Coupler assembly and rail vehicle with the same

Abstract

The invention discloses a draw gear assembly and a rail vehicle with the draw gear assembly. The draw gear assembly comprises a draw gear mounting seat and a draw gear fixedly arranged on the draw gear mounting seat, and further comprises guide components arranged on two sides of the draw gear mounting seat, wherein the guide components are provided with longitudinally tilting guide sliding chutes; the front ends of the guide sliding chutes are higher than the rear ends; and sliding blocks which are in sliding fit with the guide sliding chutes in the corresponding sides are fixedly arranged on two sides of the draw gear mounting seat, and are configured as follows: under an initial state, the draw gear mounting seat is fixedly connected with the guide components, and the sliding blocks are located at the front ends of the guide sliding chutes. The structural design of the draw gear assembly can guarantee a coupling function of the draw gear during normal operation; and when collision occurs, the draw gear can neither invade the upper parts of the guide components to damage upper equipment nor fall onto a rail to increase derailing risk in the backing off and energy absorption processes, so that the passive safety of rail vehicle collision can be improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a coupler assembly and a rail vehicle with the coupler assembly. Background technique [0002] As the speed of high-speed rail increases, people pay more and more attention to passive safety. [0003] At present, in order to reduce the air resistance and improve the starting performance of the train, the head of the train usually adopts a streamlined tip shuttle design; although this design reduces the running resistance of the train and increases the speed of the train, the space at the front end of the train is narrow and can only accommodate In the lower coupler part, it is no longer possible to arrange a large energy-absorbing mechanism. [0004] When two high-speed trains collide, the coupler is the first to be impacted. Although the coupler can be set as an energy-absorbing coupler, its energy absorption is limited and cannot completely absorb the energy generated by...

Problems solved by technology

[0003] At present, in order to reduce the air resistance and improve the starting performance of the train, the head of the train usually adopts a streamlined tip shuttle design; although this design reduces the running resistance of the train and increases the speed of the train, the space at the front end of the train is narrow and can only accommodate In the lower coupler part, it is no longer possible to arrange a large energy-absorbing mechanism

[0004] When two high-speed trains collide, the coupler is the first to be impacted. Although the coupler can be set as an energy-absorbing coupler, its energy absorption is limited and cannot completely absorb the energy generated by the collision of the train. During the process, the hidden danger of intruding into the upper part of the guide part and damaging the upper equipment, or falling onto the track increases the risk of derailment

[0005] Therefore, how to improve the existing coupler structure to fully ensure the function of the energy-absorbing module at the rear end of the coupler, and to avoid invading the upper part and destroying the upper equipment during the backward process of the impacted coupler, or falling onto the track to increase the risk of derailment is a technology in the art Technical problems that personnel currently need to solve
