The valve plate of the electronic throttle is controlled by the rotation of the shaft, and the rotation angle of the shaft is controlled by the shaft drive mechanism. The shaft drive mechanism is fixed on the shaft through a gear to drive the rotation. The gear has two extreme positions: "idle position" and "fully closed position" and "fully closed position". Usually, a one-way return torsion spring is installed on the gear to provide the gear with "fully closed-idle" and "fully open-idle" return force. During the processing and manufacturing process of the throttle gear, a mold needs to be used for production.
