Abstract
A suspension thrust bearing device for use with a suspension spring in an automotive suspension strut of a vehicle. The device includes an upper annular bearing member and a lower annular bearing member in relative rotation. The lower annular bearing member having a body provided with an embedded stiffening insert. The device further provides a damping element made of resilient material and interposed between the lower annular bearing member and the suspension spring. A radial flange of the damping element prevents separation from the lower side of the radial flange of the lower cap.

A suspension thrust bearing device for use with a suspension spring in an automotive suspension strut of a vehicle, the suspension thrust bearing device comprising:
- a bearing having an upper annular bearing member and a lower annular bearing member in relative rotation, the lower annular bearing member having a body provided with an embedded stiffening insert, the embedded stiffening insert having a radially outermost end, and
- a damping element made of resilient material and interposed between the lower annular bearing member and the suspension spring, wherein
- the body of the lower annular bearing member comprises at least one body through hole, and the embedded stiffening insert also comprises at least one insert through hole provided within the body through hole, the insert through hole being smaller in diameter than the body through hole, and the damping element further comprises at least one extending pin arranged within the body and insert through holes, the pin having a circumferential groove wherein the insert is fitted, and wherein
- all of the damping element which extends through the body through hole and the insert through hole has a smaller radially outermost diameter than an outer diameter of the radially outermost end of the stiffening element.
A motor vehicle suspension strut comprising:
- a damper rod,
- a suspension spring, and
- a suspension thrust bearing device providing a bearing having an upper annular bearing member and a lower annular bearing member in relative rotation, the lower annular bearing member having a body provided with an embedded stiffening insert, the embedded stiffening insert having a radially outermost end, and
- a damping element made of resilient material and interposed between the lower annular bearing member and the suspension spring, wherein
- the body of the lower annular bearing member comprises at least one body through hole, and the embedded stiffening insert also comprises at least one insert through hole provided within the body through hole, the insert through hole being smaller in diameter than the body through hole, and the damping element further comprises at least one extending pin arranged within the body and insert through holes, the pin having a circumferential groove wherein the insert is fitted, and wherein
- all of the damping element which extends through the body through hole and the insert through hole has a smaller radially outermost diameter than an outer diameter of the radially outermost end of the stiffening element.
