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.
本发明公开了一种膨胀切削式轨道车辆吸能防爬器,包括:安装座,安装座上设有膨胀头;吸能膨胀管,吸能膨胀管的一端套接在膨胀头上;切削刀具,安装在安装座上且位于膨胀头的外周,切削刀具的刀刃朝向吸能膨胀管的端部且沿吸能膨胀管的径向延伸;防爬齿,安装在吸能膨胀管远离膨胀头的一端。该膨胀切削式轨道车辆吸能防爬器能够避免膨胀头与吸能膨胀管发生粘滞效应、避免切削刀具出现熔刀、断刀的情况。
