FIELD: transport.SUBSTANCE: invention relates to railway transport, namely, to mounts of brake shoes for railway cars. Mounting assembly is made with possibility to track lateral travel of wheel on axle truck. Wheel flange is made with possibility to press one side of brake shoe mounting assembly pushing it along axle and squeezing resilient displacing structure. When a wheel returns to central or neutral position squeezed resilient displacing structure expands and returns brake shoe mounting assembly to its initial or neutral position. Also, resilient displacing structure minimises lateral travel of brake shoe mounting assembly towards wheel taper under normal braking loads thus preventing shoe slipping off. Resilient displacing structure can be placed into casing made capable to prevent ingress of contaminants. Railway car braking system contains brake actuator of railway car and brake shoe mounting assembly. Method for installation of brake shoe mounting assembly consists in providing mounting bracket, articulated joint of suspended casing with mounting bracket by means of the first rotary axis, articulated joint of braking shoe holder with opposite sides by means of the second rotary axis, and installation of resilient displacing structure on the second rotary axis.EFFECT: provision of somewhat braking shoe lateral travel to track wheel lateral travel on railway car truck frame.20 cl, 11 dwg |
