Abstract
A device for the secondary suspension of a body of a rail vehicle, the device comprising a spring element which is between the body and a bogie and to ensure at least one raised transport level for the body during the journey of the rail vehicle. The spring element can be compressed by a traction cylinder when the rail vehicle is stationary, in order to adjust a sunken platform level for the body, which is arranged below the raised driving level. The traction cylinder is provided with means for mechanically decoupling the advancing movement of the body from a pressure reduction in the pressure chamber of the traction cylinder.
