Description

Technical Field:

[0001] The present invention relates to the technical field of wheel hub processing, and more specifically to a wire steel automobile wheel hub. Background Art:

[0002] Existing automobile wheel hubs are all forged wheel hubs, and their hub parts and rim parts are formed together. However, while increasing the rigidity strength, their resilience is poor, and during some driving processes, they are prone to breakage, and the effect is not ideal. Moreover, forged wheel hubs are heavy.

[0003] For wire steel wheel hubs, they are light in weight and good in resilience. However, generally, inner tires and outer tires are installed outside the rim, otherwise they are prone to air leakage, affecting the use effect. Summary of the Invention:

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a wire steel automobile wheel hub. It uses a plurality of first wires and second wires to connect the hub part and the rim part. The rim part can directly install a tubeless tire, which is convenient to install, has a good sealing effect, and ensures the use effect.

[0005] The solution for the present invention to solve the above technical problems is:

[0006] A wire steel automobile wheel hub includes a rim part and a hub part, and the hub part is located in the middle of the rim part.

[0007] At the upper part of the side plate part connected to the middle of the rim part, a plurality of upper obliquely connecting through holes extending upward at the outer end and downward at the inner end are formed. At the lower part of the side plate part connected to the middle of the rim part, a plurality of lower obliquely connecting through holes extending downward at the outer end and upward at the inner end are formed.

[0008] The hub part is in the shape of a cylindrical sleeve, and a central vertical through hole is formed in the middle thereof. Connecting obliquely through holes extending outward are formed on the inner side walls of the upper and lower parts of the central vertical through hole. A plurality of first wires extending downward at the outer end and upward at the inner end and a plurality of second wires extending upward at the outer end and downward at the inner end are alternately arranged between the hub part and the rim part. One end of the first wire is installed in the upper connecting obliquely through hole, and the other end is installed in the lower obliquely connecting through hole. One end of the second wire is installed in the lower connecting obliquely through hole, and the other end is installed in the upper obliquely connecting through hole.

Positioning grooves extending outwards are formed on the inner side walls of the outer ends of the lower obliquely connecting through holes and the upper obliquely connecting through holes. The elastic sealing sleeve body is located in the lower obliquely connecting through hole or the upper obliquely connecting through hole. The outer side wall of the elastic sealing sleeve body is pressed against the inner side wall of the lower obliquely connecting through hole or the upper obliquely connecting through hole.
