Description

Light motorcycle wheel hub

Technical Field

The utility model belongs to the technical field of general vehicle, a light motorcycle wheel hub is specifically disclosed.

Background

The rim, commonly known as a rim, is a component that mounts and supports the tire on the wheel at its upper periphery, and forms the wheel with the spokes.

The traditional industrial rim is made of steel and alloy materials, the raw materials are expensive, the manufacturing cost is high, meanwhile, the energy consumption is high due to the large weight, and the cruising ability of the locomotive is reduced. The rim made of the aluminum material solves the weight problem, but has high cost, and is easy to deform and have traffic accidents due to insufficient hardness of the aluminum material, so that the service life of the wheel is influenced.

Based on this, it is necessary to provide a new rim structure, which solves the problems of weight, cost and service life of the wheel.

Disclosure of Invention

In order to solve the problems, the utility model provides a light motorcycle wheel hub, which comprises a rim outer ring, wherein a ceramic inner ring is arranged on the inner side of the rim outer ring, a plurality of lock columns are arranged on the inner surface of the ceramic inner ring along the circumferential direction, the lock columns are triangular prisms, and the single lock column is axially arranged; the side surface of the ceramic inner ring is provided with a mounting hole which axially penetrates through the ceramic inner ring.

The beneficial effect of this scheme lies in:

1. the triangular prism of the rim reduces the traction force required by the driving of the motorcycle, saves energy, reduces consumption, reduces the driving cost of the locomotive and improves the cruising ability of the locomotive;

2. the rim has high strength and long service life, saves manufacturing materials and saves manufacturing cost;

3. the moment formed by the triangular prism structure of the lock cylinder is larger than that of the cylinder, so that the rotating shaft is more labor-saving in the rotating process;

4. the mounting holes are used in groups, and the connection between the rim and the spoke and between the rim and the tire is more stable.

Furthermore, the lock cylinders are uniformly distributed along the circumferential direction of the ceramic inner ring.

The fore shaft cooperation of lock post and spoke is connected, and when the spoke rotated and drives the rim and rotate, evenly distributed's connection structure made the spoke more balanced to the effort of rim, made the wheel operation more steady.

Further, the lock cylinder and the ceramic inner ring are integrally formed. The lock cylinder and the ceramic inner ring are integrally formed, so that the step of manufacturing the ceramic inner ring is simplified.

Furthermore, the mounting holes are uniformly distributed along the circumferential direction of the bottom surface of the ceramic inner ring. The distribution of the mounting holes is matched with the spoke structure.

Further, the number of the mounting holes is 8-24. The mounting holes are used in groups, and after one group of mounting holes are worn, the spoke is only required to be turned to be replaced by the next group of mounting holes for continuous use, so that the rim maintenance cost is saved.

Further, the inner wall of the mounting hole is provided with threads. The threads are matched with the screws, so that the friction force generated by the inner wall of the mounting hole to the mounting piece is increased, and the connection between the spoke and the rim is enhanced.

Furthermore, the surfaces of the rim, the ceramic inner ring and the mounting ring are coated with anaerobic adhesive layers.

Prevent rim, ceramic inner circle, collar from being oxidized.

Further, the outer layer of the anaerobic adhesive layer is coated with an aluminum alloy protective layer.

The rim, the ceramic inner ring and the mounting ring are protected from being abraded, and the service life of the wheel is prolonged.

fig. 2 is a side view of an embodiment of the present invention.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the wheel rim comprises a rim outer ring 1, a ceramic inner ring 2 and a lock cylinder 3.

Example 1

Example 1 is substantially as shown in figures 1 and 2: the light motorcycle hub provided by the embodiment is applied to a Yadi electric motorcycle with the model number of Guanzhi E32.0. The rim comprises a rim outer ring 1, the rim outer ring 1 is made of composite steel, the inner side of the rim outer ring 1 is provided with a ceramic inner ring 2, the ceramic inner ring 2 is used for replacing the traditional composite steel, the process for manufacturing the ceramic inner ring 2 is simpler than the process for using the composite steel, the ceramic is cheap compared with the composite steel, the production cost is greatly reduced, and the resource waste is also avoided; meanwhile, because the ceramic is light and convenient compared with composite steel, the load of the electric motorcycle is reduced, the battery endurance is improved, the trouble and the battery loss caused by frequent charging are avoided, and the service life of parts is prolonged.

Regular triangular prism-shaped lock cylinders 3 are uniformly machined on the inner side surface of the ceramic inner ring 2 in the circumferential direction, and the lock cylinders 3 and the ceramic inner ring 2 are integrally formed. The single lock cylinder 3 is axially arranged, the angular bisector of the vertex angle of the regular triangular prism coincides with the diameter of the ceramic inner ring 2, the structure can provide the maximum torque for the rim drive, and raw materials are saved during manufacturing.

The Yadi crown intelligent E32.0 electric motorcycle wheel is provided with 4 spokes, 8 mounting holes are formed in the surface of the ceramic inner ring 2, the mounting holes are uniformly distributed and vertically penetrate through the ceramic inner ring 2, threads are machined on the inner side of each mounting hole and matched with screws, friction force generated by the inner wall of each mounting hole to a mounting piece is reduced, and the installation is simpler and more convenient. Adopt A group mounting hole during first installation, because long-term use takes place wearing and tearing when the mounting hole, need not to abandon the rim, directly replace A group mounting hole into B group mounting hole and continue to use, reduce the electric motor car maintenance cost.

Practical application data shows, uses the utility model discloses the yadi hat intelligence E32.0 electric motorcycle of rim structure, it charges once later, and duration reaches 1.5 times of traditional electric motorcycle before the improvement.
