Suspension system of a vehicle and a shock absorber assembly of the suspension system, the shock absorber assembly includes a top mount and a jounce bumper. The jounce bumper includes a main body made of an elastic material, such as a foam elastomer or rubber and a fixing element made of a second harder material. The fixing element has a wall portion that extends around the outermost upper part of the main body and at least one elastic retaining area cooperating with a respective protuberance arranged in the top mount to fix the jounce bumper to the top mount. Between the outermost upper part of the main body and the fixing element there is a gap that enables the main body to expand radially also in the area covered by the wall portion of the fixing element when the main body is compressed during use.

A strut mount includes an inner member, an outer member, and a body rubber. A stopper rubber which protrudes outward in an axial direction is disposed on the body rubber. The outer member includes a supporting portion which covers the stopper rubber from outside thereof in the axial direction. The stopper rubber includes a pedestal protrusion portion which protrudes outward in the axial direction from the inner member and a tip protrusion portion which protrudes outward in the axial direction from the pedestal protrusion portion, contacts the supporting portion, and has an elasticity in the axial direction lower than that of the pedestal protrusion portion. The pedestal protrusion portion and the tip protrusion portion taper outward in the axial direction.

A bearing structure component for a vehicle bearing, having at least one through-opening for receiving a connecting element or a bearing which is made of foamed synthetic material, and the foamed synthetic material forms an integral foam structure. In an embodiment, at least one first local section of the integral foam structure has a wall thickness of greater than 4 mm.

A damper includes a damper tube (a pressure tube or a reserve tube for a mono-tube or a double tube damper respectively) including a first end and a second end opposite to the first end. The damper includes a base member. The base member includes a cup portion at least partially enclosing the first end of the damper tube, and a sleeve portion extending from and integral with the cup portion. The sleeve portion surrounds a length of the damper tube. The sleeve portion is attached to the damper tube. Further, the damper includes a knuckle engaged with the sleeve portion such that the sleeve portion is disposed between the knuckle and the damper tube.

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.

A strut assembly includes a piston rod of a shock absorber, an upper support of the shock absorber, a bearing, a spring and a buffer block, which are coaxially arranged. The upper support of the shock absorber has a first through hole, the bearing has a second through hole, and a portion of the upper support of the shock absorber is arranged in the second through hole, the buffer block has a third through hole, and one end of the piston rod of the shock absorber is located in the first through hole, the other end of the piston rod of the shock absorber passes through the third through hole, the buffer block is connected with the upper support of the shock absorber, the spring is sleeved around the piston rod of the shock absorber, and the spring is connected with the bearing. The present disclosure further provides a 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.

A spring aid assembly for a vehicle suspension system. The spring aid assembly includes: a housing having a generally cylindrical cavity formed therein, a damper including a rod extending through a cap, and a spring aid having a proximal end retained within the cavity of the housing, a distal end extending in an axial direction away from the housing, and an outer circumferential groove formed therein. The cavity in the housing is bounded by a generally cylindrical inner peripheral wall that has a plurality of axially and radially extending projections extending therefrom. A ring is positioned in the outer circumferential groove of the spring aid. The ring provides a positive stop to the spring aid assembly and prevents the cap of the damper from coming into direct contact with the housing during full compression of the damper.

A suspension device has an upper shell having a stepped section around an inner circumferential surface; a lower shell; a ball screw shaft rotatably supported by the upper shell; a bearing unit arranged between a part of the ball screw shaft and the upper shell, and having an outer side part in a radial direction including a side surface that comes in contact with a side surface on the other side in the axial direction of the stepped section; a ball nut screwed on the ball screw shaft; an inner tube joined to the lower shell and the ball nut; an electric motor; and a coil spring, and a circumscribed circle diameter of the ball nut and the inner tube is less than an inner diameter dimension of the stepped section.

A damper absorbs energy generated between a first component and a second component. The second component is spaced from and moveable toward the first component along a jounce axis. The damper includes a body having a ring-shaped configuration. The body also includes a first edge for engaging the first component and a second edge for engaging the second component. The second edge is spaced from the first edge. The body defines a plurality of holes spaced about the body. The plurality of holes are configured to allow the damper to compress axially for energy as one of the first and second components move along the jounce axis.
