  • Drive device for an electric bicycle powered electromotively and in a hybrid operating state involving muscular power
    Patent number: 10399636
    Abstract: A drive device for an electric bicycle includes a drive housing rigidly connected to a frame of the electric bicycle and a bottom bracket shaft arranged to rotate in the drive housing. First and second pedal cranks are arranged at respective ends of the bottom bracket shaft. The first and second pedal cranks are arranged to rotate with the bottom bracket shaft. A summing hollow shaft is rotatably supported in the drive housing. The summing hollow shaft is directly connected to the bottom bracket shaft via a cyclist's freewheel and, via a motor freewheel, to a gear driven by an electric motor. The summing hollow shaft is connected to a chain wheel for rotation therewith. A sensor assembly fixedly arranged in the drive housing includes a first torque sensor which cooperates with the bottom bracket shaft, and a second torque sensor which cooperates with the summing hollow shaft.
