Abstract
Air suspension system with a compressed air container of an air suspension system for a motor vehicle with a vehicle frame and a vehicle body, comprising a number of elastic air springs which are connected to the reservoir, whereby the air springs and the reservoir are to be considered as compressed air containers, characterized by the fact that at least one compressed air container is located inside a cavity formed by at least one vehicle part which is independent of the air suspension system strictly speaking.
Claims20
A suspension system of a motor vehicle, said suspension system comprising:
- elastic air springs and at least one compressed air container;
- one of said elastic air springs being connected to said at least one compressed air container;
- said vehicle having a body and a plurality of wheel suspensions supporting said body;
- said plurality of wheel suspensions being connected to said body;

- said at least one cavity being disposed a substantial distance away from a substantial portion of said wheel suspensions;
- said at least one cavity having at least one wall;
- said at least one compressed air container comprising means for contacting said at least one wall of said at least one cavity upon filling of said at least one compressed air container with compressed air;
- at least one portion of said at least one wall being disposed to permit the position of said at least one portion to be changed with respect to the rest of said cavity;
- said at least one portion comprising an axially movable plate;
- a drive mechanism;
- and
- said drive mechanism being connected to said movable plate to permit movement of said movable plate and to change the volume of said at least one cavity.
