Connection of system for changing track gauge of freight wagons test stand

The test stand for proper operation shall have a equipped of auxiliary systems. One of them is the track gauge adjustment system. The original gauge adjustment mechanism revealed shortcomings caused by the wear in operation. The new solution of track gauge setup on the test stand consists of hydraulic circuit design, construction, control and subsequent verification of reliability and proper operation. For proper operation and accurate results, the test bench was fitted with an apparatus for centering the rotating rail. The measuring apparatus shows what gauge is set on the rotating rails and in which position the individual rail are located. Measurements have been made to verify the functionality of the system and to help set the correct function of the hydraulic cylinders. By examining the transverse forces at unloaded rotating rails, the proper function of the hydraulic system has been verified. After load of the rotating rails with wheelset was monitored by the process of the guiding (transverse), longitudinal and wheeled (vertical) forces.
