Abstract

The invention discloses a high-hardness, high-strength and high-toughness aluminium alloy which comprises the components: 7.36-10.21wt% of zinc, 2.18-3.56wt% of magnesium, 1.9-2.8wt% of copper, 0.15-0.40wt% of zirconium, 0.12-0.36wt% of iron, 0.05-0.45wt% of silicon, 0.01-0.03wt% of erbium / lanthanum / cerium, and the balance aluminum and unavoidable impurities. The invention also relates to a preparation method of the high-hardness, high-strength and high-toughness aluminium alloy and a preparation method of a high-hardness, high-strength and high-toughness synchronizer toothed ring. Through the improvement on smelting and heat treatment technologies, the prepared aluminium alloy has excellent mechanical properties such as high hardness, high tensile strength and high yield strength; and when the aluminium alloy is used to prepare the synchronizer toothed ring, the surface strength and the abrasive resistance of the prepared synchronizer toothed ring are improved greatly, and the quality and service life of the synchronizer toothed ring can be improved and increased.

Description

technical field [0001] The invention relates to an aluminum alloy, in particular to a high-hardness, high-strength, high-toughness aluminum alloy and its manufacturing method and a manufacturing method of a synchronizer gear ring. Background technique [0002] Aluminum alloy is a general term for aluminum-based alloys. The main alloying elements include copper, silicon, magnesium, zinc, and manganese, and the secondary elements include nickel, iron, titanium, and lithium. The content, ratio, and impurity content of the main elements in the alloy It has a great influence on the performance of the finished alloy. [0003] Automobile synchronizer is a key component of mechanical gear transmission. Using synchronizer to shift gears is light and flexible. When shifting gears, the gears and shafts are not impacted, which prolongs the life of the transmission, reduces labor intensity, and improves the power and fuel economy of the car. The synchronizer is responsible for shifting ...
