摘要

汽车传动系统效率的优劣直接影响整车油耗

传动系统中变速箱的传动效率是很重要的一环

通过研究对比不同种类的润滑油及润滑油添加剂对传动系统的影响

对汽车润滑油的选用提供一种参考方案。实验表明

添加黏指剂能改善油品的黏温特性

传动效率的高低

与润滑油的黏度指数相关;转速越高

传动效率越高

但当转速过高

效率反而出现下降

是由于搅油功率损失所占比率超过润滑油对传动系统效率的贡献率。

Abstract

The efficiency of automobile transmission system would directly affect the vehicle fuel consumption

the efficiency of transmission plays an important role in the transmission system

by studying the effects of different contrast of lubricating oil and additive on the transmission system

a reference scheme selection of automobile lubricating oil is provided.The experiment shows that added the OCP could pronounced improve the viscosity-temperature property

the transmission efficiency associated with the viscosity index

efficiency is improved with the speed increased

but when the speed is too high

the efficiency decreased

the reason is that oil mixing power losing ratio contributed more than oil on transmission efficiency rate.
