Abstract: In a parking lock for an automatic transmission, an electrical parking lock actuator has an electric motor, a spur gear stage driveable by the electric motor, and a worm gear stage driveable by the spur gear stage. A worm shaft of the worm gear stage is connected rotationally conjointly to an output gear of the spur gear stage, and a worm gear of the worm gear stage is connected rotationally conjointly to a transmission-side parking lock shaft. The worm shaft is fixed in an axially displaceable manner in the output gear. A stop limits the pivoting movement of the worm gear when a parking lock position of the parking lock shaft is reached. A spring braces the worm shaft in an axial direction of the worm shaft against a holding mechanism which is situated in a stop position, in which the holding mechanism is fixed by an electrically energized electromagnet.

The charging plug includes power contacts, a signal contact, a rectifier, and a control and protection device. The power contacts and signal contact electrically connect the charging plug to the vehicle. The rectifier is connected to the feed line and to the power contacts for converting an alternating current obtained by the feed line into a direct current that is delivered by the power contacts to the vehicle in a charging process. The control and protection device is connected to the feed line, to the power contacts and to the signal contact for matching the charging process to the vehicle by means of the signal contact.

Abstract: A charging socket cover for an electrically operated motor vehicle having a closing apparatus, a pivoting apparatus and a drive apparatus. The pivoting apparatus is driven by way of the drive apparatus in order to pivot the closing apparatus between a closed position, in which the closing apparatus closes an opening which is made in a vehicle body part of the motor vehicle, and an open position, in which the closing apparatus releases the opening and is arranged substantially behind the vehicle body part. The pivoting apparatus and the drive apparatus are configured to pivot the closing apparatus by way of a rotational movement about a rotational axis and by way of a translational movement parallel to the rotational axis between the closed position and the open position and/or between the open position and the closed position.

A gap extends at an axial extension between a first component and a second component so that the components are disposed along both sides of the gap relative to each other without coming into contact. An annular first body is mounted on the first component, which is disposed without contact in relation to the second component group. The second component includes a section, which is separated by a radial gap and is located radially outside and across from a region of the first body that extends in the axial direction, and the first body is situated radially outside and circumferentially about the axis in relation to the bearing elements. The first body is able to hold lubricant. Alternatively or additionally, a corresponding annular second body is fixed in place on the second component.
