Abstract: A suspension strut includes a telescopic damper, a coil spring and a suspension stop. The rotation of the suspension stop is provided by a bearing including at least one single-piece upper washer and a single-piece lower washer, the upper washer forming a planar annular bearing surface for a rod of the telescopic damper. The interface between the coiled spring and the bearing is provided by a single-piece cup including a body forming a peripheral annular zone for housing an upper end of the coiled spring. The single-piece cup includes an anti-wear coating having a thickness of less than 2 mm, overmolded on the body and at least partially covering the peripheral annular zone housing zone in order to be interposed between the body of the single-piece cup and the upper end of the coil spring.

Abstract: A rotary suspension stop for a suspension strut comprises a bearing, a lower support forming a bearing surface for an upper turn of a helical spring and an annular shrink-fitting surface turned radially in a radial reference direction, a cover comprising an annular skirt extending axially facing and at a distance from the shrink-fitting surface and a seal having a body, at least one annular sealing lip in sliding contact against the annular skirt of the cover and at least a first set of one or more elastic first shrink-fit lips projecting toward the shrink-fitting surface and shrunk to the shrink-fitting surface.

Abstract: The invention relates to a bearing cage for a bearing of the type comprising a first ring having a first bearing race, a second ring having a second bearing race, rolling bodies positioned in an annular rolling volume between the first and the second bearing races in such a way as to enable a relative rotation between the first and second rings around a reference axis of the bearing, the cage comprising cells for housing rolling bodies, the cage being characterised in that it comprises an interface for coupling with a maneuvering member, such that when the maneuvering member is engaged with the coupling interface, the bearing cage is capable of being rotationally driven by the maneuvering member in a predetermined direction with respect to the reference axis.

Abstract: The invention relates to a suspension stop with an upper cup and a lower cup arranged to form between them an annular chamber which is delimited laterally by two walls. The chamber having an external section formed between a bearing surface of each wall respectively, the suspension stop having an external sealing element with two complementary bearing surfaces. The external sealing element is mounted to be mobile in the external section between a stable position in which the complementary bearing surfaces are arranged at a distance from the bearing surfaces of the external section and a stressed position by bearing on the external sealing element in which the complementary bearing surfaces are forced against one of the bearing surfaces to ensure the sealing of the external section at the interface thereof.
