MANUALLY OPERATED TRAVELLING VEHICLE WITH AUXILIARY POWER

摘要

A manually operated travelling vehicle with an auxiliary power device, which can detect a rotating torque applied to a rotating crank shaft (40) in non-contact manner. Supported on a body (15) is a manually operated prime mover wheel (5). A rotating coil (201) is provided coaxially on the prime mover wheel (5). A variable impedance device (202) is electrically connected to the rotating coil (201) such that impedance changes depending upon a load applied to the prime mover wheel (5). A stationary coil (101) is fixed to the body (15) to be coaxial with and spaced from the rotating coil (201) with a predetermined interval therebetween and is electromagnetically connected to the rotating coil (201). A detection circuit (109) is connected to the stationary coil (101) to detect a change in current or voltage applied to the stationary coil (101) from the rotating coil (201) in accordance with an impedance change in the variable impedance device (202). A control unit (130) controls a power source for the auxiliary power device on the basis of an output value issued from the detection circuit (109).
