Embodiment Construction

[0029] figure 1 , Figure 2a The basic structure of the first embodiment of the wheel of the present invention is shown. The aluminum alloy wheel includes an aluminum alloy rim 1 and an aluminum alloy center disc 2 arranged in the inner ring of the rim. The rim is axially butted into a whole by the outer ring 5 and the inner ring 6, the rim 3 of the rim is turned over into a hollow structure, and the spokes 4 of the center disc are arranged into a hollow structure (see Figure 2b ), the central disc 2 is connected to the butt joint of the inner and outer rings.

[0030] In this example, see Figure 2a , Image 6 , Figure 7 , the rim is formed by two axial butt joints of the outer ring 5 and the inner ring 6, and the center disc 2 is connected to the butt joint of the inner and outer rings by friction stir welding. The butt joints of the inner and outer rings and the central disk are formed into stepped joints 8 . The wall thickness of the inner and outer rings can be ma...

Abstract

The invention discloses an aluminium alloy wheel, which comprises a wheel rim and a central disk arranged in the inner ring of the wheel rim. The wheel rim is an integral body consisting of an outer ring and the inner ring which are butted together axially; the wheel flange of the wheel rim is a hollow structure; the wheel spoke of the central disk is a hollow structure; and the central disk is connected with the butting part of the inner ring and the outer ring. The invention also discloses a method for producing the aluminum alloy wheel, namely adopting a spin forming method to make two sections of the wheel rim of the inner ring and the outer ring, and using a friction stir welding method to weld the wheel rim and the central disk into an integral body, wherein the position of the central disk in the wheel rim can be selected according to the requirement. Because the aluminium alloy wheel adopts the spin forming method and the 'hollow structure', half of materials can be saved, thus the wheel is light in weight, high in strength, beautiful in appearance, environment-friendly, and energy-saving. The structure and the process are suitable for mass production with high efficiency and low cost.

Description

technical field [0001] The invention relates to an aluminum alloy wheel, in particular to a hollow high-performance aluminum alloy wheel and a manufacturing method thereof. Background technique [0002] The aluminum alloy wheel, which is widely used in motor vehicles, especially for high-end cars, is composed of an outer rim and a center disk connected to the inner surface of the rim. At present, the wheels are made by casting process or forging process. The wheels made by this traditional process are heavy in weight, many consumables and high cost. For wheels of different structures and sizes, the production is inconvenient, that is, the production cycle is long and the cost is high. SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, the present invention provides an aluminum alloy wheel with high strength, light weight and beautiful appearance, and a manufacturing method thereof with high efficiency, environmental protection and energy savi...
