Abstract
The disclosure relates to a locking unit, in particular for the parking lock of an automatic transmission. The locking unit has a solenoid and at least one latching element. The latching element interacts with the armature or the armature rod of the solenoid, and the piston has at least one latching receptacle. The piston is securable by the retaining interaction of the latching element with the latching receptacle. Here, the piston is at least partially mounted in a housing, and the locking unit has an internal tube section, which is connected to the housing in a fluid-tight manner. The disclosure furthermore relates to a method for producing such a locking unit.
