    • In a vehicle frame structure, an upper edge of a frame member is fixed to a lower face of a substantially flat panel, and a bottom wall of an upper stiffener fixed to an inner face of an upper part of a curved portion of the frame member and a bottom wall of a lower stiffener fixed to an outer face of a lower part of a region between two inflection points of the curved portion are arranged in an X shape relative to a top point of the curved portion. Therefore, when a compressive load in the longitudinal direction acts on the frame member, the curved portion of the frame member is effectively prevented from bending by counterbalancing the upward load acting on the lower stiffener bottom wall with the downward load acting on the upper stiffener bottom wall. Moreover, the upper stiffener and the lower stiffener are U-shaped cross-section members that can be formed by bent sheet metal, and thereby minimize any increase in weight due to installation of the stiffeners.
    • 在车架结构中,框架构件的上边缘固定到基本平坦的板的下表面,并且固定在框架构件的弯曲部分的上部的内表面的上加强件的底壁 并且固定到弯曲部分的两个拐点之间的区域的下部的外表面的下加强筋的底壁相对于弯曲部分的顶点布置成X形。 因此,当纵向方向上的压缩载荷作用在框架构件上时,通过平衡作用在下加强件底壁上的向上的载荷,有效地防止了框架构件的弯曲部分的弯曲,而向下的载荷作用在上加强筋底部 壁。 此外,上加强件和下加强件是可由弯曲的金属板形成的U形横截面构件,从而由于加强件的安装而使重量的任何增加最小化。
