汽车用铝合金副车架成形工艺及应用现状
|
摘要
汽车轻量化是实现节能减排的重要途径,零部件的"以铝代钢"仍然是当前汽车行业实现轻量化的主要手段。副车架作为汽车底盘悬挂系统中的重要结构件,将其铝制化可大大提高汽车轻量化程度。本中简要介绍了铝合金副车架的成形工艺及其应用现状,涵盖了铸造成形、液压成形、冲压成形+挤压成形+焊接、铸造成形+挤压成形/冲压成形+焊接和钢铝连接5种主流的成形方式,并对这些成形工艺的优缺点进行了对比分析。
Lightweight automotive application is an important way to achieve energy saving and emission reduction. Instead of the steels, aluminum alloys used as structural materials for lightweight components become more and more popular in the automotive industry. Subframe is an important structural part in automotive chassis suspension system, and application of aluminum alloy subframes exhibit considerable weight saving. This paper provides an overview of major forming processes of aluminum alloy subframes and their applications, which includes casting, hydroforming, punching+extruding+welding, casting+extruding/stamping+welding, and joining of steel with aluminum. Furthermore, the advantages and disadvantages of those forming processes are also discussed.
