[0032] Based on the above, in this embodiment, the bearing member 1 is composed of a connection part 11 and connection parts 2 12 on both sides. A gap is left between the connection part 2 12 and the connection part 11, and a support mechanism 2 is arranged in the gap. The reinforcement member 22 connects the connection part 11, and the middle support part 21 is positioned between the connection part 2 12 and connected. Then, the reinforcement member 22 is fixed on the connection part 11 to restrict the middle support part 21, and the connection part 11 cooperates with the connection part 12 to restrict the connection part 2, and the auxiliary connection part 11 is connected to the connection part 2 12. At the same time, the reinforcement member 22 squeezes the connection part 11 to restrict the connection part 2 12, and further strengthens the connection. Finally, the protective component 3 is installed on the connection part 11 through the reinforcement member 22 to strengthen the connection stability of the welding point and improve the overall bearing capacity.

[0033] See also Figure 1-4 The connection part 11 includes a connection plate 111 with a preset through groove, welding holes are symmetrically opened on the connection plate 111, and outer edge protrusions 112 are symmetrically arranged on the connection plate 111. One end of the connection part 2 12 extends to the bottom of the welding hole through the through groove, and one end of the connection part 2 12 is welded to the connection plate 111 through the welding hole, and a connection hole is opened on one end of the connection part 2 12.

[0034] A gap is left between the combination of the above-mentioned connecting part 2 12 and the connecting part 1 1, and the connecting plate 111 can be selected as a channel steel component with a preset through groove. The outer edge protrusion 112 is arranged along the two bent ends of the connecting plate 111, and the connecting part 2 12 adopts a stepped design. A plurality of threaded holes are arranged at the top of the connecting part 12, which is connected to the front overhang part of the truck frame by bolts, and the bottom end is inserted into the connecting plate 111 along the through groove and finally covered on the welding hole. The connecting part 2 12 and the connecting plate 111 are welded through the welding hole, and after the welding of the connecting part 2 12 is completed, a gap is connected on the connecting plate 111.
