Rail vehicles and their coupler boxes

Abstract

The invention discloses a coupler box of a rail vehicle, comprises a mounting seat fixedly mounted on the bottom of the vehicle body and a box body connected with a hook retarding device, A tank bodyis connected with that mounting seat through a constant-force connector, As that hook retard device pushes the box body to move inward during the collision, the fixed-force connector is used for beingpulled off, so that the box body can be separated from the mounting base, the bottom of the car body is provided with a slide groove extending in the longitudinal direction thereof, a slider installed in the slide groove is connected to the top of the box body, the slider can be moved in the extending direction of the slide groove, and the slider groove can prevent the slider from falling. Ordered energy absorption, The structure of the coupler box is simple, easy to realize, meets the collision standard, ensures the personal safety of passengers, improves the crashworthiness of the rail vehicle with coupler retarder, solves the problem that the installation structure of the coupler retarder will not be invalidated or the failure difficulty prevents the next energy absorption device fromtriggering and absorbing energy, and improves the safety of the equipment. The invention also provides a rail vehicle comprising the above-mentioned 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.
