摘要


本研究欲設計一新式電動代步車之防滑差速器,以六連桿七接頭之機構實現本設計。設計特色在於使用電磁閥驅動肘節機構、槓桿機構,並推動錐形體襯套與行星架嚙合,設計出符合小施力大效果,達到兩行星齒輪轉速同步,使左右車輪轉速一致避免打滑,達到防滑差速之效果。本研究使用簡易機構,整體構造簡單、易於加工,故製造技術相對簡單且成本低廉,而現今習知差速器之設計大部分離合器皆由齒形嚙合作動,本研究利用錐形體襯套嚙合行星架為一漸進式耦合動作,有益於延長機件壽命。本研究針對各種類型之防滑差速器進行專利及相關文獻蒐集,依實施方式加以歸類整理並分析,並依據設計條件擬定機構類型。本研究使用CAD軟體繪製防滑差速器之3D模型,並使用CAE軟體進行動態模擬與分析,擬定具有足夠強度之模型尺寸,以完成一新式電動代步車之防滑差速器。本研究之相關成果已提出專利 申請。

This research designs an electrical-scooter anti-slip differential by using six-link seven-joint mechanism. Its design characteristic includes using solenoid to drive toggle mechanism, lever mechanism, and conical lining to achieve the purpose of an anti-slip differential. This research adopts simple mechanisms which is easy to manufacture and low-cost. Today’s differentials generally employ gear transmission, while this research use conical lining to engage the planet arm gradually to improve its durability. This research collected and analyzed all relevant literatures, determined the types of mechanisms according to the design conditions. This research constructed and analyzed 3D computer model by using CAD and CAE software to determine the model sizes of a new electrical-scooter differential with necessary strength. The results of this research were filed for patent application.
