Abstract
The utility model discloses a sidewall structure of a subway train body, which comprises a series of large sidewalls and small sidewalls. The large sidewalls and the small sidewalls cling together, each large sidewall and each small sidewall respectively comprises columns and sidewall plates, the upper end of each large sidewall and each small sidewall is respectively welded with the top cover of a train body, and the lower end of each large sidewall and each small sidewall is respectively welded with the base frame of the train body. Therefore, the utility model provides a simple sidewall assembly process for flexible manufacture of the sidewall, eliminates the original sidewall synthesis process, and saves a large amount of time, space and tooling for manufacture of the train body. Simultaneously, due to the block type structure, the utility model can be freely adjusted and replaced during manufacture, thereby reducing the cost to realize the whole service life of the train body.
Description
Technical field
The utility model relates to a kind of sidewall structure of city railway vehicle, particularly a kind of sidewall structure that is used for the subway car body.
Background technology
At present, the side wall of corrosion-resistant steel or aluminum alloy subway car body mainly adopts one-piece construction, after promptly producing each side wall unit earlier, the whole again side wall module of forming, the side wall module also adopts riveted joint to connect with being connected of top cover and underframe mostly, the interchangeability and the technology difficulty that can cause side wall after the side wall unit composition side wall module, the increase of production time, adopt the riveted joint connection can cause the raising of the leak tightness and the car body maintenance cost of car body simultaneously, also be unfavorable for the control of car load amount of deflection, the amount of deflection of the car body of general riveted joint is got negative value, also greater than the car body of welding manner, this can cause the installation of car door and the reduction of door sealing to its absolute value.
The utility model content
Technical problem to be solved in the utility model is at the prior art deficiency, to provide a kind of and can simplify the side wall module process, saving production time, the sidewall structure that is used for the subway car body of raising body sealing.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of sidewall structure that is used for the subway car body, it comprises a series of closings big side wall and little side wall together, each big side wall and little side wall include column and framed side wallboard respectively, and the upper end of each big side wall and little side wall respectively with the top cover weld together of car body, the lower end of each big side wall and little side wall respectively with the underframe weld together of car body.
Be also to offer window on the framed side wallboard of this big side wall as further improvement of the utility model.
Compared with prior art, the beneficial effect that the utility model had is: the utility model adopts the big side wall of sectional type and the sidewall structure that little side wall closing forms car body together, during the car body assembling, only need be with the assembling of big side wall and little side wall piecemeal, and with the big side wall of each piece and little side wall respectively with the top cover and the underframe integral solder of car body.Like this, the utility model has not only deducted synthetic this road technology of side wall, having saved a large amount of time, place and frock for the car body manufacturing takies, simultaneously owing to adopted the structure of sectional type, in manufacturing process, can arbitrarily adjust, change, reduced the life cycle cost of car body, and utilize the rigidity of side wall module and restraining of providing is provided, the leak tightness that helps controlling the amount of deflection of car load and improve car load, more can effectively reduce maintenance cost, simplify the installation of car door, effectively bring into play the sealing function of car door.
Description of drawings
Fig. 1: the utility model one embodiment side wall module is formed scheme drawing, and it is made up of big side wall 1 and little side wall 2, does not have annexation between each side wall.
Fig. 2: the utility model one embodiment side wall module and the top cover of car body and the interface relationship between underframe, the left side is represented is interface relationship between column and top cover and underframe, the right indicates is interface relationship between framed side wallboard 12 and car body top cover and underframe.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model one embodiment comprises a series of closings big side wall 1 and little side wall 2 together.Each big side wall 1 and little side wall 2 include column 11 and framed side wallboard 12 respectively, and this column 11 plays main load effect, and framed side wallboard 12 works to connect column 11 between two root posts 11.Also offer window 13 on the framed side wallboard 12 of this big side wall 1.The upper end of each big side wall 1 and little side wall 2 respectively with top cover 3 weld togethers of car body, underframe 4 weld togethers of its lower end and car body.
Claims (2)
1. sidewall structure that is used for the subway car body, it is characterized in that comprising a series of closings big side wall and little side wall together, each big side wall and little side wall include column and framed side wallboard respectively, and the upper end of each big side wall and little side wall respectively with the top cover weld together of car body, the lower end of each big side wall and little side wall respectively with the underframe weld together of car body.
2. the sidewall structure that is used for the subway car body according to claim 1 is characterized in that, also offers window on the framed side wallboard of this big side wall.
