FIELD: transport.SUBSTANCE: invention relates to railway transport. Coupler 1 comprises thrust plate 10 to be jointed with car body that has through hole 11 receiving con rod end part 3 extending from car body side. Coupler 1 comprises also draw device arranged on said end part 3 that includes front damper plate 12 attached to con rod 2 ahead of thrust plate 10 in lengthwise direction L and rear damper plate 14. Rear damper plate 14 is attached to con rod 2 behind thrust plate 10 along distance L of said con rod. Draw device comprises extra element 20 of front damper made from elastic material and arranged between plate 10 and plate 12, and rear damper element 30 made from elastic material and arranged between plate 10 and plate 14. Front damper element 20 and/or rear damper element 30 interact with plate 10 to transmit rotation transferred from con rod 2 to thrust plate 20 are transmitted with no slippage. Said front damper element 20 comprises grooves 21.1-21.8 made on its edges. Thrust plate 10 comprises extending sections 16.1-16.4 on its front surface A1 opposite element 20 shaped to interact with some of said grooves 21.1-21.8.EFFECT: simplified design.22 cl, 5 dwg |
