Description
Technical field
The present invention relates to a kind of track vehicle body structure, more particularly to a kind of radial type Motor train unit body underframe end knot
Structure.
Background technology
The connection between country's EMU vehicle generally uses coupler and draft gear at present.But there are many national territorial areas smaller
Country, it is less high to EMU rate request, and emphasis considers to run on the smaller circuit of turning radius, therefore the external vehicle in part
Operator specifies EMU that need to use articulated bogie.
Foreign countries are French TGV called and AGV bullet trains using the most successful case of articulated bogie, and bogie is 2 points
Without bolster radial type, it is that floor level is higher that vehicle, which has a feature, for suspension.But Some vehicles operator considers HOP ON-CHOP OFF,
It is required that intermediate channel is arranged in vehicle, height is relatively low, can only be solved by designing intermediate recessed structure, be unfavorable for car body
Carrying and power transmission, increase the design difficulty of car body.
At home, less to radial type EMU research, and connected using radial type on low floor vehicle and light rail vehicle
Connect it is more, and be usually based on bolster articulated bogie, using this bogie vehicle have pass through small labyrinth radius
The strong feature of ability, but axis weight is smaller, generally at 10 tons or so.
To solve the axis weight demand of EMU, can be solved using a kind of non-bolster articulated bogie, i.e., using hinged
Formula draft gear passes through 4 air spring bearing bodies.But at the same time, previous traditional vehicle body bottom frame structure cannot be satisfied this
The installation connection of kind novel steering frame, therefore be badly in need of developing a kind of novel car body underframe end portion structure.
