The invention discloses a novel cross beam cavity structure for improving the bending and torsional rigidity of a light truck, and relates to the technical field of truck bodies. In order to provide a mounting point for a front wheel fender for an existing commercial vehicle cab, the traditional design thought is that a Z-shaped connecting structure is designed between the rear section of a front longitudinal beam and a rear apron board, one end of the Z-shaped flange is welded with the floor panel, and the other end of the Z-shaped flange provides a mounting surface for the mud guard, so the bending and torsional rigidity of the Z-shaped structure is low. A front longitudinal beam rear section is installed at the upper end of the rear suspension cross beam, a rear suspension support assembly is arranged on one side of the front longitudinal beam rear section, a front floor rear section is installed at the lower end of the rear suspension cross beam, a front longitudinal beam front section is arranged on one side of the front floor rear section, and a rear apron board is installed at the tail of the rear suspension cross beam; a doorsill beam is arranged at the lower end of the rear apron board, and a rear suspension cross beam cavity is formed among the rear suspension cross beam, the front longitudinal beam rear section, the front floor rear section and the rear apron board.

    本发明公开了一种提升轻卡弯扭刚度的新型横梁空腔结构,涉及车身技术领域,为解决现有的商用车驾驶室为了给前轮挡泥皮提供安装点,传统的设计思路是:前纵梁后段与后裙板之间设计一个Z字形的连接结构,Z字形翻边一端与地板面板打焊点,另一端为挡泥皮提供安装面,这种Z字形结构弯扭刚度较低的问题。所述后悬置横梁的上端安装有前纵梁后段,所述前纵梁后段的一侧设置有后悬置支架总成,所述后悬置横梁的下端安装有前地板后段,所述前地板后段的一侧设置有前纵梁前段,所述后悬置横梁的尾部安装有后裙板,所述后裙板的下端设置有门槛梁,所述后悬置横梁、前纵梁后段、前地板后段、后裙板之间设置有后悬置横梁空腔。
