The transmission assembly 103 includes a first shaft 103a inserted into the inner cavity of the housing 101, a first flange 103b fixedly connected to one side of the first shaft 103a, and a first bevel gear 103c welded to the other side of the first shaft 103a; the transmission assembly 103 also includes a bevel gear set 103d meshing with the side wall of the first bevel gear 103c, and a second bevel gear 103e meshing with the side wall of the bevel gear set 103d; the transmission assembly 103 also includes a second shaft 103f welded to the side wall of the second bevel gear 103e, and a second flange 103g fixedly connected to the end of the second shaft 103f.

[0019] Specifically, the top of the outer casing 101 is connected to the connecting casing 102, the internal transmission assembly 103 is inserted, and it is connected to the outside through the connecting assembly 104. The overall layout is compact. The first shaft 103a drives the first bevel gear 103c, and the power is transmitted to the second bevel gear 103e through the bevel gear set 103d, and then output by the second shaft 103f, realizing smooth power transmission. The first flange 103b and the second flange 103g provide a stable connection base.

[0020] Furthermore, the top of the outer shell 101 is rotatably connected to a fixed column 105, a main reinforcing rib 106 welded to the side wall of the connecting shell 102, an auxiliary reinforcing rib 107 fixedly connected to the surface of the connecting shell 102, and a third flange 108 welded to the top of the connecting shell 102; the first shaft 103a and the second shaft 103f are connected to the inner wall of the connecting shell 102 through bearings, and the side wall of the bevel gear set 103d is connected to the inner cavity of the connecting shell 102 through bolts.

[0021] Preferably, the connecting shell 102 has a main reinforcing rib 106 welded to its side wall, an auxiliary reinforcing rib 107 fixed to its surface, and a third flange 108 welded to its top, which together form a stable support structure and enhance the load-bearing capacity of key parts. The first shaft 103a and the second shaft 103f are connected to the inner wall of the connecting shell 102 through bearings to ensure smooth rotation and reliable support. The bevel gear set 103d is fixed to the inner cavity of the connecting shell 102 by bolts, which is a firm connection and ensures stable power transmission.

[0022] It should be noted that the connecting assembly 104 includes a tire connecting plate 104a bolted to the side wall of the first flange 103b, and a dustproof pad 104b fixedly connected to the surface of the first flange 103b; the connecting assembly 104 also includes a waterproof pad 104c fixedly connected to the side wall of the first flange 103b, and a connecting hole 104d opened in the side wall of the tire connecting plate 104a.

The dustproof pad 104b is tightly attached to the surface of the first flange 103b to effectively prevent dust from entering and protect the internal transmission components. The waterproof pad 104c further prevents water penetration and enhances the protection of key connection parts.

[0024] In use, power is input from the first shaft 103a and drives the first flange 103b at one end and the first bevel gear 103c welded to the other side to rotate synchronously. The first bevel gear 103c drives the bevel gear set 103d that meshes with it to rotate, which in turn drives the second bevel gear 103e that meshes with it to rotate. Finally, the power is output by the second shaft 103f welded to the side wall of the second bevel gear 103e, realizing the change of power direction and smooth transmission. The first flange 103b and the second flange 103g provide a solid foundation for the connection. The main reinforcing rib 106 on the side wall of the connecting shell 102 and the auxiliary reinforcing rib 107 on the surface together enhance the load-bearing capacity of key parts. The top third flange 108 provides an external connection interface. The first shaft 103a and the second shaft 103f are connected to the inner wall of the connecting shell 102 through bearings to ensure smooth rotation. The bevel gear set 103d is firmly fixed by bolts to ensure stable power transmission. The tire connecting disc 104a is connected to the first flange 103b by bolts, and together with the dustproof pad 104b and the waterproof pad 104c, a reliable connection and effective protection are achieved.

[0025] In summary, the outer shell 101 and the connecting shell 102 are fixedly connected in a separate manner. The internally inserted transmission component 103 facilitates assembly and maintenance. The first shaft 103a is driven by the meshing of the first bevel gear 103c and the bevel gear set 103d, and then transmitted to the second shaft 103f through the second bevel gear 103e, which improves the torque transmission efficiency. The tire connecting disc 104a is firmly connected to the first flange 103b by bolts and is equipped with a dustproof pad 104b and a waterproof pad 104c. This not only achieves a firm connection between the tire and the axle, but also effectively prevents the intrusion of dust and moisture.
