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 with figure 2 . The aluminum alloy wheel hub of the present invention includes a rim 1 and spokes 2 arranged on the rim 1. The rim 1 is a central hollow structure formed by integral spinning and forming of aluminum alloy plates, and the edges thereof are turned into a bent portion 11. The spoke 2 is integrally connected to the hollow part of the rim and separates the hollow part of the rim. It is a bowl-shaped structure formed by integral spinning and forming of an aluminum alloy plate, and is provided with ventilation holes 21 and positioning holes 22. The positioning holes are located The center of the spoke is used for positioning, and the ventilation hole surrounds the positioning hole for ventilation. The rim 1 and the spokes 1 are connected by spinning to form an inverted stepped connection, and are connected as a whole by friction stir welding.

[0034] In this specific embodiment, the rim 1 is integrally spun from a high-strength cold-rolled aluminum...

Abstract

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 aluminum alloy wheel hub for ultra-lightweight trucks and buses. Background technique [0002] The wheels, which are widely used in motor vehicles, especially trucks and passenger cars, are composed of a ring of outer rim 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 have heavy weight, many consumables and high cost; especially steel wheels are easy to deform, poor heat dissipation, and low manufacturing accuracy. , The service life is short, and at the same time there are great safety risks, 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. Su...
