摘要:
The present invention relates to a railwaycar body easy to manufacture at a low material cost. The car body comprises a center underframe (2) produced of light-alloy extruded shapes (4) and an end underframe (3) produced of a ferrous material, and furthermore a roof framing, a side framing and an end framing which constitute the car body (40) composed of outer plate members and frame members produced of a ferrous material. According to the present invention, it is possible to build a railwaycar body easy to manufacture at a low material cost by building the car body of a light-alloy material and a ferrous material.
摘要:
The present invention therefore proposes that a shearing rigidity in respect to a vertical load in the portion near the body bolster (A) of a light weight car body (1) is made larger than that of the portion other than a portion near the body bolster (A). That is, a shearing rigidity in respect to the vertical load of a portion near the portion of body bolster (A) of the car body (1) is improved and the portion other than the portion near the body bolster (A) of the car body (1) has a sufficient bending rigidity in the same manner as that of the prior art structure.
