摘要： A jounce bumper assembly can be used in a suspension system for an automotive vehicle. The assembly can contain a jounce bumper having a longitudinal axis, a bottom portion, and a tip portion spaced apart from the bottom portion in the axial direction, where the jounce bumper is resiliently deformable between an uncompressed basic state and an axially compressed state. The assembly can also contain a support member for supporting the jounce bumper, the support member having a wall section which can be arranged around the bottom portion and resiliently deformable with the jounce bumper in the axial and radial direction. The assembly can further contain at least one stiffening element associated to the wall section and configured to locally limit the radial deformation of the support member.

摘要： A shock absorber includes a bearing unit having a bearing and a bearing holding member, and a seal unit having a seal member and a seal holding member. The seal holding member includes a seal accommodating portion being configured to accommodate the seal member, and an insertion hole through which a piston rod is inserted. The seal member is pressed against an outer circumferential surface of the piston rod and the seal accommodating portion by working-fluid pressure in the extension-side chamber. And the bearing is provided such that a first end surface of the bearing facing the seal member matches an aperture plane of a through hole of the bearing holding member or such that the first end surface of the bearing projects out from the aperture plane of the through hole.

摘要： A spring element, in particular a jounce bumper, for a jounce bumper assembly, contains a longitudinal axis, a base body extending along the longitudinal axis, and an end portion configured for being brought into contact with a vehicle part moving relatively to the spring element. The base body is elastically deformable between an uncompressed basic state and a compressed state in which the base body is at least partially compressed in the direction of the longitudinal axis. The end portion contains a circumferential outer surface, and at least one recess in the circumferential outer surface. The recess extends inwards and defines a hollow space in the base body.

摘要： A rebound bumper for a shock absorber includes a first portion formed from a first material having a first spring rate and a second portion coupled to the first portion and formed from a second material having a second spring rate greater than the first spring rate. The first portion and the second portion are configured to fit on a piston rod between a piston and a rod guide assembly of the shock absorber. Also, the rebound bumper exhibits a displacement under load relationship with the first spring rate, the second spring rate, and a third spring rate greater than the first spring rate and less than the second spring rate.

摘要： A damper providing varying damping force is provided. The damper may include a housing and a rotary member rotatably received the housing. The rotary member may rotate within the housing between defined end points of travel to define an angular range of travel of the rotary member. An outermost surface of the rotary member may be spaced inwardly from an inner surface of the housing defined between the end points of travel to define a gap between the outermost surface of the rotary member and the inner surface of the housing throughout the angular range of travel. The gap may vary in dimension depending on a rotational position of the rotary member to provide varying damping rates within the angular range of travel of the rotary member.
