Abstract: A pneumatic suspension system for a vehicle is provided comprising a mounting arrangement for mounting a portion of the vehicle on a chassis; the mounting arrangement including at least one pneumatic spring to be arranged and coupled between the portion of the vehicle and the vehicle chassis. A vehicle state control system is provided that provides a pressure set value in the pneumatic spring and a pressure controller is arranged to a valve device alternatively for pressurizing or depressurizing the each pneumatic spring. The valve device comprises at least a first valve having a valve outlet coupled to the spring terminal and a valve inlet communicatively coupled to the pressure terminal. A support structure (102) distinct from the sealing edge (104) is provided arranged to providing supporting contact to the sealing face to counteract deformations of the sealing face.

Abstract: The invention relates to a suspension assembly (1) for suspending a cabin (2) of a truck or the like vehicle. The assembly comprises a plurality of spring members (4a-d) arranged between the cabin (2) and a chassis of the vehicle, and a torsion bar (5) extending between at least two of said spring members (4a-d) so as to increase the roll stiffness of the assembly. The assembly further comprises an actuator (6) with which a torsion angle of the torsion bar (5) can be adjusted allowing active roll stabilization of the cabin (2).
