Energy absorption device and rail vehicle with energy absorption device

Abstract

The invention provides an energy absorption device arranged at the front end of a train. The energy absorption device comprises a train coupler seat, a support, a pressure feeding tube, a train coupler, a guiding component, energy absorption elements and an anti-climbing assembly, wherein the support is fixedly arranged at the front end of the train; the pressure feeding tube is fixed at the train coupler seat; a train coupler connecting end is mounted in the pressure feeding tube in an inserted manner, and can slide relative to the pressure feeding tube; one end of the guiding component is fixed with the train coupler seat; the other end of the guiding component is mounted at the support in an inserted manner, and can slide relative to the support; the guiding component can limit the swing of the pressure feeding tube; the energy absorption elements are arranged between the train coupler seat and the support; the anti-climbing assembly is fixedly arranged on the support, and can be compressed. According to the energy absorption device disclosed by the invention, the energy generated by collision is absorbed by a manner that various energy absorption assemblies are arranged in a limited space; besides, the displacement perpendicular to the self direction, of the train, is limited by the guiding component and the anti-climbing assembly, so that train climbing and derailing are avoided.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to an energy absorbing device and a rail vehicle with the energy absorbing device. Background technique [0002] As the speed of the high-speed rail increases, the air resistance on the front part of the train increases as well. In order to reduce air resistance and improve the aerodynamic performance of the train, the front part of the high-speed rail adopts a streamlined needle-shuttle design. For this pointed shuttle design, although the running resistance of the train is reduced and the speed of the train is effectively increased, the space in the front section of the train is small, and only the coupler part can be accommodated, so it is impossible to arrange a large-scale energy-absorbing anti-derailment control mechanism. Therefore, when two trains of high-speed trains collide, they are likely to be squeezed in the form of mutual insertion, which will cause the trains ...
