Energy-absorbing anti-climbing device for rail transit vehicles

Abstract

The invention discloses an energy absorbing anti-creep device for track traffic vehicles, which can effectively absorb the impact energy generated during collision of the vehicles. The energy absorbing anti-creep device for the track traffic vehicles comprises an anti-creep fluted plate, an anti-bending guide rod, an extrusion expansion crushing pipe and a mounting seat; a guide hole is formed in the mounting seat; a cutting chip is arranged around the guide hole; a cutting sleeve is sleeved on the anti-bending guide rod and is positioned between the anti-creep fluted plate and the cutting chip. The cutting sleeve of the energy absorbing anti-creep device is cut by the cutting chip in the retreating process, and extrusion, friction, failing and damaging effects are generated in the cutting process, so the impact kinetic energy is stably fast absorbed; meanwhile, the extrusion expansion crushing pipe also achieves the energy absorbing action, the energy absorbing modes are diversified, and the energy absorbing capacity of the energy absorbing elements is large and the impact energy generated during the collision of the vehicles can be effectively absorbed. The energy absorbing anti-creep device for the track traffic vehicles is suitable for being applied in the technical field of passive safety of the track traffic vehicles.

Description

technical field [0001] The invention belongs to the technical field of passive safety of rail transit vehicles, and in particular relates to an energy-absorbing anti-climbing device for rail transit vehicles. Background technique [0002] The energy-absorbing anti-climbing device used for rail transit vehicles is to minimize the loss of vehicle collision accidents caused by unavoidable situations. Its working principle is as follows: During the collision process of the rail transit vehicle, when the coupler reaches the energy absorption capacity and shears off, the anti-climbing tooth plates at the end of the vehicle start to contact and mesh with each other to prevent the vehicle from climbing. At the same time, the designed The energy-absorbing tube absorbs kinetic energy by crushing deformation. However, the existing energy-absorbing and anti-climbing devices used for rail transit vehicles have a single energy-absorbing method, which will cause excessive peak force and c...
