METHOD FOR DISASSEMBLY OF THE FASTENING ASSEMBLY OF THE BRAKE SHOE OF THE TRIANGEL Russian patent published in 2023 - IPC B61H13/34 

FIELD: railway transport.

SUBSTANCE: invention relates to the field of railway transport. When disassembling the mounting assembly of the triangular brake shoe, the guide roller 12 is screwed into the threaded hole of the triangular string 18 by means of a threaded protrusion 13 with a metric thread Μ10. A central bushing 9 is installed on the guide roller until the wedge ring 11 touches the central bushing. By rotating the handle 5 of the screw 4, the resilient element 16 is compressed, acting with the fifth screw 6 on the central sleeve, which has a groove 14 to prevent incorrect relative positioning of the heel and the central sleeve, while the central sleeve has an internal hole to ensure tolerance with the guide roller. The compressive force is transmitted from the heel through the central sleeve to the wedge ring and to the elastic element, and to extract crackers 17, 3-4 turns of the screw are required. Two released biscuits are removed, by rotating the screw handle, the elastic element is unclenched. By rotating the screw handle, the heel and the central sleeve are released from the interaction. The squeeze device is removed from the triangel frame, the central sleeve and the guide roller is unscrewed from the triangel string. The wedge ring is removed, the elastic element is removed, the tip of the triangle 20 is removed, the shoe of the triangle 19 is removed.

EFFECT: increasing the operational reliability of the squeeze device and ensuring the safety of work.
