In order to increase the internal space of the cab, the bending radius is designed to enable the bending cross beam to be close to the theoretical position of the hood as much as possible and keep a distance of not less than 30mm with the hood. Meanwhile, the bending radius is selected by considering the stretch bending manufacturability of the aluminum profile, and the defects of cracks, orange peel and the like are not allowed to be generated.
The connection beam 5 includes a first connection beam for connecting the window upper cross member 3 and the window lower cross member 4, and a second connection beam for connecting the window lower cross member 4 and the vehicle body under frame. The connecting and supporting functions are mainly achieved, and the structural stability of the cab framework is guaranteed. The cross section of the connecting beam 5 is the same as that of the rear ring beam. The welding position of the end beam and the underframe of the vehicle body is an end beam or a structural support with certain strength, so that the load borne by the cab is safely transferred to the underframe.
