Abstract: A pneumatic suspension system for a vehicle, in which the pneumatic suspension system includes a supply tank, a first set of air springs positioned on a first side of the vehicle; a second set of air springs positioned on a second side of the vehicle, and a dual-action dynamic valve positioned between the first set of air springs and the second set of air springs. The dual-action dynamic valve is connected to the supply tank, the first set of air springs, and the second set of air springs by a series of air hoses. The dual-action dynamic valve is adapted to supply air to either one of the first set of air springs or the second set of air springs while simultaneously exhausting air from the other one of the first set of air springs or the second set of air springs.

Abstract: A spring and damping arrangement for adjusting the spring rate and the driving position of a motorcycle includes a series circuit having at least one helical spring, an air spring unit, and a hydraulic actuating element. The spring rate of the air spring unit is changeable as a function of a force acting from the outside on the spring and damping arrangement, such that the driving position change resulting from the applied force is compensated by the hydraulic loading of the hydraulic actuating element, such that a defined driving position can be adjusted or maintained.

Abstract: The present invention is a system for adjusting the height of vehicles. The vehicle is supported by a hollow cylinder and a piston having an undersized piston skirt is mounted on the suspension system's coil spring, and sealingly slidable within the cylinder bore. When a fluid is introduced into the expandable pressure space between the piston and the cylinder top, the piston and cylinder are forced apart, raising the vehicle. The undersized piston skirt can extend beyond the end of the cylinder, allowing the piston a greater travel length within the cylinder bore. The invention may be operated manually by a vehicle driver through push buttons, which can be the vehicle's existing cruise control buttons. Alternatively, the system can be automated using a control unit to automatically adjust ground clearance to avoid collision with obstacles in the vehicle's path. In another embodiment, the lift system, or any lift system, is prevented from activating, and deactivates (if previously activated) if the vehicle is travelling at excessive speed.

Abstract: A load-based tire inflation system for a heavy-duty vehicle comprises at least one source of fluid pressure, suspension structure of the heavy-duty vehicle, a tire and wheel assembly and a system to control fluid pressure in the tire and wheel assembly. The suspension structure is located between a frame member and an axle and has a condition indicative of a weight of the heavy-duty vehicle. The tire and wheel assembly is operatively mounted to the axle and is in fluid communication with the source of fluid pressure. The control system controls fluid pressure in the tire and wheel assembly in response to the condition of the suspension structure.

Abstract: An active suspension system is configured in a strut arrangement. The active suspension system comprises a hydraulic actuator and a hydraulic pump/electric motor assembly, wherein the actuator movement is preferably in lockstep with the hydraulic motor-pump and electric motor-generator combination. Torque in the electric motor is instantaneously controlled by a controller to create an immediate force change on the hydraulic actuator. The hydraulic actuator is configured so that it can be used as a strut whereby the actuator has sufficient structural rigidity to carry the applied suspension loads while capable of supplying damper forces in at least three quadrants of the force velocity graph of the suspension actuator operation. Embodiments disclosed include low cost active suspension systems for a MacPherson strut application.

Abstract: An active suspension system 1 for a vehicle. The suspension system 1 comprises a hydraulic actuator 4 for connection to the vehicle, an accumulator 30 arranged to provide fluid to the actuator 4 and a spool valve 16. The spool valve 16 comprises a spool 18 mounted for movement between a first position in which the flow of fluid from the accumulator 30 to the actuator 4 is prevented and a second position in which fluid can flow from the accumulator 30 to the actuator 4 via the spool 18 thereby causing movement of the actuator 4.
