Energy absorption structure, cowcatcher device and railway vehicle

Abstract

The invention discloses an energy absorption structure, a cowcatcher device and a railway vehicle, wherein the energy absorption structure comprises a U-shaped frame and energy absorption pipes which are made of composite materials, and comprises an energy absorption pipe front seat and an energy absorption pipe rear seat which are made of meta; the energy absorption pipe front seat is fixed on the inner side of the front part of the U-shaped frame, and the two ends of the energy absorption pipe rear seat are respectively fixed with the two tail ends of the U-shaped frame; the energy absorption pipes are fixed between the energy absorption pipe front seat and the energy absorption pipe rear seat; and moreover, the energy absorption pipe front seat and the energy absorption pipe rear seat are both provided with metal bosses, and the energy absorption pipes and the metal bosses are mutually nested and fixed. According to the scheme, the energy absorption requirements of different vehicle types are met by adjusting the number and length of the energy absorption pipes, and the application range is wider; the U-shaped frame made of the composite material serves as a main body, the energy absorption pipe front seat and the energy absorption pipe rear seat are made of metal and serve as a framework, and on the basis of certain structural strength, the weight can be effectively reduced; the metal bosses and the energy absorption pipes are fixed in a nested mode, and reliable installation of the energy absorption pipes made of the composite material is achieved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an energy-absorbing structure, an obstacle remover device and a rail vehicle. Background technique [0002] At present, rail vehicles use special energy-absorbing devices to absorb energy during collisions, thereby providing passive safety for vehicles. However, there are bottlenecks in the design of energy-absorbing structures, and the application is not flexible enough, so it is difficult to further improve the energy-absorbing effect. Contents of the invention [0003] The invention provides an energy-absorbing structure, which includes a U-shaped frame made of composite materials, an energy-absorbing tube, and a front seat of the energy-absorbing tube and a rear seat of the energy-absorbing tube, both of which are made of metal. The front seat of the energy-absorbing tube is fixed on the U The inner side of the front part of the U-shaped frame, the two ends of the rear sea...
