Rail vehicles and their coupler boxes

Abstract

The invention discloses a coupler box of a rail vehicle, includes a fixed part fixedly mounted on the vehicle body and a movable part connected with the hook retarder, wherein the movable part is connected with the inner end of the fixed part through a fixed force connector, and the fixed force connector is used for being pulled off during the inward movement of the hook retarder when the hook retarder pushes the movable part so as to separate the movable part from the fixed part. The crashworthiness of rail vehicles with hook-and-retard device is improved to solve the problem that the installation structure of hook-and-retard device will not fail or the difficulty of failure will hinder the triggering and energy absorption of the next energy absorption device when the train collides, andto improve the safety of the equipment. The invention also discloses a rail vehicle comprising the coupler box.

Description

technical field [0001] The invention relates to the field of rail vehicles, in particular to a coupler box of a rail vehicle. Furthermore, the invention also relates to a rail vehicle comprising the above-mentioned coupler box. Background technique [0002] With the development of rail technology, people pay more and more attention to the passive safety of car body. The energy-absorbing structure of the collision-resistant locomotive body mainly includes multi-level energy-absorbing structures such as the hook buffer device and the end structure of the car body. It can absorb energy in an orderly and controllable manner; that is, when two vehicles collide, the hook buffer device moves backward to absorb energy. The energy absorption is triggered by the energy absorbing part of the next stage. [0003] However, the coupler box of this type of coupler buffer device currently has a short coupler length and high strength. When a train collides, after the energy absorption of ...

Problems solved by technology

[0003] However, the coupler box of this type of coupler buffer device currently has a short coupler length and a high strength. When a train collides, after the energy absorption of the coupler buffer device ends, the installation structure of the coupler buffer device will not fail or fail. After the energy absorption is completed, the hook slowing device will prevent the contact of the next-level energy-absorbing device, so that the next-level energy-absorbing device cannot trigger the energy-absorbing device

[0004] Therefore, in order to improve the locomotive crash resistance performance of the coupler buffer device with coupler tail frame, it is necessary to solve the problem that the installation structure of the coupler buffer device will not fail or fail to be difficult when the coupler box collides with a train, preventing the next-level energy absorbing device from triggering energy absorption.
