The invention discloses an expansion cutting type railway vehicle energy absorption anti-creeper, which comprises a mounting seat, an energy absorption expansion pipe, a cutting tool and anti-creepingteeth, wherein an expansion head is arranged on the mounting seat; one end of the energy absorption expansion pipe is connected to the expansion head in a sleeving mode; the cutting tool is installedon the mounting seat and located on the periphery of the expansion head, and a cutting edge of the cutting tool faces the end of the energy absorption expansion pipe and extends in the radial direction of the energy absorption expansion pipe; the anti-creeping teeth are installed at the end, away from the expansion head, of the energy absorption expansion pipe. According to the expansion cuttingtype railway vehicle energy absorption anti-creeper, the viscous effect between the expansion head and the energy absorption expansion pipe can be avoided, and the situations of cutter melting and cutter breaking of a cutting tool are avoided.
Description
technical field [0001] The invention relates to the technical field of energy-absorbing devices for rail vehicles, in particular to an expansion-cutting energy-absorbing anti-climber for rail vehicles. Background technique [0002] With a series of technical advantages such as fast speed, large transport capacity, low energy consumption, and light pollution, rail transit is playing an increasingly important role in the economic society of various countries. At present, my country has become the country with the longest operating mileage, the highest operating speed and the largest scale of high-speed railways in the world. [0003] However, with the development of rail transit, its operation safety has also attracted widespread attention from all walks of life. In order to improve the passive safety of train operation, the two ends of rail vehicles are usually designed as deformable energy-absorbing areas, and various energy-absorbing elements are installed inside. As an i...
