摘要： A shock absorber assembly (10) includes a damping adjustment mechanism that can easily be incorporated into a twin cylinder design. The shock absorber includes an outer cylinder (12) and an inner cylinder (14) mounted within the outer cylinder. The inner cylinder is spaced apart from the outer cylinder to define a gap (16). A piston (24) is mounted within a fluid filled chamber formed within the inner cylinder to dampen vibrations. Holes are drilled into the wall of the inner cylinder to provide fluid ports (26, 26a, 26b) that can communicate with the gap to form a bi-directional fluid path as the piston moves back and forth within the chamber to dampen vibrations. To provide variable damping, the outer cylinder includes an eccentric inner diameter to outer diameter profile that allows damping adjustment between high and low damping forces. The damping force is adjusted by rotating the outer cylinder relative to the inner cylinder to vary the size of the gap with respect to the ports.

摘要： A shock absorber for a vehicle suspension includes a pneumatic actuator that is fluidly connected to a compressed air source in the vehicle suspension, such as a suspension air bag. The pneumatic actuator cooperates with an adjustment mechanism housed within the shock absorber to adjust damping. The shock absorber includes a main rod that supports a piston for axial movement within a cylinder body. The piston separates the cylinder body into first and second fluid chambers. The adjustment mechanism includes an adjustment rod that is received within an axial bore formed within the main rod. The adjustment rod is axially moved within the axial bore by the pneumatic actuator to uncover and cover a plurality of bores that are in fluid communication with at least one of the first and second fluid chambers. The pneumatic actuator includes a plunger having a tapered surface that engages the adjuster rod to move the adjuster rod in a desired direction to adjust damping. A fitting and a restrictor plug cooperate to fluidly connect the pneumatic actuator to the compressed air source and to meter air flow to attenuate pressure spikes.

摘要： A shock absorber assembly (10) includes a damping mechanism that adjusts to compensate for operation at elevated temperatures. A member (24, 26) made of two dissimilar materials permanently bonded together with one material having a higher expansion coefficient than the other material provides a biased response toward the material with the lower expansion coefficient. This biased response compensates for incremental pressure changes in the shock absorber due to operation at elevated temperatures to provide constant damping regardless of temperature.

摘要： An air spring suspension damper assembly includes a first housing and a second housing which telescope relative to each other. An actuating member, such as a cable, is connected to a height leveling valve contained in one of the housings and is attached to the other housing. The actuating member moves a member, such as a rotating cam, a rotating valve plate and/or a rotating valve, such that changes in suspension height rotate the member. Rotation of the member selectively opens inlet and exhaust flow paths to control air pressure in the damper assembly and to maintain air suspension height at a predetermined height.
