Problems solved by technology

[0011] However, since one vehicle body outer panel and the other vehicle body outer panel are joined by the respective inner panels and outer panels, the connection rigidity between the one vehicle body outer panel and the other vehicle body outer panel is high.
Therefore, in the technology described in Patent Document 1, it takes a lot of labor to remove the deformation between the outer panels of the vehicle body, and there is a problem that the manufacturing man-hours of the vehicle body frame increase.

Embodiment Construction

[0044] Hereinafter, an embodiment of a method for manufacturing a vehicle body frame according to the present invention will be described with reference to the drawings.

[0045] First, before describing a method of manufacturing a vehicle body frame, a schematic structure of a vehicle body according to the present embodiment will be described.

[0046] Such as Figure 10 As shown, the vehicle body frame 1 includes, for example, a roof structure 2 , a plurality of pairs of side structures 4 facing each other, and a floor structure 3 . The top plate structure 2 is joined to the upper edge of each side structure 4 , and the bottom plate structure 3 is joined to the lower edge of each side structure 4 .

[0047] In the present embodiment, the roof structure 2 , the side structures 4 , and the floor structure 3 are all constructed by joining a plurality of metallic vehicle body outer panels to each other. Each of the structures 2 , 3 , 4 is formed so that the longitudinal direct...

Abstract

This method for manufacturing a vehicle frame comprises joining together a roof structure, side structures that face one another, and a floor structure, the method for manufacturing a vehicle frame having: a primary joining step for butt-joining to each other only one set of plates from among the inner face plates and outer face plates in a plurality of panel boards that form the side structures, and producing intermediates of the side structures; a structure joining step for joining together the roof structure, the floor structure, and the intermediates; and a secondary joining step for joining together, after the structure joining step, the other set of plates from among the inner face plates and the outer face plates in the plurality of panel boards that form the intermediates to complete the side structures.

Description

technical field [0001] The present invention relates to a method of manufacturing a vehicle body frame formed by joining a roof structure, side structures facing each other, and a floor structure. [0002] this application claims priority based on Japanese Patent Application No. 2010-225789 for which it applied to Japan on October 5, 2010, and uses the content here. Background technique [0003] A body frame of a rail vehicle is usually produced by joining a roof structure, side structures facing each other, and a floor structure. [0004] Such a method of manufacturing a vehicle body frame is described in, for example, Patent Document 1 below. In the technology described in this patent document 1, structures such as side structures are formed using a plurality of vehicle body outer panels called heavy skins. The vehicle body outer panel has an inner panel and an outer panel facing each other, and a plurality of ribs connecting the inner panel and the outer panel. In the ...
