The invention relates to a support for a vehicle body (11) on a chassis, especially a bogie (10) of a rail vehicle. A prior art support comprises a fluid-actuated piston-cylinder unit (60) fitted between the vehicle body (11) and the chassis (10) and a rocking stanchion (12) also fitted between the vehicle body (11) and the chassis (10) which comprises a first supporting component (13) and a second one (14) fitted between the first (13) and a vehicle component (10). Each supporting component (13, 14) has a break-away surface (31, 25, 16) bearing on another, where at least one break-away surface (31, 16) is cylindrical and the contact area between a pair of surfaces (31, 25, 16, 17) is linear. It is the aim of the invention to design such a support in such a way that it requires little space and in particular the distance between the vehicle body (11) and the chassis (10) can be very small. This is attained in that at least one of the two supporting components (13, 14) is annular, the piston-cylinder unit (60) is fitted inside the at least one annular supporting component (14) and the cylinder (61) of the piston-cylinder unit (60) has an outer flange (64) with a break-away surface (17) on which bears one (16) of the break-away surfaces of the annular supporting component (14), and the piston (62) of the piston-cylinder unit (60) bears on another component (10).
