coupler

Abstract

The invention provides a vehicle coupler, which belongs to the technical field of carriage connection. The vehicle coupler is fixed on a traction beam. The pull hook includes a hook body and a rod body extended from the hook body, and the hook body is located outside the traction beam, and the hook body is located inside the traction beam; The seat is provided with a first through hole and a plurality of first mounting holes, the axial direction of the first through hole is parallel to the longitudinal direction of the drawing beam, the axial direction of the first mounting hole is parallel to the transverse direction of the drawing beam, and the mounting seat is located in the drawing beam. And it is connected with the traction beam through the bolt inserted in the first installation hole; one end of the buffer device is connected with the rod body through the first through hole, and the other end of the buffer device abuts against the mounting seat. The vehicle coupler provided by the invention can reduce the potential safety hazard of the carriage and save the installation space of the draw hook, and at the same time, avoid the shaking of the carriage when it just receives the traction force of the draw hook.

Description

technical field [0001] The invention relates to the technical field of carriage connection, in particular to a vehicle coupler. Background technique [0002] The coupler is often used for the connection between locomotives and carriages, or between carriages and carriages, to transmit traction and impact force, and to maintain a certain distance between carriages and carriages or between locomotives and carriages. [0003] The existing coupler is often fixed in the draw beam, and the coupler includes a draw hook, a support seat and a slave plate seat, wherein the support seat and the slave plate seat are located in the draw beam, the support seat and the draw beam are fixed by bolts, and the slave plate seat is welded on the traction plate on the beam; and the supporting seat abuts against the secondary plate seat, and the pull hook passes through the secondary plate seat to connect with the supporting seat. [0004] However, the above-mentioned welding seam between the sla...

Problems solved by technology

[0004] However, the above-mentioned welding seam between the slave plate seat and the draw beam is located in the draw beam, and it is difficult to find cracks in the weld seam, which increases the safety hazard of the carriage; The length of the weld required between the beams is longer, which increases the length of the sub-plate seat, so that the use of the support seat and the sub-plate seat to fix the draw hook requires a large installation space; When, it will cause the shaking of the carriage
