Description
Technical field
The present invention relates to High-sped Trains field, car body and outer hood the installation knot of more particularly to a kind of EMU
Structure.
Background technology
EMU primary structure includes：The parts such as pulling equipment, bogie, car body, wherein car body are the master of train
Form one of main body, car body is both the seating carrier of passenger, be again installation and connect other several parts (such as：Walk
Row portion, brake apparatus, coupling device at car end, vehicle interior decorating apparatus etc.) basis.
Usually, car body is made up of drivers' cab (head car, trailer), chassis, roof, side wall, headwall and each annex of car body,
Wherein headwall is generally positioned between two section compartments, the side wall of the both sides connection body of headwall, end coping outer rim connection car
Top, the bottom connection chassis of headwall.In order to reduce influence of the outside vehicle noise to environment in compartment, between two section compartments also
Windscreen is provided with, windscreen is specifically divided into interior windscreen and outer hood, and wherein outer hood is arranged at outside car body, and the end of outer hood leads to
Frame is crossed to link together with headwall.
The major way of outer hood and headwall is in the prior art：Relevant position sets peace first on the outside of the wallboard of headwall
Seat is filled, then the frame of interior windscreen is welded in mounting seat using welding manner.The connected mode has following defect：
Firstth, when outer hood and mounting seat are welded to connect, because welding heat influences, the end being connected with mounting seat is easily caused
Wall uneven heating is even, and metaboly occurs in welding back-end wall, increases the rigging error of other components of headwall Yu car body, holds
When wall bulk deformation is serious, headwall is caused not to be assembled on car body；
Secondth, the maintenance for being unfavorable for keeping out the wind the later stage outside is welded and fixed to change.
Therefore, how to improve prior art China and foreign countries to keep out the wind mounting structure, the mounting structure is realizing what safety and stability was fixed
Meanwhile be easy to the Fast Installation of interior windscreen and safeguard change, it is those skilled in that art's technical problem urgently to be resolved hurrily.
