The air spring compressor is a high-voltage air spring compressor which is supplied with electrical energy via the high-voltage on-board electrical system of the motor vehicle. The air spring is supplied with air exclusively and directly via the high-voltage air spring compressor during operation of the motor vehicle.

Abstract: A propulsion device for retracting and extending a wind deflector of a motor vehicle. A first guide rail extends in the longitudinal direction (X) and has a first carriage guide, which extends in the longitudinal direction (X) along the first guide rail and varies in the transverse direction (Y). A second guide rail, which extends parallel to the first guide rail, is spaced apart from the first guide rail in the height direction (Z) and which has a second carriage guide, which extends in the longitudinal direction (X) along the second guide rail and varies in the transverse direction (Y). A pusher element for coupling with the wind deflector, includes a first guide element which can be adjusted in a guided manner in the first carriage guide and a second guide element which can be adjusted in a guided manner in the second carriage guide.

Abstract: A battery cell with an internal cooling element includes an interior in which electrochemically active components are arranged. The interior has an outer wall on each of at least two sides, which are connected to each other by an inner wall. The internal cooling element is arranged in the inner wall. Also described is a battery module with at least two of the battery cells.

Abstract: A charging connection having a charging socket and a charging socket cover, which is arranged in a motor vehicle such that the charging socket cover covers an opening in the vehicle body in a first operating position and the charging socket is arranged in the first operating position behind the charging socket cover. The charging socket cover releases the opening in a second operating position and is arranged behind the opening in a free space of the body. The charging socket is arranged in the second operating position adjacent to the opening, to be available for a charging cable plug to be connected. The charging socket and the charging socket cover are displaceable between the first operating position and the second operating position. The charging socket is electrically connected by way of at least one lever transmission.

Abstract: An electrically or partially electrically driven vehicle has a system (1) for active sound design. Active sound design sounds emitted by one or more loudspeakers (5) are modified depending on the driver type and/or depending on the current driving style. The system (1) has at least one sensor for recording measurement parameters (2) that permit a classification of a current driving style and/or a driver type of a driver of the vehicle. The device (1) has a classification device (3) that is configured to determine the current driving style and/or driver type of the driver of the vehicle based on the measurement parameters (2) recorded by the at least one sensor. The system (1) has a sound control system for controlling and modifying the sounds emitted by the loudspeakers (5) based on the current driving style and/or driver type classified by the classification device (3).

Abstract: Damping arrangement for an axle of an active chassis of a motor vehicle. A damping system interacts with each wheel of the axle. Each of the damping systems includes the following assemblies: a damper including a double-acting hydraulic cylinder and a piston, a hydraulic pump and an electric motor for driving same, and a hydraulic unit which includes a hydraulic reservoir and valves. The hydraulic pump and the hydraulic unit of the respective damping system interact with hydraulic chambers of the hydraulic cylinder in such a manner that a movement of the piston in a first or in a second operating direction can be provided depending on the delivery direction of the hydraulic pump. The electric motors of both damping systems are connected to a common control device and can be actuated thereby, wherein the common control device has electronic assemblies which are distributed on different printed circuit boards.

Abstract: A ducted fan of an aircraft includes a rotor-side fan and a stator-side duct that surrounds the rotor-side fan radially at the outside and defines a flow channel for air flowing via the fan. The stator-side duct has an inner wall that faces toward the rotor-side fan and which is perforated at least in certain sections. The stator-side duct has an outer wall that faces away from the fan. Between the inner wall and the outer wall of the stator-side duct, there are formed cavities which, forming sound-deadening resonators, are coupled via the perforated inner wall to the flow channel for the air flowing via the rotor-side fan. The cavities are filled, in a region which faces away from the inner wall and thus faces toward the outer wall, with activated carbon.

Abstract: An aircraft includes: a body with an arm. The arm carries a lifting rotor. The arm has a cavity. The aircraft may include at least one of: the arm being made of sheet metal, and the cavity includes an embossment or a corrugation in the sheet metal. The cavity may contain cables and the cables run from the body along the arm to the lifting rotor.
