Abstract
A parking lock device of a gearbox is provided. The device includes a gearbox shaft, a gearbox housing, a locking ring which may be displaced axially along the gearbox shaft, a control ring which may be moved axially relative to the locking ring and the gearbox shaft. A movement of the control ring relative to the locking ring axially along the gearbox shaft causes an axial movement of the locking ring axially along the gearbox shaft, and the control ring displaces the locking ring in an activated state axially along the gearbox shaft to a predetermined axial position along the gearbox shaft. The gearbox shaft, the gearbox housing and the locking ring are designed and adapted to one another in such a way that in an activated state of the locking ring there is a positive engagement between the gearbox shaft, the gearbox housing and the locking ring.
