Abstract
A suspension thrust bearing device for use with a suspension spring in an automotive suspension strut of a vehicle. The device provides a bearing having upper and lower annular bearing members in relative rotation, lower bearing member having a lower cup having at least one protruding indexation element. The device also provides a damping element made of resilient material and interposed between the lower cup and the suspension spring. The indexation element is made of a different material than that of the lower cup, the lower cup being made of a rigid plastic material and the indexation element being made of a resilient material.

A suspension thrust bearing device for use with a suspension spring in an automotive suspension strut of a vehicle, the device comprising:
- a bearing having upper and lower annular bearing members in relative rotation, the upper bearing member having an upper cup, the lower bearing member having a lower cup, the lower cup having a radial surface located axially farthest from the upper cup and being provided with at least one protruding indexation element protruding downwardly from the radial surface, and
- a damping element made of resilient material and interposed between the lower cup and the suspension spring, wherein
- the at least one protruding indexation element extends only along a portion of a circumference of the lower cup, wherein
- the indexation element is made of a different material than that of the lower cup, and wherein
- the lower cup being made of a rigid plastic material and the indexation element being made of a resilient material, the indexation element being deformable at a lower pressure than the lower cup.
