Headlamp adjusting system for motor vehicle - uses transducer connected to suspension system to automatically adjust attitude of headlight reflector via geared motor drive

摘要

The electromotive adjusting device for headlamps of motor vehicles infinitely controls or regulates the light range of the dipped beam in conformity with variations in the deflection of the spring suspension of the body. The device has a two-part dust-proof housing (34,56) which contains an electric motor having a reduction gear, an output gear wheel (30) of which moves a push rod by virtue of screw threads (32,33) and a connecting member (14) transmits the stroke of the push rod to the reflector. A printed circuit board (50) having round plug pins carries an induction coil (45) of an actual value transducer whose plunger (46) is disposed on the worm wheel (30).
