Problems solved by technology
At present, the wheels of trucks and buses are made by steel wheel stamping process or aluminum alloy forging process. The wheels produced by this traditional process are heavy, consumable, and costly; especially steel wheels are easy to deform, poor heat dissipation, and low manufacturing accuracy. , short service life, and great potential safety hazards, so it has basically been eliminated in western countries
For wheels of different structures and sizes, the original forging method is inconvenient to produce, that is, the production cycle is long and the cost is high

Embodiment Construction
[0033] See figure 1 and figure 2 . The aluminum alloy wheel hub of the present invention includes a rim 1 and a spoke 2 arranged on the rim 1 , wherein the rim 1 is a central hollow structure formed by integral spinning of an aluminum alloy plate, and its edge is turned into a bent portion 11 . The spoke 2 is integrally connected in the hollow of the rim and separates the hollow part of the rim. It is a bowl-shaped structure formed by integral spinning of an aluminum alloy plate, and is provided with a ventilation hole 21 and a positioning hole 22. The positioning hole is located at The centers of the spokes are used for positioning, and the ventilation holes surround the positioning holes for ventilation. The rim 1 and the spokes 1 are connected in an inverted buckle-like step by spinning, and connected as a whole by friction stir welding.
[0034] In this specific embodiment, the rim 1 is formed by integral spinning of high-strength cold-rolled aluminum alloy 6061, the s...

The invention discloses an aluminum alloy hub for a super lightweight truck or passenger car, which comprises a rim and a spoke arranged on the rim, wherein the rim is a hollow structure made of an aluminum alloy plate through integral spin forming; the spoke is a hollow part made of an aluminum alloy plate through integral spin forming, and the spoke is connected in the hollow cavity of the rim and is isolated from the rim. The invention also discloses a manufacturing method of the super lightweight aluminum alloy hub for the truck or passenger car. The aluminum alloy hub can be applied to super lightweight trucks and passenger cars.
Description
technical field [0001] The invention relates to an aluminum alloy wheel hub, in particular to an ultra-lightweight truck and passenger car aluminum alloy wheel hub. Background technique [0002] Wheels widely used in motor vehicles, especially trucks and passenger cars, are composed of a rim on the outside and spokes connected to the inner surface of the rim. At present, the wheels of trucks and buses are made by steel wheel stamping process or aluminum alloy forging process. The wheels produced by this traditional process are heavy, consumable, and costly; especially steel wheels are easy to deform, poor heat dissipation, and low manufacturing accuracy. , The service life is short, and there are great safety hazards at the same time, so it has basically been eliminated in Western countries. For wheels of different structures and sizes, the original forging method is inconvenient to produce, that is, the production period is long and the cost is high. Contents of the inve...
