Adjusting device for adjusting components e.g. outer mirror and headlight, of motor car, has piezoelectric element divided into segments in plane that runs perpendicular to direction of actuator, where segments are controlled individually

摘要

The device (10) has components e.g. outer mirror and headlight, adjustable in two directions that are independent of each other, where one of the components is coupled with a transmission mechanism (30) with an adjustment drive. The adjustment drive has a piezoelectric actuator (12) that comprises a disk-shaped piezoelectric element. The piezoelectric element is divided into segments in a plane that runs perpendicular to an effective direction of the actuator, where the segments are arranged at equal angular distances to each other and controlled individually.
