Abstract: Damping arrangement of an active chassis for an axle of a vehicle. A damping system cooperates with each wheel. Each of the damping systems has a damper having a double-acting hydraulic cylinder and a piston, a reversible hydraulic pump and an electric motor, and a hydraulic unit having a hydraulic reservoir and valves. The hydraulic pump and the hydraulic unit of the respective damping system cooperate with the hydraulic cylinder thereof such that, dependent upon the conveying direction of the hydraulic pump, a movement of the piston in a first actuation direction or in a second actuation direction can be provided. The electric motors of both damping systems are connected to and drivable by a common control device. A position sensor is associated with each electric motor to acquire the rotor position of the respective electric motor. A pressure sensor is associated with each hydraulic pump to acquire a pressure.

Abstract: A rear portion of a body of a motor vehicle includes a shell, which at least partially delimits the rear portion from an environment with the aid of a panel element. For absorbing compressive forces (DK) and tensile forces (ZK) acting on the rear portion, the rear portion includes a first support element and a second support element, wherein the first support element is designed to absorb the compressive forces (DK) and the second support element is designed to absorb the tensile forces (ZK).

Abstract: A cargo floor, in particular a trunk or storage floor, for a motor vehicle. The cargo floor includes a layer-shaped construction with a core layer, a first reinforcement layer and a second reinforcement layer. The core layer is arranged between the first reinforcement layer and the second reinforcement layer and includes a honeycomb structure produced in particular from polypropylene (PP). It is conceivable that the first reinforcement layer and/or the second reinforcement layer each include a meshwork made of a plurality of thermoplastic continuous fiber tapes (UD tapes).

Abstract: An air guide device for a motor vehicle having an air guide element and a movement mechanism. The air guide element forming a rear side part of a body of the motor vehicle so as to be movable relative to the remaining body. The air guide element is movable between an inoperative position and at least one operating end position. The air guide element, in its inoperative position, is flush with the remaining body. The rear side part has a flow guide surface which faces an environment of the motor vehicle and along which air flows. The air guide element has a surface which is at least part of the flow guide surface. The air guide element, in its operating end position, is configured to extend the flow guide surface along a body longitudinal axis (X) of the body.

Abstract: A drive unit for an electric vehicle, including an electric machine, a gear mechanism, a housing, wherein the electric machine and the gear mechanism are arranged in an interior of the housing, and a receiving apparatus for a pulse inverter module, wherein the housing has an opening and the receiving apparatus is arranged in the interior of the housing directly behind the opening.

Abstract: An electrical apparatus, including a first housing having a fluid-filled or fluid-perfused wet space and a dry space that are separated from one another by a wall, wherein the wall includes an opening, one or more power-conducting and/or power-switching elements arranged in the wet space, and a control electronics for the one or more power-switching elements arranged in the dry space.
