摘要

The principle of improving the torque amplification factor of E-TVDs with six elements is illustrated in this paper. A velocity diagram is used to study speed and torque relationships. The results reveal that the torque amplification factor is the linear combination of the ratio of the differentials of the four elements and the ratio of planetary gear units, and its maximum value is easily more than 10. The E-TVDs with six elements are classified into three types, and there are six different configurations for each type. The torque amplification factor and the speed of interconnection between two planetary gear units are employed to evaluate the different characteristics of each E-TVD with six elements. The feasible configurations of a differential with four elements are also presented by the analysis of velocity level and planarity. This paper helps to further the understanding of the complex interconnection of the planetary gear units in E-TVDs with six elements and the differences of their characteristics.
