Railway vehicle having a shock absorbing device

摘要

The invention provides a shock absorbing device capable of starting and promoting crushing of energy absorbing members during elastic deformation of the energy absorbing members receiving compressive load immediately after collision, so as to reduce the peak load during collision and reduce the impact force or acceleration operating on passengers and crew. A railway car has a shock absorbing device including an energy absorber 100 for absorbing collision energy by crushing during collision placed at an end of an underframe. Projections 103 formed at a leading end portion 102 of the energy absorber 100 and a pipe body 110 as trigger member are provided as a trigger mechanism for starting and promoting crushing of the energy absorber 100 when the energy absorber 100 receives compressive load immediately after collision and deforms elastically. The operation of the trigger mechanism enables the energy absorber 100 to start crushing while being elastically deformed, so as to prevent the further progression of elastic deformation causing increase of the peak load during collision.
