Abstract: An electric motor vehicle traction motor has a motor housing, a liquid-cooled motor stator and a dry running internal motor rotor which is separated fluidically from the motor stator. The motor stator is formed by a stator body with radial stator slots and a plurality of stator coils. The axial phase windings are arranged in the stator slots, and the winding heads of protrude axially out of the stator slots. A slot potted body is made from a potting material and by way of which the stator coil axial phase windings are potted into the stator slots in a fluid-tight manner. The stator coil winding heads are of potting-free configuration and protrude in each case directly into a fluid-tight cooling space. As a result of the omission of a separate split cage, a small air gap is realized and manufacturing costs are reduced.

Abstract: An underbody protection panel including a multi-layered panel structure with a first outer layer, a second outer layer, and at least one intermediate layer arranged between the first outer layer and the second outer layer is provided. The intermediate layer is configured as a compressible intermediate layer, and the mechanical properties of the compressible intermediate layer vary across the surface of the intermediate layer.

Abstract: An air guiding element with a surface element and a longitudinally displaceable carrier element. The surface element is articulated to the carrier element in a movably mounted manner, furthermore with a drive element with a gearwheel. The carrier element can be driven in a longitudinally displaceable manner by the gearwheel transmission in such a way that a rack of the gearwheel transmission is connected to the drive element in a drivable manner via a spur gear and the rack is in driving connection with the carrier element.

Abstract: A charging or tank door assembly of a motor vehicle, including a base body receiving a charging socket or a tank inlet, a door body pivotable about an axis of rotation and supporting a panel body on a first position, and a push-push mechanism for locking the door body and releasing the door body in the first position. In the first position, the door body closes an opening in a body of the motor vehicle and blocks access to the charging socket or to the tank inlet. In a second position, the door body releases the opening of the body of the motor vehicle and the access to the charging socket or to the tank inlet. Relative to the first position, the push-push mechanism is arranged on a different side of the axis of rotation than the first portion, supporting the panel body, of the door body.

Abstract: A lift unit for an aircraft, having the following features: a fan, an engine bearing axially offset from the fan, and a cylindrical electric engine having a sheath surface framed by the engine bearing.

Abstract: A motor vehicle with an automatically settable front wing and an automatically settable rear wing, each of which is settable under the control of an actuator. Owing to the incident flow of air at the front axle, a downforce at the front axle (FDF) can be set by positioning the front wing. Owing to the incident flow of air at the rear axle, a downforce at the rear axle (RDF) can be set by positioning the rear wing. A resultant downforce (DF) acting through a point (CoP) can be generated and an aero balance (AB) can be set. The rear wing and/or the front wing can be set automatically in dependence on an operating state of the motor vehicle such that a predetermined downforce (FDF) at the front axle, a predetermined downforce (RDF) at the rear axle, a predetermined resultant downforce (DF) and/or a predetermined aero balance (AB) is obtained.

Abstract: Wheel carrier apparatus for a motor vehicle including a wheel hub to which a vehicle wheel can be fastened, and an articulation apparatus for torque transmission having an articulation housing and an articulation drive element operatively connected to the articulation housing. The articulation housing is arranged coaxially to the wheel hub and is connected to the wheel hub in a rotationally fixed manner. The wheel carrier apparatus further includes a wheel carrier on which the wheel hub and the articulation housing are borne via a wheel bearing in a rotationally fixed manner. The wheel bearing includes an outer bearing ring fastened to the wheel carrier, an inner bearing ring divided in the axial direction, and multiple rolling bodies arranged radially between the inner bearing ring and the outer bearing ring. The divided inner bearing ring includes a first inner bearing ring element and a second inner bearing ring element.

Abstract: A rollover device for a passenger compartment of a motor vehicle includes a plurality of struts made of fiber-reinforced plastic, and a plurality of fastening feet made of metallic material for connecting the rollover device to a vehicle body. At least one fastening foot made of metallic material is connected to a respective strut made of fiber-reinforced plastic via a material-locking connection on the one hand and via a form-locking connection on the other hand.

Abstract: A method for arranging a generalized multilevel converter switching topology with switched capacitors for converting DC current into AC current, wherein the arrangement can be configured with regard to predetermined output voltage levels. With the same number of semiconductor switches, a higher number of voltage levels can be achieved in comparison to previous methods. Depending on the given problem, a maximum output voltage of the AC current may vary from significantly lower values than the input voltage of the DC current up to a multiple of these values. The generalized circuit topology may be adapted to a desired number of voltage levels by a repeatable arrangement of voltage level units that can be arranged in a row and to a multiphase load by a corresponding selection of a number of sub-modules. Furthermore, a modular multilevel converter configured with the circuit topology is described.

Abstract: A multi-chamber air spring includes a main volume, an additional volume and a switching valve. The switching valve is designed to connect the additional volume to the main volume in a first operating state of the multi-chamber air spring, and to disconnect the additional volume from the main volume in a second operating state of the multi-chamber air spring. The switching valve is designed to open in the second operating state from a first predetermined limit pressure difference between the additional volume and the main volume.
