevation;

wherein the elevation comprises a lead-in surface;

wherein the elevation yields elastically;

wherein an at least one end piece is movable during elastic loading of the elevation and at a definable elastic loading, the end piece coming to abut against a stopper limiting the elastic loading.

2. The wheel bearing arrangement as recited in claim 1 wherein the axial spacing element is a sleeve.

3. The wheel bearing arrangement as recited in claim 1 wherein one of the interlocking retaining elements is a bearing cage retaining element of the first rolling bearing cage, the bearing cage retaining element being an end piece pointing in a radially inward direction.

4. The wheel bearing arrangement as recited in claim 1 wherein the elastic loading can be defined by a determined amount of taper of the at least one end piece or by a determined length of the at least one end piece.

5. The wheel bearing arrangement as recited in claim 1 wherein the elevation is configured as a hook or a retaining claw.

6. The wheel bearing arrangement as recited in claim 1 wherein the bearing element is a second inner ring on which further rolling elements guided through a second rolling bearing cage roll, the second rolling bearing cage also forming a positive engagement with the axial spacing element.
