Abstract
A motor vehicle chassis is provided having a base structure that can be hydraulically adjusted in level between a raised and a lowered position. A hydraulic adjuster is assigned to one of the two foot points of the corresponding suspension spring in each of the four wheel suspensions. At least two of the adjusters can be pressurized in parallel by a common hydraulic aggregate comprising a tank and a motor-pump unit and activated by a control unit. The at least two hydraulic adjusters that can be pressurized by the common hydraulic aggregate communicate hydraulically with the accumulator chamber of a spring-piston accumulator, which has at least one piston-position transmitter linked by signal transmission to the control unit.
