Title:
STEERING ANGLE SENSOR
Document Type and Number:
WIPO Patent Application WO/2013/027506
Kind Code:
A1
Abstract:
Provided is a steering angle sensor which can generate steering wheel rotation angle information with good accuracy by a reduction of the effect of rotation angle errors that occur in a first driven gear and a second driven gear depending on the roundness of a ring-shaped driving gear. A steering angle sensor, which is provided with a ring-shaped driving gear that rotates with the rotation of the steering wheel and a first driven gear and a second driven gear, which are each provided with a magnet and are driven and rotated according to the rotation of the ring-shaped driving gear, the steering angle sensor being for generating steering wheel rotation angle information from magnetic field changes due to the rotation of the first driven gear and the second driven gear. In the steering angle sensor, an intermediate gear, which engages with the ring-shaped driving gear, the first driven gear and the second driven gear, is interposed between the several gears.
