Description

Technical Field

[0001] The utility model relates to the technical field of rail vehicle energy absorption, in particular to a front end energy absorption structure of a rail vehicle body underframe. Background Art

[0002] Rail vehicles are a general term that refers to vehicles with dedicated tracks, including traditional trains. In addition, EMUs, subway vehicles, light rail vehicles and maglev vehicles also fall into the category of rail vehicles. In order to improve the collision resistance of rail vehicles, energy-absorbing structures are generally installed at the front end of the vehicle's body frame. However, existing energy-absorbing structures have certain inconveniences when used.

[0003] A rail vehicle and a front-end buffer energy absorption device thereof are disclosed in the Chinese utility model patent application No.: CN201820004266.7, including an anti-collision beam, a mounting seat for fixing the front-end beam of the vehicle body chassis of the rail vehicle, and a buffer energy absorption component arranged between the anti-collision beam and the mounting seat; the buffer energy absorption component includes a spring plate, a buffer sleeve and a buffer column adapted to the buffer sleeve; one end of the spring plate is fixedly connected to the anti-collision beam, and the other end of the spring plate is fixedly connected to the mounting seat; one end of the buffer column is fixed to the mounting seat, and the other end of the buffer column is provided with a protrusion, and the head of the protrusion is embedded in a port at one end of the buffer sleeve, The other end of the buffer sleeve is arranged on the anti-collision beam, and when the extrusion pressure between the protrusion and the buffer sleeve reaches a preset pressure value, the protrusion can expand the buffer sleeve. The overall structure of the above-mentioned device is simple, which not only reduces the production cost but also ensures the service life of the device. In addition, the utility model also discloses a rail vehicle, but the energy absorption method of the buffer energy absorption device is relatively single when in use, and the energy absorption effect of the main energy absorption structure and the anti-climbing energy absorption structure cannot be guaranteed. Moreover, the buffer energy absorption device is not easy to disassemble and assemble when in use, and it is not easy to replace it after collision damage. For this reason, we propose a front end energy absorption structure of a rail vehicle body chassis. Utility Model Content
