The invention relates to a novel high-energy-absorption alloy elastic energy absorber cylinder of a rail train. The cylinder comprises a shell, a telescopic sleeve shell is screwed in the shell, an inner pipe is fixedly connected in the sleeve shell, and a telescopic piston rod is arranged in the inner pipe in a sliding manner. The outer side of the sleeve shell is in threaded connection with theouter shell with a built-in first spring, so that when the sleeve shell is impacted, the sleeve shell is pushed to retract, extrudes the first spring and rotates and retracts along the shell, and buffering and energy absorption of impact force for the first time are achieved; and when the sleeve shell is pushed to the outer side of the shell, an inserting pipe is inserted into a valve of the innerpipe to be communicated with the inner pipe and the hydraulic cavity, the piston rod goes deep along the inner pipe and injects hydraulic oil into a hydraulic cavity to increase the pressure intensity to recover and store energy for an energy absorber, secondary buffering energy absorption is conducted on longitudinal impact force between trains, the two sections contract gradually, more impact force can be absorbed, and the energy absorption strength of the energy absorber is improved.

    本发明涉及一种轨道列车新型高吸能合金弹性吸能器缸体,包括外壳,所述外壳的内部螺接有可伸缩的套壳,该套壳的内部固定连接有内管,所述内管中滑动设置有伸缩的活塞杆。本发明通过在套壳的外侧螺接有内置第一弹簧的外壳,从而当受到冲击时,套壳被推动回缩,对第一弹簧形成挤压并沿着外壳转动收起,实现第一次对冲击力的缓冲吸能,当套壳被推到外壳靠内侧时,插管插入到内管的阀门中连通内管和液压腔,活塞杆沿着内管深入并将液压油注入到液压腔中进行压强的增加为吸能器的恢复蓄能,完成对列车间纵向的冲击力进行第二次的缓冲吸能,两段逐步的收缩,可以吸收更多的冲击力,增加了吸能器的吸能强度。
