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.
