Semi-permanent car coupler for light rail

Abstract

The invention relates to a semi-permanent car coupler for a light rail, which comprises an end with a buffer and an end without a buffer, wherein the end with the buffer comprises the buffer, a joint bearing connected with the buffer and an installing seat, and the joint bearing is connected with the installing seat through a coupler yoke key; the end without the buffer comprises a left pull ring, a joint bearing connected with the left pull ring and an installing seat, and the joint bearing is connected with the installing seat through a coupler yoke key; the buffer is a double-acting buffer which comprises a shell, a left end cover, a right pull ring, elastomers, a central axis and a middle clapboard, wherein the central axis passes through the center of the left end cover and the right pull ring and is in slide contact with the left end cover and the right pull ring; one end of the central axis extends out of the left end cover; the middle clapboard is fixedly arranged on the central axis and divides the inside of the shell into two elastomer containing cavities, and the elastomers are positioned in the two elastomer containing cavities; and a convex plate is arranged at the other end of the left pull ring, a convex plate is also arranged at one end of the central axis extending out of the left end cover, and the two convex plates are connected through a connecting ring.

Description

technical field [0001] The invention relates to a railway vehicle coupler, in particular to a semi-permanent coupler with a buffer for a light rail. Background technique [0002] With the improvement of people's living standards, urban traffic has become increasingly congested. In order to solve the current situation of urban traffic congestion, with the development of railway transportation, light rail has been gradually built in major cities. Some semi-permanent couplers with or without buffers are mostly fixed on the car body directly through the mounting seat. When loading, maintenance or other situations need to be disassembled, the mounting seat or coupler pin must be disassembled, which is inconvenient to disassemble. . At the same time, it is necessary to design a buffer that is well integrated with the light rail. Contents of the invention [0003] The object of the present invention is to aim at the shortcomings of the prior art, and provide a semi-permanent c...
