The present disclosure describes a parking lock gear mechanism including a planetary gear train with a sun gear, a ring gear, and at least one planet gear that meshes with the sun gear and the ring gear. The at least one planet gear may be attached to a rotating planet carrier. The parking lock gear mechanism may also have a spring unit coupled to the ring gear, where the spring unit is configured such that it is tensioned by a rotation of the ring gear, and exerts a torque and/or force on the ring gear when it is tensioned. A ring gear securing unit may be configured to secure the ring gear against rotation in a first operating state, and to release the ring gear such that it can rotate in a second operating state.

Parking lock gear mechanism, and method for operating a parking lock gear mechanism of a vehicle

An electromagnetic control device has a coil with a central axis and an interior space, and a control element that moves along the axis and is arranged at least partially within an interior space of the coil. The control element comprises an armature that axially moves to a desired position when the coil is energized. The coil is divided into at least two separate portions that are arranged axially behind one another and connected electrically in series with one another. An electric central tap is provided, between two adjacent coil portions, by which a sensor current, provided for determining an axial position of the armature, can be fed into a subset of the coil portions. When the armature is in a defined axial position, an axial end face of the armature is located within an axial area determined by an axial separation zone provided between two adjacent coil portions.

Electromagnetic actuating device with ability for position detection of an armature

A device for the mechanical fastening and electrical contact with at least one control element (), having first electrical contacts (), within a housing (). Mating second electrical contacts () are arranged on a connecting element () which can also be plugged into the housing (). During assembly, the at least one control element () and the connecting element () are both plugged into the housing () so that such plugging engagement achieves electrical connection between the first electrical contacts () and the second electrical contacts () and, at the same time, an interlocked fastening of the at least one control element () with the housing ().
