摘　　要：根据汽车理论与变速箱理论原理,浅析整车传动系统效率研究对象,确定传动系阻力损失主要来源于变速箱、驱动轴、轮毂轴承和制动器四个方面,详细分析了这四个方面的阻力产生机理,基于某款成熟车型,针对其变速箱阻力损失、驱动轴阻力损失、轮毂轴承阻力损失以及制动拖滞力损失提出合理的优化方案,将该车型优化前后的NEDC工况下的百公里油耗进行对比验证,最终传动系内阻优化方案可实现NEDC工况下节油2.06%的效果。According to automobile theory and transmission theory,research object of vehicle transmission system efficiency is analyzed.The resistance loss of transmission system mainly comes from four aspects:gearbox,drive shaft,hub bearing and brake.The resistance mechanism of these four aspects is analyzed in detail.Based on a mature model,for the transmission resistance loss,drive shaft resistance loss,hub bearing resistance loss and brake drag loss,reasonable optimization schemes are proposed.And the fuel consumption of 100 km under NEDC conditions before and after the optimization of the vehicle model is compared and verified.Finally,the optimization scheme of internal resistance of transmission system can reduce the fuel consumption of NEDC by 2.06%.
