The invention provides a power-assisted bicycle transmission shaft sensor, and belongs to the technical field of booster bicycles, the power-assisted bicycle transmission shaft sensor comprises a five-way body, a pedal middle shaft is mounted on the five-way body, a ratchet male die is mounted on the pedal middle shaft, a ratchet female die is arranged on one side of the ratchet male die, and a bearing outer sleeve sleeves the right side of a thrust bearing. The right end of the bearing outer sleeve is elastically connected to the five-way body, a magnet is fixed to the outer side of the bearing outer sleeve, and a Hall sensor is installed on the inner side of the five-way body. The ratchet male die is matched with the inclined surface of the ratchet female die, so that the ratchet male die is subjected to the torque of the pedal middle shaft; the ratchet wheel female die can be pushed to move in the axis direction of the pedal middle shaft, so that the magnet is pushed to move beside the Hall sensor, and the controller controls motor output of the moped according to a return signal of the Hall sensor, so that output torque of the motor corresponds to torque at the pedal plate in time; therefore, the power-assisted bicycle can accurately output electric power.
本发明提供助力自行车传动轴传感器,属于助力车技术领域,包括有五通本体,所述五通本体上安装有脚踏中轴,所述脚踏中轴上安装有棘轮公模,所述棘轮公模一侧设有棘轮母模,所述推力轴承右侧套设有一轴承外套,该轴承外套右端弹性连接于所述五通本体,该轴承外套外侧固定有一磁铁,所述五通本体内侧安装有霍尔感应器,本发明通过棘轮公模与棘轮母模的斜面配合,使得棘轮公模受到脚踏中轴的力矩并转动时,可以推动棘轮母模沿脚踏中轴的轴线方向移动,从而推动了磁铁在霍尔感应器旁的移动,控制器根据霍尔感应器的回传信号来控制助力车的马达输出,使得马达的输出扭力与脚踏板处的扭力即时对应起来,使得助力车可以精准地输出电力。
