At this time, the roll-over shaft sleeve 4 can be jointly supported by the left connecting pipe 2, the right connecting pipe 3, the left reinforcing frame 5 and the right reinforcing frame 6, and the overall structural strength is further improved.
Specifically, as shown in fig. 1, the left reinforcing frame 5 and the right reinforcing frame 6 are both provided in a box-shaped structure, and are respectively covered on the end portions of the left connecting pipe 2 and the right connecting pipe 3, so that the overall structure is simple and beautiful.
Optionally, the rear beam assembly further comprises a rear towing hook 7, and the rear towing hook 7 is fixedly connected with the rear beam 1 to be used for buckling and hanging objects, so that the rear beam assembly is more versatile in function and higher in integration level. Since the structure of the rear tow hook 7 is prior art, it will not be described in detail herein.
In other aspects, as for the specific connection mode, the adjacent parts of the rear cross beam assembly are mainly fixed through welding. Exemplarily, the following weld arrangements can be made with reference to fig. 2: the rear cross beam 1 is fixedly welded with the right connecting pipe 3 through a first welding seam 10; the turnover shaft sleeve 4 is fixedly welded with the right connecting pipe 3 through a second welding seam 20; the left reinforcing frame 5 is fixedly welded with the trip shaft sleeve 4 through a third welding line 30; the left reinforcing frame 5 is fixedly welded with the left connecting pipe 2 through a fourth welding seam 40; the rear towing hook 7 is fixedly connected to the rear cross member 1 by a fifth welding seam 50. As for the welding seam between the rear cross beam 1 and the left connecting pipe 2, the welding seam between the turnover shaft sleeve pipe 4 and the left connecting pipe 2, the welding seam between the right reinforcing frame 6 and the turnover shaft sleeve pipe 4, and the welding seam between the right reinforcing frame 6 and the right connecting pipe 3, the above settings can be referred to, and the welding seams are integrally arranged in a bilateral symmetry manner.
In conclusion, the embodiment provides a rear cross beam assembly, which improves the bending rigidity and the torsional rigidity of the rear part of the frame assembly and can meet the requirements on the strength and the rigidity of the frame assembly of the dump truck without the auxiliary frame assembly. Simultaneously, this rear beam assembly has integrateed trip shaft sleeve pipe 4 and back tow hook 7, and the function is more various.
