RAIL VEHICLE-TO-BOGIE CONNECTION UNIT Russian patent published in 1996 - IPC

FIELD: railway transport. SUBSTANCE: unit has thrust bearing 8 in form of support plate with cylinder secured on body frame 3. Cylinder accommodates rod 5 hinge-coupled with support 7 engaging with bogie thrust bearing 8. Bevels made in lower portion of support 7 form flat for engagement of support 7 with thrust bearing 8 in direction square to longitudinal axis of bogie. Width of flat is defined by value of maximum tolerable axial load and designed load and by coefficient of nonuniform distribution of loads between wheelsets. Height of bevel in lower portion of support 7 is defined by angle of tilting between plane of frame thrust bearing 8 and plane of bogie thrust bearing 8. Support is fixed from turning relative to bogie thrust bearing 8 by means of L-shaped fasteners. Bogie turns relative to body over plane between frame step bearing 8 and upper surface of support 7. EFFECT: optimization of axial loads of bogie wheelsets by reducing arm of action of load force. 2 cl, 6 dwg
