Abstract
The invention discloses a hub material, and particularly discloses a three-sheet aluminum-alloy forged hub material. The three-sheet aluminum-alloy forged hub material comprises chemical elements in percentage by mass as follows: 0.5-0.8% of Si, 0.2-0.4% of Cu, 0.1-0.3% of Mn, 0.9-1.2% of Mg, 0.1-0.3% of Cr, 0.2-0.4% of Zn, 0.1-0.6% of Ti, 0.1-0.4% of Re, at most 0.5% of Fe, at most 0.01% of Pb, and the balance of Al, wherein the content of other single element is at most 0.05% and the total content of other elements is at most 0.15%. By adopting the three-sheet aluminum-alloy forged hub material, the defect that the flexibility and the automatic fatigue recovery function of the existing aluminum-alloy forged hub made of an aluminum-magnesium-silicon alloy (alloy 6 series) material are unable to meet the technical requirement is solved; the three-sheet aluminum-alloy forged hub material disclosed by the invention has good malleability; and the flexibility and the automatic fatigue recovery function of the three-sheet forged hub made of the material are good, and the three-sheet forged hub is not fractured immediately even when encountering a big impact.
Description
Technical field
The present invention relates to a kind of hub material of taking turns, particularly a kind of three-plate aluminum alloy forged hub material.
Background technology
The quality of wheel and reliability quality are not only closely related with the safety of vehicle, and with automobile stationarity, comfortableness, safety operation close relation under steam.Thereby require the size and dimension precision of wheel high, good dynamic balance, fatigue strength height, perfect heat-dissipating, rigidity and good springiness.Along with the development of automobile, the class of automobile is become better and better, and car speed is more and more faster, and individual requirement is also more and more higher, so also more and more higher to the requirement of automotive hub.
Widely used in China's automobile is the conventional aluminium wheel hub, is an integral body that forms with die casting, and the shape of product is single, change parameter and the shape of wheel and must change mould; And what the conventional cast wheel hub adopted is the A356-2 aluminium, the A356-2 aluminium, and its stability and thermal diffusivity are also poor, and quality is also heavier simultaneously.
In order to solve the problems of the technologies described above, on the market a kind of three-plate aluminum alloy forged hub has appearred now, so-called three-chip type wheel hub, that wheel hub is resolved into anter, middle and rear panel, and then it is combined into a complete wheel hub, but it can satisfy again the basic parameter of all wheel hubs, as: the P.C.D size, C/B size and OFFSET etc., middle decorative pattern can personalized design, the automatization engraving.Therefore above-mentioned three-plate aluminum alloy forged hub is the representative of high-performance, high technology content in the present automotive hub, is the leading product in the international automobile wheel hub industry.This wheel hub all is far superior to the conventional cast wheel hub on intensity, quality, thermal diffusivity and profile.
The production of the normal employing of above-mentioned three-plate aluminum alloy forged hub 6 series (aluminium, magnesium, silicon) alloy material, but because the ductility of 6 series (aluminium, magnesium, silicon) alloy material itself not enough, so that retractility and the automatic fatigue recovery function of the three-plate aluminum alloy forged hub after producing also do not reach requirement.
Summary of the invention
The objective of the invention is provides a kind of ductility good three-plate aluminum alloy forged hub material in order to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the three-plate aluminum alloy forged hub material that the present invention is designed, its chemical ingredients: Si 0.5%-0.8%, Cu0.2%-0.4%, Mn0.1%-0.3%, Mg0.9%-1.2%, Cr0.1%-0.3%, Zn0.2%-0.4%, Ti0.1%-0.6%, Re0.1%-0.4%, Fe≤0.5%, Pb≤0.01%, other metal or nonmetal composition be single≤and 0.05%, total amount≤0.15%, the Al surplus is in quality %.The preferred 0.1%-0.3% of the mass ratio of Ti wherein.
The control of the adding of Re element and other element ratios in the proportioning of above-mentioned materials is so that ductility of the present invention is high.
The three-plate aluminum alloy forged hub material that the present invention obtains, its ductility is good, adopts the Three-plate forging hub assembling of this material produce to have good retractility and automatic fatigue recovery function, also can not rupture immediately even run into great bump.
