<p>A torque sensing device (1) on rear axle and an electric bicycle are provided. The sensing device (1) has a sensor fixing seat (10) for a sensor (20) and a fixing sleeve (50) for a magnetic piece (30). The sensor fixed seat (10) can be integrally connected with the claw (2) of the electric bicycle. The fixing sleeve (50) can be integrally connected with the rear axle (3) of the electric bicycle. Because of the slip connection between the sensor fixed seat (10) and the fixing sleeve (50), the fixing sleeve (50) can move with the rear axle (3) by foot pushing, while the sensor fixed seat (10) and the claw (2) will remain stationary. Therefore, the state of the fixing sleeve (50) and the rear axle (3) will be sensed by the sensor (20) so as to start the electric motor for assisting the manual riding. Similarly, while the foot pushing off, the fixing sleeve (50) and the rear axle (3) will return to their original position, and the moving state disappears, thus the electric motor stops output.</p> |
