A freewheel hub comprising a magneto-elastic sensor and bicycle, pedelec, fast pedelec or e-bike comprising the freewheel hub |
摘要 |
A freewheel hub and a bicycle, pedelec, fast pedelec or e-bike comprising this freewheel hub is provided. The freewheel hub comprises a rotating hub shell for carrying a free running wheel. Torque is coupled to the rotating hub shell via a torque transmitting member. At least one magneto-elastically active region is directly or indirectly attached to or forms a part of the torque transmitting member in such a manner that the applied torque is transmitted to the active region comprising at least one magnetically polarized region. The magnetic polarization becomes increasingly helically shaped as the applied torque increases. A magneto-elastic sensor means having at least one magnetic field sensor is arranged proximate to the at least one magneto-elastically active region for outputting a signal corresponding to a torque-induced magnetic flux emanating from the magnetically polarized region. |
