A spacer element system for a vehicle suspension system, includes a receiver configured to be attached to a suspension component of the vehicle suspension system, and a spacer that is removably connected to the receiver. A vehicle suspension system includes a spring and the spacer element system, wherein the receiver is attached to the spring.

A vehicle includes a vehicle wheel, a vehicle frame and an adjustment mechanism configured to move the vehicle wheel relative to the vehicle frame. The adjustment mechanism includes a cam stud and a cam spacer. The cam stud extends at least partially through the vehicle frame. The cam spacer is rotationally fixed to the cam stud. Rotating the cam spacer moves the vehicle wheel relative to the vehicle frame.

In some examples, a vehicle suspension for supporting, at least in part, a sprung mass, includes a damper connected to the sprung mass, the damper including a movable piston. The vehicle suspension further includes an actuator and a controller. The controller may be configured to determine a frequency of motion associated with the sprung mass. When the frequency of motion is below a first frequency threshold, the controller may send a control signal to cause the actuator to apply a deceleration force to the sprung mass. Further, when the frequency of motion associated with the sprung mass exceeds the first frequency threshold, the controller may send a control signal to cause the actuator to apply a compensatory force to the sprung mass. For instance, a magnitude of the compensatory force may be based on a friction force determined for the damper.

A suspension system for a rear axle of a vehicle provided with a frame equipped with at least two side members, the suspension system connecting the axle to said side members and comprising a left side and a right side, each comprising an axle-holder assembly, a bellows, a leaf spring, first and second bars, and a torsion bar interposed between said left and right sides. The aforementioned elements of the suspension system being arranged to provide a functional layout having reduced costs and overall dimensions.

A modular axle clamp and riser system for use in a suspension system, which includes a top mount having a substantially flat upper surface, a top mount body which extends transversely to the flat upper surface, a pair of opposing ears which extend from the top mount body, and at least one top mount tooth extending from the top mount body in a direction opposite the ears. Also included is a wedge with at least one wedge tooth which matingly engages the at least one top mount tooth, a wedge upper surface, and a pinion angle surface. Further, the wedge defines a pinion angle between the wedge upper surface and the pinion angle surface. Moreover, an axle mount with at least one axle mount tooth which matingly engages at least one of the at least one top mount tooth and the at least one wedge tooth is provided.

An adjustable shock absorber system includes: a coil over shock absorber with a spring and a lockable adjustment ring; a protective cover assembly, optionally including top and bottom cover portions; a shock adjuster tool with a lever arm and a tool grip portion, including a band assembly, and a tool attachment assembly, including a connector member and a tool member; such that the tool grip portion detachably connects to the peripheral mounting surface of the lockable adjustment ring; whereby the shock adjuster tool can be used to adjust a preload of the coil-over shock absorber. Alternatively, an adjustable shock absorber system includes: a coil-over shock absorber with a spring and an adjustment ring; an adjustment ring assembly, which detachably interlocks with the adjustment ring; and a shock adjuster tool with a lever arm and a tool grip portion, which detachably connects with the adjustment ring assembly.

A hydraulic shock absorber includes a piston, a damper tube, a suspension spring, a plunger, a jack chamber, a pump case, a pump piston, a screw shaft, and a drive unit. Both end surfaces of the pump piston in a reciprocating direction are a first end surface demarcating the pump chamber, and a second end surface demarcating the gas chamber, the second end surface having a screw hole into which the screw shaft is screwed. The pump piston includes a space portion between a bottom plate defining the first end surface and the screw hole. The screw shaft has a through-hole connecting the gas chamber with the space portion.

A clamp for securing a link to a bar or a rod in order to accommodate multiple connection points. The clamp or sway bar clamp includes multiple connection points for securing a link to a sway bar. The sway bar clamp goes over the end of the sway bar. It converts a sway bar with one connection point to a sway bar with multiple connection points to adjust flex of the sway bar.

An independently driving wheel module includes: a base frame including an upper end fixed to a coupling surface of a vehicle body, and a rotation part coupled to the upper end of the base frame such that the rotation part is rotatable with respect to the upper end of the base frame; a connection link including a first end integrally coupled to the rotation part, and a second end having a shape extending downward from the first end of the connection link; a driving wheel disposed at a side of the second end of the connection link and coupled to the second end of the connection link; and a rotation plate including an upper and lower surfaces extending obliquely in misaligned directions, the rotation plate being interposed between the base frame and the vehicle body so as to be rotatable with respect to the base frame or the vehicle body.

A method for controlling an air suspension system of a vehicle includes: a) determining a bellows pressure-time characteristic curve for air admission to and release from the bellows of one air spring or the bellows of a plurality of air springs, the characteristic curve being normalized with the value of a supply pressure in a reservoir for compressed air, b) sensor measurement of a current pressure in the spring bellows of the air springs as well as the current supply pressure immediately before air admission thereto or air release therefrom, c) determining, from the normalized characteristic curve, the opening duration for the associated shutoff valve using the ratio of the measured bellows pressure to the measured supply pressure and the ratio of the provided target pressure to the measured supply pressure, d) opening the associated shutoff valve for the determined opening duration in order to set the provided target pressure.
