Abstract
A suspension thrust bearing provides a bearing with annular upper part and annular lower part. The lower part provides an axial hub, an outwardly projected radial flange extending from the axial hub, and a curved connecting portion between the axial hub and radial flange. The lower part provides an exterior support surface that axially supports an upper end of a suspension spring by a damping device made from resilient material. The exterior support surface provides at least one longitudinal groove, the damping device including an interior surface contacting the exterior support surface and including a complementary shape to mate with the groove. The groove extends along the connecting portion, disposed in a recessed portion between two longitudinal side walls, a first groove end on or directed towards the hub, and a second groove end on or directed towards the flange, the second groove end being a transverse wall.
