Cutting energy absorber that passenger train was used

The utility model discloses a cutting energy absorber that passenger train was used, including integral key shaft, spline housing, fixed cover and baffle, install to the adaptation ground interferenceformula of integral key shaft in the spline housing, the spline housing activity is nested installs in the fixed cover, the baffle is fixed to be installed the tail end of fixed cover, enclose arc rod looks fixed connection before the tail end of integral key shaft and the passenger train, the fixed stand looks fixed connection who turns to the rack with the passenger train that overlaps. The utility model discloses can guarantee that steering column installation rack collides the in -process in the front and can absorb partly energy (promptly: the partial kinetic energy that produces the collision change into heat energy that integral key shaft cutting spline housing in -process produced and deformation can) and the energy -absorbing steady, can strengthen the rigidity and the intensitythat turn to the rack body
