A hydropneumatic suspension strut includes a piston-cylinder unit with a first gas spring and a second carrying spring. The gas spring and the carrying spring are connected in parallel and have an identical working direction. The suspension strut is adjustable to at least two level positions. The second carrying spring has a spring rate that increases as the effective length of the suspension strut decreases.

First and second bump stops extend from one of the first and second plates to or toward the other of the first and second plates. A first shock absorber is disposed and selectively compressible between the pivot arm and the first bump stop. A second shock absorber is disposed and selectively compressible between the pivot arm and the second bump stop.

The invention relates to a spring support for a coil spring (15), comprising an annular receiving element (5) having a top side and a bottom side, wherein the top side is provided to receive one end of the coil spring (15), and comprising an annular damping element (3), which is in contact with the bottom side of the receiving element (5), wherein the damping element (3) furthermore has on its inside a collar which extends from the bottom side of the receiving element (5) in the direction of the coil spring (15), and wherein the collar is formed by bending from a disk-shaped basic form of the damping element (3). The invention furthermore relates to a method for producing a spring support according to the invention, in which a disk-shaped damping element (3) is first of all placed in a casting mold, and an annular receiving element (5) is then produced by being molded or injection-molded to the damping element (3), with the result that the bottom side of the receiving element (5) is in contact with the annular damping element (3).

Bonding the bush to the stabilizer bar, by surface pressure in the bonding surface (inner circumferential surface) of the hole-part of the bush being made uniform, bonding strength is obtained. The first arc part is formed at the opposite side of the opening of the U-shaped part of the bracket in the bonding and second arc part is formed in the opening side, in the hole-part of the bush. The first and second arc parts are circular arc parts being formed in circular arc shape or approximately circular arc shape or are ellipse arc part being formed in the ellipse arc shape or approximately ellipse arc shape. In the hole-part, the center of the first and second arc parts are separated. The curvature radius of the second arc part gets smaller than the curvature radius of the first arc part. The hole-part is formed in an oval shape.

A spring aid for a vehicle suspension includes a compliant tower attachable to elements undergoing suspension travel. The tower defines an axis of travel or center axis and includes a plurality of rings and a plurality of window frames connecting the rings. The rings are perpendicular to, and spaced along, the axis, and define a cylindrical cavity. The window frames define a plurality of windows between the rings. The suspension element may also include a core, which substantially fills the cylindrical cavity of the compliant tower. A rod may be disposed within the core and movable within the hole of the shelf.

A inverted type shock absorber, comprising: an outer cylinder; a damping cylinder including a cylinder body and a piston rod, wherein the cylinder body is coaxially sleeved within the outer cylinder; at least three bearings which are fixed at different upper-lower positions of an internal surface of the outer cylinder to support the external surface of the cylinder body such that the cylinder body is slidable against the outer cylinder along the expanding-compressing direction; and an rubber stabilizer which tightly surround the external surface of the cylinder body in such a manner that the rubber stabilizer is sandwiched between two of said at least three bearings such that the rubber stabilizer provides the cylinder body a stabilizing force which radially retains the cylinder body relative to the outer cylinder to stabilize the sliding between the outer cylinder and the cylinder body.

An upper mount assembly for a shock absorber of an automotive vehicle. The upper mount assembly comprises a top plate and a bottom plate spaced from the top plate. The top and bottom plates are fixedly secured to the vehicle and operatively coupled to the shock absorber. An inner hub is seated between the top and bottom plate. A damper is supported by the inner hub between the top and bottom plate for cooperating with the shock absorber. The damper includes a plurality of spaced apart grooves formed therein for selectively varying the spring rate of the damper to absorb loads from the shock absorber.

A damping rubber spring for an automobile suspension, including: n rubber layers (2), n being a natural number not less than 3; n+1 metal partition layers (1) including an upper partition layer (4) and a lower partition layer (5), the n rubber layers (2) and the n+1 metal partition layers (1) being laminated alternately with each other, and the upper partition layer (4) being disposed in parallel with the lower partition layer (5), wherein an m-th rubber layer (2) starting from the upper partition layer (4) has a thickness or cross section area that is the same as that of an m-th rubber layer (2) starting from the lower partition layer (5).

A suspension system for a vehicle includes an extendable and retractable actuator disposed at each side of a frame of the vehicle and pivotally attached at one end to a vehicle bracket and at the other end to a suspension bracket. The suspension bracket includes an actuator portion, an axle portion and a suspension arm, with the actuator portion and the suspension arm pivotable relative to an axis of the axle portion. When the actuator is extended or retracted, the actuator portion pivots about the axis of the axle portion and imparts pivotal movement of a suspension arm about the axis to adjust a height of the frame of the vehicle. The actuator includes an elastomeric element disposed between an outer end of a slide rod and an outer end of a ram rod, with the slide rod movable to absorb sudden movements of the frame or wheel.

An end member assembly (204; 404) that is dimensioned for use in forming a gas spring assembly (200; 400) can include an end member body (248; 448) that is dimensioned for securement to a flexible spring member (206; 406) of the gas spring assembly (200; 400). The end member assembly (204; 404) can also include a compliant support structure (250; 450) that is operatively connected to the end member body (248; 448) to support the end member body in spaced relation to an associated structural component (SC2). The end member body (248; 448) can include a side wall (256; 456) that extends in overlapping (OL1; OL2) relation with at least a portion of the compliant support structure (250; 450). The end member (204; 404) can also form at least one chamber (296; 508) within the end member body (248; 448) and compliant support structure (250; 450).
