摘要： Jounce bumper (14) for mounting in a vehicle suspension system, said vehicle suspension system comprising a shock absorber with a cylinder and a slidable piston rod (12), said jounce bumper (14) including an elastically compressible bumper portion (24) comprising an axially extending central bore (15) for receiving the piston rod therethrough, a mounting portion (18) positioned at one end of the bumper portion configured for mounting the jounce bumper to a component of the vehicle suspension system, and a bending lip positioned at an opposite end of the bumper portion and configured to generally surround the piston rod, the bending lip comprising a contact edge configured to contact a striker plate of the shock absorber during compression of the shock absorber. The contact edge is configured to contact said striker plate on only part of a closed circumference surrounding the piston rod, at least during initial contact between the bending lip and striker plate.

摘要： Jounce bumper (14) for mounting in a vehicle suspension system comprising a shock absorber with a cylinder and a slidable piston rod (12), the jounce bumper (14) including an elastically compressible bumper portion (24), a mounting portion (18) and an axially extending central bore (15) positionable around the piston rod. The mounting portion (18) comprises a plurality of flexible locking legs (26) configured for insertion through an orifice (32) of a structural element (16) of the suspension system, the flexible locking legs comprising locking protrusions (36) with retaining shoulders (39) configured to engage an edge (33) of the orifice in a locked position. The locking legs have radially inwardly directed cam protrusions (38) configured to be engaged by the piston rod and are movable from an intermediate position after insertion through the structural element orifice to a locked position after insertion of the piston rod through the jounce bumper central bore.

摘要： Provided herein is a jounce bumper (18) for mounting in a vehicle suspension system (2) comprising a shock absorber (6), the jounce bumper (18) having a central bore (20) extending in an axial direction (A). The jounce bumper (18) comprises an elastically compressible bumper portion (24) comprising a plurality of convolutes stacked in an axial direction (A) of the jounce bumper (18), each convolute comprising a crest (26) and a root (28). A cross-section of the compressible portion (24) perpendicular to the axial direction (A) is non-circular, the non-circular shape being configured to provide a variable compression resistance in relation to an axial compression displacement (Cd) of the jounce bumper (18).
