ABSTRACT:
The present invention relates to a steering angle sensor, which includes a substrate. A shaft bore and a first gear are adapted on the substrate. The first gear has a shaft sleeve, which passes through the shaft bore. And a steering column of a steering wheel passes through the shaft sleeve. A second gear is adapted on the substrate, and is in mesh with the first gear. A rotary sensor is located atop and assembled with the second gear. Besides, a signal processing circuit is coupled electrically with the rotary sensor. By simply meshing the first and the second gears and passing the steering column of the steering wheel through the first gear, when the steering wheel turns, the second gear will be driven to turn as well, which, in turn, drives the rotary sensor. Thereby, the number of components in the steering angle sensor is reduced, and the volume thereof is reduced effectively as well.
