電動助行車動力系統之雛型設計與研發

本論文之目的有二：1.設計出電動助行車的齒輪傳動系統，與2.中置馬達倒踩剎車的機構設計(包括齒輪傳動系統)。首先收集與分析中華民國、中國大陸、美國、日本等各國電動自行車與中置馬達倒踩剎車機構的相關專利，並整理其專利之特色與優缺點，作為電動助行車齒輪傳動系統與中置馬達倒踩剎車機構設計時之參考。首先，解析現有的電動助行車的齒輪傳動系統，並分析與繪製出其機構簡圖。1.在電動助行車的齒輪傳動系統的設計中，本論文利用單級螺旋齒輪減速機取代現有齒輪傳動系統，並改變行星齒輪系的設計，並加入踏利感測器，完成電動助行車的齒輪傳動系統的設計。2. 在中置馬達倒踩剎車設計中，本論文利用將行星齒輪系、單向離合器、離合器、以及彈簧等設計成為倒踩剎車之機構；含馬達傳動檔位、腳踩前進檔位、以及倒踩剎車檔位。本研究成果將可提升台灣在電動助行車的研發能力，並提升產業競爭力。

There are two purposes of this thesis. 1. The design of gear transmission for electric assistant bicycle, 2. The design of reverse-pedal brake system for electric assistant bicycle (including gear transmission). First, collect and analyze the patents of gear transmission and reverse-pedal brake system of electric assistant bicycle in R.O.C., China, United States, Japan and other countries. Sort out the features, advantages, and disadvantages of these patents. First, dismantle the gear transmission of existing electric bicycle and draw its corresponding skeleton of gear mechanism. In the design of gear transmission for electric assistant bicycle, in this thesis, a single helical gear pair is used to replace existing gear transmission system. Change the design of the planetary gear train and joint torque sensor into the system to complete the gear transmission system of electric assistant bicycle. In the design of reverse-pedal brake system of electric assistant bicycle, in this thesis, planetary gear train, one-way clutch, clutch, and spring are used to design the mechanism of reverse-pedal brake system for electric assistant bicycle (including motor drive, foot drive, and reverse-pedal brake). The results of this thesis will enhance Taiwan's R & D capabilities industrial competitiveness of electric assistant bicycle.
