A Study of Variable Speed Transmission with Combined Planetary Gear Train : 5th Report, Analysis of Input Power Division Type Transmission

Abstract

A new type of a mechanical variable speed transmission, which consists of a 2K-H type differential gear and a HST unit, is devised. The pattern of this transmission is replaced with a combined planetary gear train system. Through a theoretical analysis of the system, it is confirmed that the power circulation is occurring in the system. And it is made possible to realize a new highly efficient transmission only by controlling the quantity of power flow.
