Car coupler assembly and rail car with same

Abstract

The invention discloses a car coupler assembly and a rail car with the same. The car coupler assembly comprises a car coupler seat, a folded-collapse tube, a car coupler, a support, a guide component and an energy-absorbing element. The folded-collapse tube is fixedly arranged on the car coupler seat. A pressurization cone of the car coupler is inserted in the folded-collapse tube and can slide relative to the folded-collapse tube. The support is fixedly arranged at the front end of a train. One end of the guide component and the car coupler seat are fixed, and the other end of the guide component is inserted into the support, and swing of the folded-collapse tube can be limited. The energy-absorbing element can be arranged between the car coupler seat and the support. When a collision happens, through the action of impact force, the car coupler is coupled and slides into the folded-collapse tube to achieve primary energy absorption, the car coupler impacts on a stop piece in the guide component, the car coupler and the guide component impact on and shear an energy-absorbing component together to achieve secondary energy absorption, and the car coupler seat compresses the energy-absorbing element to achieve third-level energy absorption. The car coupler slides along the folded-collapse tube all the time, the freedom degree of the folded-collapse tube is limited by the guide component, and the train is prevented from derailing.

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 the high-speed rail increases, the air resistance on the front part of the train increases as well. In order to reduce air resistance and improve the aerodynamic performance of the train, the front part of the high-speed rail adopts a streamlined needle-shuttle design. For this pointed shuttle design, although the running resistance of the train is reduced and the speed of the train is effectively increased, the space in the front section of the train is small, and only the coupler part can be accommodated, so it is impossible to arrange a large-scale energy-absorbing anti-derailment control mechanism. Therefore, when two trains of high-speed trains collide, they are likely to be squeezed in the form of mutual insertion, which will cause the trains to derail and c...
