Embodiment

[0024] according to figure 1 As shown, the front end of the train with the anti-climbing energy-absorbing device in the present invention comprises a coupler box 2 connected to the front end of the traction beam 1 of the car body, a coupler mounting seat 3, an anti-climbing energy-absorbing device mounting seat 4 and an anti-climbing energy-absorbing device 5.

[0025] Among them, the coupler box 2 is mainly a box-shaped structure welded by the web, the upper cover plate 2-3, the partition plate 2-4 and the bottom plate 2-5. Two webs 2-1, 2-2. The coupler box 2 has a channel for the longitudinal passage of the coupler and the coupler mounting seat 3. The first and second webs 2-1, 2-2 and the coupler mounting seat 3 are respectively provided with rectangular gaps for the coupler to pass through. 1. The top of the second web 2-1, 2-2 is connected with an upper cover 2-3, the first and second web 2-1, 2-2 are connected with a partition 2-4, the first, The bottoms of the secon...

Abstract

The invention relates to a front-end train assembly with an anti-creeping energy-absorbing device which is characterized in that a train coupler box is arranged on the end part of a traction beam and the outer side face of the train coupler box is connected with the anti-creeping energy-absorbing device through an installing base of the anti-creeping energy-absorbing device. If trains with front-end train assemblies provided by the invention suffer from serious collision in running, train couplers of the two trains firstly contact in collision, shock absorbers on the train couplers absorb collision energy, power absorbing elements of the anti-creeping energy-absorbing devices generates rushing creeping to absorb energy, and the anti-creeping energy-absorbing devices can backwards transfer impact force generated by the collision to car coupler boxes. The front end structure provided by the invention solves the problem of creeping in the collision of trains, has the characteristic of low possibility of deformation under impact, and has the functions of receding and eliminating impact force; and therefore, compared with a traditional end beam structure, the front end structure has outstanding substantive characteristics and remarkable progress.

Description

technical field [0001] The invention relates to a front end composition of a train with an anti-climbing energy-absorbing device, which belongs to the field of train body structure design. Background technique [0002] With the development of science and technology and the acceleration of people's life rhythm, the transportation speed of railway passenger cars has been significantly improved. Moreover, the modern railway transportation system is highly electronic, and under the influence of some uncontrollable factors, it is easy to cause failures (such as lightning strikes) and lead to tragedies. Therefore, higher requirements are put forward for the safety design of trains, and people pay more and more attention to the crashworthiness of trains. [0003] The end of the chassis of the existing train is basically only provided with an end beam that is transversely connected to the end of the draw beam, and the end beam is further provided with a coupler connection and a buf...
