摘要： A vehicle body structure includes a perimeter frame including laterally spaced right and left side rails of tubular construction and front and rear bumper rails of tubular construction extending between the side rails. A structural tunnel extends longitudinally of the vehicle midway between the side rails and has front and rear ends. The structural tunnel includes an inverted U-shaped channel having vertically depending the first and second legs, and a close-out plate which extends horizontally between the legs. First and second front shear walls extend forwardly and diagonally from the first and second legs at the front of the tunnel to the respective right and left side rails of the perimeter frame. Similarly, first and second rear shear walls extend generally rearward and diagonally from the first and second legs at the rear end of the tunnel to the respective left and right side rails of the perimeter frame. Reinforcement plates are welded along side the front shear walls and the rear shear walls to additionally connect the legs of the structural tunnel with the right and left side rails. Right and left rear pillars are attached respectively to the right and left side rails of the perimeter frames, and right and left seat back shear walls extend laterally between the rear ends of the tunnel and the right and left pillars. The body structure is additionally stiffened by reinforcing brackets which extend between the front and rear shear walls and the perimeter frames.
摘要翻译：车身结构包括周边框架，其包括横向间隔开的管状结构的左右侧轨道和在侧轨之间延伸的管状结构的前后保险杠轨道。一个结构隧道在两个侧轨之间的中间部分延伸，并具有前端和后端。结构通道包括具有垂直于第一和第二腿部的垂直的U形通道，以及在腿部之间水平延伸的闭合板。第一和第二前剪力墙从隧道前部的第一和第二腿向前并对角地延伸到周边框架的相应的右侧和左侧轨道。类似地，第一和第二后剪力墙从隧道后端处的第一和第二腿大致向后并对角地延伸到周边框架的相应的左侧和右侧轨道。加固板在前剪力墙和后剪力墙的一侧被焊接，以将结构通道的腿与左右侧轨道另外连接。右后柱和左后支柱分别安装在周边框架的左右侧轨道上，右侧和左侧后座剪力墙在隧道后端和左右支柱之间横向延伸。身体结构通过在前后剪力墙和周边框架之间延伸的加强支架进一步加固。
