SENSOR DEVICE, DRIVING FORCE SUPPLEMENTING DEVICE USING THE DEVICE AND ZERO POINT ADJUSTING DEVICE FOR A TORQUE SENSOR FOR THE DRIVING FORCE SUPPLEMENTING DEVICE |
摘要 |
<p>A sensor device comprising a magnet (52) and a magnetic detection element (53), the sensor device further comprising a detection shaft (38a), a detection disc (59a) secured to the detection shaft, a magnetic piece (59b) secured to an outer circumferential edge of the detection disc, and a yoke (59c) disposed so as to hold the magnetic piece in a gap having a predetermined shape, the magnet and the magnetic detection element being secured to the yoke. The sensor device is applied to a driving force supplementing device for synthesizing a manual driving force and a motor driving force. The driving force supplementing device comprises a torque sensor (30), a vehicle speed detecting means (40) for detecting the running speed of the driving force supplementing device and a supplement power means using a motor (M). The vehicle speed detecting means (40) detects the running speed by the driving force supplementing device based on a rotating position signal obtained from a rotor rotating position detecting means. The torque sensor (30) comprises a mechanism for automatically adjusting a zero point by correcting an output voltage. <IMAGE></p> |
