Abstract:
In a motor vehicle chassis, at least one wheel suspension, which comprises a spring in the form of a coil spring, has associated therewith a hydraulic height adjustment device having a cylinder-piston arrangement which acts on a base point of the coil spring. The cylinder-piston arrangement can be supplied by a decentral hydraulic aggregate which is associated with the relevant wheel and comprises a storage container for hydraulic fluid and a hydraulic pump driven by an electric motor. At least the electric motor of the hydraulic aggregate is situated within the coil spring.

Claim (Index 1):
A motor vehicle chassis comprising:\n a basic structure ( 1 ) and several wheels connected thereto via one wheel suspension each, wherein at least one first wheel suspension is provided with a spring ( 3 ), constructed as a coil spring ( 2 ) and associated with the wheel in question, wherein furthermore a hydraulic height-positioning device is associated with the first wheel suspension, with, acting on a foot point ( 4 ) of the coil spring ( 2 ) and comprising a hydraulic working chamber ( 18 ), a cylinder-piston arrangement ( 20 ), which can be pressurized by a decentralized hydraulic aggregate ( 21 ) comprising a storage container ( 19 ) for hydraulic fluid and a hydraulic pump ( 25 ) driven by an electric motor ( 22 ) and which is associated with the wheel in question, wherein at least the electric motor ( 22 ) of the hydraulic aggregate ( 21 ) is disposed within the coil spring ( 2 ), wherein the first wheel suspension is provided with a shock absorber, associated with the wheel in question and disposed outside the spring; wherein the hydraulic working chamber ( 18 ) of the hydraulic cylinder-piston arrangement ( 20 ) annularly surrounds the electric motor ( 22 ) of the hydraulic aggregate ( 21 ) and/or its hydraulic pump ( 25 ); and wherein the hydraulic-fluid storage container ( 19 ) is constructed annularly, surrounds the electric motor ( 22 ) of the hydraulic aggregate ( 21 ) and/or its hydraulic pump ( 25 ), and has a volume that varies inversely relative to the volume of the hydraulic working chamber ( 18 ) of the cylinder-piston arrangement ( 20 ).
