There is a magnet assembly disposed around and external of the movable piston at the second end. The absorber has a sensor assembly having a sensor body coupled with the outer surface. An inner sensor body has a sensor disposed therein configured to detect a linear change in a position of the magnet assembly.

An air pressure adjusting device includes a compressor configured to compress air taken in from outside, a dryer connected to the compressor and filled with a reversible dehumidifying agent, a connection port through which air dehumidified by the dryer is supplied to another device, an exhaust valve provided between the compressor and the dryer and configured to discharge air in the dryer, and a switch valve provided between the dryer and the connection port and configured to switch between a first flow path having a large air flow rate and a second flow path having a small air flow rate.

A method for operating a compressor for a compressed air system of a motor vehicle, in particular an air suspension system, wherein an operating temperature of the compressor is determined and used as a criterion for the compressor to be operated until a switch-off temperature (T) is reached, wherein a switch-on duration (t) until reaching the switch-off temperature (T) is determined, and the determined switch-on duration (t) is adjusted by a parameter (LP) dependent on the switch-off temperature (T) reached.

A motion control system includes a spring that supports a body structure with respect to a rotating assembly, the spring including an internal working volume, a structure that is connected between the spring and the rotating assembly, and a reservoir that is located in the structure. The reservoir is in fluid communication with the internal working volume of the spring to allow exchange of air between the internal working volume of the spring and the reservoir.

A suspension system (vehicle) includes: an air suspension that is inserted between a vehicle body and each of wheels and that is capable of extending and contracting by means of pressure of working fluid; a compressed air control unit that controls the working fluid; an electric power supplier that supplies electric power to the compressed air control unit; and a power saver that stops flow of the working fluid when abnormality occurs in the electric power supplier. When a vehicle has a predetermined vehicle height, the power saver stops the flow of the working fluid, and when the vehicle has a vehicle height other than the predetermined vehicle height, the power saver allows the working fluid to flow until the vehicle height reaches the predetermined vehicle height, and then stops the flow of the working fluid.

A compressed air supply device for an air suspension system of a motor vehicle comprising a motor-driven compressor, a dryer, a discharge path from the dryer to the outside, and an adjustment device for changing a flow cross section of the discharge path is provided in the discharge path.

This invention pertains to sway bar systems, and a method of controlling their operation. Specifically, the present invention relates to provide a way of adjusting the response characteristics of a sway bar system by changing the structure of the typical sway bar links and regulating the modified structure by utilizing an electronically adjustable sway bar link. Said electronically adjustable sway bar link comprises a twin tube cylinder filled with mixed incompressible fluid and pressurized gas and forms a determined volume in order to host pressurized gas higher than fluid flow regulation functions, permitting a directional control valve to always remain fully submerged in incompressible fluid and to modify the fluid path between each tube of said twin tube cylinder, allowing closed or opened fluid flow operation, determined by a controlling device receiving an electronic input and piloting said directional control valve.

A vehicle includes a suspension system for providing configurable stiffness and damping. The system includes a plurality of hydraulic cylinders, each corresponding to a respective wheel of the vehicle, and one or more valve assemblies for controlling hydraulic fluid in the plurality of hydraulic cylinders to achieve a plurality of suspension modes affecting bounce, pitch, roll, and warp. The system also includes a plurality of accumulators acting as spring elements for storing and releasing the hydraulic fluid as the plurality of hydraulic cylinders compress and rebound. The system includes control circuitry for controlling the valve assemblies to achieve one or more suspension modes defining bounce, pitch, roll, and warp stiffnesses. By generating control signals for the valve assemblies, various interconnections or fluid paths can be achieved, corresponding to the suspension modes. The hydraulic cylinders are double acting, with rebound and compression volumes, and may be coupled to damping valves.

Methods and systems are provided for adjusting a height of an electric vehicle with an adjustable suspension system. In one example, a method comprises: during a vehicle stop event, adjusting a height of a skateboard frame of an electric vehicle via an adjustable suspension system, based on at least one sensor input indicative of a desired skateboard frame height. In this way, user activities, including loading and unloading, may be facilitated.

A fluid containment system comprises a frame, a tank, a rear suspension system, a front lifting assembly, a cooperative coupling mechanism adapted to couple the fluid containment system to a vehicle, and a rear lifting assembly. The front lifting assembly is adapted to lift the front of the tank. The rear lifting assembly is adapted to lift the rear of the tank. The fluid containment system comprises a working condition and a mobile condition. A lower portion of the frame rests on a surface when the mobile fluid containment system is in the working condition. The lower portion of the frame is elevated with respect to the surface when the mobile fluid containment system is in the mobile condition. The fluid containment system is adapted to be towed by the vehicle when the cooperative coupling mechanism is coupled to the vehicle and the fluid containment system is in the mobile condition.
