Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] An integrated buffer crushing device, which is installed between the coupler coupling system 1 and the installation suspension system 2 of the hook buffer device. The device includes a buffer 3 and a crushing pipe 4. The inside of collapse tube 4.

[0016] The above-mentioned crushing tube 4 includes a deforming tube 5 and a pressurizing tube 6 connected with the deforming tube 5. The shell of the buffer 3 is set in the deforming tube 5, and its end is connected with the pressurizing tube 6. The other end is connected with a flange interface 7 .

[0017] When the crushing tube 4 works, in order to deform the deforming tube 5 , the buffer housing is provided with a limiting block 8 for limiting the crushing tube, and the limiting block 8 is arranged at the inlet end of the deforming tube 5 .

[0018] During the deformation process of the deformation tube 3, in ...

Abstract

The invention relates to an integrated crushing buffer device, which is arranged between a coupler coupling system and a mounting and hanging system of a coupler draft device and comprises a buffer and a crushing pipe, wherein a shell of the buffer is sleeved in the crushing pipe. The integrated crushing buffer device has a simple and reliable structure; the buffer is sleeved in the crushing pipe; a parallel arrangement mode of the buffer and the crushing pipe is adopted; the longitudinal space is saved; and both the buffer and the crushing pipe have larger ranges, i.e., higher energy absorbing capacity, without increasing the length of the coupler.

Description

technical field [0001] The invention relates to a rail vehicle protection device, in particular to a cushioning and crushing device for absorbing impact energy between vehicles during normal train operation, or for absorbing impact energy when trains collide abnormally. Background technique [0002] During the operation of rail vehicles, in order to improve the safety and comfort of vehicles and avoid unexpected collisions during operation, the couplers connected to the vehicle body need to be equipped with buffers and crush tubes. Among them, the buffer is used to absorb the impact energy between the vehicles during the normal operation of the train, improve the longitudinal impulse performance of the vehicle, and improve the safety and comfort of the vehicle; the crush tube is used to absorb the impact energy when the train is abnormally collided, and is used to protect the car body equipment and passengers. personnel safety. At present, the existing buffer 3' and the cru...
