Abstract: A suspension stop for a suspension strut of a vehicle equipped with a coil spring (10) comprises a rigid thrust bearing (24) equipped with a lower metal washer (28) rotating with respect to an upper metal washer (26), a synthetic material support part (38) designed to transmit the forces exerted by the spring to the lower washer and a cover (22) covering the upper washer and delimiting together with the support part a housing (54) for the bearing. The cover is equipped with a skirt (22) delimiting with the peripheral area of the support part an annular labyrinth (60), arranged radially outside the housing and connecting the housing to the outside, with the annular labyrinth successively comprising, from the housing towards the outside, an initial annular head loss of radial play P1, a second annular head loss of axial play P2, followed by a third annular head loss of radial play P3.

Abstract: A Macpherson strut of a vehicle is equipped with a coil spring (10) and a telescopic damper, and a bump stop. The stop comprises a strut bearing (24), an upper support element (18) for transmitting the forces of the telescopic damper and of the bearing to a superstructure of the vehicle, a lower support element (38) made of synthetic material for transmitting to the lower washer the forces exerted by the spring, a cover (22) protecting the bearing and disposed between the upper washer and the upper support element, along with a vibration filtration block (32, 60) of the spring. The bearing is equipped with a lower metal washer (28) rotating in relation to an upper metal washer (26). The cover (22) is disposed between the upper washer and the upper support element and delimits with the lower support element a housing for the bearing. The filtration block is disposed between the upper washer and the cover or built into the cover.
