Abstract (en)

[origin: WO9930960A2] The invention relates to an electric motor-driven supported muscular power driven drive mechanism in which the torque is measured by a torque sensor (35). Said sensor is centrally arranged in the area of the pedal axle (1) in the drive mechanism. The torque sensor is a magnetic pole type and has essentially band-shaped magnet poles (43, 53) which are displaced against one another by the torsion of a torsion section (39), whereby a magnetic value of the sensor (35) changes. As a result, a compact drive mechanism can be produced which permits a precise measurement of the muscular power torque. The sensor can be compactly constructed with the band-shaped magnet poles and can be easily produced.
