Motor vehicle chassis

A motor vehicle chassis comprising:

• 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 front wheel spring associated with a corresponding front wheel and at least one shock absorber associated with the corresponding front wheel in a first spring-shock-absorber arrangement, in which respectively the shock absorber is disposed within the front wheel spring, which is constructed as a coil spring, and each of the two rear-wheel suspensions is provided at least with one rear wheel spring (3) associated with a corresponding rear wheel and at least one shock absorber associated with the corresponding rear wheel in a second spring-shock-absorber arrangement, in which respectively the shock absorber is disposed outside the rear wheel 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 corresponding wheel 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 rear wheel 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) and the arrangement of the height positioning devices within the corresponding spring-shock-absorber arrangements.
