摘要

駐車機構主要功能是當車輛停止時，駕駛人將齒輪箱排入P檔（Parking）時，啟動駐車機構做動，該齒輪箱便會被鎖住而使得車輛不再移動。然而駐車機構須滿足法規SAE J2208，其規定駐車機構於車輛行駛間做動時，車速6 km／h以下需能使駐車機構卡合鎖定，8－70 km／h以上則不得卡合鎖定以避免發生危險。本團隊原開發之二速變速箱已進入原型機測試階段，但原型機中仍缺少駐車機構，因此本文將完成一組符合法規SAE J2208之車用駐車機構，透過機構模擬軟體ADAMS驗證及有限元素軟體Abaqus強度分析，並實際應於本部門已開發之電動車用二速變速箱內。

The main function of a park lock mechanism is to lock the gear box when the vehicle stops and the driver puts the gear box control into the P (Parking) mode, to make the vehicle no longer move. However, the park lock mechanism must meets the SAE J2208 regulation, which stipulates that the park lock mechanism should be functional when the vehicle speed is below 6 km/h , and should not lock the gear box when the speed is above 8-70 km/h for safety reason. Although a two-speed gearbox developed by ITRI's team has entered prototype testing stage, its park lock mechanism is still lacking in its original design. Therefore this article describes the completion of a vehicle park lock mechanism that complies with SAE J2208. Through the motion analysis of mechanism simulation software ADAMS and strength analysis with finite element software Abaqus, the park lock mechanism was implemented into the two-speed gearbox for electric vehicles developed by ITRI.
