Description

Coupling for automatic coupler of railway vehicle Technical Field The utility model belongs to the technical field of rail trains, and particularly relates to a coupler for an automatic coupler of a rail vehicle. Background In an automated connection system for rail vehicles, couplers play a critical role with couplings. With the continuous development of rail traffic, automation, reliability and efficiency are the main requirements of vehicle connection systems. However, the existing coupling designs for couplers still have some drawbacks during use. In particular, during operation of the vehicle, forces from multiple directions need to be applied between the connecting parts, which places higher demands on the structural strength and stability of the coupling. In addition, the existing coupling is complex in structure, and the precise matching of a plurality of parts is involved in the assembly process, so that the assembly process is difficult, errors are easy to occur, and the overall performance is influenced. Due to the limitations of manufacturing tolerance, material nonuniformity, assembly process and other factors, the coupler is often slightly dislocated during assembly, and the dislocating phenomenon mainly results from accumulation of machining errors, so that all parts cannot be completely aligned during assembly, thereby influencing normal operation of the coupler, and particularly, under the condition of environmental temperature change or unsatisfactory assembly conditions, the errors are more remarkable, so that the connection stability of a hook system is reduced, and the coupling or uncoupling of the coupler is not facilitated. Disclosure of utility model The present utility model is directed to a coupling for an automated coupler for a railway vehicle that addresses at least one of the problems and deficiencies set forth in the background above. The utility model provides an automatic coupler for coupler of rail vehicle, including the mount pad, the mount pad both sides are provided with the connecting seat, two be provided with first bearing plate and second bearing plate on the connecting seat respectively, all rotate on first bearing plate and the second bearing plate and be connected with slide bearing, two be provided with the coupler lock round pin axle between the slide bearing, one side fixedly connected with first jack catch of first bearing plate is kept away from to the coupler lock round pin axle, the joint has the second jack catch on the first jack catch, the second jack catch rotates to be connected in the bearing frame, bearing frame fixed connection is on the second connecting seat, one side fixedly connected with bulb coupling assembling of first jack catch is kept away from to the second jack catch.
