Analysis of the Characteristics of the Electric-powered Torque-vectoring Differential

近年来,由于电动转矩定向差速器在转矩定向方面的应用越来越广,电动转矩定向差速器成为研究的热点,但是针对电动转矩定向差速器的机构设计及其特性分析还需进一步的研究。本文采用速度图法表示出最简单的电动转矩定向差速器机构的所有类型,分析了各构型中各构件间的转速和转矩的关系。通过对各构型中需求的电机转速、电机转矩放大系数G的对比分析筛选出较优的构型。

Because of its more and more widely used in recent years, the electric-powered torque-vectoring differential has become the focus of research. However, the design and characteristics analysis of mech-anism need a further study. The relationship between the rotational speed and torque of each member is an-alyzed in this article by the speed diagram method to represent all types of the simplest-powered torquevectoring differential mechanism. And the relationship between the speed and torque of each component in configuration is analyzed. A better configuration is selected by comparing and analyzing the motor speed and torque amplification factor G in each configuration.
