STEERING WHEEL ANGLE SENSING UNIT FOR A VEHICLE

摘要

PURPOSE: A steering wheel angle sensor part is provided to reduce hysteresis and an error band by removing or minimizing error generating factors. CONSTITUTION: A steering wheel angle sensor part(10) comprises a housing part(100), a printed circuit board(200), a gear part(300), a sensor part(500), and a gear holder part(400). The printed circuit board is arranged in the housing part. The gear comprises a main gear(310) which is arranged in the housing part by passing through the housing part and the printed circuit board and a sub gear(320) which is meshed with the main gear and rotated together. The sensor part comprises a magnetic sensor(510) and a magnet(520). The gear holder part is movably installed in the housing part and elastically supports the sub gear.
