摘要

Hybrid electric vehicle (HEV) has been invented and developed over the past two decades. It is the promising solution for cutting down emission and reducing pollution besides electric vehicles. Since a series hybrid vehicle needs no transmission, the transmissions of parallel and series-parallel hybrid systems are studied nowadays. This paper presents a design approach for the configuration synthesis of series-parallel hybrid transmissions with the eight-link Ravigneaux mechanisms. The synthesis process subject to the concluded design consist of 7 mechanisms with eight members and twelve joints including the combination of two planetary gear trains. Then, by using the techniques of power and clutch arrangements, new series-parallel hybrid transmissions are synthesized with 27 clutchless hybrid systems and 27 corresponding series-parallel hybrid transmissions. A new hybrid transmission is selected as an example to demonstrate the feasibility of the synthesized configurations by analyzing the working principle with operation modes and power flow paths.

在過去的二十年間，混合動力車(HEV)正在被大量的研發，並被認為是電動車之外最具節能及降低汙染排放的交通工具，非常具有前景。對於各種傳動系統的研究而言，由於串聯式的動力混合並不需要傳動系統，因此並聯式及串並聯混合式的傳動系統則成了現今的研究焦點。本研究針對具八桿Ravigneaux式機構合成串並聯混合動力傳動系統進行分析及研究。其中，透過創意性機構設計方法，有系統的整合出七種具有8桿12接頭，包含兩組行星齒輪之可應用之傳動機構。再藉由動力源及離合器之配置技術，分別合成出27種串並聯式及27種離合器混合傳動機構。最後，為了證明本研究提出方法及合成系統的可行性，從中選擇一種新型混合動力傳動機構為例，說明工作原理、操作模式、與功流分析。
