Abstract: A commercial vehicle, such as an electric bus, comprising at least one electrically driven axle having a transmission-motor unit associated with at least one wheel assembly. A motor of the transmission-motor unit comprises a stator and a rotor. The rotor is connected in a torque-transmitting manner to a respective wheel assembly via a transmission. The rotor has an overhung bearing, and the rotor is mounted by the bearing of the transmission.

Abstract: A drive apparatus for a closure element of a motor vehicle, including a tube defining an axis, a spindle disposed within the tube and configured to translate along the axis from an extended position to a first retracted position and a second retracted position, a spindle nut disposed within the tube and operatively engaged to the spindle, a stop nut fixed to the spindle, and a damping element disposed between the spindle nut and the stop nut. The tube defines a first end stop face and the stop nut defines a second end stop face, and when the spindle is in the first retracted position, the damping element engages the first end stop face and is spaced apart from the stop nut.

Abstract: An electrical axial flux machine including a rotor shaft is provided. The rotor shaft is rotatable about an axis of rotation. Two rotors are arranged on the rotor shaft. The two rotors are spaced apart when viewed in a direction of the axis of rotation. The axial flux machine further includes a stator arranged between the two rotors when viewed in the direction of the axis of rotation. The stator includes stator teeth. Each of the stator tooth extends in the direction of the axis of rotation between two end regions. The stator teeth are arranged and distributed uniformly around the axis of rotation at a radial spacing from the axis of rotation and include a stator winding system. At least one ring structure is provided connecting the two end regions of the stator teeth. A housing further surrounds the stator radially on the outside.

Abstract: An electrically driven aircraft includes at least one drive arrangement which has an aircraft propeller comprising a propeller shaft, a propeller bearing configured to radially and axially support the propeller shaft, a propeller hub which is driven by the propeller shaft, and a plurality of propeller blades attached to the propeller hub. A dynamoelectric rotary machine has a stator and a rotor which interacts with the stator and is coupled directly to the propeller shaft. The propeller bearing and the stator, are accommodated in a support structure which is mechanically coupled to an aircraft structure of the aircraft.

Abstract: A synchronous machine has a rotor rotatable about an axis of rotation and a stator surrounding the rotor radially on the outside. When viewed in axial direction, the rotor has a number of rotor rings running tangentially around the axis of rotation. When viewed in tangential direction about the axis of rotation, the rotor rings each have a plurality of claws of soft-magnetic material. The claws are in the form of an L, defined by first and second limbs. An excitation device is fixed to the stator and has, for each rotor ring, a magnetic field generator which interacts with the respective rotor ring and is arranged radially inside the respective rotor ring. The magnetic field generator generates a magnetic field directed in the axial direction and is coupled magnetically to the second limb of the claws of the respective rotor ring in the region of the radially inner termination.
