摘　　要：以节能减排为目的,以某甩挂运输牵引车为研究对象进行轻量化设计。采用盘式制动器、少片簧等新技术;针对轮辋、变速器壳体、油箱、散热器、接头等采用铝合金与尼龙等新材料;采用单层纵梁、短轴距等新结构以及轻量化驱动桥。最终,使该牵引车的整备质量降至8 200 kg以下。经过有限元分析、台架试验及整车可靠性试验,验证了所采用轻量化设计方案的可行性。For the purpose of energy saving and emission reduction, lightweight design is carried out for a semi-trailer tractor for drop and pull transport. Using new technologies like disc brake and few-leaf spring ere, and new materials such as aluminum alloy and nylon, etc for wheel rim, transmission case, fuel tank, radiator, joints, etc, and new structures like single layer side rail and short wheelbase, and new lightweight drive axle, curb weight of this tractor is reduced below 8 200 kg. The lightweight design is verified by FEA, bench test and vehicle reliability test.
