The invention belongs to bicycle power assisting devices, and particularly relates to a bicycle central motor pedal torsion sensor system. The system is characterized in that a crank (1) is connectedwith a central shaft core (2), the central shaft core (2) is connected with a one-way ratchet wheel (4), the one-way ratchet wheel (4) compresses a spring (5) arranged on the central shaft core (2), and the spring (5) acts on a crankset seat (6) and a crankset which are connected to a shaft sleeve (3) through a compression force. Crank treading and motor assisting are almost synchronous. The system is small in structural size, light in weight and convenient to install.

    本发明属于自行车助力装置,具体涉及一种自行车中置电机脚踏扭力传感器系统,其特征在于:曲柄(1)与中轴轴芯(2)相连,中轴轴芯(2)与单向棘轮(4)相连,单向棘轮(4)压缩设置在中轴轴芯(2)上的弹簧(5),弹簧(5)通过压缩力作用于连接在轴套(3)上的牙盘座(6)和牙盘。本发明踩踏曲柄、电机助力、几乎同步、结构体积小、重量轻、安装方便。
