Neutral position detector for steering wheels having a first and second rotors with aligned slots
First Claim
1. A neutral position detector for detecting a predetermined position of a steering wheel, comprising:
- first rotor means rotating integrally with a steering shaft;
said first rotor including first means for detecting the predetermined position of the steering wheel;
second rotor means rotatably interlocked with said first rotor means;
power transmission means for driving said second rotor means by a predetermined rotation angle each time said first rotor means completes one revolution;
said second rotor means including second means for detecting the predetermined position of the steering wheel; and
sensor means for outputting a detection signal when said first detecting means is aligned with said second detecting means.

Abstract
A neutral position detector detects the neutral position of a steering wheel, and includes a first rotor which rotates integrally with a steering shaft. The first rotor has a slot which is detectable for identifying the steering wheel position. The detector further includes a second rotor which is rotatable interlockingly with the first rotor. A power transmission mechanism is provided to cause the second rotor to rotate intermittently by a predetermined rotation angle, each time the first rotor completes one revolution. The second rotor has a slot for detecting the position of the steering wheel. When the slots of the first and second rotors become aligned, the detector outputs a detection signal indicative of the position of the steering wheel.
