A roll stabilizer in the form of a stabilizer bar which has a connecting portion at each end. The connecting portion is configured such that at least two bores are arranged on a circle arc. The center point of the circle arc constitutes the upper pivot point of the connecting element.

A spring device (100) for a wheel suspension (200) for a vehicle (300) is described. The spring device (100) comprises an elongated elastic torsion device (102) configured to rotate about a central longitudinal axis (R) at a load (L). The torsion device (102) comprises elongated elastic elements (130) that comprise an internal cavity (132).

A motion control system includes a top mount, a bottom mount, a rigid housing, an air spring, and a linear actuator. The air spring transfers force of a first load path between the top mount and the bottom mount. The air spring includes a pressurized cavity containing pressurized gas that transfers the force of the first load path. The linear actuator transfers force of a second load path between the top mount and the bottom mount in parallel to the first load path. The rigid housing defines at least part of the pressurized cavity and transfers the force of the second load path.

A spring-absorber system for a wheel suspension of a motor vehicle includes a suspension spring with a spring constant k.sub.T and an absorber filled with a fluid and mounted in parallel to the suspension spring. The spring-absorber system also includes at least two additional spring modules via which a total spring constant k.sub.G of the spring-absorber system can be varied.

Provided is a vehicular holding device that, in an ON state, holds a vehicle component in a state where displacement of the vehicle component in an axial direction is restrained, and that, in an OFF state, holds the vehicle component in a state where displacement of the vehicle component in the axial direction is possible. The vehicular holding device includes at least one engagement part, a cam mechanism, and an axial direction restraining part. The at least one engagement part is at a position where the engagement part engages with an engaged part in the ON state, and is at a position where the engagement part is separated from the engaged part in the OFF state. The cam mechanism displaces the at least one engagement part from the OFF-state position to the ON-state position. The axial direction restraining part receives axial-direction force acting on the at least one engagement part.

This invention pertains to sway bar systems, and a method of controlling their operation. Specifically, the present invention relates to provide a way of adjusting the response characteristics of a sway bar system by changing the structure of the typical sway bar links and regulating the modified structure by utilizing a hydraulic control unit. Said hydraulic control unit independently modifies the fluid path within each said sway bar links by use of one electronically controlled bi-directional valve allowing for closed or opened flow operation, determined by an electronic input being received.

A driving robot includes a sensor, a loading member configured to load food, a stabilizer provided at a bottom portion of the loading member, the stabilizer including a top plate, a bottom plate, and damping plates provided between the top plate and the bottom plate, the damping plates configured to adjust damping, a driving device including a suspension and a wheel, and a processor configured to control the stabilizer and the suspension based on information of at least one of information associated with the food, information obtained from a driving map or information of surrounding situation detected by the sensor.

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 vehicle wheel suspension includes a suspension spring and an additional spring element. The additional spring element is disposed in a working chamber of a hydraulic cylinder. The working chamber, in hydraulic terms, is configured to be completely shut off by a check valve and the volume thereof with an opened check valve while activating a vehicle drive apparatus with braked vehicle wheels being variable by the anti-dive angle and/or the anti-squat angle. For such a volumetric variation of the working chamber, a hydraulic medium is flowable through the opened check valve.
