摘要

使用輪內馬達可以簡化車輛傳動系統，在目前電動車發展上被視為一個主要方向，但相對使簧下質量增加的結果會讓車輛動態性質有明顯影響，所以本研究將對發展一種針對輪內馬達的新型懸吊系統。本研究中先以三自由度懸吊系統配合動態減振理論為基礎，在簧下元件間增加輪內馬達懸吊系統，稱之為第二懸吊。其次，為了在車輪內配置第二懸吊概念，先對目前已有的系統進行拓樸分析，加入輪內馬達與第二懸吊等次系統且進行排列組合，便發展出多種具有轉移簧下元件質量的機構拓樸設計。接著，利用設計方法將多種機構拓樸設計方案，根據次系統的特性，轉換及發展多種機構概念設計。最後，本研究將以一設計範例，包含選定適當的目標車與輪內馬達，接著概念設計與細部設計，以說明及展示輪內馬達懸吊的完整設計方法。本研究針對輪內馬達懸吊系統進行其車輛動態特性探討，及發展系統化的設計方法，對輪內馬達之應用及實現應有助益。

Using the In-Wheel motors may simplify the transmission systems of the vehicles, so it will be a main direction in the electric vehicles development. But the In-Wheel motor build-in the the unsprung mass, becoming the heavy unsprung mass have the obvious influence of vehicles dynamic. So this study analyzes and designs of the suspension systems for In-wheel motors. Firstly, in this study using 3-D.O.F Suspension Systems based on the Dynamic Vibration Absorbers Theory, the suspension of in-wheel motor build-in the unsprung mass be called the second suspension. Then in order to realizing the the second suspension, topology analysis of the usual suspension system adds on the second suspension and a coupling of sub-systems, then developes some kinds of topological design. Next to design method functional diagram topology analysis obtained plan, according to sub-systems characteristic, to transform and develope many kinds of organization conceptual design of system. Finally, this study by a design model will contain in designation suitable car and the in-wheel motor, then the conceptual design and detailing of system will show integrity design method of suspension systems of In-Wheel motors. This study in In-wheel motor suspension system carries on its vehicles dynamic characteristic discussion, and the development systematization design method, let the application of and realization in-wheel motors helpfully.
