Abstract
The invention provides a support unit for drivers' cabs which actively compensates for any relative movement between chassis and cab by providing at least one support cylinder which is axially rigidly mounted on the chassis with its support piston and flexibly supported on the cab by its cylinder, the cylinder forming a movement-producing unit with a directional control valve whose body alternately connects the front side of the support piston to the pressure side of a constant-pressure circuit or to a non-pressurized outlet and is attached to the cab.
