    The invention relates to a drive unit for upgrading or retrofitting a bicycle, preferably a bicycle, with an electric motor, which is designed as a disk motor, with a rotor disk including permanent magnets and an annular stator with windings, which generate an alternating electric field for driving the rotor disk.
    Bicycles with auxiliary drive or bicycles that can be equipped with a drive unit or retrofitted, are already long state of the art. The same applies to other motorized two-wheelers, such as scooters, e-bikes or e-scooters that can be equipped with an electric motor. In the case of bicycles, a distinction is made above all between bicycles with limited pedal assistance and bicycles with pedal-independent additional drive.
    From DE 101 27 769 Al, for example, a bicycle with an electric auxiliary drive is known, in which the output shaft of the electric motor via a planetary gear with the hub of the rear wheel of the bicycle is coupled. The planetary gear comprises three switching stages. The electric motor is designed as a hollow shaft motor and arranged with its central axis coaxial with the central axis of the rear wheel.
    From DE 10 2010 026 405 Al a bicycle with an electric auxiliary drive is known. The auxiliary drive comprises an electric motor mounted on the frame, the output shaft of which extends in the bicycle longitudinal direction and is drive-connected to the rear wheel via an angular gear. The auxiliary drive is offered as a retrofit kit to equip a conventional bicycle with an electric drive. The electric motor is preferably designed as a tubular motor and can be attached with a clamp on the chainstay of the rear wheel.
    Finally, from DE 10 2012 205 361 Al a brushless electric machine in the form of a disc motor is known, wherein permanent magnets are arranged in the rotor of the motor, which form magnetic poles in the pole pieces of the rotor. The rotor is driven by an alternating field, which is generated in the windings, which are arranged on the annular stator.
    The object of the invention is based on the above-described prior art, a drive unit for a bicycle, preferably for a bicycle, educate in such a way that a simple equipment or retrofitting of the bicycle with the drive unit can be performed.
    This object is achieved in that the rotor disk rotatably connected to a receptacle on the front or rear wheel of the bicycle is connectable and that the annular stator is detachably fastened to a frame part of the bicycle can be fastened.
    It when the installation of the drive unit already existing structures of the bicycle for the attachment of the individual components of the drive unit can be used is particularly advantageous. Thus, according to the invention, the rotor disk rotationally fixed to the existing receptacle for a brake disc on the wheel hub of the front or rear wheel of the bicycle fixed. All you have to do is remove the respective wheel, remove any brake disc and attach the rotor disc of the disc motor to the perforated rim of the brake disc.
    Furthermore, the drive unit according to the invention fastening means, preferably an adapter, an adjustment plate and a guide element with which the annular stator is attached to the existing receptacle for a caliper on the front fork or the rear fork (or the rear strut).
    It is particularly advantageous if the annular stator is designed to be hinged in the circumferential direction and removable from the rotor disk, wherein the annular stator has a manually operable fixing device with which the stator can be fixed without tools in its operating position.
    Electric bicycles or bicycles with auxiliary drive are unfortunately often endangered by theft and vandalism. With the present invention, it is now possible for the first time to remove essential parts of the drive unit, namely the annular stator, in a few steps and without the use of tools from the bicycle and to keep safe.
    According to a further advantageous embodiment variant, a rechargeable energy store, preferably a lithium-ion battery, is arranged on the outer circumference of the annular stator, preferably in the region of the hinged sections, which is removed from the rotor together with the annular stator and charged, for example in FIG the apartment or workplace, can be taken.
    The invention will be explained in more detail below with reference to the illustrated embodiments. Show it:

    2 shows the disk motor according to FIG. 1 in a three-dimensional representation, FIG.
    3 shows a mounting location for the disc motor according to the invention on the front fork of a bicycle,
    4 shows the individual parts of the drive unit according to the invention in an exploded view,
    5 shows a variant of the disc motor according to FIG. 1 with a rechargeable energy store, FIG.
    6 is a detailed view of a locking device of the hinged stator,
    Fig. 7 shows the disc motor of the drive unit according to the invention according to FIG. 5 in a mounting situation on the front wheel of a bicycle, as well
    8 shows a bicycle with the drive unit according to the invention on the front wheel and on the rear wheel.
    The illustrated in FIGS. 1 to 4, the first variant of a drive unit for upgrading or retrofitting a two-wheeler consists essentially of the disc motor 10 and various adapter and fastening means, which are shown in more detail in Fig. 4.
    The disk motor 10 has a rotor disk 11 with permanent magnets 12 which, while forming an air gap, are surrounded by a substantially annular stator 13 together with windings which conventionally generate an alternating electrical field for driving the rotor disk 11.
    Since many bicycles are already offered with brake discs, for example, at the hub of the front wheel (see FIG. 3) a receptacle 6 is provided for the brake disc, the perforated ring 8 is suitable for the attachment of the rotor disc 11 of the disc motor 10. When retrofitting thus only the front wheel removed and the brake disc must be removed, after which the rotor disk 11 can be fixed with the screws provided for the brake disc on the perforated ring 8. The brake function can be at least partially replaced by the disc motor 10, which also acts as an engine brake, and, if necessary, by a rim brake.
    As shown in detail in Fig. 4, the drive unit fastening means, such as an adapter 14, an adjustment plate 15 and a guide member 20, with which the annular stator 13 can be fixed to the receptacle 7 for a brake caliper on the front fork 4. When recording 7 for the caliper, a uniform dimension has prevailed, which is known for example under the standard IS2000. Such a receptacle 7 for the caliper is also located on the rear fork or the rear strut 5 (see Fig. 8), so that the attachment of the disc motor 10 is also possible at this position without alterations.
    In order to remove the annular stator 13 in the plane of the disc motor 10 of the fixed rotor disc 11 without removing the front wheel, the stator 13 is designed to be hinged in the circumferential direction, wherein a manually operable fixing device is provided in the form of a handwheel 16, which in the Mounting the adjustment plate 15 passes through from the outside and presses the attached to the stator 13 guide member 20 to the adjustment plate 15.
    The annular stator 13 is shown in Fig. 4 in its unfolded position, and shows a base portion 17, on which a housing 18 is formed for receiving a motor control unit, wherein the base portion 17, the two hinged portions 19 of the stator 13 are hinged.
    The guide member 20 which is fixed to a stop plate 26 of the base portion 17, in guide structures 21 on the Justierplatte 15, for example in the manner of a dovetail connection, inserted and is then fixed with the handwheel 16 in the operating position.
    In order to install the disc motor 10 of the drive unit according to the invention for the first time in an existing bicycle, the front wheel (same applies to the rear wheel) must be removed. Then the possibly present brake disc is replaced by the rotor disk 11 of the drive unit. Furthermore, the possibly existing brake caliper is removed and screwed in place of the adapter 14 on the receptacle 7 for the brake caliper. Afterwards, the adjusting plate 15 is loosely screwed onto the adapter 14 in order to be able to make adjustments in the vertical and horizontal directions. Now, the annular stator 13 is unfolded and pushed over the rotor disk 11, it being important to ensure that the guide element 20, which must be inserted into the guide structures 21 of the adjustment plate 15, engages in the dovetail connection. For the adjustment to be performed only once, the drive unit has adjusting inserts 23 (see FIG. 7), which are clipped onto the rotor disk 11 during the initial installation for fixing a radial air gap between the rotor disk 11 and the annular stator 13. Thereafter, the hinged portions 19 of the stator 13 are folded and fixed with the help of arranged on the hinged portions 19 locking elements 25 and the slide-U-shaped locking element 24 (see FIG. 6) to each other.
    Now all screws on the adjustment plate 15 and the stop plate 26 are tightened. Thereafter, the stator is opened, the adjustment inserts 23 removed and fixed the hinged sections 19 with the manually push-on locking element 24 in the operating position.
    To remove the annular stator 13 later this must only be opened and withdrawn from the dovetail connection. A new adjustment during reuse is then no longer necessary.
    The embodiment variant shown in FIGS. 5, 6 and 7 has on the outer circumference of the annular stator 13, preferably in the region of the hinged sections 19, a rechargeable energy store 22, for example a lithium-ion battery. About the joints between the base portion 13 and the hinged sections 19 guided, flexible electrical connection cables are not shown.
    Advantageously, in this embodiment with the annular stator 13 at the same time the rechargeable energy storage 22 can be removed from the bicycle and is thus protected from damage and theft. Furthermore, no wiring between the disc motor 10 and the energy storage on the bike must be laid, since they are already integrated in the compact unit.
    The motor control arranged in the housing 18 can be wireless, for example via mobile communication means and / or via torque sensors in the pedals of the bicycle and wireless signal transmission.
    According to the invention, the disk motor 10 can also be used as an engine brake and unit for energy recovery. A corresponding control can be wireless via a sensor in the brake lever, including wireless signal transmission.
    The disk motor 10 may preferably be designed as a brushless synchronous machine.
