113 structure of bogie mounting base of train head vehicle 1 is by crossbeam 1131, bogie installation proximate matter 1132, traction seat
1133 groups are welded.This structure is hollow structure, and tire half is in vehicle body bottom frame 11 in the following, half is on vehicle body bottom frame 11.
Entire bodywork height can be reduced in this way, reduces the center of gravity of vehicle, increase the stability of car body.Bogie traction seat 1133 is compared
The pillow pulling of other vehicles is slow to increase intermediate traction seat 1133.It turns in car body or when by lateral force, intermediate traction seat
1133 can share lateral force, reduce the relative displacement between mounting base and car body；It increases the stability of car body and vehicle can be reduced
Turning radius is suitable for complicated urban air traffic.
1 side wall of train head vehicle, 12 structure.Side wall 12 is the left and right sides, and both sides side wall 12 is symmetrical, per side by 3 pieces of side walls
12 board groups are at every block of 12 plate of side wall is made of 12 proximate matter of side wall and door pillar or end column, is opened on four blocks of 12 plates of side wall later
There is window.12 plate of side wall is connect with chassis 11, headwall 13 and roof 14.
14 structure of roof, roof 14 are made of car roof side-beam, air-conditioning plate and roof proximate matter.Air-conditioning is placed using sunk type.
The placement of air-conditioning sunk type can be such that air-conditioning upper surface is consistent with 14 radian of roof, increase the cleanliness of car body.Sink simultaneously
Its inlet and outlet of formula air-conditioning is closely attached to all with car body, increases leakproofness.Furthermore sunk type air-conditioner drain mouth has been placed on sky
It adjusts following.Air-conditioning waste water and rainwater are entered by air-conditioner drain mouth, and the discharge of 11 lower surface of vehicle body bottom frame is directly passed to by pipeline, is subtracted
Air-conditioning waste water washing away and corroding to 12 lacquer painting of roof 14 and side wall is lacked.
15 structure of headstock of train head vehicle 1.15 structural outer of headstock is wrapped up by fiberglass head-shield, streamlined, meets air
Demanding kinetics.Inside is skeleton framework, and installation point is provided for fiberglass.The entire design of headstock 15 meets energy when unexpected collide
Amount absorbs.
This structure hollow transfers in 11 draw bar mounting base of air outlet edge and chassis etc., be by the welding of several blocks of plates and
At, deformed after welding job amount is huge in the later stage is welded to form and welding it is big, it is contemplated that this several place is changed to squeeze in the later stage
Profile structure.
In addition, some section material sections are complex in this structure, extrusion forming is more difficult, and yield rate is relatively low,
Under the premise of meeting rigidity, intensity, it can suitably simplify section structure.
It uses all aluminium alloy vehicle body, vehicle body to may be implemented to weld connection entirely in this structure, increases overall intensity and anticorrosion
Performance.Meanwhile all aluminium alloy vehicle body reduces car body weight, substituting pillow pulling with bogie mounting base 113 delays structure so that car body
The min. turning radius of operation can reach 50m, be suitable for the complicated state of urban air traffic.
