Abstract

The invention relates to an aluminum alloy wheel for a heavy-duty vehicle, which has a rim and spoke integrated structure, wherein the sizes of the rim, spoke and connector of the aluminum alloy wheel are confirmed according to the existing tire standard, rim standard, inflating valve standard and mounting standard of a rim on a hub; the rim thickness and the spoke thickness of the aluminum alloywheel are confirmed according to an equivalent static force toughness equation rule; and the size range of a connecting filleted corner between the rim and the spoke is confirmed in order to achieve the purposes of reducing the stress concentration and improving the forming technical property. The aluminum alloy wheel for a heavy-duty vehicle is simply designed and calculated and is used for directly guiding the design and optimization of the aluminum alloy wheel. The structure of the aluminum alloy wheel is confirmed while the mechanical property indexes of the aluminum alloy wheel meeting the use demand are confirmed. The aluminum alloy wheel for a heavy-duty vehicle has the advantages of high intensity, high safety, light weight and excellent processing technical property, and is beneficial to promoting the application of the aluminum alloy wheel on the heavy-duty vehicle.

Description

technical field [0001] The invention relates to an aluminum alloy wheel for heavy vehicles, which is mainly used in the structural design of the aluminum alloy wheels for heavy vehicles to replace traditional steel wheels and reduce vehicle weight. Background technique [0002] Lightweight is one of the important directions of heavy vehicles and wheeled chariots, and it is the main way to save energy, reduce emissions and improve mobility. The use of light metal materials to replace steel is an important means to achieve lightweight. Aluminum alloy has low density, high specific strength and good processability, and is the best material for lightweight vehicles and wheeled chariots. [0003] The wheel is a rotating component that bears load between the tire and the axle. As the mobile part of heavy vehicles and wheeled chariots, there are many in the whole vehicle, but steel wheels are currently used. For example, for a 4×4 wheeled chariot, the wheels are made of Q235 stee...
