A hydropneumatic suspension system for vehicles, at least consisting of an axle suspension (10) and a cabin suspension (12), which for supplying them with pressurized fluid, can be connected to a pressure supply source, is characterized in that both the axle suspension (10) and the cabin suspension (12) can be actuated jointly by means of an control device (14), and in that, by means of a priority detection system (16) involving a sensor device (18) for the respective suspension (10, 12), the supply with pressurized fluid of the one suspension (10, 12) takes precedence depending on demand over the other suspension (12, 10).

A suspension system is disclosed utilizing oil addition and subtraction to actuate an accumulator to control position and stiffness in an Emulsion Shock/Oleo Pneumatic strut/Air spring strut. The strut maintains ride height for a wide variation in sprung mass and adjusts for the expansion/compression of the gas due to variations in temperature. The strut provides spring and damping characteristics.

A damper assembly for a vehicle suspension system includes a first damper and a second damper. The second damper includes a housing including a wall that defines an aperture, the wall and the first damper at least partially defining a chamber. The second damper also includes a piston positioned within the chamber, a conduit defining a flow path that includes the aperture, and a flow control device disposed along the flow path. The second damper is configured to provide a damping force that varies based on the position of the piston within the chamber.

The invention relates to a running gear structure (4) for a commercial vehicle. The running gear structure comprises a lower transverse strut (8) and an upper transverse strut (9). The lower transverse strut (8) and said upper transverse strut (9) are fixedly connected to each other. The upper transverse strut (9) comprising two recesses (12, 13) which limit a space (14) located above the lower transverse strut (8). The space (14) is open at least in upper direction and dimensioned for accommodating a suspension spring (6). Preferably, an axle body and longitudinal swinging arms (22, 23) of the running gear structure (4) have a skeletal design with a plurality of struts (5). It is possible that the running gear structure (4) is L-shaped in a side view. Here, one leg of the L is formed by a horizontal structure part forming the longitudinal swinging arms (22, 23) whereas the other leg of the L is formed by a vertical structure part forming the axle body.
