A vehicle is provided which has a vehicle body, at least one hub of a wheel, and a suspension connecting the hub to the vehicle body. The suspension has a suspension arm hinged to the vehicle body and to the hub, a spring, and an electromechanical rotary actuator operable between an active adjustment condition and a damping condition of the motion of the suspension, via a leverage.

A shock absorber for a vehicle, the shock absorber having an absorber body with an outer surface, and a movable piston having a first end configured to couple with the vehicle, and a second end disposed within the absorber body. 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 change in a linear position of the magnet assembly.

A device for supplying hydraulic energy in a chassis system of a vehicle, including a first and a second motor-pump unit which are mechanically firmly connected to each other, the two motor-pump units preferably being designed identical in structure.

A vehicle is provided that has a vehicle body, a wheel assembly, a suspension linkage, and a cover panel. The vehicle body has an underside and defines a wheel arch that forms an opening in the underside of the vehicle body. The suspension linkage runs within the wheel arch and couples the wheel assembly to the vehicle body to permit motion of the rotation axis of the wheel assembly relative to the vehicle body. The suspension linkage further comprises a first suspension link coupled between the vehicle body and the wheel assembly, whereby the cover panel is coupled to the first suspension link so that the cover panel moves with the first suspension link. The cover panel further extends across part of the opening so that in forward motion the cover panel directs a rearward moving airflow across the opening.

A multi-purpose shock absorber for a vehicle suspension having an absorber body with an outer surface, and a movable piston having a first end disposed within the absorber body and a second end configured to couple with a part of the vehicle. 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 electric height control device may include: an oil storage part configured to store oil therein; a motor driving part inserted into the oil storage part and driven when power is applied thereto; a hydraulic block part coupled to the motor driving part, connected to the oil storage part, and configured to amplify oil; and a control part coupled to the hydraulic block part, and configured to control the motor driving part and the hydraulic block part.

A protective sheet enveloping an air suspension module of a vehicle is disclosed. The protective sheet comprises a first edge, a second edge, a third edge, a fourth edge, and a middle portion. The first edge, the second edge, the third edge, and the fourth edge having a pleat with a plurality of incises. The third edge and the fourth edge are in a perpendicular orientation with respect to the first edge and the second edge. The middle portion having a mesh encapsulated within the pleat of the first edge, the second edge, the third edge, and the fourth edge. The protective sheet envelopes around an outer circumferential surface of the air suspension module using fastening means. The plurality of incises provide flexibility for easy installation of the protective sheet over the air suspension module. The protective sheet protects the air suspension module during operation of the vehicle.

A suspension system for a vehicle includes a knuckle defining a bore therethrough. The suspension system includes a wheel hub rotatably mounted on the knuckle. Further, the suspension system includes an axle at least partially received within the bore of the knuckle and operatively coupled to the wheel hub. The suspension system includes a pump driven by the axle and configured to generate pressurized fluid. The suspension system includes an actuator receiving pressurized fluid from the pump.

A reciprocating compressor includes a cylinder including a cylindrical cylinder portion and a cylinder head portion provided on one side of the cylinder portion, and a piston mechanism reciprocably fittedly inserted on an inner peripheral side of the cylinder portion and including a piston defining a compression chamber and a non-compression chamber. A bottomed hole-shaped valve body housing portion is formed at the cylinder head portion. The valve body housing portion is opened to a piston side facing the piston in an axial direction of the cylinder portion. Further, a discharge valve unit and a valve holding member are provided in the valve body housing portion. The discharge valve unit is inserted in the valve body housing portion. The valve holding member holds the discharge valve unit in the valve body housing portion, and includes a communication hole establishing communication between the valve body housing portion and the compression chamber.

A multi-purpose shock absorber for a vehicle suspension having an absorber body with an outer surface, and a movable piston having a first end disposed within the absorber body and a second end configured to couple with a part of the vehicle. 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.
