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.

Claim (Index 1):
A motor vehicle chassis comprising:\n a basic structure ( 1 ), two front wheels connected thereto via one front-wheel suspension each; and two rear wheels connected thereto via one rear-wheel suspension each, wherein each of the two front-wheel suspensions is provided at least with one spring associated with the wheel in question and at least one shock absorber associated with the wheel in question in a first spring-shock-absorber arrangement, in which respectively the shock absorber is disposed within the spring, which is constructed as a coil spring, and each of the two rear-wheel suspensions is provided at least with one spring ( 3 ) associated with the wheel in question and at least one shock absorber associated with the wheel in question in a second spring-shock-absorber arrangement, in which respectively the shock absorber is disposed outside the spring, which is constructed as a coil spring, with the following features: respectively one hydraulic height-positioning device with a cylinder-piston arrangement ( 20 ) acting on a foot point ( 4 ) of the spring ( 3 ) in question is associated with all four wheel suspensions; the cylinder-piston arrangement ( 20 ) can be pressurized respectively by a hydraulic aggregate ( 21 ) comprising a decentralized hydraulic pump ( 25 ) associated with the wheel in question and respectively driven by an electric motor ( 22 ); each hydraulic height-positioning device comprises a complex, integrated electrohydraulic positioning assembly ( 5 ) comprising the respective hydraulic aggregate ( 21 ) and the associated cylinder-piston arrangement ( 20 ), with a specific adapter ( 6 ), in which the respective cylinder-piston arrangement ( 20 ) is integrated in such a way that no exposed hydraulic lines of any kind exist between the respective hydraulic pump ( 25 ) and the associated cylinder-piston arrangement ( 20 ); the cylinder-piston arrangement ( 20 ) comprises respectively an annular hydraulic working chamber ( 18 ); an annular hydraulic-fluid storage container ( 19 ) that changes its volume inversely relative to the annular working chamber ( 18 ) is disposed axially offset from the annular hydraulic working chamber ( 18 ) of the cylinder-piston arrangement ( 20 ); the hydraulic height-positioning devices of the front wheels and the hydraulic height-positioning devices of the rear wheels differ with respect to the adapter ( 6 ) in such a way that, in the first spring-shock-absorber arrangement, the hydraulic aggregate ( 21 ) is disposed outside the coil spring and, in the second spring-shock-absorber arrangement, at least the electric motor ( 22 ) of the hydraulic aggregate ( 21 ) is disposed within the spring ( 3 ); nevertheless, the hydraulic height-positioning devices of the front wheels and the hydraulic height-positioning devices of the rear wheels are identical in design, except for the respective adapter ( 6 ).
