Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy wheels, and more specifically to a high-strength forged aluminum alloy wheel. Background Art

[0002] The wheel is a cylindrical component that is used to support the tire inside the tire and is centrally assembled on the axle. In order to meet the functional and market needs, aluminum alloy wheels have a variety of structural designs such as integral and multi-piece combinations. At present, the main production methods of aluminum alloy wheels are casting, forging, stamping and spinning. The manufacturing of aluminum alloy wheels in my country is still dominated by low-pressure casting. The manufacturing technology of aluminum alloy wheels is constantly developing. In order to improve its performance, it is now developing in the direction of extrusion casting (liquid die forging) and semi-solid die forging.

[0003] The shortcomings of the prior art: Since the vehicle will generate friction during driving, the wheels will wear and heat up. Excessive temperature will easily cause the wheels to deform, causing greater wear and tear. After long-term use, it will easily affect the normal use of the vehicle. The wheels in the prior art are usually made using traditional methods, pouring the molten metal solution into a mold, cooling it and then grinding it to complete the production. Therefore, the wheel strength is relatively low, which affects the service life of the wheel. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a high-strength forged aluminum alloy wheel to solve the problems existing in the above-mentioned background technology.

[0005] The utility model provides the following technical solution: a high-strength forged aluminum alloy wheel, comprising a rim, wherein the outer surface of the rim is fixedly connected with an outer wheel rim all around, the end of the outer wheel rim close to the rim is fixedly connected with a bead seat, one end of the rim is provided with an air hole, the inner wall of the rim is fixedly connected with an inner wheel rim, a plurality of spokes are fixedly connected with an annular array on the inner wall of the inner wheel rim, a wheel center assembly is fixedly connected between the plurality of spokes, and a plurality of heat dissipation holes are provided with an annular array on the top end of the inner wheel rim.

[0006] Preferably, the spokes are arranged in an arc shape.

[0008] Preferably, one end of the spoke away from the rim is fixedly connected to the outer surface of the central axis.

[0009] Preferably, the rim, outer wheel flange, bead seat, inner wheel flange, spokes and wheel center assembly are manufactured using a forging process.

[0010] Preferably, the outer surfaces of the rim, outer wheel flange, bead seat, inner wheel flange, spokes and wheel center assembly are uniformly covered with a protective coating.

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model ensures the stability and firmness of tire installation by providing a bead seat. Since the wheel will generate friction during high-speed driving, causing the wheel to heat up, the heat dissipation effect of the wheel is increased through the heat dissipation holes to avoid deformation or increased wear of the wheel caused by excessive temperature. At the same time, the arc-shaped spokes are provided to reduce the resistance generated when the wheel rotates and reduce the friction generated by the rotation of the wheel.

[0013] 2. The utility model adopts a forging process for the wheel rim, outer wheel flange, bead seat, inner wheel flange, spokes and wheel center assembly. The forged aluminum alloy wheel is made of high-strength aluminum alloy material. Compared with ordinary wheels, it has higher hardness and lighter weight. At the same time, the forged aluminum alloy wheel has better heat dissipation and higher dimensional accuracy, which can reduce tire wear and has higher load-bearing capacity. At the same time, a protective coating is covered on the outer surface of the wheel, which improves the corrosion resistance of the wheel and increases the service life of the wheel.

[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The high-strength forged aluminum alloy wheel involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0020] The utility model provides a high-strength forged aluminum alloy wheel, such as Figure 1 As shown, it includes a rim 1, an outer wheel flange 2 is fixedly connected to the outer surface of the rim 1 all around, and a bead seat 3 is fixedly connected to one end of the outer wheel flange 2 close to the rim 1, and the stability and firmness of the tire installation are guaranteed by the bead seat 3. An air hole 4 is opened at one end of the rim 1, and the installation of the air valve on the tire is convenient through the air hole 4. An inner wheel flange 5 is fixedly connected to the inner wall of the rim 1, and the stability of vehicle driving is guaranteed by the outer wheel flange 2 and the inner wheel flange 5, and the wear of the tire is reduced. A plurality of spokes 6 are fixedly connected to the inner wall of the inner wheel flange 5 in an annular array, and a wheel center assembly 7 is fixedly connected between the plurality of spokes 6. A plurality of heat dissipation holes 8 are opened in an annular array at the top of the inner wheel flange 5. Since the wheel generates friction during high-speed driving, which causes the wheel to heat up, the heat dissipation effect of the wheel is increased through the heat dissipation holes 8 to avoid deformation of the wheel or increased wear caused by excessive temperature.

[0021] Further, such as Figure 2 As shown, the wheel center assembly 7 includes a central axis 71, and a wheel center body 72 is fixedly connected to the inner wall of the central axis 71. A plurality of bolt holes 73 are fixedly connected to the top of the wheel center body 72 in an annular array. Bolts are installed through the bolt holes 73, which facilitates the installation of the wheel with bolts. A central hole 74 is opened at the central axis of the wheel center body 72, and a decorative hole 75 is opened in an annular array at the top of the wheel center body 72. The position of the central axis of the wheel is ensured through the central hole 74, thereby ensuring the stability of the wheel.

[0022] Further, such as Figure 3 and Figure 4 As shown, one end of the spoke 6 away from the rim 1 is fixedly connected to the outer surface of the central axis 71 to form a skeleton supporting the wheel and provide necessary support for the tire. The spoke 6 is arranged in an arc shape to reduce the resistance generated when the wheel rotates and the friction generated by the wheel rotation, thereby improving the speed and comfort of the vehicle. At the same time, it withstands the driving force when turning to ensure the performance of the vehicle.

[0023] Furthermore, the rim 1, the outer wheel flange 2, the bead seat 3, the inner wheel flange 5, the spokes 6 and the wheel center assembly 7 are manufactured using a forging process. The forged aluminum alloy wheel is made of high-strength aluminum alloy material. Compared with ordinary wheels, it has higher hardness and lighter weight. At the same time, the forged aluminum alloy wheel has better heat dissipation and higher dimensional accuracy, which can reduce tire wear and has a higher load-bearing capacity. Appropriate manufacturing process and material selection can improve the stability of the vehicle and ensure safe and stable driving under various road conditions. The outer surfaces of the rim 1, the outer wheel flange 2, the bead seat 3, the inner wheel flange 5, the spokes 6 and the wheel center assembly 7 are evenly covered with a protective coating. Since the wheel is exposed to the external environment for a long time and is exposed to rain, etc., the corrosion resistance of the wheel is improved by the protective coating, thereby increasing the service life of the wheel.

[0024] The working principle of the utility model is as follows: firstly, a forging manufacturing process is adopted to manufacture the components such as the rim 1, the outer wheel rim 2, the bead seat 3, the inner wheel rim 5, the spokes 6 and the wheel center assembly 7, and a suitable shape is designed according to the needs of the vehicle. The forged aluminum alloy wheel adopts a high-strength aluminum alloy material, which has higher hardness and lighter weight than ordinary wheels. At the same time, the forged aluminum alloy wheel has better heat dissipation and higher dimensional accuracy, which can reduce tire wear and has higher load-bearing capacity. Appropriate manufacturing process and material selection can improve the stability of the vehicle and ensure safe and stable driving under various road conditions. After the manufacturing is completed, a protective coating is evenly covered on the outer surfaces of the components such as the rim 1, the outer wheel rim 2, the bead seat 3, the inner wheel rim 5, the spokes 6 and the wheel center assembly 7. Since the wheel is exposed to the outside for a long time, the wheel will not be damaged. Environment, contact with rain, etc., the corrosion resistance of the wheel is improved by the protective coating, and the service life of the wheel is increased. During use, the stability of the vehicle's driving is ensured by the outer rim 2 and the inner rim 5, while reducing the wear of the tire. The stability and firmness of the tire installation are ensured by the bead seat 3. The wheel is installed with bolts through the bolt holes 73. The spokes 6 are fixedly installed between the inner rim 5 and the center axis 71 to form a skeleton to support the wheel and provide necessary support for the tire. The arc-shaped spokes 6 reduce the resistance generated when the wheel rotates, reduce the friction generated by the rotation of the wheel, and ensure the performance of the vehicle. Since the wheel generates friction during high-speed driving, the wheel heats up. The heat dissipation effect of the wheel is increased through the heat dissipation holes 8 to avoid wheel deformation or increased wear caused by excessive temperature.
