Abstract:
1. A suspension thrust bearing including at least one rolling bearing forming an axial thrust bearing disposed on a lower cap, the lower cap comprising a support configured to receive the at least one rolling bearing and a body disposed on the support, the body comprising: an annular rolling bearing portion for a spring, a tubular portion including a bore in which a shock absorber bump stop is inserted, and an axial contact surface which extends in the axial direction and is defined on a lower portion of the bore of the tubular portion against which the shock absorber bump stop when deformed exerts a radial force, the tubular portion including a reinforcing insert located at the level of the axial contact surface, wherein the tubular portion of the lower cap further includes in its bore an annular bead directed toward an interior side of the suspension thrust bearing, the interior side corresponding to a main axis of the suspension thrust bearing, the bead including a portion of the reinforcing insert therein enabling its reinforcement in the event of a force exerted by the shock absorber bump stop and cooperating and interfering with an annular rib of the shock absorber bump stop such that the annular bead maintains the shock absorber bump stop such that an upper surface of the shock absorber bump stop is in constant contact with the support, wherein the support is comprised of metal.
