Lightweight magnesium-aluminum alloy assembled wheel

Abstract

The invention discloses a lightweight magnesium-aluminum alloy assembled wheel and relates to a wheel structure. According to the lightweight magnesium-aluminum alloy assembled wheel, the problems that the maintenance cost is high and the waste is generated due to the fact that the existing structure of the wheel is a rim and spoke integrated structure and the whole wheel is required to be changed if the wheel is damaged are solved. The lightweight magnesium-aluminum alloy assembled wheel comprises a rim, a spoke and a hub, wherein an annular boss is arranged on the inner side of the rim; positioning grooves and mounting holes are uniformly distributed in the annular boss along the circumferential direction and are used for being connected with the spoke; the hub and the spoke are integrated; a radial positioning spigot and a mounting hole are distributed in the outer edge of the spoke. According to the lightweight magnesium-aluminum alloy assembled wheel, the spoke made of a magnesium alloy is protected by a tire, and the exposed area of the rim on the outer side of the wheel is small, so that the possibility of scratch is reduced and the defect that the magnesium alloy is poor in corrosion resistance is overcome; the spoke is made of an aluminum alloy, and thus high strength is obtained; the rim and the spoke form an assembled structure and are connected by bolts, so that the rim and the spoke can be respectively changed after being damaged; the convenience in maintenance is realized, the scrappage of the whole wheel is avoided, the manufacturing process is greatly simplified, the die cost is reduced and the manufacturing efficiency is increased.

Description

technical field [0001] The invention relates to a new wheel structure, in particular to an assembled wheel made of lightweight materials magnesium alloy and aluminum alloy. Background technique [0002] At present, most of the wheels adopt steel stamping and welding, aluminum alloy casting or forging rim and spoke integral structure. During use, due to the large exposed surface of the outer side of the spoke, it is easy to be scratched and damaged by stones, which will affect the wheel. Due to the integrated structure of the traditional wheel rim and spokes, if the wheel is damaged, the entire wheel needs to be replaced, and the maintenance cost is high, resulting in unnecessary waste. In recent years, magnesium alloy casting or forging wheels have also been introduced, but due to the poor corrosion resistance of magnesium alloys, low casting yield, difficult forging processing and high cost, the promotion and application of magnesium alloys in wheels is limited. The wheel ...
