Vehicle anti-creeping energy absorption device

Abstract

The invention provides a vehicle anti-creeping energy absorption device. Vehicle coupler mounting parts are fixed to the two ends of an anti-creeping edge beam arranged in an arch shape; movable mounting grooves are formed in the end faces of the outer sides of the anti-climbing edge beams, and the movable anti-climbing beams are slidably connected to the movable mounting grooves through sliding rails; energy-absorbing telescopic assemblies are placed in the movable mounting grooves. Therefore, in a vehicle collision process, the energy-absorbing telescopic assemblies and the anti-creeping edge beams arranged in the arch shape in the vehicle anti-creeping energy absorption device construct deformation composite energy absorption, the energy absorption capacity of the vehicle anti-creepingenergy absorption device is greatly increased, and collision kinetic energy in the vehicle collision process can be effectively absorbed, so that too large deceleration transmitted to passengers can be avoided, and loss caused by collision of vehicles can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a vehicle anti-climbing energy-absorbing device. Background technique [0002] The anti-climbing energy-absorbing structure devices of the existing rail transit vehicles are generally designed according to European standards, but the existing European standards have a single structure for the anti-climbing energy-absorbing structures, resulting in energy absorption when the rail transit vehicles collide Components are affected by vertical bending deformation, and the energy absorption effect is significantly reduced, resulting in excessive deceleration transmitted to passengers and excessive loss in the event of a vehicle collision. Contents of the invention [0003] In order to solve the above problems, the present invention provides a vehicle anti-climbing energy-absorbing device, which overcomes the above technical problems. [0004] In order to achieve the above obje...
