The invention relates to a torque sensor system and a power-assisted bicycle. The torque sensor system comprises a five-way assembly; the center shaft is arranged in the five-way assembly in a penetrating mode and can rotate around a rotating axis relative to the five-way assembly through the first bearing. A first movable gap is formed between the outer peripheral surface of the first bearing and the inner surface of the five-way component; the transmission piece is arranged between the first bearing and the strain gauge in the radial direction of the middle shaft; when the middle shaft drives the first bearing to move in the radial direction relative to the five-way assembly, the transmission piece can transmit acting force to the strain gauges. The strain gauge is not directly attached to the middle shaft any more, the first movable gap is formed between the outer surface of the first bearing and the inner surface of the five-way assembly, the transmission piece is arranged between the first bearing and the strain gauge, and movement of the middle shaft is transmitted to the strain gauge through the first bearing and the transmission piece. The torque sensor system can be connected with the main control circuit in a wired mode, so that the structure is simple, and the production cost is reduced.

    本发明涉及一种力矩传感器系统及助力自行车,包括:五通组件;第一轴承及中轴,中轴穿设于五通组件内,并能够通过第一轴承绕一转动轴线相对于五通组件转动;第一轴承的外周面与五通组件的内表面之间具有第一活动间隙;传递件及应变片,传递件在中轴的径向上设于第一轴承与应变片之间;中轴带动第一轴承相对于五通组件沿径向运动时,传递件能够传递作用力于应变片。应变片不再直接附着于中轴上,而是设置第一轴承的外表面与五通组件的内表面之间具有第一活动间隙,传递件设于第一轴承与应变片之间,中轴的运动通过第一轴承及传递件传递于应变片,如此,力矩传感器系统能够采用有线方式与主控电路连接,使得结构简单,降低了生产成本。
