Abstract: A vibration damper with a piston, a piston rod fastened to the piston, a working chamber divided by the piston into a first working chamber and second working chamber, and a generator drivable by movement of the piston rod. The damping force of the vibration damper can be influenced by energization of the generator. An energizable component part is provided that short-circuits the windings of the generator when unenergized and cancels the short circuit when energized.

Abstract: Energy-recuperating vibration damper having a cylinder in which a displacer executes a limited operating movement in a working chamber so that a pressurized fluid is supplied to a fluid motor which drives a generator. A compensation chamber compensates for a change in volume of the pressurized fluid. A pressure accumulator is provided in addition to the compensation chamber, which pressure accumulator communicates with and is parallel-connected to the fluid motor.

Abstract: A vibration damper having a cylinder filled with pressurized medium and in which a displacer drives a generator. The vibration damper has a compensation element that compensates pressure peaks from the displacer movement relative to the generator. The compensation element is constructed as a variable-torque clutch.

Abstract: In a suspension for a motor vehicle having at least one front axle and at least one rear axle, at least two vibration dampers which are separated from one another by a longitudinal axis of the vehicle are arranged at each axle. The sum of the occurring damping forces of the vibration dampers can be adjusted, and a vibration damper with adjustable damping force and a nonadjustable vibration damper are arranged at least at one vehicle axle.

Abstract: Gas spring includes a cover which works together with a rolling bellows and a bottom part to form a gas-filled spring space, where at least part of the outside surface of the rolling bellows is covered by a sleeve. The sleeve provides a receptacle for at least one sensor which detects the stroke position of the gas spring.

Abstract: Vibration damper includes a cylinder filled with a damping medium in which a piston rod with a piston is guided in an axially movable manner, wherein the piston divides the cylinder into a work space on the piston rod side and a work space remote of the piston rod. A bypass connects at least one of the two work spaces with a first work chamber in a housing in which an axially movable separating piston separates the first work chamber from a second work chamber, the bypass being controlled by a switchable valve.

Abstract: Spring strut with a pneumatic spring and an oscillation damper which can be adjusted as a function of the support pressure. The pneumatic spring has a spring space bounded by a U-type bellows, which spring space is pneumatically connected to a damping device which can be adjusted as a function of a support pressure. A component which having a duct connects the spring space and the damping device is embodied without a hose and is integrated in the spring strut in such a way that it does not form any essential surface change in an unrolling piston associated with the U-type bellows and the unrolling piston forms at least a part of this duct.

Abstract: The invention is directed to a vibration damper such as a shock strut for articulated installation between a car body and a wheel guide part in a motor vehicle by a quick connection. For this purpose, the vibration damper on the shock strut, together with an elastic joint and a connection part, forms a constructional unit or assembly unit. The quick connection is formed between the connection part and the body or the wheel guide without a catch connection and in a rigid manner, so that relative movement is prevented between the connection part and the body or wheel guide part.

Abstract: The invention relates to a spring-and-damper unit with an external storage device for installation between a vehicle body and a wheel guidance part. To create the greatest possible supporting length for the piston rod in a given installation space, the storage device is preferably connected to a spring plate, on which rests a carrying spring embodied as a coil spring, while the spring plate is arranged in a pressure-tight fashion on the cylinder or a container surrounding the cylinder. The interior of the cylinder or the container is hydraulically connected to the storage device via a connecting channel in the spring plate.

Abstract: An arrangment for securing against rotation for a structural component part of a vibration damper or of a shock absorber leg for motor vehicles, which structural component part is provided with a pin type pivot bearing. A piston rod and/or a receptacle is connected, in each instance via a flexible pin type pivot bearing, with the vehicle body or with a wheel guide part. The arrangement for securing against rotation acts between the piston rod and/or the receptacle and the part which is fixed with respect to the vehicle and connected therewith. The arrangement for securing against rotation is formed by a flexible structural component part which participates in the articulated movements and is arranged so as to be positioned between the piston rod and/or the receptacle or cylinder and the part which is fixed with respect to the vehicle.

Abstract: A piston-cylinder unit includes a cylinder in which a piston rod is located so that the piston rod can move axially. A first connection mechanism is connected to the cylinder, and a second connection mechanism is connected to the piston rod. A positioning cylinder, with a pressure medium connection, is effectively connected to one of the first and second connection mechanisms. The distance between the first and second connection mechanisms can be set by the addition or discharge of pressure medium to or from the positioning cylinder. The positioning cylinder is located in series with the cylinder, and the piston rod forms a guide path or track for the positioning cylinder.
