Actuator for motor vehicle applications

Abstract

The invention relates to an actuator for motor vehicle applications, in particular for a motor vehicle lock and preferably an actuator integrated in a motor vehicle door lock. In its basic construction, the actuator has an electric motor (4) and an actuating element (10) which is acted upon directly or indirectly by the electric motor (4) via a drive train (5 to 9). The drive train (5 to 9) is equipped with at least one first evoloid toothing (5, 6) and one second evoloid toothing (7, 8) which adjoin one another. Each evoloid toothing (5, 6; 7, 8) has: an evoloid pinion (5, 7) which can be rotated about an evoloid axle (5a, 7a); and an evoloid output wheel (6, 8) which meshes with the evoloid pinion and can be rotated in each case about a wheel axle (6a, 8a). According to the invention, the two evoloid toothings (5, 6; 7, 8) are positioned perpendicular relative to one another in such a way that the two evoloid axles (5a, 7a) are for the most part perpendicular relative to one another.
