Abstract

The invention relates to a suspension thrust bearing unit (1) for use in an automotive suspension assembly having an upper annular cap and a lower annular cap (4) rotatable with respect to the upper annular cap (3), the upper annular cap and the lower annular cap delimiting together an annular chamber that houses a rolling bearing (5). The lower annular cap comprises a subassembly (6) for dampingvibrations and distributing stress and is provided with a lower support surface (82) that axially supports an upper end of a suspension spring. The subassembly includes an annular stiffening cup (7) made from a metal material and mounted to the lower cap, and an annular damping device (8) made from a resilient material and mounted to the stiffening cup. The stiffening cup having at least one protruding portion (73, 74) formed by stamping and that extends towards the damping device, the damping device being locally deformed by the protruding portion and forming a recess (83, 84) to receive theprotruding portion (73, 74).

Description

technical field

[0001] The present invention relates to the field of suspension thrust bearing units, in particular to the field of suspension thrust bearing units of MacPherson type suspensions. Such a suspension thrust bearing unit is equipped with a suspension assembly used in a motor vehicle. Background technique

[0002] In general, a motor vehicle suspension system includes a suspension assembly that supports an axle and wheels. A suspension thrust bearing unit is arranged in an upper portion of the suspension assembly, opposite the wheels and the ground, and between an upper support block attached to the vehicle body and a suspension spring.

[0003] The suspension thrust bearing unit includes at least one rolling bearing.

[0004] The suspension thrust bearing unit is capable of transferring axial forces between the vehicle body and the spring, while allowing relative angular motion between the spring (which moves in rotation) and a fixed support block attached to ...
