複合動力車底盤動力系統之設計研究
Research of Hybrid Vehicle Powertrains System Design
摘要
複合動力系統為結合兩種不同動力源來驅動車輛可區分為並聯式及串聯式，並聯式的優點在於兩個不同的雙動力源可個別單獨運轉輸出動力來驅動車輛，其能量運用率比較高，在燃油經濟性效率上使用並聯式複合動力系統較串聯式複合動力系統好。 本研究是將一台傳統引擎車輛改裝為複合動力車，保留原有的引擎動力源，加上馬達/發電機，配合逆向差速齒輪式動力整合分配機構做單/雙動力整合輸出，隨著車輛負載的變化，將動力維持在最佳運轉範圍，達到低油耗與低碳排放量的目的。本研究以電腦輔助設計(Computer Aided Design,CAD)軟體Solid Works進行設計，首先從量測實車尺寸做為空間配置的邊界條件，在電腦輔助設計軟體上繪製底盤零件並配合空間邊界條件，規劃整車配置空間，再進行支撐架設計，最後以軟體模擬裝配情況，以去除實際組裝可能產生的干涉問題，目標為車體結構最小改變，達到空間最佳化的運用，本研究亦使用工程輔助分析軟體(Computer Aided Engineering,CAE)對支撐架進行輕量化分析，以減低車重，提高整車的行車性能。

Hybrid system combines two different power source systems in order to drive vehicles. The most common ones are parallel and series Hybrid vehicles of the Parallel Hybrid Electric System Drive Train Design (PHES) to had better transmission efficiency. The benefit of PHES is to drive vehicles with two individual power sources. PHES’s rate of energy usage is better than Series Hybrid Electric System Drive Train Design (SHES). Also,PHES is better than SHES in Fuel economy. and urban and high ways. The purpose of the study was to remodel a traditional engine vehicle to a hybrid one. of In the design the power source of the original internal combustion engine, was remained a motor/power generator, ECVT, and coordinating with reverse differential gear type of power integration distribution mechanism to do a single/dual-power integrated output were added This hybrid used a CAD software,Solid Works. First of all,underbody dimension were measured,than chasis parts were draw and depend the availacle underbody space and the package layout was developed.Finally,interferences were checked and cleared. We tired to kept minimum body structure changes in order to achieve optimal use of space. This study also used secondary analysis of software engineering (CAE) to lightweight the support frames. to reduce vehicle weight, and to improve the vehicle's driving performance.
