Abstract
In a motor vehicle chassis, all four wheel suspensions each have associated therewith a hydraulic height adjustment device having a cylinder-piston arrangement which acts on a base point of the relevant spring and is supplied by a decentral hydraulic aggregate. The hydraulic height adjustment devices each comprise a complex, integrated electrohydraulic adjustment assembly comprising the allocated hydraulic aggregate and the associated cylinder-piston arrangement and having a specific adapter into which the allocated cylinder-piston arrangement is integrated in such a way that there are no exposed hydraulic lines between the allocated hydraulic pump and the associated cylinder-piston arrangement. The front wheel height adjustment devices and the rear wheel height adjustment devices differ in terms of the adapter.
