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.
Claims9
An apparatus for compensating relative dynamic movement of the passenger space of a vehicle comprising;
- at least one support means mounted to the chassis of the vehicle, the support means having a piston supported by the passenger space by flexible means;
- a fluid circuit providing a source of pressure or a non-pressurized return;
- a directional control means for connecting the pressure side of the piston to either the source of pressure or to the non-pressurized return;
- a lever means supported by the passenger space, the lever means having a first arm means for actuating the directional control means and a second arm means;
- and
- an adjusting cylinder means having a piston connected to the second arm means, the pressure side of the adjusting cylinder piston being in fluid connection with the pressure side of the support means piston by an adjustable fluid throttling means.
