FIELD: transport engineering; diagnostic facilities. SUBSTANCE: invention relates to means of checking condition of wheelsets of rail vehicles. Proposed stand has friction rollers made in form of supports with vertical axes of rotation and support surfaces in form of rail head and furnished with drives and installed on axial hydrostatic bearings with supply from pumping station on which support signal pickups are mounted. Each support of friction rollers is mounted on slide with "right- hand - left-hand" horizontal displacement hydraulic drive supplied from additional pumping station whose control circuit is coupled with horizontal displacement setting unit. Horizontal displacement hydraulic drive coupled with pumping station can be made with provision of pressure proportional to valve of signal read from magnetic or other data carrier simulating real horizontal loads in curved sections of track and switches. EFFECT: improved accuracy of results of test of wheelset with recording of all actions. 2 cl, 3 dwg |
