Description

Technical Field

[0001] This utility model relates to a wheel hub, or more precisely, a multifunctional motorcycle wheel hub. Background Technology

[0002] Currently, small-displacement scooter motorcycles generally use drum brakes on the rear wheel. However, with the improvement of overall vehicle configurations, some consumers also demand disc brakes on the rear wheel. During model development, manufacturers design two rear wheel systems to accommodate different braking methods, which increases development costs and mold expenses. Utility Model Content

[0003] Therefore, it is necessary to provide a multifunctional motorcycle wheel hub to address the aforementioned technical problems.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A multi-functional motorcycle wheel hub, characterized in that the multi-functional motorcycle wheel hub includes an annular outer rim, an annular inner rim is provided at the center of the outer rim, a plurality of spokes are provided between the inner rim and the outer rim, a mounting base is provided at the bottom of the inner rim, the mounting base and the inner rim form a drum brake mounting cavity, a mounting center shaft is provided at the center of the inner side of the mounting base, a through spline hole is provided at the center of the mounting center shaft, a plurality of circumferentially distributed disc brake mounting screws are provided on the outer side of the mounting base, and a detachable disc brake disc is provided on the outer side of the disc brake mounting screws.

[0006] In a preferred embodiment of this utility model, the disc brake disc is provided with a plurality of disc holes, and the disc holes are connected to the disc brake mounting screw tube by mounting bolts.

[0007] In a preferred embodiment of this utility model, the outer rim, inner rim, and spokes are integrally formed from aluminum alloy.

[0008] In a preferred embodiment of this utility model, the number of disc brake mounting screws is five.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] This utility model provides a multifunctional motorcycle wheel hub that utilizes the drum brake mounting cavity to install the brake drum of a drum brake. When a disc brake needs to be installed, the disc brake disc can be directly installed using the disc brake mounting screw, greatly facilitating users to upgrade or switch braking methods. The effect is obvious and the practicality is strong. Attached Figure Description

[0011] To more clearly illustrate the solutions in this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below.

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] like Figures 1 to 4 As shown, the multi-functional motorcycle wheel hub includes an annular outer rim 1, an annular inner rim 5 at the center of the outer rim 1, several spokes 7 between the inner rim 5 and the outer rim 1, a mounting base 8 at the bottom of the inner rim 5, the mounting base 8 and the inner rim 5 forming a drum brake mounting cavity S, a mounting center shaft 6 at the center of the inner side of the mounting base 8, a through spline hole 61 at the center of the mounting center shaft 6, several circumferentially distributed disc brake mounting screws 2 on the outer side of the mounting base 8, and a detachable disc brake disc 3 on the outer side of the disc brake mounting screws 2.

[0019] The disc brake disc 3 has several disc holes 31, which are connected to the disc brake mounting screw tube 2 by mounting bolts 4.

[0020] It should be noted that the outer rim 1, inner rim 5, and spokes 7 are all integrally formed from aluminum alloy. The disc brake mounting screws 2 number five.

[0021] The working principle of this multi-functional motorcycle wheel hub is explained below.

[0022] The drum brake mounting cavity S can be used to install the brake drum of a drum brake. When a disc brake needs to be installed, the disc brake disc 3 can be directly installed using the disc brake mounting screw 2, which greatly facilitates users in upgrading or switching the braking method, with obvious effects and strong practicality.

[0023] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application.
