STAND FOR DETERMINING THE DYNAMIC LOADS ARISING IN THE WHEEL PAIRS OF A FREIGHT CAR BOGIE WHEN PASSING CURVED TRACK SECTIONS

摘要

FIELD: vehicles testing.;SUBSTANCE: invention relates to the field of vehicles testing, in particular to stands for determining the dynamic loads arising in the wheelsets of a freight car bogie when passing curved track sections. The stand contains a base, nodes that ensure the rotation of wheelsets, load nodes of the bogie and a crane-beam. The base contains two rigidly connected beams. The ends of one beam rest on supports. The ends of the second are on the lifting mechanism. The mechanism contains two lever assemblies connected by a longitudinal thrust. Longitudinal movement of the rod changes the position of the inclined levers of the link assemblies, providing the lifting of the second beam and the movable rail.;EFFECT: invention makes it possible to determine dynamic loads when passing curved sections.;1 cl, 2 dwg
