  • the invention relates to a wheel drive unit for a wheel of an electrically driven vehicle, with an electric see machine for driving the wheel, which has a stator and a stator rotatably mounted on the rotor, which is connected to the wheel of the vehicle, and with an electronic control device for driving the electric machine.

  • an electrically driven vehicle namely preferably an electrically driven motor vehicle, d. H. an electric vehicle.
  • wheel drive units separately for the wheels of the motor vehicle in such an electric vehicle, which can be embodied as wheel-near drive units or else as wheel hub motors. Both variants of the wheel drive unit serve to drive a single wheel.
  • wheel drive unit can be provided for each wheel of the motor vehicle; alternatively, however, only two wheels of the motor vehicle can be equipped with one wheel drive unit, namely either the rear wheels or the front wheels.
  • a solution according to the wheel drive unit for a wheel of an electrically driven vehicle includes an electric Machine for driving the wheel, which has a stator and a rotor rotatably mounted on the stator, which is connectable to the wheel of the vehicle.
  • the wheel drive unit also includes an electronic control device for controlling the electric machine.
  • the wheel drive unit additionally has an eddy current brake, by means of which the rotor and thus also the wheel can be braked.
  • the effect according to the invention is thus achieved by integrating an eddy current brake into the wheel drive unit, by means of which the rotor of the electric machine and thereby also the wheel of the vehicle can be magnetically braked.
  • an eddy current brake With such an eddy current brake, it is possible to generate particularly high deceleration torques, without having to use an additional, mechanical disk brake or the like.
  • An eddy current brake is also a wear-free brake in which the eddy current losses are used for braking the rotor. For this purpose, only one - in particular inhomogeneous - magnetic field must be generated, due to which eddy currents are induced in the rotor or an additional disk connected to the rotor.
  • Another advantage of the wheel drive unit according to the invention is that the control of the entire braking operation of the vehicle can also be done via the electronic control device of the electric machine, so that the external or from a vehicle side Control unit transmitted braking torque default internally in the wheel drive unit either via the electromotive braking or via the eddy current brake can be implemented.
  • the eddy current brake can only be activated when the braking torques during electromotive braking are no longer sufficient to implement the external braking torque specification. It can even be provided that the electromotive braking can take place parallel to time and thus simultaneously with the braking by means of the eddy current brake.
  • the existing power electronics need only be slightly modified.
  • the eddy current brake has a disc formed of a metallic material, which is rotatably connected to the rotor and in which eddy currents are generated for braking the rotor.
  • a disk With such a disk, it is possible to generate the eddy currents on a relatively large area and thus also to provide relatively large braking torques.
  • Such a disk may extend in the radial direction perpendicular to a rotational axis of the rotor. It can be arranged and fixed on a shaft of the rotor and, in particular, can be of circular design. The arrangement of the disc perpendicular to the axis of rotation of the rotor ensures that this disc is axially accessible both from one side and from the other axial side for magnetic fields, which in turn is very favorable for the arrangement of electromagnets.
  • the eddy current brake preferably has at least one electromagnet, which is designed to generate a magnetic braking force.
  • electromagnet two different embodiments can now be provided:
  • the at least one electric magnet is a magnet of the stator of the electric machine, which is also designed to drive the rotor.
  • a magnet which is present anyway in the case of the electric machine is also used for the function of the eddy current brake, so that the use of an additional electromagnet is unnecessary.
  • the at least one electromagnet of the eddy current brake is a magnet which is separate from the electromagnet of the stator.
  • This embodiment has the advantage that the electromagnet can advantageously be placed at a small distance from said disk and the arrangement of the electromagnet is thus not limited to the drive-specific arrangement of the stator. Thus, even greater braking torques or braking forces can be generated with the eddy current brake.
  • the electromagnet may in this embodiment be arranged so that the magnetic flux generated by means of this electromagnet is perpendicular to the said disc.
  • the electromagnet can thus have two core legs, which can be arranged on the opposite sides of the disk and can both point in the axial direction of the disk, so that the electromagnet engages around the disk virtually on both sides.
  • the control device of the electrical machine is also designed to control the eddy current brake.
  • the same electronic control device - such as a microcontroller - both the electric machine and the eddy current brake can be controlled.
  • the internal control device of the wheel drive unit thus assumes two different functions, namely on the one hand the function of driving the electric machine and on the other hand, the function of driving the eddy current brake.
  • the microcontroller which can be used as a control device, thus several components can be controlled.
  • the eddy current brake is supplied or controlled via one and the same power electronics, via which the electrical Machine is supplied with electrical energy.
  • an electrical DC link can be provided, in which an electrical DC link voltage is provided to a DC link capacitor. This voltage can then serve both to supply the eddy current brake and to supply the electric machine.
  • the common power electronics include an inverter, which can provide an alternating voltage for the electrical machine from the intermediate circuit voltage. This inverter can also be used to generate an electrical AC voltage for the eddy current brake. The number of components used is thus reduced to a minimum.
  • the control device may have an interface for communication with an on-board vehicle control device.
  • the control device may then be designed to receive both drive control commands relating to the driving of the wheel and brake control commands with respect to the control of the eddy-current brake via this interface. Consequently, an already existing interface can be used in order to be able to transmit control commands relating to the control of the eddy-current brake to the control device.
  • the control device thus does not need to be reconfigured in a complex manner, but it can be used already existing control devices.
  • the electric machine is preferably a permanent magnet-excited synchronous machine.
  • the rotor can carry permanent magnets, while the stator can have a stator winding with, in particular, three phase phases.

  • the wheel is braked exclusively by means of the wheel drive unit, and in particular exclusively by means of the eddy current brake and / or electric motor. It is therefore unnecessary to use a mechanical brake with the associated disadvantages in terms of wear, space and cost.
