Coupler

Abstract

The invention provides a coupler, and belongs to the technical field of carriage connection. The coupler is fixed on a traction beam, and comprises a coupler body and a rod body extending from the coupler body, wherein the coupler body is positioned outside the traction beam, and the coupler body is positioned inside the traction beam; a mounting 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 traction beam, the axial directions of the first mounting holes are parallel to the transverse direction of the traction beam, and the mounting seat is positioned in the traction beam and is connected with the traction beam through bolts inserted in the first mounting holes; one end of a buffer device passes through the first through hole and is connected with the rod body, and the other end of the buffer device is abutted against the mounting seat. The coupler can reduce the potential safety hazard of the carriage, save the installation space of a retractor, and also prevent the carriage from shaking when just subjected to the traction force of the retractor.

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
