A mounting system for the elastic mounting of a strut or a vibration damper on a vehicle body includes a unit insertable into a receiving cup and a fixing device. The unit includes a mounting unit and a piston rod of a strut or vibration damper. In embodiments, the mounting unit has an elastomer mount for mounting the piston rod; the elastomer mount has a core for receiving the piston rod and an elastomer body, and a ring element that is a separate part or is non-positively, positively and/or materially connected to the body; the unit and fixing device may be inserted into the receiving cup from a side facing away from the body; the fixing device engages behind an undercut formed on the receiving cup; the ring element is supported on the fixing device; and/or the elastomer body is prestressed and presses the ring element against the fixing device.

An air suspension assembly comprises a top and a bottom disposed on a center axis and spaced apart from one another. A bellows of an elastomeric material extends between a first end secured to the top and a second end secured to the bottom defining a chamber. The chamber extends between the top, the bottom, and the bellows for containing pressurized air, whereby a pressure of the pressurized air is controlled based on a force applied. The bellows has an interior surface and an exterior surface and including a plurality of convolutes extending between the first end and the second end. Each convolute of the plurality of convolutes includes a pair of outer lobes and an inner lobe with each outer lobe of the pair of outer lobes having an outer lobe thickness extending between the interior surface and the exterior surface of the bellows.

A strut assembly for a vehicle may include an insulator part connected to a vehicle body, a piston rod coupled to the insulator part, a damper cylinder coupled with the piston rod and having an operating fluid accommodated therein, a strike cap coupled to the upper portion of the damper cylinder, and a sliding part formed on the side surface of the strike cap. In the strut assembly, a dust cover is coupled to the sliding part. In addition, the sliding part includes one or more side surface holes formed on the side surface of the strike cap, a sliding protrusion coupled with the dust cover and mounted in each of the side surface holes, and a guide part formed in each of the side surface holes for restraining the sliding protrusion.

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.

An air spring assembly includes bellow with an outer ring disposed on an outer surface of the bellow. The outer ring containing an embedded cord for constraining a portion of the bellow to establish a “B” shaped fold in an inflated bellow.

The present invention is to provide a bound stopper, which has high mechanical strength, is excellent in durability against fatigue breaking, settling or the like when a heavy load is repeatedly received, and is easy to be produced, in which the bound stopper comprises a polyurethane foam obtained from a polyurethane foam composition containing an isocyanate component and a blowing agent, and the isocyanate component contains a urethane prepolymer having an isocyanate group, the urethane prepolymer being obtained from a polyol component, a polyrotaxane containing a cyclic molecule having an active hydrogen group as a constituent, and an isocyanate.

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 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 strut assembly for a vehicle may include an insulator part connected to a vehicle body, a piston rod coupled to the insulator part, a damper cylinder coupled with the piston rod and having an operating fluid accommodated therein, a strike cap coupled to the upper portion of the damper cylinder, and a sliding part formed on the side surface of the strike cap. In the strut assembly, a dust cover is coupled to the sliding part. In addition, the sliding part includes one or more side surface holes formed on the side surface of the strike cap, a sliding protrusion coupled with the dust cover and mounted in each of the side surface holes, and a guide part formed in each of the side surface holes for restraining the sliding protrusion.

Suspension bumper for the suspension of a motor vehicle, comprising a molded part made of elastomer being essentially symmetrical in revolution about a main axis of compression, this bumper comprising one end forming a crown comprising bearing faces (48) designed to receive pressure from a moving part, the end crown comprising protuberances (58, 60) that are separated from one another by notches (54) distributed over the perimeter of this crown, these bosses having bearing faces (48) arranged at various heights.
