Abstract:
A shock absorber includes a first end and a second end that reciprocate relative to one another. The shock absorber includes a gas spring chamber, a damping chamber, and a floating piston. The first side of the floating piston is in fluid communication with the gas spring chamber. The second side of the floating piston is in fluid communication with the damping chamber. The gas in the gas spring chamber applies pressure against the floating piston, which applies pressure to the substantially incompressible fluid in the damping chamber. This pressure transfer may be adequate to minimize or prevent cavitation.

Abstract:
A combined spring compensation suspension device for a vehicle includes a free spring, a compensation spring, a compensation spring pre-tightening device, a vibration isolation block, a light damping shock absorber and a guide mechanism. The compensation spring pre-tightening device is installed at an upper end of the compensation spring. The guide mechanism is used to connect a wheel with a vehicle body. An elastic element on the suspension device of the vehicle is composed of the free spring and the compensation spring. A suspension load has a compensation interval nearby a static deflection stroke of a suspension. When the suspension load is changed in the compensation interval, the stroke is not changed or is slightly changed. Only when the suspension load exceeds the compensation interval, the suspension stroke can be changed. Controllability and comfort of the vehicle adopting the design can be simultaneously improved.
Abstract:
An air spring with damping characteristics for a suspension assembly of a heavy-duty vehicle includes a bellows and a piston. The bellows includes a bellows chamber. The bellows is attached to a main member of the heavy-duty vehicle and to the piston. The piston includes an open bottom that is sealingly closed by a disc attached to the open bottom. The piston and the disc define a piston chamber. The piston is mounted on the suspension assembly of the heavy-duty vehicle. The bellows chamber and the piston chamber are in fluid communication with each other via at least one opening, wherein airflow between the bellows chamber and the piston chamber provides damping to the suspension assembly of the heavy-duty vehicle.
Abstract:
The present invention relates to a suspension strut for a motor vehicle with a vibration damper, with a supporting spring and with a height-adjustment device, with which the height of the vehicle body of the motor vehicle can be changed, and wherein the suspension strut has an auxiliary spring having a lower spring characteristic than the supporting spring, by means of which auxiliary spring a residual prestress can be produced in the supporting spring when the vibration damper is extended, and wherein the auxiliary spring is integrated in the height-adjustment device.

Abstract:
A shock absorber includes: a metal cylindrical outer tube; a rod inserted into the outer tube, the rod being capable of moving in the axial direction; a bump cushion attached to an outer periphery of the rod that protrudes from the outer tube; a synthetic resin bump stopper formed in a cap shape and fitted to one end in the axial direction of the outer tube, the bump stopper being configured to be abutted by the bump cushion during maximum compression; and a sacrificial corrosion part disposed between the outer tube and the bump stopper, the sacrificial corrosion part being configured to contact a metal surface of the outer tube. The sacrificial corrosion part is made of a metal having a higher ionization tendency than the outer tube, and thereby corrosion of members is suppressed.
Abstract:
An air spring includes a bellow at least partially delimiting at least one working chamber that is constructed and arranged to be filled with compressed air. A guide tube surrounds at least a portion of the bellow. A bonding agent solely fixes a portion of the bellow to the guide tube. A piston is associated with the bellow. The bellow is constructed and arranged to roll with respect to an outer surface of the piston and an inner surface of the guide tube.
Abstract:
A gas spring and gas damper assembly (110; 200; 400) can include a gas spring assembly (128; 202; 402) and a gas damper assembly (130; 204; 404). The gas spring assembly can include opposing end members (206, 208; 406, 408) and a flexible spring member (210; 410) secured there between that at least partially forms a spring chamber (212; 412). One of the end members (208; 408) can include an end member chamber (268; 468) that is separated into a plurality of damping chambers (292, 294; 492, 494). Damper pistons (300, 302; 500, 502) are disposed within the damping chambers (292, 294; 492, 494) and are connected to the other end member (206; 406) by way of a damping rod (276; 476).
Abstract:
The invention relates to a wheel suspension for a motor vehicle, said wheel suspension having a multi-link assembly (21) of links that are hinged to the vehicle body, in particular to a subframe (1) of the vehicle body, and to a hub carrier (23), and having a rotary actuator (27) for active chassis control, said rotary actuator having a motor-gear unit (29) with which torques can be transmitted, via at least one torsion bar (31), as adjusting forces to said multi-link assembly (21). According to the invention, at least one of the links (14, 16) of the multi-link assembly (21) limits, in the longitudinal direction (x) of the vehicle towards the front or towards the back, a free space (39) in which said motor-gear unit (29) of the rotary actuator (27) is at least partially arranged.
