Moreover, it is fixed between cavity 22 and casing 21 by connecting slideway 221 and the screw 25 of sliding slot 211.So
Setting, when train collides, two vehicle casings 21 contact first, and after casing 21 cuts screw 25, casing 21 can
It is slided in cavity 22, in this way, collision energy is absorbed by cutting spiral shell 25, here, the fixation between cavity 22 and casing 21
Mode can also use other fixed forms such as welding or pin joint, be not particularly limited to its fixed position, as long as can incite somebody to action
Cavity 22 and the realization of casing 21 pre-fix and can sever bearing in train knockout process, play buffering energy-absorbing function
.
In addition to this, two energy-absorbing modules 4 are symmetrically arranged in the top of hitch 3,3 top setting energy-absorbing module 4 of hitch, two
Vehicle collide when contact point it is more top can prevent train occur headstock move upwards climb vehicle phenomenon.The energy-absorbing module 4 has
Have and 1 fixed square tube 42 of car body, car body 1 are provided with the receiving storehouse 43 of the opposite sliding with square tube 42, the front end of square tube 42 protrudes
Storehouse 43 is accommodated, the rear end of square tube 42 is not contacted with the rear end for accommodating storehouse 43, is accommodated and is passed through fastener 423 between storehouse 43 and square tube 42
It is fixed, area of section is provided between square tube 42 and receiving storehouse 43 no more than the honeycomb aluminum 41 for accommodating 43 inner section area of storehouse.Work as row
When vehicle collides, which can realize two-stage energy-absorbing, that is, square tube 42 cuts fastener 423 with storehouse 43 is accommodated
It is disconnected, realize that first-level buffer energy-absorbing, square tube 42 squeeze honeycomb aluminum 41 along the receiving storehouse 43 and realize level 2 buffering energy-absorbing, here, tightly
Firmware 423 can be the connector that bolt, screw either pin etc. can play fixed function.Above-mentioned receiving storehouse 43 passes through bolt
432 connect with car body 1.
4 front end face of energy-absorbing module is flushed with 2 front end face of energy absorption device, in this manner it is ensured that in train in collision process,
Energy-absorbing module 4 and energy absorption device 2 collide simultaneously, and such making contact point is more, and it is smaller that vehicle probability occurs climbing in train, has ensured and has touched
Hit safety.
Further, there are the inner wall for accommodating storehouse 43 two symmetrical grooves 431, the groove 431 to be longitudinally extended along inner wall, side
Pipe 42 is provided with protruding portion compatible with groove 431 421.So set, facilitating square tube 42 along 431 institute of groove for accommodating storehouse 43
The trace compression honeycomb aluminum 41 of restriction, the phenomenon that preventing train derailment.In addition, in square tube 42 and 41 contact site of honeycomb aluminum be provided with
Protrusion 422, honeycomb aluminum 41 are provided with the recessed portion 411 being adapted to interior protuberance 422, and above-mentioned setting can ensure 41 edge of honeycomb aluminum
Square tube 42 is slided, and compressed path of the honeycomb aluminum 41 in extrusion process used for forming can be limited.
Receiving is provided with connecting plate 44 between storehouse 43 between receiving storehouse 43 and car body 1, ensures the intensity for accommodating storehouse 43, real
