Abstract

A rolling bearing assembly including an intermediate bearing ring is provided. The rolling bearing assembly includes an inner bearing ring including at least one axial end configured to be supported on a first component, and an outer bearing ring including at least one axial end configured to be supported on a second component. The intermediate bearing ring is arranged between the inner bearing ring and the outer bearing ring and includes at least one axial end configured to be supported on a third component. The at least one axial end of the intermediate bearing ring extends in an axial direction past at least one of the at least one axial end of the inner bearing ring or the at least one axial end of the outer bearing ring.

First claim

What is claimed is:

1. A differential assembly including a rolling bearing assembly, the rolling bearing assembly comprising:
an inner bearing ring including at least one axial end configured to be supported on a first component;
an outer bearing ring including at least one axial end configured to be supported on a second component;
an intermediate bearing ring including at least one axial end configured to be supported on a third component, wherein the at least one axial end of the intermediate bearing ring extends in an axial direction past at least one of the at least one axial end of the inner bearing ring or the at least one axial end of the outer bearing ring;
a first row of rolling elements supported between the inner bearing ring and the intermediate bearing ring, the inner bearing ring includes a radially inner race on which the first row of rolling elements run, and the intermediate bearing ring includes a radially outer race on which the first row of rolling elements run; and
a second row of rolling elements supported between the outer bearing ring and the intermediate bearing ring, the outer bearing ring includes a radially outer race on which the second row of rolling elements run, and the intermediate bearing ring includes a radially inner race on which the second row of rolling elements run,
wherein the first component is an output shaft, the second component is a carrier plate, and the third component is a transmission housing.

2. The differential assembly of claim 1 , further comprising a first cage for supporting the first row of rolling elements, and a second cage for supporting the second row of rolling elements.

3. The differential assembly of claim 1 , wherein the radially inner race of the intermediate bearing ring is defined on a first portion of the intermediate bearing ring, and the radially outer race of the intermediate bearing ring is defined on a second portion of the intermediate bearing ring, and the first and second portions of the intermediate bearing ring axially overlap at a transition portion of the intermediate bearing ring.

4. The differential assembly of claim 1 , wherein the at least one axial end of the intermediate bearing ring is fixed to the third component.

5. The differential assembly of claim 4 , wherein the at least one axial end of the intermediate bearing ring is fixed to the third component by a press fit.

6. The differential assembly of claim 4 , wherein the at least one axial end of the intermediate bearing ring is fixed to the third component by welding.

7. The differential assembly of claim 1 , wherein the first and second components are supported via the intermediate bearing ring on the third component.
