Latest Patents

Wan-You Cai holds a patent for a "Crank Treading Torque Detection Device for Electric Bicycle." This device includes a pre-set trading torque and a motor. The torque from the pre-set trading torque and the torque from the motor are respectively connected to a hollow tube mounted to an axle via a first one-way transmission device and a second one-way transmission device. The two respective powers are transmitted to a chainwheel by the hollow tube. A torque detection unit is connected to the hollow tube and located between the first and second one-way transmission devices. The power from the motor and the treading torques from the two ends of the axle do not affect each other. When the torque detection unit detects a torque that is higher than the pre-set trading torque, the motor is activated to provide power, and the detected torque is reduced to the pre-set torque. This innovation enhances the efficiency and performance of electric bicycles.
