  • Transmission for electric bicycles for detecting a torque and related method for electric bicycles for detecting a torque
    Patent number: 8939247
    Abstract: A transmission for electric bicycles to detect a torque applied to a pedal crank shaft, includes a pedal crank shaft upon which the torque acts, a hollow shaft configured to connect to an output, through which the pedal crank shaft extends coaxially, and which is supported rotatably with respect to the pedal crank shaft, a sensor shaft offset in parallel with respect to the pedal crank shaft and a force sensor connected to the sensor shaft. The transmission includes a drive-side sensor transmission and an output side sensor transmission. The drive-side sensor transmission connects the pedal crank shaft to the sensor shaft and the output-side sensor transmission connects the sensor shaft to the hollow shaft, which is configured to be connected to an output, and the drive-side sensor transmission has a gear ratio which differs from the gear ratio of the output-side sensor transmission. A corresponding method is also described.
