In particular, the reluctance motor device is provided in at least one operating state, preferably when the vehicle is cornering, to drive two front wheels or two rear wheels via the two driven elements, each with a different power. The two output elements are preferably arranged individually at a distance from one another. The axis of rotation of the rotor unit preferably includes the axes of rotation of the driven elements. In particular, the axes of rotation of the output elements are arranged coaxially with one another.

In particular, the reluctance motor device is at least at least arranged essentially between the two wheels. The rotor unit is preferably provided to transmit the rotational movement generated by the reluctance force at least partially to the output elements.

An advantageous direct drive of the wheels of the vehicle can be achieved by the design of the reluctance motor device according to the invention. An advantageously compact configuration can be achieved. This can be made possible before geous low space requirements in the vehicle. Advantageously, high efficiency can be made possible when driving the wheels, in particular since intermediate components, such as a transmission or the like, can be at least partially omitted.

Furthermore, it is proposed that the reluctance motor device comprises at least one force distribution unit, which is intended to control and/or regulate a distribution of a drive force generated by the at least one rotary movement between the output elements. It can be made possible before geous high efficiency when driving the wheels, especially since, for example, friction losses when cornering of the vehicle can be reduced. An advantageous need-optimized drive of the wheels can be realized. The force distribution unit is preferably designed electrically and/or electronically or mechanically. A "force distribution unit" is to be understood in particular as a structural unit of a machine, in particular the reluctance motor device and/or the reluctance motor, which is intended to transmit a force, in particular the driving force, transmitted by at least one component of the machine, in particular the rotor unit. to distribute to more than one component, in particular the two driven elements. The force distribution unit is preferably provided to distribute the drive force generated by the at least one rotary movement between the output elements by setting at least one drive parameter of the at least one stator unit or the at least one rotor unit or by means of a mechanical limitation of the drive force to be transmitted to an output element, to control and/or regulate, in particular via a differential gear. The force distribution unit is particularly preferably provided for the purpose of individually, in particular depending on the driving situation, to be distributed between the two output elements. The force distribution unit is preferably arranged on the rotor unit and/or the stator unit or is at least electrically and/or mechanically connected to the rotor unit and/or the stator unit.

In addition, it is proposed that the power distribution unit is designed as a differential gear which is at least partially designed in one piece with the rotor unit. An advantageously compact design can be made possible, in particular since the force distribution unit can be designed as part of the reluctance motor. A direct drive of the two wheels via a single reluctance motor can be made possible. An advantageously low number of different components can be made possible. As a result, advantageously low production and/or maintenance costs can be achieved. The force distribution unit is preferably at least partially designed in one piece with the rotor body. In particular, the force distribution unit is formed at least partially in one piece with the output elements. The force distribution unit is preferably provided for the purpose of mechanically transferring a driving force from the rotor body to the output elements. In particular, the power distribution unit is provided to allow rotation of the driven elements about the axes of rotation of the driven elements, each with a different rotational speed.

It is also proposed that the force distribution unit is at least partially arranged on the axis of rotation of the rotor unit and, viewed along the axis of rotation of the rotor unit, is at least essentially completely surrounded by at least one, in particular the aforementioned, rotor body of the rotor unit and/or by the stator unit . Advantageously, complete integration of the force distribution unit can be made possible. It can be achieved before geous compact design for a differential drive of the two wheels. The fact that “the force distribution unit is at least partially arranged on the axis of rotation of the rotor unit” should be understood in particular to mean that the force distribution unit comprises at least one component through which the axis of rotation runs and/or which intersects the axis of rotation. Under "substantially completely enclosed" should be understood in particular that a structural unit, in particular the force distribution unit, in at least one direction, in particular a direction running along the axis of rotation, viewed from at least one point of the structural unit over an angular range of at least 324°, preferably at least 342° and preferably at least 353°, from at least one other structural unit or a structural part, in particular the rotor body and/or the stator unit.

An advantageously small number of different components can be made possible. As a result, advantageously low manufacturing and/or maintenance costs can be achieved. An advantageously compact configuration can be achieved, in particular since the force distribution unit can be arranged directly on an inner region of the rotor body. The central axis of the at least one bevel gear preferably intersects the axis of rotation of the rotor unit. The central axis of the at least one bevel gear is preferably arranged at least essentially perpendicularly to the axis of rotation of the rotor unit. In particular in the case of an embodiment of the force distribution unit with at least two bevel gears, the bevel gears are preferably arranged at least substantially evenly distributed around the axis of rotation. “Essentially evenly distributed” is to be understood in particular as meaning an arrangement of components, in particular the bevel gears, with the components being arranged on a surface or a path, in particular a circumferential path around the axis of rotation, such that a distance between one of the components to a closest component of the components on the area or the route is at least essentially the same for all components. Especially at In one configuration of the force distribution unit with at least two bevel gears, the bevel gears are arranged on the rotor body at an angular distance about the axis of rotation of at least essentially 180° to one another, viewed along the axis of rotation. In particular, the bevel gear, in particular the two bevel gears, each have a maximum extension parallel to the axis of rotation, which is in particular greater than a maximum extension of the rotor body aligned parallel to the axis of rotation. In particular, the bevel gear, in particular the two bevel gears, extends at least partially into the recess of the stator body and/or the further stator body.

In addition, it is proposed that the power distribution unit comprises at least two additional bevel gears, which are each arranged in a torque-proof manner on one of the output elements, the center axis of the at least one bevel gear being at least substantially perpendicular to the center axes of the two other bevel gears, to the axis of rotation of the rotor unit and/or or is arranged selemente to the axes of rotation of the output. An advantageously small number of different components can be made possible, in particular since the driven elements can be formed in one piece with the other bevel gears. As a result, advantageously low manufacturing and/or maintenance costs can be achieved. "Rotatably fixed" is to be understood in particular as meaning that a component, in particular one of the other bevel gears, is arranged on another component, in particular one of the two output elements, in such a way that rotation of the component relative to the other component is prevented, for example by a form - and/or non-positive connection is prevented. It is conceivable that in each case one of the two further bevel gears is designed in one piece with one of the two driven elements. Alternatively or additionally, it is conceivable that one of the two further bevel gears is plugged onto one of the two output elements and is arranged on the output element in a rotationally fixed manner, for example via a form fit. Preferably, the axes of rotation of the output elements include the center axes of the two other bevel gears. In particular, the central axes of the two other bevel gears are arranged coaxially with one another. The center axis of the at least one bevel gear preferably intersects the axes of rotation of the output elements and/or the center axes of the two other bevel gears. Preferably, the two further bevel gears each have a maximum circumference that is smaller than a maximum circumference of the bevel gear, especially the two bevel gears. The further bevel gears and the bevel gear, in particular the bevel gears, are preferably designed to correspond to one another. Preferably, the other bevel gears and the bevel gear, in particular the special bevel gears, each have a helical gearing. Particularly before the further bevel gears and the bevel gear, in particular the bevel gears, are intended to engage with one another, with torque being transmitted to the further bevel gears in particular during the rotary movement of the bevel gear, in particular the two bevel gears, about the axis of rotation. The rotor body with the bevel gear(s) preferably acts as a sun gear of a differential gear.

It is also proposed that the force distribution unit, in particular viewed perpendicularly to the axis of rotation of the rotor unit, is arranged at least essentially completely within a maximum longitudinal extension of the stator unit that is at least essentially parallel to the axis of rotation of the rotor unit. An advantageously compact configuration can be achieved.

Advantageously, direct transmission of the driving force to the driven elements can be made possible. The force distribution unit preferably has a maximum longitudinal extension that is aligned at least essentially parallel to the axis of rotation of the rotor unit. The fact that “the force distribution unit is arranged at least essentially completely within a maximum longitudinal extension of the stator unit that is at least essentially parallel to the axis of rotation of the rotor unit” is to be understood in particular as meaning that at least 90%, preferably at least 95% and preferably at least 98%, the maximum longitudinal extent of the force distribution unit, in particular viewed perpendicularly to the axis of rotation of the rotor unit, are arranged within the maximum longitudinal extent of the stator unit. The maximum longitudinal extent of the force distribution unit, in particular viewed perpendicularly to the axis of rotation of the rotor unit, is particularly preferably arranged completely within the maximum longitudinal extent of the stator unit. The maximum longitudinal extent of the stator unit preferably extends along the central axes of the stator body. The maximum longitudinal extent of the stator unit preferably extends from an outside of the at least one stator body facing away from the rotor unit to an outside of the at least one further stator body facing away from the rotor unit, with in particular the Outsides of the stator body and the further stator body are arranged at least obliquely, in particular at least substantially perpendicularly, to the axis of rotation and/or to the central axes of the stator body and/or the further stator body.
