摘要： A method and apparatus for dampening a structure in an aircraft. The apparatus comprises a housing, a first compartment located along an axis extending centrally through the housing, a second compartment located adjacent to the first compartment on the axis extending centrally through the housing, a first piston, a rod, and a second piston. The housing has an elongate shape. The first piston is located within the first compartment of the housing. The first piston defines a first chamber and a second chamber of the first compartment as the first piston moves within the housing. The rod is associated with the first piston and extends centrally through the first compartment and the second compartment. The second piston is coaxial to the first piston and located within the second compartment. The second piston moves relative to the rod to accommodate a flow of a fluid into the second compartment.

摘要： Hydraulic bump stops and bi-directional diverter valves may be used to protect hydraulic systems, including, for example in one embodiment, the hydraulic actuators of an active suspension system, from damage due to operation outside the normal operating range of the system. In some embodiments, a hydraulic bump stop may be used to slow down the motion of a piston at the extremes of the compression and/or extension strokes of an actuator. In another embodiment, a diverter valve may be used to protect a hydraulic motor/pump in a hydraulic system from an over-speed condition. When the piston in an active suspension system actuator moves at a speed in excess of a threshold value, one or more diverter valves may be used to divert flow away from the hydraulic motor/pump. In some embodiments, a diverter valve may be a dual or single spool bi-directional diverter valve.

摘要： A shock absorber comprising a generally tubular body defining a working chamber. A piston is slidable in the working chamber and separates a compression chamber from a rebound chamber of the working chamber. The working chamber contains damping fluid. The shock absorber comprises an electric generator fitted thereto. The generator comprises a turbine rotatably coupled to at least one magnet and coils adjacent the magnet. The shock absorber comprising a turbine flow path between the compression chamber and the rebound chamber, the turbine being supported for rotation in the turbine flow path driven to rotate by flow of damping fluid. Preferably the turbine flow path comprises a compression flow path and a rebound flow path and a turbine chamber, the compression flow path providing for flow of damping fluid from the compression chamber though the turbine chamber to the rebound chamber. One way valves are positioned in the compression and rebound flow paths so that flow only occurs in a respective flow path during compression and rebound of the piston. Movement of said damping fluid though either of said compression flow path or said rebound flow path causes the turbine to rotate in only one rotary direction to thereby generate an electric current in said at least one coil.

摘要： The present invention is a system for adjusting the height of vehicles that have coil spring suspensions. The invention may be added to existing vehicle suspensions without the need to remove and replace the existing vehicle suspension components. The invention includes cylinders, pistons, seals, dust shields, pressure pump(s) and storage tank(s). It also may optionally include electronic hardware, such as, an electronic controller and software, to control the functions of the system and sensor(s) which detect ground clearance and speed. The invention may be operated manually by a vehicle driver through push buttons, which may operate through the vehicle's existing cruise control buttons. Alternatively, the system can be automated through an electronic control unit (ECU) to avoid collision with obstacles in the vehicle's path.

摘要： A shock mount support assembly for a shock absorber of a suspension assembly of an axle/suspension system includes a shock support bracket formed with an opening. A fastener is disposed through the opening in the shock support bracket and an eyelet of the lower end of the shock absorber to loose-fit the shock support bracket to the shock absorber, and to the suspension assembly beam in a transverse direction. The shock support bracket includes at least one transversely elongated or oversized opening that aligns with an opening formed in the beam. A fastener is disposed through the pair of aligned openings in order to loose-fit attach the shock support bracket to the beam. During assembly, the eyelet fastener is tightened first drawing the shock support bracket transversely outboardly. The fastener disposed through the shock support bracket-to-beam attachment is tightened, rigidly attaching the shock support bracket to the suspension assembly.
