Swash-plate-type gearing for adjustment devices

A wobble mechanism for adjusting devices comprises:

• a housing,
• an outer part, having an internal toothing, which is concentric with a joint axis,
• an inner part, having an external toothing, which is concentric with an eccentric axis, which runs offset in parallel by an off-center distance to the joint axis,
• an engagement region, in which the external toothing engages with the internal toothing and which is located on a straight line, which in each case intersects the joint axis and the eccentric axis at a right angle, wherein on this straight line the eccentric axis lies between the joint axis and the engagement region, and
• a free space located 180° opposite the engagement region and is likewise located on the straight line and in which the external toothing is disengaged and at a distance from the internal toothing,
• wherein a locking part is provided, said locked part having a locking region, which is located in the free space,
• wherein the inner part has a circular recess that is concentric with the eccentric axis and which is limited by a sliding surface, that the wobble mechanism further has a wobble pin that abuts on the sliding surface and is rotatably received in the recess, and that the rotational movement of the locking part is synchronized with the rotational movement of the wobble pin, wherein said wobble mechanism has a drive wheel, which is concentric with the joint axis and which is connected to the wobble pin, and that the locking part is arranged on the drive wheel and rotates with the drive wheel.
