Abstract

An air suspension for a motor vehicle is provided. The air suspension 6 is for at least two axles 2, 3 of a motor vehicle 1. Each axle 2, 3 extends from a first side R of the vehicle to a second side L of the vehicle 1. The air suspension 6 comprises for each axle 2, 3 at least one first air bellows 7 on the first side R of the vehicle 1 and at least one second air bellows 8 on the second side L of the vehicle. Furthermore the air suspension 6 comprises a pressure tank 12 for storing compressed air, a valve system 13 connected to the air bellows 7, 8, at least one pressure sensor 9 for detecting a pressure in an air bellows 7, 8, and a control unit 11 for the valve system 13 adapted to electronically control the pressure in the air bellows 7, 8 by operating valves 13.1 to 13.6 of the valve system 13. The valve system 13 comprises at least one equaliser valve 13.1 connecting pneumatically two air bellows 7, 8 for different axles 2, 3 so that opening the equaliser valve 13.1 allows air to flow between the two air bellows 7, 8.
