GDS-11 POWER FLOW OF DOUBLE LOOPED PLANETARY GEAR SYSTEM(GEAR DESIGN AND SYNTHESIS)

概要

論文の詳細を見る
The double looped planetary gear system (DLPS) is composed with two sets of the single looped planetary gear system (SLPS) that includes a planetary gear mechanism and a continuously variable transmission (CVT). Depending on occupied position of CVT inside DLPS, DLPS is divided to two types : exclusive CVT and inclusive CVT type. DLPS is possible to control output speed sensitively by CVT. and usable for a transmission of hybrid vehicles. Because DLPS has two loop circuits from the topological point of view, various types of power flow appear in the circuit. This paper deals with classification of the power flow type of DLPS. At first, the author introduces the characteristic diagram regarding to angular velocity of planetary gear mechanism, that explains classification of power flow of SLPS and speed variation range induced by CVT operation. Secondly considering dividing condition of power flow in a planetary gear mechanism, he intends to apply the diagram to DLPS and presents an extended diagram that shows combination of power flow of SLPS. Moreover, following explanation about the extended diagram, he presents a table showing whole type of power flow of DLPS. Finally a practical example of DLPS and its power flow are explained.
