Support for a vehicle body on a chassis

A support for a car body (11) on a truck (10) of a rail vehicle, comprising:

• a fluid-actuated piston-cylinder unit (60) arranged between the car body (11) and the chassis (10), with a rocker support (12) also arranged between the car body (11) and the chassis (10), wherein said rocker support (12) comprises a first support part (13) and a second support part (14) which is arranged between the first support part (13) and a car part, each support part (13, 14) having a rolling surface (31, 25, 16) with which it rests on another rolling surface (25, 31, 17) and at least one rolling surface (31, 16) of the two contacting rolling surfaces (31, 25;
• 16, 17) is cylindrical and the contact between a pair of the rolling surfaces (31, 25;
• 16, 17) is linear;
• at least one support part of the two support parts (13, 14) is of annular development;
• the piston-cylinder unit (60) is located inside the at least one annular support part;
• and a cylinder (61) of the piston-cylinder unit (60) is provided with an outer flange (64) against which the annular support part rests via the rolling surface (16) and the piston (62) of the piston-cylinder unit (60) rests against another part;
• and
• wherein the outer flange (64) is provided with a rolling surface (17).
