摘要: | 車輛的傳動系統可以與內燃機、電動機等多個動力元件搭配運作,且車輛的傳動系統也可以具備多種構型以滿足各種需求。本研究旨在發展此類多動力多構型傳動系統的理念設計;首先,使用功能動力圖論方法分析現有的多動力多構型傳動系統,然後提出三種基本元素並擬定基本元素的候選位置作為合成工作的基礎。本研究以一至五個元素合成各種並聯構型、串聯構型與雙電機構型並整理為構型圖集,接著找出所有具備所需構型的傳動系統,例如有十種CCCC四離合器傳動系統可提供六個並聯構型、兩個雙電機構型及一個power-split構型;且有十三種CCCCC五離合器傳動系統可提供九個並聯構型、兩個雙電機構型及一個power-split構型。此外,為了避免構型與構型之間的切換需開關過多個離合元件,本研究亦發展構型切換圖論方法將離合元件的切換關係圖像化以輔助設計工作的進行。為了展現本理念設計工作的效果,文末初步發展一個新穎的CCCC四離合器傳動系統及一個新穎的CCCCC五離合器傳動系統,這些傳動系統集各種構型的優點於一身以兼顧性能與節能。綜上,本研究提出一種多動力多構型傳動系統之理念設計方法並以兩個新的傳動系統展現設計成果,盼文中較為不同的概念與想法可供後續研究參考。 A vehicle transmission may operate with more than one propulsion unit such as an internal combustion engine and two electric machines, and the transmission may have several configurations to achieve various requirements. This study is aimed to develop conceptual designs of this kind of transmissions. To begin with, existing multi-propulsion multi-configuration transmissions were analyzed by the Function Power Graph Method. Then three basic elements and a candidate-location map were proposed for the following synthesis works. The atlas of parallel configurations, series configurations, and two-motor EV configurations were built with one to five elements. Next, the complete set of transmissions with required configurations was explored: It is identified that ten CCCC four-clutch transmissions provide six parallel configurations, two two-motor EV configurations, and one power-split configuration; thirteen CCCCC five-clutch transmissions provide four parallel configurations, two two-motor EV configuration, and one power-split configuration. In addition, to avoid excessive clutch shifting between adjacent parallel configurations, the Configuration Transformation Graph method was developed to visualize the relationship between each configuration and support the transmission designing works. To demonstrate this conceptual design process, a novel CCCC four-clutch transmission and a novel CCCCC five-clutch transmission were developed, they collect the benefits from different configurations, make the vehicle powerful and energy-efficient. In conclusion, this study proposed and demonstrated a conceptual design process of multi-propulsion multi-configuration hybrid transmissions. It could provide some alternative concepts for further research. |
