A suspension structure for vehicle (a suspension arm for vehicle) is formed of a first plate and a second plate, and includes a mounting part for mounting a component (a collar or a bush). The first plate is partially open toward a first flat plate part so that a first mounting surface can be formed by stamping in a state of a single unit where a first flat plate part is bent. The second plate is also partially open toward a second flat plate part. The mounting part is configured by facing the first flat plate part of the first plate and the second flat plate part of the second plate each other at a distance, and disposing the first mounting surface and a second mounting surface at a distance.

A vibration damper for a motor vehicle may comprise a damper outer tube, a damper inner tube having a lateral surface of the damper inner tube and arranged coaxially in the damper outer tube, a separating plate arranged coaxially in a region of the lateral surface of the damper inner tube, and a sealing element arranged coaxially circumferentially on the damper inner tube on the separating plate. In a region of the separating plate arranged coaxially on the lateral surface of the damper inner tube, a groove for the separating plate may be formed on the lateral surface of the damper inner tube. The separating plate may be arranged in the groove, and the connection between the groove and the separating plate may be press fit, at least in the radial direction.

A dual compound bushing includes a tube having a first end, a second end, and an intermediate portion extending therebetween. A first elastomeric member having a first durometer value is arranged on the intermediate portion. A second elastomeric member having a second durometer value that is distinct from the first durometer value is arranged at the first end. A ferrule is mounted to the tube at the first end. The second elastomeric member being arranged between the ferrule and the first elastomeric member.

An air spring includes a composite bumper, a composite piston, a flexible bellow and an upper end cap member. The composite piston has a first end which includes a plurality of rigid portions and a plurality of adjacently positioned cantilever snap joints for receiving and securing the composite bumper. The composite bumper includes an inner wall having a surface shape for securely engaging the plurality of rigid portions and the plurality of cantilever snap joints. The first end of the composite piston further includes a piston housing surface upon which an outer surface of the composite bumper nests against. The flexible bellow is sealingly attached to the composite piston and the upper end cap member. The flexible bellow, the upper end cap member, and the composite piston together form a fluid tight chamber, and the composite bumper is contained within the fluid tight chamber.

The ball joint assembly includes a housing with an inner wall that surrounds an axially extending open bore. A ball portion of a ball stud is received in the open bore of the housing, and a shank portion of the ball stud projects out of the open bore. A pair of bearings are disposed in the inner bore of the housing and are interposed between the ball portion and the inner wall. Each bearing has a curved bearing surface which slidably contacts the ball portion for allowing the ball stud and the housing articulate relative before use. Each bearing also has an outer surface that slidably contacts the inner wall. A pair of biasing elements bias the bearings in opposite directions against the ball portion of the ball stud such that the ball stud is movable relative to the housing in the axial direction before use of the assembly.

A ball stud (21) for a ball joint (20) having an annular body (22) pressed onto the ball stud (21). The annular body (22) is held fast to the ball stud (21) by at least one circumferential securing element to prevent loosening, that acts between the ball stud (21) and the annular body (22) and is in the form of a deformation edge (23). The at least one deformation edge (23) is formed integrally with the ball stud (14). A ball joint (20) that has a housing (36) in which a ball stud (21) is held.

End member assemblies having a longitudinal axis are dimensioned for securement to a flexible spring member. The end member assemblies include a first end member with a first surface portion and a plurality of projections disposed in peripherally-spaced relation to one another about the longitudinal axis. A second end member includes a plurality of grooves dimensioned to receive one of projections. Gas spring and damper assemblies include a damper assembly and a gas spring assembly that includes an end member assembly as well as an end member assembly with a flexible spring member secured between the end member assemblies. A suspension system including one or more gas spring and damper assemblies is also included.

The present invention relates to a damper assembly for a hydraulic shock absorber, the damper assembly comprising a damping cylinder and a piston assembly being arranged in said damping cylinder and axially movable with respect thereto. The piston assembly comprises a piston having an outer cylindrical surface) comprising an annular groove; a friction element arranged in said annular groove of said piston; and a resilient element arranged inside said annular groove between an inner wall of said annular groove and said friction element and arranged to force the friction element towards an inner surface of the damping cylinder, wherein said friction element is made from metal and comprises a coating made of a low friction material. The damper assembly provides improved durability of the damping capacity.

A vehicle suspension bushing assembly including an inner sleeve, a bearing, an intermediate sleeve, an outer sleeve, and a bushing. The inner sleeve extends longitudinally between first and second inner sleeve ends. The bearing extends annularly about the inner sleeve, the intermediate sleeve extends annularly about the bearing, and the outer sleeve extends annularly about the intermediate sleeve. The bushing is positioned radially between the outer sleeve and the intermediate sleeve. Axial retainers extend annularly about the first and second inner sleeve ends. The axial retainers are longitudinally moveable relative to the inner sleeve. The axial retainers have a preload feature including a flange segment that is resilient and deflects from an unbiased position when the axial retainers are in an uncompressed position to a biased position when the axial retainers are in a compressed position to apply a longitudinal preload force to the intermediate sleeve.

The disclosure relates to a control arm for a wheel suspension system in a vehicle, including a sleeve-shaped aperture for the receiving of a bearing is formed in an integral control arm body, wherein the integral control arm body comprises a first side wall and a second side wall that is facing the first side wall. The sleeve-shaped aperture penetrates the first side wall and the second side wall. The sleeve-shaped aperture is formed sleeve-shaped with a first circumferential sleeve rim and a second circumferential sleeve rim. The first sleeve rim is formed by an outwardly shaped section of the first side wall that defines the sleeve-shaped aperture.
