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 unit (1) for a suspension strut (2) of a motor vehicle (3), has at least the following components: a guide ring (4) having a guide axis (5) for a wheel spring (6); a cap (7) with a damper holder (8) for a damper block (9); a bumpstop holder (10) for a bumpstop (11); an axial bearing (12) with a bearing pitch circle (13) for supporting the guide ring (4) on the cap (7) and for low-friction rotation about the guide axis (5) relative to the cap (7). The bumpstop holder (10) is formed integrally by the cap (7).

A spring element, in particular a jounce bumper, for a vehicle shock absorber contains a longitudinal axis, a base body extending along the longitudinal axis, and an end portion configured for contact against a damper cap of the vehicle shock absorber. 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 at least three projections that are spaced apart from one another in a circumferential direction, and protrude from the base body in the direction of the longitudinal axis. Each of the projections has a distinct length in the direction of the longitudinal axis, and the projections are arranged along the circumference of the end portion such that the lengths of the projections increase monotonously in the circumferential direction.

A vehicle strut assembly includes a boot and a coil spring. The boot has a vertical wall, a spring receiving portion and a centering portion projecting from the vertical wall. The coil spring has an end section, a transition section and a main section, the end section being fitted to the spring receiving portion encircling at least a portion of the vertical wall and defining a first radially inner diameter. The transition section has an increasing inner diameter extending from the end section to the main section. The main section defines a second radially inner diameter greater than the first radially inner diameter. The centering portion is positioned to contact a radially inner surface of the transition section of the coil spring restricting movement of the end section of the coil spring relative to the spring receiving portion of the boot.

A suspension thrust bearing device for use with a suspension spring in an automotive suspension strut of a vehicle. The device provides a bearing having upper and lower annular bearing members in relative rotation, and a damping element made of resilient material and interposed between the lower annular bearing member and the suspension spring. The damping element including at least one deflecting flange for reducing any ingress of water and other pollutants between the upper and lower annular bearing members. The damping element is provided with an annular groove open axially towards the suspension spring, the annular groove radially defining a spring support surface on an inner side, and the deflecting flange on an outer side. The deflecting flange has a frustoconical shape directed axially towards the suspension spring.

A strut mount cap is provided on an upper surface of a strut mount, and is configured to close a hole housing a fastening component for the strut mount and a shock absorber. The strut mount cap includes a cap body configured to close the hole, an annular water stop lip provided on an outer periphery of the cap body and in elastic contact with the upper surface of the strut mount to prevent water from entering the hole, a press-fit tube provided on a back side of the cap body and held on an inner peripheral surface of the hole by being press-fitted into the hole, and a check valve configured to open the hole when an internal pressure in the hole is equal to or higher than a preset pressure, and close the hole when the internal pressure is lower than the preset pressure.

A vehicle suspension system may include a first suspension assembly operably coupling a first wheel to a chassis of a vehicle, a second suspension assembly operably coupling a second wheel to the chassis where the first and second wheels form a pair of front wheels, a third suspension assembly operably coupling a third wheel to the chassis, a fourth suspension assembly operably coupling a fourth wheel to the chassis where the third and fourth wheels forming a first pair of rear wheels, and a payload extension kit that is attachable to the chassis non-permanently. The payload extension kit may include a fifth suspension assembly operably coupling a fifth wheel to a sub-frame extension of the payload extension kit, and a sixth suspension assembly operably coupling a sixth wheel to the sub-frame extension, where the fifth and sixth wheels form a second pair of rear wheels.

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 hydraulic ride height actuator system for providing variation of a ride height at a front end of a vehicle is provided includes a strut and an actuator including a piston and a housing axially movable with respect to the piston. The housing is fastened to an upper end of the strut. The piston and the housing define a hydraulic chamber. An increase in a volume of the hydraulic chamber forces the housing upward to vary the ride height.

A shock absorber arrangement for a vehicle suspension contains a shock absorber having a damper cap and a piston rod, and a supplementary spring which is arranged on the piston rod opposite the shock absorber and has an outer surface facing the damper cap and an inner surface facing the piston rod, and is configured for damping the movement of the shock absorber in the direction of the piston rod on contact with the damper cap. The outer surface and/or the inner surface is at least partially coated with a lubricant.
