[0002] As a key component of the vehicle transmission system, the locking structure of the axle wheel rim can be traced back to early mechanical fixing methods, such as bolt locking and pin positioning. With the advancement of industrial technology, it has gradually developed into more efficient hydraulic locking, self-locking nuts, and conical sleeves to improve load-bearing capacity and reliability. Throughout its development, advancements in materials science and improvements in manufacturing processes have further optimized the performance and durability of the locking structure. Modern applications cover commercial vehicles, construction machinery, agricultural equipment, and special vehicles. Especially under heavy loads, high speeds, or harsh conditions, the locking structure needs to balance anti-loosening, impact resistance, and ease of maintenance. Meanwhile, with the trends of electrification and intelligentization, the integration of sensors and adaptive locking technology has also become a new research direction.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example

[0026] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a locking structure for the wheel rim of an axle, comprising:

[0027] Axle half shaft 101, brake hub 102 bolted to the side wall of axle half shaft 101, brake base plate 104 fixedly connected to the bottom of brake hub 102, and locking assembly 103 fixedly connected to the surface of brake hub 102.

[0028] Specifically, the locking assembly 103 includes a locking plate 103a bolted to the surface of the brake drum 102, a bolt 103b threaded to the surface of the locking plate 103a, and a nut 103c engaged with the side wall of the locking plate 103a.

[0029] The locking plate 103a has a notch on its side wall and the nut 103c has a protrusion on its side wall. The nut 103c is fixed by rotating the nut 103c with a tool, and the bolt 103b is used to fix the nut 103c by the protrusion on its side wall through the notch on the side wall of the locking plate 103a, thereby locking the wheel edge of the axle.

[0030] Furthermore, the bridge half-shaft 101 is threadedly connected to an asbestos pad 105 on its side wall, and a half-shaft locking plate 106 is threadedly connected to the side wall of the asbestos pad 105. The half-shaft locking plate 106 is threadedly connected to a half-shaft fastening plate 107 on its side wall, and the inner wall of the half-shaft fastening plate 107 is threaded.

[0031] The thread on the inner wall of the half-shaft fastening plate 107 is connected to the side wall of the bridge half-shaft 101 by bolts 103b, so that the half-shaft fastening plate 107 can be tightly fixed on the bridge half-shaft 101. The connection between the half-shaft locking plate 106 and the asbestos pad 105 on the side wall of the bridge half-shaft 101 further enhances the stability and reliability of the locking structure.

[0032] Preferably, a bearing housing 108 is fixedly connected to the outer wall of the axle half shaft 101, a brake base plate 104 is fixedly connected to the surface of the bearing housing 108, a gasket 109 is threadedly connected to the side wall of the bearing housing 108, and a mounting plate 110 is threadedly connected to the side wall of the bearing housing 108.

[0033] The mounting plate 110 has mounting holes on its surface. The gasket 109 can effectively increase the sealing between the bearing housing 108 and the mounting plate 110. At the same time, the bearing housing 108 provides a stable support for the brake base plate 104, so that the brake can be stably fixed on the axle.

[0034] It should be noted that a shaft head 111 is fixedly connected to the side wall of the mounting plate 110. The shaft head 111 is fixedly connected to the surface of the bridge half shaft 101. A bridge housing 112 is fixedly connected to the surface of the bridge half shaft 101. There are two bridge housings 112.

[0035] The axle housing 112 and the axle half shaft 101 are precisely fitted together to ensure the rigidity and stability of the axle.

[0036] When the axle wheel rim needs to be locked, first use a tool to rotate the nut 103c to fix the wheel rim. Simultaneously, use bolts 103b to fix the nut 103c to the convex sidewall of the nut 103c via the recess on the sidewall of the locking plate 103a, thus locking the axle wheel rim. At the same time, bolts 103b connect the half-shaft fastening plate 107 to the sidewall of the axle half-shaft 101. The cooperation between the half-shaft locking plate 106 and the asbestos gasket 105 enhances the locking effect. The bearing seat 108 fixed to the outer wall of the axle half-shaft 101 is for braking. The brake base plate 104 provides stable support, and the brake base plate 104 is connected to the vehicle body or other related components by fasteners such as bolts 103b, ensuring that the brake can be firmly fixed to the axle. The mounting plate 110 is threaded to the side wall of the bearing seat 108 by a gasket 109, which not only increases the sealing performance, but also provides additional stability and reliability for the entire locking structure. The axle head 111, as a key component connecting the axle half shaft 101 and the mounting plate 110, ensures the effective transmission of force.

[0037] In summary, the effective locking of the axle wheel edge is achieved through the cooperation between the axle half-shaft 101 and the brake drum 102; the locking effect and stability of the axle wheel edge are achieved through the cooperation between the locking assembly 103 and the brake drum 102; the secure connection between the locking assembly 103 and the axle half-shaft 101 is achieved through the cooperation between the half-shaft locking plate 106 and the half-shaft fastening plate 107; the overall stability and safety of the axle wheel edge locking structure are achieved through the cooperation between the bearing seat 108 and the mounting plate 110; and the rigidity and stability of the axle are achieved through the cooperation between the axle housing 112 and the axle half-shaft 101.
