Description

Ele troantriebssystem für ein Fahrzeug Electric drive system for a vehicle
Die Erfindung betrifft ein Elektroantriebssystem für ein Fahrzeug, an dem ein Antriebsrad unmittelbar oder mittelbar an einem Rahmen des Fahrzeuges drehbar gelagert ist. Das Elektroantriebssystem beinhaltet eine Kraftübertragungseinheit, die aus Radachse, Radlager und Radnabe, auf der das Antriebsrad mit seiner Felge befestigt ist, besteht, einen Elektroantrieb mit einem Elektromotor, der mit dem Antriebsrad antreibend verbunden ist, und eine Steuereinheit, die mit dem Elektromotor e- lektrisch leitend verbunden ist und eine Verbindung zu einer Stromversorgungseinheit und zu einem Stellglied aufweist.The invention relates to an electric drive system for a vehicle on which a drive wheel is rotatably mounted directly or indirectly on a frame of the vehicle. The electric drive system includes a power transmission unit, which consists of the wheel axle, wheel bearing and wheel hub, on which the drive wheel is fastened with its rim, an electric drive with an electric motor, which is drivingly connected to the drive wheel, and a control unit, which is connected to the electric motor. is electrically conductively connected and has a connection to a power supply unit and to an actuator.
Herkömmliche AntriebsSysteme, die noch mit einem Verbrennungsmotor ausgestattet sind, weisen den Nachteil auf, dass ihr Wirkungsgrad unzureichend und dass eine hohe Emissionen an schäd- liehen Abgasen und Lärm zu verzeichnen ist, was insbesondere in Ballungszentren problematisch ist.Conventional drive systems that are still equipped with an internal combustion engine have the disadvantage that their efficiency is inadequate and that there are high emissions of harmful exhaust gases and noise, which is particularly problematic in metropolitan areas.
Außerdem ist der verwendete fossile Treibstoff nicht zukunftsträchtig ist, d. h. dieser Treibstoff wird in Zukunft für die Antriebssysteme auf Verbrennungsbasis nicht mehr zur Verfügung stehen.In addition, the fossil fuel used is not promising, i. H. this fuel will no longer be available for combustion-based drive systems in the future.
Einerseits besteht wegen der begrenzten Verfügbarkeit fossiler Treibstoffe das Erfordernis, Fahrzeuge mit alternativen An- triebssysteme aus- oder umzurüsten. Dem steht jedoch der hohe Kosten- und technische Aufwand, der bei einer Erstausstattung oder Umrüstung betrieben werden uss, entgegen. Anderseits besteht für alternative AntriebsSysteme, besonders für Elektroantriebssysteme, die Anforderung nach einem solch hohem Wirkungsgrad des Triebwerkes, der den herkömmlicher An- triebssysteme möglichst übersteigt oder zumindest erreicht.On the one hand, due to the limited availability of fossil fuels, there is a need to equip or retrofit vehicles with alternative drive systems. However, this is countered by the high cost and technical effort that must be carried out with initial equipment or retrofitting. On the other hand, for alternative drive systems, especially for electric drive systems, there is a requirement for such a high degree of efficiency of the engine, which as far as possible exceeds or at least achieves the conventional drive systems.
Es ist beim Stand der Technik festzustellen, dass es für Elektroantriebssysteme noch nicht gelungen ist, die Kosten für eine Erstausrüstung oder einen Umbau der Fahrzeuge durch einen ein- fachen und preiswerten Austausch von Baugruppen günstig zu gestalten und einen hinreichenden Wirkungsgrad zu gewährleisten.In the state of the art, it can be said that it has not yet been possible for electric drive systems to cheaply design the costs for original equipment or a conversion of the vehicles by simply and inexpensively replacing assemblies and to ensure sufficient efficiency.
Somit wird ein großer weltweiter Markt, insbesondere in solchen Ländern in denen Zweiradfahrzeuge stark verbreitet sind, wie zum Beispiel in China, Taiwan aber auch in Europa, wie z.B. in Italien, Spanien, nach wie vor mit Fahrzeugen beliefert, die die oben dargestellten Nachteile zeigen.Thus, a large worldwide market, especially in those countries in which two-wheeled vehicles are widely used, such as in China, Taiwan but also in Europe, such as in Italy, Spain, continue to be supplied with vehicles that have the disadvantages outlined above.
Beim Stand der Technik wird aber deutlich, dass Lösungen zu einzelnen Bauteilen von neuen Antriebssystemen, insbesondere bei stromsparenden Elektromotoren, weit fortgeschritten sind.However, the state of the art makes it clear that solutions for individual components of new drive systems, particularly in the case of energy-saving electric motors, are well advanced.
Hier wird auf die europäische Patentschrift EP 0331 180 Bl verwiesen, in der ein Elektromotor mit hohem Wirkungsgrad be- schrieben wird, der solche Drehzahlen, verbunden mit entsprechenden Drehmomenten realisiert, bei denen ein Antriebsrad direkt angetrieben werden kann, ohne dass ein Getriebe zwischen Motor und Antriebsrad geschalten werden muss.Reference is made here to the European patent EP 0331 180 B1, in which an electric motor is described with high efficiency, which realizes such speeds, combined with corresponding torques, at which a drive wheel can be driven directly without a gear between motor and Drive wheel must be switched.
Der Vorteile solcher Realisierungen, zum Beispiel, die Möglichkeit der direkten Ankopplung und der damit verbundene hohe Wirkungsgrad des Motors, sowie durch die damit ebenfalls verbünde- ne verringerte Bauelementezahl, welche geringere Kosten und erhöhte Zuverlässigkeit bewirkt, können zum gegenwärtigen Zeitpunkt nur bei einer Erstausstattung von Neufahrzeugen eingesetzt werden, wobei dabei der Herstellungs- und Montageaufwand eine erhebliche Größe aufweist, der insbesondere bei der Zusammenschaltung der am Fahrzeug verteilten Bauelemente des Elekt- roantriebes entsteht. Ein Nachrüsten derartiger Elektroantriebe bei Neu- oder Altfahrzeugen ist entweder nicht möglich oder mit unvertretbar hohem Aufwand verbunden.The advantages of such implementations, for example, the possibility of direct coupling and the associated high efficiency of the motor, as well as the associated A reduced number of components, which results in lower costs and increased reliability, can currently only be used for the initial fitting of new vehicles, the manufacturing and assembly expenditure being of a considerable size, which is particularly important when interconnecting the components of the electrical system distributed on the vehicle. roantriebes emerges. Retrofitting such electric drives in new or old vehicles is either not possible or involves an unacceptably high outlay.
Der Erfindung liegt die Aufgabenstellung zugrunde, Fahrzeuge mit herkömmlichen Verbrennungsmotor oder ähnlichen Antriebsystemen mit geringem Kosten- und technischen Aufwand zu Fahrzeugen mit energiesparenden und bezüglich Lärm und Abgas emmisi- onsfreien Antriebssystemen aus- oder umzurüsten.The invention is based on the object of equipping or converting vehicles with conventional internal combustion engines or similar drive systems to vehicles with energy-saving drive systems which are emission-free in terms of noise and exhaust gas and with low cost and technical outlay.
Die erfindungsgemäße Lösung der Aufgabenstellung besteht darin, dass der Elektromotor so ausgeführt wird, dass dieser die Kraftübertragungseinheit vollständig enthält.The solution to the problem according to the invention is that the electric motor is designed so that it completely contains the power transmission unit.
Hierbei ist einerseits der Stator, an dem die elektronisch kommmutierte Wicklungen angeordnet sind und der die Achse repräsentiert, unmittelbar oder mittelbar an dem Rahmen des Fahrzeuges verbunden und anderseits ist der Rotor, an dem die Per- manentmagneten angeordnet sind und der die Radnabe repräsentiert, mit dem Antriebsrad verbunden.On the one hand, the stator, on which the electronically commutated windings are arranged and which represents the axle, is connected directly or indirectly to the frame of the vehicle and, on the other hand, the rotor, on which the permanent magnets are arranged and which represents the wheel hub, is also connected connected to the drive wheel.
Weiterhin wird der Rotor jeweils in dem ersten und/oder zweiten Lager des Elektromotors gelagert, welches jeweils ein Lager des Antriebsrades repräsentiert.Furthermore, the rotor is mounted in the first and / or second bearing of the electric motor, which each represents a bearing of the drive wheel.
Diese Lösung zielt durch die Vermeidung von einer extra ausge- führten Kraftübertragungseinheit und einem Getriebe und durch den Ersatz eines hochdrehenden Elektromotors mittels des direkt antreibenden, niedrig drehenden Motors darauf ab, dass neben des offensichtlichen geringeren technischen und kostenmäßigen Aufwandes eine vielfach höhere Standzeit und Betriebssicherheit erreicht werden.This solution aims by avoiding an extra led the power transmission unit and a gearbox and by replacing a high-speed electric motor by means of the direct-driving, low-speed motor to ensure that, in addition to the obvious lower technical and cost expenditure, a much longer service life and operational reliability are achieved.
Bei einigen Fahrzeugen erfolgt die mittelbare Lagerung mittels einer Radschwinge, welche einerseits über eine Schwingenlage- rung und andererseits über eine Federlagerung, beispielsweise einer Zentralfederlagerung oder eine Doppelfederlagerung mit dem Rahmen des Fahrzeuges verbunden ist.In some vehicles, the indirect mounting is carried out by means of a wheel swing arm, which is connected to the frame of the vehicle on the one hand via a swing arm mounting and on the other hand via a spring mounting, for example a central spring mounting or a double spring mounting.
Eine günstige Variante der erfindungsgemäßen Lösung der Aufga- benstellung wird nun dadurch erreicht, dass bei der mittelbar ausgeführten Lagerung des Antriebsrades mittels einer Radschwinge eine zum Elektroantriebssystem zugehörige Baugruppe so ausgeführt wird, dass die zur Baugruppe zugehörigen Teile E- lektromotor und Steuereinheit mechanisch mit dem ebenfalls zur Baugruppe zugehörigen Teil Radschwinge verbunden sind und dass diese Baugruppe anstelle einer herkömmlicher Radschwinge mit Kraftübertragungseinheit angeordnet wird.A favorable variant of the solution to the task according to the invention is now achieved in that, in the case of the drive wheel being mounted indirectly, a component belonging to the electric drive system is designed by means of a wheel rocker so that the parts belonging to the component are mechanically connected to the electric motor and control unit part belonging to the assembly swing arm and that this assembly is arranged instead of a conventional swing arm with power transmission unit.
Eine spezielle Ausführung der günstigen Variante der erfin- dungsgemäßen Lösung wird dadurch erreicht, dass die Radschwinge des Elektroantriebssystem so gestaltet wird, dass sie einen Hohlraum aufweist, in dem die Steuereinheit angeordnet ist.A special embodiment of the inexpensive variant of the solution according to the invention is achieved in that the wheel rocker of the electric drive system is designed in such a way that it has a cavity in which the control unit is arranged.
Beispielsweise kann die Radschwinge als ein wasserdichter Rah- menträger ausgeführt werden, in dessen Hohlraum die Steuereinheit untergebracht ist. Eine weitere Ausführung der günstigen Variante der erfindungsgemäßen Lösung wird dadurch erreicht, dass das Elektroantriebssystem für Zweiradfahrzeuge mit einem Hinterradantrieb dadurch ausgeführt wird, dass die Radschwinge als Hinterradschwinge aufgebaut ist.For example, the wheel swing arm can be designed as a watertight frame support, in the cavity of which the control unit is accommodated. A further embodiment of the inexpensive variant of the solution according to the invention is achieved in that the electric drive system for two-wheeled vehicles with a rear-wheel drive is designed in such a way that the wheel swing arm is constructed as a rear wheel swing arm.
Eine angepasste Ausführung der günstigen Varianten der erfindungsgemäße Lösung besteht darin, dass die Radschwinge einarmig und gekröpft ausgeführt ist. Hierbei wird die Schwingenlagerung mittig zur radialen Mittellinie des Antriebsrades an einem gekröpften ersten Ende der Radschwinge angeordnet.A modified version of the favorable variants of the solution according to the invention consists in that the wheel rocker is designed with one arm and cranked. Here, the rocker bearing is arranged centrally to the radial center line of the drive wheel at a cranked first end of the wheel rocker.
Weiterhin ist an einem gekröpften zweiten Ende der Radschwinge der Elektromotor angeordnet, an welchem das Antriebsrad befes- tigt wird.Furthermore, the electric motor, to which the drive wheel is attached, is arranged on a cranked second end of the wheel rocker.
Ebenfalls eine angepasste Ausführung der günstigen Variante der erfindungsgemäßen Lösung ergibt sich dadurch, dass die Radschwinge so gekröpft ist, dass das an ihrem zweiten Ende ange- ordnete Antriebsrad mit seiner radialen Mittellinie mit der Mittellinie des gekröpften ersten Endes der Radschwinge fluchtet.A modified version of the cheap variant of the solution according to the invention also results from the fact that the wheel rocker is cranked in such a way that the drive wheel arranged at its second end is aligned with its radial center line with the center line of the cranked first end of the wheel rocker.
Die Erfindung soll nachfolgend anhand eines Ausführungsbeispie- les näher erläutert werden.The invention will be explained in more detail below on the basis of an exemplary embodiment.
Die zugehörige Zeichnungsfigur zeigt eine Zusammenstellung der Bestandteile des Elektroantriebssyste s 10 bei der mittelbar ausgeführten Lagerung des Antriebsrades 4 mittels einer Rad- schwinge 1. Die Radschwinge 1 weist an seinem ersten gekröpften Ende die mittig angeordnete Schwingenlagerung 7 auf. In dem durch den gekröpften Zustand der Radschwinge schräg verlaufenden mittleren Teil ist die Befestigung 6 für die Zentralfederung 5 ersichtlich. In diese wird die Zentralfederung 5 aufgenommen.The associated drawing figure shows a compilation of the components of the electric drive system 10 in the indirectly designed mounting of the drive wheel 4 by means of a wheel rocker 1. The wheel rocker 1 has the centrally arranged rocker bearing 7 at its first cranked end. The attachment 6 for the central suspension 5 can be seen in the central part which runs obliquely due to the cranked state of the wheel rocker. The central suspension 5 is accommodated in this.
Sie realisiert einerseits eine Schwingungsdämpfung. Andererseits realisiert sie zusammen mit der Schwingenlagerung 7 die Befestigung an dem nicht näher dargestellten Rahmen eines eben- falls nicht näher dargestellten Fahrzeuges.On the one hand, it realizes vibration damping. On the other hand, together with the rocker bearing 7, it realizes the attachment to the frame, not shown in more detail, of a vehicle, also not shown in detail.
Am zweiten gekröpften Ende der Radschwinge 1 ist der Stator 2 als ein Bestandteil des Motors 9 befestigt. An dem Rotor 3 wird unmittelbar das Antriebrad 4 verschraubt.The stator 2 is fastened to the second cranked end of the wheel rocker 1 as a component of the motor 9. The drive wheel 4 is screwed directly onto the rotor 3.
Die Steuerelektronik 8 ist im Mittelteil der Radschwinge 1 befestigt bzw. ist direkt in die Schwinge integriert. Weiterhin ist diese Steuerelektronik 8 einerseits mit dem Stator 2 des Elektromotors 9 elektrisch verbunden.The control electronics 8 is fastened in the middle part of the wheel swing arm 1 or is integrated directly into the swing arm. Furthermore, this control electronics 8 is on the one hand electrically connected to the stator 2 of the electric motor 9.
