Pneumatic suspension and damping arrangement

摘要

A pneumatic suspension and damping arrangement (100) is especially for vehicles and can be fixedly mounted on the chassis at the upper region and to the wheel mount at the lower region thereof. The pneumatic suspension and damping arrangement includes at least two hermetically closed air springs (101, 102) filled with pressurized gas, whose volumes can be changed and which are connected via an air connection (134) to a pressurized gas source. The air springs are each enclosed by a movable wall formed by a flexible member (116, 124) and each roll off on a roll-off contour and are connected to each other via a throttle element (108) through which the gas can flow in two directions. The air springs are arranged one above the other and the roll-off contour of the first air spring (101) is defined in such a way by the second air spring (102) that the first air spring (101) rolls off on the second air spring (102). A connecting element of the upper cover (104) of the first air spring (101) with the roll-off piston (128) of the second air spring (102) runs outside of the two air springs (101, 102).
