Abstract
A support for a car body on a chassis, in particular on a truck of a rail vehicle. A support comprises a fluid-actuated piston-cylinder unit arranged between car body and chassis, and a rocker support arranged also between car body and chassis which comprises a first support part and a second support part which is arranged between the first support part and a part of the car. Each support part has a rolling surface via which it rests on another rolling surface, in which connection at least one rolling surface of the two rolling surfaces contacting each other is cylindrical and the contact between a pair of rolling surfaces is linear. The support part takes up little space. The distance between the car body and the chassis can be very small. This is achieved in that at least one of the two support parts is developed in annular shape; that the piston-cylinder unit is located within the at least one annular support part; and that the cylinder of the piston-cylinder unit is provided with an outer flange having a rolling surface against which the annular support part rests via a rolling surface, and the piston of the piston-cylinder unit rests on another part.
