Problems solved by technology

The existing coupler buffer device and pressure collapse energy-absorbing parts can only meet the impact speed of 25km / h, but for the impact speed of 36km / h stipulated in EN15227C-I level, the energy absorption of the existing energy-absorbing parts is insufficient, and the energy-absorbing parts need to be improved. Energy components, increasing their energy absorption

Embodiment Construction

[0024] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0025] Such as figure 1 with figure 2 As shown, a rail vehicle underframe end anti-collision structure includes an anti-climber 1, an energy-absorbing component 2, a stop beam 3 and an end load-bearing frame 4, and the end load-bearing frame 4 is the front end of the vehicle underframe 5 The stop beam 3 is fixed on the front end of the end bearing frame 4, and the anti-climber 1 and the energy-absorbing component 2 are located in front of the stop beam 3 and fixed on the stop beam 3. Arranging the stop beam 3 at the front end of the end bearing frame 4 can effectively limit the deformation in the space in front of the end of the underframe 5 to ensure the driver's escape space.

[0026] The end bearing frame 4 includes side beams 6 on both sides and a traction beam 7 in the middle, and a plurality of beams 8 are arranged laterally between the...

Abstract

The invention relates to an anti-collision structure at the end of a rail vehicle underframe, comprising an anti-climber, an energy-absorbing component, a stop beam and an end load-bearing frame, the stop beam is fixed on the front end of the end load-bearing frame, and the anti-collision The climber and the energy-absorbing component are fixed on the stop beam, and the end bearing frame is fixed on the front end of the chassis. The anti-climber and the energy-absorbing part provided by the invention have relatively large energy-absorbing capacity, so that they can work together with the coupler to absorb the impact energy produced by the impact speed up to 36km / h. Moreover, by arranging the stop beam and setting the stop beam at the front end of the end bearing frame, the deformation is effectively limited in the space in front of the end underframe, ensuring the driver's escape space.

Description

technical field [0001] The invention relates to a rail vehicle, in particular to an anti-collision structure at the end of a rail vehicle underframe, and belongs to the technical field of rail vehicle manufacturing. Background technique [0002] With the development of our country's social economy and the acceleration of people's life rhythm, the status of rail transit in urban traffic is getting higher and higher, and people's requirements for the safety and economy of rail vehicles are also getting higher and higher. The European Union has specially formulated "EN15227 Railway Application-Requirements for Crash Resistance of Railway Vehicle Body", which stipulates that the structure of rail vehicles should be designed reasonably. Sufficient escape space, the C-I class crash requirements in the standard EN15227 stipulate that railway vehicles should be able to withstand impact speeds up to 36km / h. The existing coupler buffer device and pressure collapse energy-absorbing pa...
