Description

Technical Field

[0001] This utility model relates to the field of wheel hub disassembly and assembly technology, and in particular to a modular, quick-replacement locomotive wheel hub assembly. Background Technology

[0002] The wheel rim is the component around which the tire is mounted. Together with the tire, it forms the wheel, supporting the tire, fixing its position, and bearing the weight of the vehicle and various forces during driving. The material and structural design of the rim affect the strength, weight, and performance of the wheel. The most vulnerable parts of the wheel hub are mainly concentrated in the rim itself, the bolt holes, the bearing mounting points, and the surface coating. As the outermost part of the wheel hub in contact with the tire, the rim is prone to deformation, cracking, and even tire blowouts when encountering potholes, speed bumps, or curbs while driving.

[0003] However, in current technology, wheel hubs mostly adopt a one-piece structure. While this design ensures overall strength, it has obvious drawbacks. When local parts such as the rim or bolt holes are damaged due to impact or wear, structural limitations prevent individual replacement of the damaged parts. Instead, the entire wheel hub assembly must be replaced, leading to a significant increase in maintenance costs and a waste of material resources. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a modular, quick-change locomotive wheel hub assembly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a modular, quick-change locomotive wheel hub assembly, comprising an inner hub module and an outer hub module. One side of the inner hub module is bent inward to form a bending ring I. The surface of the bending ring I is provided with a plurality of positioning holes I at equal intervals. One side of the outer hub module is bent inward to form a bending ring II. The surface of the bending ring II is provided with a plurality of positioning holes II at equal intervals. A spoke module is provided between the inner hub module and the outer hub module. The spoke module includes a spoke body and a positioning ring. The outer diameter of the spoke body is equal to the outer diameter of the bending ring I. The surface of the spoke body is provided with positioning holes III at equal intervals corresponding to the positions of the positioning holes I. A retaining ring is installed on the inner sidewall of the outer hub module. The inner diameter of the retaining ring is smaller than the inner diameter of the bending ring II. The inner sidewall of the positioning holes II is provided with internal threads. The spoke module is installed between the inner hub module and the outer hub module by screws.

[0006] Preferably, the spoke body and the positioning ring are located on the same axis, and the surface of the positioning ring is provided with four positioning holes at equal intervals.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1-4 As shown, this utility model provides a modular, quick-change locomotive wheel hub assembly, including an inner hub module 1 and an outer hub module 2. One side of the inner hub module 1 is bent inward to form a bending ring 11, and the surface of the bending ring 11 is provided with a plurality of positioning holes 12 at equal intervals. One side of the outer hub module 2 is bent inward to form a bending ring 22, and the surface of the bending ring 22 is provided with a plurality of positioning holes 23 at equal intervals. A spoke is provided between the inner hub module 1 and the outer hub module 2. Module 3, the spoke module 3 includes a spoke body 31 and a positioning ring 33. The outer diameter of the spoke body 31 is equal to the outer diameter of the bending ring 11. Positioning holes 32 are equally spaced on the surface of the spoke body 31 corresponding to the positions of positioning holes 12. A retaining ring 21 is installed on the inner side wall of the outer hub module 2. The inner diameter of the retaining ring 21 is smaller than the inner diameter of the bending ring 22. The inner side wall of the positioning hole 23 is provided with internal threads. The spoke module 3 is installed between the inner hub module 1 and the outer hub module 2 by screws.

[0022] The specific setup and function of this embodiment are described below. The wheel hub consists of two main parts: an inner wheel hub module 1 and an outer wheel hub module 2. The width of the outer wheel hub module 2 is smaller than the width of the inner wheel hub module 1. The spoke module 3 is assembled between the inner wheel hub module 1 and the outer wheel hub module 2. A bending ring 11 and a bending ring 22 are respectively provided on adjacent sides of the inner wheel hub module 1 and the outer wheel hub module 2. The surfaces of the bending ring 11 and the bending ring 22 are parallel. During assembly, the bending ring 11 and the bending ring 22 form a gap of equal thickness. The gap is used to install the outer periphery of the spoke body 31. The inner wheel hub module 1, the outer wheel hub module 2, and the spoke module 3 are installed by screws with external hexagonal heads, with the external hexagonal heads facing the inner wheel hub module 1. Inside the hub module 1, a retaining ring 21 is set in the outer hub module 2. The retaining ring 21 is used to cover the part of the screw end exposed from the positioning hole 23, so that the fastener is installed in a concealed manner. After the whole assembly is completed, the inner hub module 1 is oriented towards the axle of the locomotive, and the axle is connected to the axle disc module 4. At this time, the parts cannot be directly disassembled from the outside. This not only improves the aesthetics of the detachable parts of the hub, but also avoids damage caused by human disassembly of fastener parts, ensuring the safety of the hub during use. If parts need to be replaced, the entire hub must be removed from the axle first, and then the screws can be unscrewed from the inside. After the inner hub module 1, outer hub module 2 and spoke module 3 are disassembled, the parts that need to be replaced can be replaced.

[0023] Example 2: Figure 2 and Figure 3 As shown, the spoke body 31 and the positioning ring 33 are located on the same axis. Positioning holes 44 are evenly spaced on the surface of the positioning ring 33. An axle disc module 4 is installed at the center of the positioning ring 33. Axle disc holes 41 are provided on the surface of the axle disc module 4 at positions corresponding to the positioning holes 44. The spoke body 31 is a concentric circle structure composed of two rings connected by spokes. The outer diameter of the positioning ring 33 is smaller than the outer diameter of the inner ring of the spoke body 31. The positioning ring 33 is installed on the inner side of the spoke body 31, and the axle disc module 4 is installed on the side of the positioning ring 33 by screws. One side of the axle disc module 4 has a circular boss that matches the size of the center hole of the positioning ring 33, and the other side of the axle disc module 4 has an installation port adapted to the axle, with a groove at the center of the circular boss.

[0024] The overall effect of this embodiment is that the spoke module 3 is designed as an outwardly convex arch, with the inner ring of the spoke body 31 facing outwards and the inner ring of the spoke body 31 facing inwards. The arched deformation generated by the intermediate connecting spokes provides support for the surfaces of the inner hub module 1 and the outer hub module 2, ensuring the roundness of the inner hub module 1 and the outer hub module 2 and preventing deformation under pressure. At the same time, a positioning ring 33 is set on the inner side of the spoke body 31. The positioning ring 33 is used to install the axle plate module 4. The screw is installed by engaging the axle plate hole 41 and the positioning hole 34. The inner ring of the spoke body 31 covers the exposed end of the screw, thus achieving the concealed installation of the inner hub module 1, the spoke module 3 and the axle plate module 4. Similarly, the spoke module 3 and the axle plate module 4 can be replaced in time when damaged. A round boss and a groove are set on the outer surface of the axle plate module 4. The manufacturer's logo can be installed in the groove for corporate promotion.

[0025] The usage and working principle of this device are as follows: The inner hub module 1 and the outer hub module 2 are separated by a gap formed by the parallel arrangement of bending ring 11 and bending ring 22. The outer periphery of the spoke body 31 of the spoke module 3 is inserted into this gap and fixed by screws passing through positioning holes 12, 32 and 23. The outer hexagonal head faces the inside of the inner hub module 1. The retaining ring 21 of the outer hub module 2 covers the screw ends, forming a concealed installation to prevent human disassembly. The spoke body 31 is a two-ring concentric circle structure connected by spokes to form an arch shape. The deformation supports the inner hub module 1 and the outer hub module 2 to maintain roundness. The positioning ring 33 is installed inside the spoke body 31. The axle plate module 4 is fixed by screws that cooperate with the positioning hole 44 and the axle plate hole 41. Its round boss and groove design can be used to install a logo. The inner ring of the spoke body 31 covers the screw ends. When a module is damaged, the hub needs to be removed from the axle and the screws need to be removed from the inside to replace the corresponding module, realizing modular quick replacement and structural protection.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
