Abstract

This newly invented the transmission system of differential gear is a transmission system that changes the power of engine and transmits it to an axle. Existing MT and AT have few steps of transmission, so they give a low fuel efficiency, and especially for AT, it's structure is too complicated, making it hard to increase a step of transmission, and the inefficient frictional power of V belt based CVT also limits the usage and it's complicated, so it has a low efficiency and performance. To complement the low fuel efficiency of existing transmission, in this invention, we increase the step of transmission easily than existing MT and AT, by using the differential gear, and it results in higher fuel efficiency.
