三輪側傾機車之防側傾機構概念設計

本研究藉由現有前二後一之三輪側傾機車設計一防側傾裝置，使騎士在轉彎回正時提供輔助力，減輕騎士操作負擔。透過參考車種規劃出機構設計空間，參考Scotch Yoke概念設計一防側傾裝置，並以油壓缸作為機構出力的致動器，應用摩托車動力學計算機車過彎及傾倒所需扭矩，計算出機構所需出力以選出適合的油壓缸，機車回正時機由側傾角與側傾角加速度作為判斷來控制機構出力時間，最後進行Simpack路線模擬驗證。Simpack分析模型與實際車輛重心位置比對差異1%以下確認結構性質一致，最後進行動態模擬路線驗證，其結果顯示於高速時可有效降低轉向扭矩，且能提高轉向時的靈敏性。

In the objective of this study, an anti-tilting device was designed by the existing three-wheeled tiltable motorcycle with two front wheels and one rear wheel, which enables the rider to provide assistance force when returning to the vertical position after a turning to reduce the rider's operating burden. Plan the mechanism design space by referring to the vehicle type, design an anti-tilting mechanism with reference to the Scotch Yoke concept, and use a hydraulic cylinder as the actuator of the mechanism. Using motorcycle dynamics to calculate the required torque, than we calculate the output of the mechanism for select a suitable hydraulic cylinder. The roll angle and roll acceleration of the motorcycle are used as judgments to control the actuation time of the mechanism. Finally, simulate and verify the result by Simpack. The difference between the Simpack analysis model and the actual vehicle's center of gravity position is less than 1% that confirmed the structural properties are consistent. The results show that the steering torque can be effectively reduced at high speeds and the steering sensitivity can be improved.
