Abstract

A bearing assembly for bearing a steering shaft includes a bearing housing, a bearing, and a damping disk. The housing has two housing sections. The bearing is integrated into the damping disk. The damping disk is positioned so that an inner wall of a first housing section radially supports a circumferential side of the damping disk, and such that a second housing section is axially supported by the damping disk.

First claim

The invention claimed is:

1. A bearing assembly, comprising:
a bearing housing including two housing sections; and
a damping disk positioned in the bearing housing such that an inner wall of a first of the two housing sections radially supports a circumferential side of the damping disk, and such that the damping disk axially supports a second of the two housing sections; the damping disk including a bearing.

2. The bearing assembly as claimed in claim 1 , further comprising: a spring element that axially supports the second of the two housing sections on the damping disk.

3. The bearing assembly as claimed in claim 1 , wherein the damping disk further includes an inner disk and an outer ring, the inner disk composed of a harder material relative to a softer material that composes the outer ring, and the outer ring supported on an inside of the housing.

4. The bearing assembly as claimed in claim 3 , wherein the damping disk is embodied as a two-component disk.

5. The bearing assembly as claimed in claim 3 , further comprising:
a spring element that axially supports the second of the two housing sections on the damping disk, wherein the spring element is supported on the inner disk.

6. The bearing assembly as claimed in claim 1 , wherein the bearing is a floating bearing positioned in the damping disk.

7. The bearing assembly as claimed in claim 1 , further comprising:
a second bearing integrated into the bearing housing at an axial distance from the first bearing.

8. The bearing assembly as claimed in claim 7 , wherein the second bearing is a fixed bearing.

9. The bearing assembly as claimed in claim 7 , further comprising:
a helical gear configured to fixedly connect to a steering shaft or to a shaft section of a steering shaft, the helical gear configured to transmit a torque of a servo unit to the steering shaft or the shaft section, and the helical gear positioned axially between the damping disk and the second bearing.

10. A steering device for a vehicle, comprising:
a steering shaft or a shaft section coupled to a steering shaft
a bearing assembly for bearing the steering shaft or the shaft section, the bearing assembly including:
a bearing housing having two housing sections; and
a damping disk positioned in the bearing housing such that an inner wall of a first of the two housing sections radially supports a circumferential side of the damping disk, and such that the damping disk axially supports a second of the two housing sections; the damping disk including a bearing.

11. The bearing assembly as claimed in claim 1 , wherein the bearing assembly is configured to rotationally bear a steering shaft or a shaft section coupled to a steering shaft of a steering device.
