[0019] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] Referring to Figures 1-4 The utility model provides a technical scheme:

[0021] A commercial vehicle balance shaft support structure, including support main body 1, support main body 1 outer wall is fixedly connected with connecting end one 2 and connecting end two 3, is set up with multiple groups of screw holes 5 on connecting end two 3, and connecting end two 3 outside is integrated with the enhancement assembly for connecting multiple groups of screw holes 5, and the reinforcing rib 4 is fixedly connected between connecting end one 2 and support main body 1, and the enhancement assembly includes the boss 6 fixedly connected with connecting end two 3, and multiple groups of screw holes 5 are connected through the boss 6;

[0022] By increasing the curvature of the curved section 401, the length ratio of the vertical section 402 is reduced, and the smooth arc transition enables the stress to be more evenly distributed in the entire structure, thereby reducing local stress peaks and improving the overall load-carrying capacity. At the same time, by connecting multiple screw holes 5 through the boss 6, the load acting on each screw hole 5 can be dispersed to some extent, making the stress more evenly distributed on the entire boss 6 structure rather than concentrated around a single screw hole 5. The product structure is more reasonable, effectively improving the pressure-bearing capacity of the commercial vehicle balance shaft support structure.

[0023] Specifically, as Figure 2 As shown in Figure 4 The reinforcing rib 4 is composed of a curved section 401 and a vertical section 402. By increasing the curvature of the curved section 401, the length ratio of the vertical section 402 is reduced, and the smooth arc transition enables the stress to be more evenly distributed in the entire structure, thereby reducing local stress peaks. The support main body 1, connecting end two 3 and reinforcing rib 4 are integrally formed, and the boss 6 and connecting end two 3 are integrally formed, ensuring the strength of the connection between the support main body 1, connecting end two 3 and reinforcing rib 4, and the boss 6 and connecting end two 3.

[0024] Working principle: By increasing the curvature of the curved section 401, the length ratio of the vertical section 402 is reduced, and the smooth arc transition enables the stress to be more evenly distributed in the entire structure, thereby reducing local stress peaks and improving the overall load-carrying capacity. At the same time, by connecting multiple screw holes 5 through the boss 6, the load acting on each screw hole 5 can be dispersed to some extent, making the stress more evenly distributed on the entire boss 6 structure rather than concentrated around a single screw hole 5. The product structure is more reasonable, effectively improving the pressure-bearing capacity of the commercial vehicle balance shaft support structure.
