Abstract :
In recent years, because it has advantages in control accuracy, an electric-powered later torque-vectoring differential has become a hot topic. And the design of mechanism and the characteristics of electric-powered later torque-vectoring differential need farther research. This paper uses the velocity diagram represent all the type of simplest E-TVD which is composed of five elements with two degrees of freedom and analysis the revolution speed and the torque relation of each type.. Finally, compare the revolution speed of element C and torque amplification factor G of each type, the best mechanism is evaluated from the differences in the characteristics.
