Abstract
The invention relates to a sway brace on rail vehicles. The aim of the invention is to find a solution in which the effort and expense needed to produce the sprung sway braces can be reduced and the transverse forces and the resultant wear occurring on deflection can be reduced to the minimum. This is achieved by the invention in that one end of the sprung sway braces in a special design is arranged in a support with defined guide surfaces while the other end is secured to the piston of a hydraulic cylinder via an axial rocker beating. In addition, there is a disc spring column above the sway brace.
Claims3
Sway brace with a sprung support and a supplementary spring, arranged on rail vehicles between first and second components, the sprung support being formed of a cylinder with a piston, whose piston space is connected with a pressure accumulator, and of a brace wherein
- a lower end of the brace is supported on a surface of the first component, at least one of the end face of the lower end of the brace and the surface being designed as a spherical surface, while an upper end of the brace is fastened by a joint to the piston, and
- a lateral surface of the lower end of the brace or an opposite surface on the first component is a rotation surface with two or more circular curves as a generatrix, while the respective other lateral surface or the opposite surface is constructed as a straight circular-cylindrical surface.
