Device for regulating the levelling of vehicle e.g. fork-lift truck

摘要

The device has a vehicle body with a rear section and a rear axle (44) under the rear of the body. A supporting yoke (30) linked to the body can pivot about a transverse axis in a vertical plane and rotatably holds the rear axle. A hydraulic cylinder (48) mounted between the yoke and body with two pressure chambers (58,60) can raise and lower the rear axle wrt. the body. Cylinder controllers detect an inclination of the vehicle body and supply the first or second chamber of the cylinder with pressurised medium to compensate for the inclination wrt. the horizontal.
