Abstract
Abstract An installation for stabilizing the vehicle body against curvetilting, in which an erecting force is exerted on the side of the vehicle body disposed on the outside of the curve, whereby a pressure medium is supplied in dependence on the curve drive of the vehicle directly to the pistons of cylinder-piston units connected between the wheels and the vehicle body in such a manner that the cylinder-piston unit associated with the wheel on the inside of the curve is shortened in the sense of a lowering of the vehicle body and the cylinder-piston unit associated with the wheel on the outside of the curve is lengthened in the sense of a lifting of the vehicle body.
