Abstract

The invention discloses a magnesium alloy wheel hub comprising a wheel center and a wheel rim; spokes are arranged between the wheel center and the wheel rim; in addition, the spoke comprises an inner arc edge and an outer arc edge; the inner arc edge comprises a fourth radian; a first radian is formed between the inner arc edge and the wheel center; a second radian is formed between the inner arc edge and the wheel rim; the outer arc edge is provided with a fifth radian; a third radian is formed between the outer arc edge and the wheel rim; the first to fifth radians R1, R2, R3, R4 and R5 satisfy the following value range:20mm<=R1<=30mm, 10mm<=R2<=15mm, 10mm<=R3<=15mm, 300mm<=R4<=310mm, and 330mm<=R5<=360mm. The advantages are that the magnesium alloy wheel hub can meet the application demands on stress.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a magnesium alloy wheel hub. Background technique [0002] With the prominent energy shortage and environmental pollution problems, lightweight has become the trend of vehicle development. On the other hand, as the demand for vehicles continues to increase, the metal materials such as steel and aluminum required by vehicles are also increasing day by day. According to statistics, the reserves of resources such as iron and aluminum in the world are only enough for 100-300 years, while in my country , the reserves of iron are not abundant, and the quality of bauxite is not high, so it is urgent to seek a new alternative material. [0003] Magnesium alloy, the lightest metal structural material known, has gradually become the main research object in the development of vehicle lightweight due to its many advantages. Compared with steel and aluminum, magnesium alloy has the follow...
