A vibration damper, assigned to a wheel of a vehicle, includes a damper cylinder, a damper piston with a piston rod configured to be guided in the damper cylinder, and a damper chamber, formed in the damper chamber on each side of the damper piston. The vibration damper further includes a pressure accumulator, in the form of a gas pressure cushion, connected to the damper chamber lying opposite the piston rod. The vibration damper is mounted on the vehicle body by a damper mount with a rubber-elastic body that is deformable in a shifting direction of the damper piston. A hydraulic pressure chamber is formed in the damper mount, and is connected via a fluid-conducting connection to the damper chambers whose volumes are respectively reduced when the wheel is deflected in relation to the vehicle body. The damper chambers are connected hydraulically to one another via a hydraulic pump driven by a motor. The damper mount includes a spring element that acts on the rubber-elastic body in the shifting direction of the damper piston, such that a spring force of the spring element, in the case of a stationary damper piston and equality of pressure in the two damper chambers, results in forces acting on the rubber-elastic body in the shifting direction of the damper piston to at least approximately cancel one another out.

A compliance compensator apparatus provides a mechanically compliant coupling between, e.g., a robot arm or robotic tool and a mechanical load. The compliance compensator apparatus comprise a base component and a compliance component attached to the base component and independently moveable in several aspects. The compliance component may move, with respect to the base component, axially, transversely, rotationally, and skew, in response to mechanical force from an engaged load. When the load is disengaged, the compliance compensator apparatus returns to a reset position wherein the compliance component is spaced apart from, but parallel to, the base component.

An integrated and self-contained suspension assembly having a gas spring integrated with a shock absorber (damper) is described. The rigid gas cylinder of the air spring is divided into a first gas chamber and a second gas chamber. A flow port connects the first and second gas chambers, and can be manually opened or closed by valve and a simple one-quarter turn rotation of an external knob to instantly switch the gas spring between two different spring rates. The different spring rates are functions of the separate or combined volumes of the two. gas chambers. The integrated suspension assembly is compactly packaged and self-contained, i.e., does not require any externalities, such as gas sources or electricity, to operate.

A piston rod (15) and a first piston (13) are arranged in the interior of an external cylinder (11) and internal cylinder (12); a second piston for absorbing the change of volume of operating fluid (24) is also arranged therein. Also, a first return spring (18) for returning the piston rod (15) to the interruption position is provided and a second return spring (20) for returning the operating fluid 24 into the high-pressure chamber (25) by pressurizing the second piston (14) is provided. In addition, the air in the interior of the buffering device (10) is withdrawn by a vacuum pump (38), and operating fluid (24) is thus introduced in a degassed condition.

A fluid-filled vibration damping device including: a first mounting member; a second mounting member; a main rubber elastic body elastically connecting the first and second mounting members; a pressure-receiving chamber whose wall is partially constituted by the main rubber elastic body; an equilibrium chamber whose wall is partially constituted by a flexible film, the pressure-receiving chamber and equilibrium chamber being filled with a non-compressible fluid; and an orifice passage which connects the pressure-receiving chamber and the equilibrium chamber to each other. A turbulence generating part is formed in a middle portion of the orifice passage in a length direction causing turbulence to be generated depending on a flow rate of a flowing fluid.

An arrangement for mounting a suspension spring of a spring strut for a motor vehicle may include a spring plate that is arranged on a damper tube of a vibration damper of the spring strut such that an end side of the suspension spring is supported on the spring plate. A protective element for protecting a piston rod of the vibration damper may also be attached to the spring plate. The spring plate may include features that help minimize or even eliminate contact between the protective element and the damper tube. For example, the spring plate may include tongues that extend from a ring-shaped main structure of the spring plate, wherein inner sides of the tongues may lie against the damper tube and outer sides of the tongues may guide the protective element.
