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 EMUs vehicle generally uses coupler and draft gear at present.But have many areas smaller
Country, it is less high to EMUs rate request, and emphasis considers to run on the less circuit of radius of turn, therefore the external car in part
Operator specifies EMUs to use articulated bogie.
Foreign countries are French TGV called and AGV bullet trains using the most successful case of articulated bogie, and its bogie is 2 points
Suspension is without bolster radial type, and vehicle has individual feature to be that floor level is higher.But Some vehicles operator considers HOP ON-CHOP OFF,
It is required that vehicle sets center-aisle, it is highly relatively low, can only be solved by designing middle recessed structure, be unfavorable for car body
Carrying and power transmission, add the design difficulty of car body.
At home, less are studied to radial type EMUs, and is connected on low floor vehicle and light rail vehicle using radial type
Connect more, and be usually based on bolster articulated bogie, to be had using the vehicle of this bogie and pass through small labyrinth radius
The characteristics of ability is strong, but axle weight is smaller, typically at 10 tons or so.
To solve the axle weight demand of EMUs, it can be solved using a kind of non-bolster articulated bogie, that is, use and be hinged
Formula draw-gear, passes through 4 air spring bearing bodies.But at the same time, in the past traditional vehicle body bottom frame structure can not meet this
The installation connection of novel steering frame is planted, therefore is badly in need of a kind of new car body underframe end portion structure of exploitation.
