力矩傳感器為電動輔助自行車中置電機系統關鍵零組件，用於感測踩踏力矩訊號，並透過控制器助力演算藉以提供騎乘者舒適的騎乘體驗。目前對於力矩傳感器之研究現況主要採用單邊感測之應變規式和雙邊感測之磁致伸縮式，分別存在著體積需求大和生產成本高的問題。本文提出一新型電動輔助自行車中置電機應變規式力矩傳感器結構模型，以雙邊感測方式進行結構設計，首先利用三維繪圖軟體建置一套中置電機力矩傳感器模型，該模型組成物包括:中置電機殼體、曲柄、曲柄心軸、滾珠軸承、超越離合器、力矩感測座、應變規、齒盤軸、大齒盤、鏈條及踏板。在力學模型中，騎乘者施一踩踏力於曲柄，踩踏力矩透過曲柄心軸及超越離合器輸出至齒盤軸進而提供大齒盤踩踏力矩輸出。於齒盤軸與力矩感測座之間設置滾珠軸承，並將力矩感測座鎖固於殼體上，藉以使齒盤軸可旋轉運動。而電機及齒輪透過另一超越離合器將輸出助力矩與踩踏力矩匯流於齒盤軸上，並進行綜合力矩輸出，在力矩輸出時力矩感測座將產生形變，該形變位置即為應變規黏貼處，透過應變規的電阻變化等效為力矩訊號，藉以提供電機感測產生輸出助力矩，其中力矩感測座的幾何為影響力矩訊號準確性的重要考量，因此本文主要在於進行不同力矩感測座幾何設計，利用穩態結構分析軟體進行之力矩傳感器系統應力及應變分析，將曲柄上的踩踏力及大齒盤上的鏈條作用壓軸力作為模擬力矩傳感器受力之邊界設定，在滿足力矩感測座材料(鋁合金)疲勞強度條件下獲得最大應變及應變方向，其中，應變與綜合輸出力矩呈線性關係，線性可靠度於90%以上，進而提供應變規黏貼位置、方向及數量依據，藉以完成新型電動輔助自行車中置電機應變規式力矩傳感器結構之研究。.

520 3 $a The torque sensor is a key component of the mid-mounted motor system of an electric assisted bicycle, which is used to sense the pedalling torque signal and to provide the rider with a comfortable riding experience through the controller's power algorithm. Currently, the torque sensors are mainly of strain gauge type with one side sensing and magnetostrictive type with two sides sensing, which have the problems of large size requirement and high production cost respectively. In this paper, we propose a new structural model of the mid-motor strain gauge torque sensor for electric-assisted bicycles, which is designed with bilateral sensing. Firstly, we use three-dimensional drawing software to build a model of the mid-motor torque sensor, and the components of the model include: mid-motor housing, crank, crankshafts, ball bearing, overrunning clutch, torque sensing bearing support, strain gauge, chain wheel shaft, chain wheel, chain and pedal. Pedals. In the mechanics model, the rider applies a pedalling force to the crank, and the pedalling moment is transmitted through the crankshaft and overrunning clutch to the gearbox shaft, which in turn provides the output of pedalling moment to the gearbox. A deep groove ball bearing is placed between the chain wheel shaft and the torque sensing bearing support, and the torque sensing bearing support is locked to the housing to allow the chain wheel shaft to rotate. The motor and gear through another beyond the clutch will output the auxiliary torque and pedal torque convergence in the chain wheel shaft, and the integrated torque output, in the torque output torque sensing bearing support will produce deformation, the deformation position that is the strain gauge adherence, through the strain gauge resistance change is equivalent to the torque signal, in order to provide the motor to sense the generation of output auxiliary torque, which the geometry of the torque sensing bearing support for the impact of torque signal accuracy is important considerations, therefore, this paper focuses on the torque sensing bearing support, which is the most important factor to be considered in this paper, is the torque sensing bearing support. Therefore, this paper mainly focuses on the geometrical design of different torque sensors and the stress and strain analysis of the torque sensor system using the static structural analysis software. The pedal force on the crank and the chain pressure on the gearbox are used as the boundary settings of the simulated torque sensor force, and the maximum strain and strain direction are obtained under the condition of satisfying the fatigue strength of the torque sensing bearing support material (aluminium alloy), wherein the strain and integrated output torque are linearly proportional to the output torque, and the strain and integrated output torque are linearly proportional to the output torque of the motor. The strain is linearly related to the combined output torque, with a linear reliability of over 90%, which further provides the position, direction, and quantity of the strain gauge to be adhered to, in order to complete the research on the structure of a new type of strain gauge torque sensor for the mid-mounted motor of an electric-assisted bicycle..
