Manually operated travelling vehicle with auxiliary power

Abstract

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