Vertical and side force components measuring appts. for railway vehicle wheel - achieves simultaneous evaluation using circuits coupled to expansion measuring strips applied to opposite sides of crown of rail

摘要

The train wheel loading measurement system allows the standing force and the side force acting on the wheel to be measured simultaneously, using expansion measuring strips applied symmetrically to the opposite sides of the rail. These are coupled to respective evaluation circuits (A,A') for the strips. The outputs of the evaluation circuits are fed to an additional and substraction stage (AS) which adds the output signals for one force components (FA) and substracts the output signals for the other force component (FS). Pref. four expansion measuring strips (1...4; 1'...4') in a bridge configuration are applied to each side of the rail. USE - Measuring wheel load of high-speed train wheel.
