Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts, and in particular relates to a double-cavity wheel hub. Background Art

[0002] With the development of society and the continuous advancement of science and technology, the functionality, comfort and practicality of automobiles are constantly improving. As an important part of road transportation, automobiles have become an indispensable part of people's travel and transportation. Automobiles have greatly facilitated people's lives, improved people's travel and transportation efficiency, greatly shortened spatial distances, and saved people's time costs.

[0003] In the history of automobile structure development, wheels have always been one of the basic elements of automobile structure. The wheels rotate under the drive of the transmission shaft, and the rolling friction between the wheels and the ground enables the car to move. In the process of gradual evolution of wheel structure, the structure of modern automobile wheels is mainly a combination of wheel hub and tire. The tire is set on the outside of the wheel hub, and the tire and the wheel hub are locked by inflating the tire.

[0004] The wheel hub in the prior art usually has only a pair of wheel rims, and thus can only mount one conventional tire with only one air cavity; furthermore, when the tire of the wheel hub that can only mount one tire explodes, the tire must be repaired or replaced in time to allow the car to continue to work normally, which undoubtedly affects the safety of the car and makes the parts more complicated to use. Utility Model Content

[0005] The purpose of the utility model is to provide a dual-cavity wheel hub, which fixes and supports the rim by fixing a corresponding spoke assembly in a central mounting piece, thereby arranging two sets of independent wheel flanges in the rim to achieve installation of two tires, thereby making the wheel hub have two independent tires and corresponding cavities, reducing the safety risks generated during the driving of the car.

[0006] The purpose of the utility model is achieved by a double-cavity wheel hub, comprising:

[0007] A central mounting piece, wherein the central mounting piece is a cylindrical structure;

[0008] A spoke assembly, the spoke assembly comprising a plurality of spokes, the plurality of spokes being evenly distributed along the circumferential direction of the end of the central mounting member;

[0009] A rim, wherein the rim is a cylindrical structure, and one side of the rim is fixedly arranged with a plurality of the spokes; and

[0010] The rim comprises a rim body fixedly arranged with a plurality of the spokes and a rim group arranged on the outer side of the rim body. The rim group comprises two groups of rims, and each group of the rims is provided with a valve tube.

[0011] Furthermore, the two groups of rims include a first rim and a second rim arranged in sequence in the width direction of the rim body, the first rim including a first outer rim fixedly set away from the spokes and a first inner rim arranged in the middle of the rim body; the second rim includes a second outer rim fixedly set close to the spokes and a second inner rim arranged in the middle of the rim body.

[0012] Furthermore, the first inner wheel rim and the second inner wheel rim are arranged at an interval.

[0013] Furthermore, the central mounting member, the spoke assembly and the rim are an integral structure.

[0014] Furthermore, the first valve tube of the first wheel rim is fixedly arranged in the first outer wheel rim, the air inlet end of the first valve tube is placed outside the first outer wheel rim, and the pipeline of the first valve tube passes through the first outer wheel rim.

[0015] Furthermore, the second valve pipe of the second wheel rim is fixedly arranged in the second outer wheel rim, the air inlet end of the second valve pipe is placed outside the second outer wheel rim, and the pipe of the second valve pipe passes through the second outer wheel rim.

[0016] Furthermore, a plurality of bolt mounting holes are evenly distributed in the circumferential direction of the central mounting member.

[0017] Furthermore, the first outer rim and the second outer rim can cooperate to form a third rim.

[0018] The beneficial effects of the utility model are embodied in:

[0019] 1. In the utility model, the rim is installed and supported by installing the corresponding spoke assembly in the central mounting piece, so that the fixed installation between the central mounting piece, the spoke assembly and the rim forms a complete wheel hub. More specifically, since two sets of wheel rims are arranged on the outer side of the rim, the two sets of wheel rims are independently provided with corresponding valve tubes, so that two tires can be arranged on one wheel hub, and the two tires are tightly fitted, so that the two tires on one wheel hub can work normally and the cavity between the tires is independent. When one tire explodes, the other tire can still provide stable force support to the wheel hub to a certain extent, thereby reducing the safety risk caused by tire blowout or air leakage during driving of the car as much as possible; at the same time, since two tires that reduce the risk caused by wheel cover damage are arranged on a wheel hub with double wheel rims, there is no need to configure a spare tire for the car, which can save car space to a certain extent and also reduce the car's own weight.

[0020] 2. In the utility model, since the first wheel rim and the second wheel rim are arranged in the two groups of wheel rims, and the first wheel rim and the second wheel rim are arranged in sequence in the width direction of the rim body, the corresponding tires arranged in the width direction of the hub are subjected to uniform and balanced forces, thereby ensuring the stability of the working after the hub and the tire are matched; at the same time, relatively independent first wheel rim and second wheel rim are arranged to install the corresponding tires, making the installation of the tires more convenient and independent of each other without being affected.

[0021] 3. In the present invention, the first inner wheel rim and the second inner wheel rim are spaced apart so that the two sets of wheel rims are relatively independent, thereby ensuring that the wheel hub with double air cavities has good overall stability after installing two tires.

[0022] 4. In the present invention, by arranging the center mounting part, the spoke assembly and the rim as an integrated structure, the stability of the entire wheel hub in the working state can be enhanced as much as possible, making the wheel hub less likely to deform, and improving the safety performance of the automobile during the formation process.

[0023] 5. In the utility model, since a corresponding first valve tube is arranged in the first wheel rim, and the first valve tube is fixedly arranged in the first outer wheel rim, and the air inlet end of the first valve tube is placed on the outer side of the first outer wheel rim, the first valve tube arranged in this way is convenient for inflating the tire on the first wheel rim; similarly, a corresponding second valve tube is arranged in the second wheel rim, and the second valve tube is arranged on the outer side of the second outer wheel rim, which also realizes the convenience of inflating the tire in the second wheel rim.

[0024] 6. In the present invention, since the first outer wheel rim and the second outer wheel rim can be matched to form a third wheel rim, only one tire with a larger width can be installed on the entire wheel hub, thereby meeting the diversity of wheel hub usage.
