Abstract
A torque sensor system for a pedelec includes an annular gear (), a planetary gear train (), a sun gear output shaft (), a pressure conversion device () and a signal processing component (). The annular gear (), the planetary gear train (), and the sun gear output shaft () are engaged in turn. The annular gear () is driven by the planetary gear train (), and an applied force signal is transmitted to the signal processing component () via the pressure conversion device () at an edge of the annular gear (). The applied force signal is converted to an electric signal by the signal processing component () and transmitted to a controller, so as to realize a torque feedback. As a result, a problem that a speed sensor is not applicable to a pedelec when climbing is solved; and a user will feel real and comfortable when riding.
