摘要

随着国家政策鼓励和油价的逐步攀升,降低汽车的油耗受到广泛的关注。汽车的油耗和传动效率密切相关,后桥在汽车的传动系统中起着重要的作用,而不同的润滑油对后桥的传动效率有着很大的影响。结合润滑油的黏度与齿轮啮合损失及搅油损失的相关研究进行了分析,根据相关的试验验证,得出黏度相对较低的润滑油对于提高后桥传动效率,降低整车油耗有着重要意义。

Abstract

As the national policy encourage to reduce the fuel consumption and oil prices rising gradually,to reduce fuel consumption of the vehicle is widely concerned.The fuel consumption is closely related to the transmission efficiency,and the rear axle plays an important role in auto transmission system and different lubricant has a great influence on the transmission efficiency of rear axle,the viscosity of the lubricant,the losses of gear meshing and churning losses are analyzed,a lot of experiments are conducted to investigate the influence of viscosity of lubricant on transmission efficiency of rear axle.It is found that relatively low viscosity lubricant contributes to improving the transmission efficiency of rear axle and makes an important significance on reducing vehicle fuel consumption.
