Description

Einrichtung zum Hochfahren eines Verbrennungsmotors in einem Fahrzeug mit Hybridantrieb, wobei ein Steppermotor als Startermotor eingesetzt wird, um den Verbrennungsmotor hochzufahren. Wobei die für den Stepperbetrieb notwendigen Magnete sich auf der Welle des Verbrennungsmotors befinden können.Facility for starting up an internal combustion engine in a vehicle with hybrid drive, wherein a stepper motor is used as a starter motor to the internal combustion engine boot. Whereby necessary for stepper operation Magnets can be located on the shaft of the internal combustion engine.

Stand der TechnikState of the art

Auf dem KFZ-Markt werden Fahrzeuge mit Hybridantrieb angebotenOn The car market offers vehicles with hybrid drive

Bei geringen Geschwindigkeiten wird das Fahrzeug durch einem Elektromotor (E1 Motor) angetriebenat low speeds, the vehicle is powered by an electric motor (E1 engine) driven

Bei höheren Geschwindigkeiten oder bei erhöhten Leistungsbedarf (große Beschleunigung, Bergfahrten u. ä.) wird auf den Verbrennungsmotor umgeschaltet.at higher speeds or at increased power requirements (high acceleration, mountain driving and the like) switched to the combustion engine.

Um vom E1 Motor auf den Verbrennungsmotor umschalten zu können, muß der Verbrennungsmotor hochgefahren werden. Dieses kann durch einen zusätzlichen elektrische betrieben Startermotor (E2 Motor) erfolgen, oder durch den E1 Motor.Around to switch from the E1 engine to the combustion engine, the internal combustion engine must be started up. This can powered by an additional electric starter motor (E2 Engine), or by the E1 engine.

In der Offenlegungsschrift DE 10 2007 011 798 A1 2007.11.15 wird aufgezeigt wie die Umschaltung zwischen dem Elektromotor und der Verbrennungsmaschine erfolgen kann.In the published patent application DE 10 2007 011 798 A1 2007.11.15 shows how switching between the electric motor and the combustion engine can be done.

Bei diesem System wird der Verbrennungsmotor durch mechanische Komponenten mit einem elektrischen Startermotor verbunden. Es gibt keine unmittelbare Kopplung zwischen dem Startermotor und dem Verbrennungsmotor. Die Leistung des Startermotors steht nicht zu 100% dem Verbrennungsmotor zur Verfügung.at In this system, the internal combustion engine is replaced by mechanical components connected to an electric starter motor. There is no immediate Coupling between the starter motor and the internal combustion engine. The Power of the starter motor is not 100% the internal combustion engine to disposal.

Die zwischengeschalteten Komponenten zwischen Starter und Verbrennungsmotor verbrauchen einen Teil der vom Startermotor zur Verfügung gestellten Leistung. Es ergibt sich insgesamt eine Verschlechterung des Wirkungsgrades.The Intermediate components between starter and internal combustion engine consume part of the engine provided by the starter motor Power. Overall, there is a deterioration in the efficiency.

Um den Verbrennungsmotor in einer kurzen Zeit (< 2 sec) hochzufahren, ist ein hohes Drehmoment erforderlich. Ein bürstenbehafteter Motor ist hier im Nachteil.Around Starting the combustion engine in a short time (<2 sec) is a high one Torque required. A brushed motor is here in disadvantage.

Während der Lebensdauer eines Hybridfahrzeuges sind 500 000 bis über 2 000 000 Startvorgänge zu erwarten.While The lifespan of a hybrid vehicle is 500,000 to over 2 000 000 launches are expected.

Die bekannten – bürstenbehafteten – Startermotoren erfüllen diese Anforderung nicht.The known - brushed - starter motors do not fulfill this requirement.

Aufgabenstellungtask

Es ist eine Vorrichtung zu entwickeln, welche die vorgenannten Probleme nicht aufweist.It is a device to develop which the above problems does not have.

Wenn ein Steppermotor als Startermotor verwendet wird, ergeben sich u. a. folgende Vorteile:

  • – Bauartbedingt hat der Stepper ein hohes Drehmoment.
  • – da der Stepper keine verschleißbehaftete Bürsten benötigt, erhöht sich die Lebensdauer
  • – die Abmessungen des Motors können den räumlichen Gegebenheiten angespaßt werden.
  • – wenn die Magnete des Steppers direkt auf die anzutreibende Welle aufgebracht werden, ist eine direkte Kopplung zwischen dem Stepper als Startermotor und dem Verbrennungsmotor möglich.
When a stepper motor is used as a starter motor, there are the following advantages:
  • - Due to the design of the stepper has a high torque.
  • - Since the stepper does not require wear-prone brushes, the life increases
  • - The dimensions of the engine can be adapted to the spatial conditions.
  • - If the magnets of the stepper are applied directly to the driven shaft, a direct coupling between the stepper as a starter motor and the internal combustion engine is possible.

B. über einen Zahnriemen, welcher über einen Spanner gespannt wird.Usually, via the drive shaft ( 14 ) the internal combustion engine ( 16 ) powered up by an additional E2 engine. The connection between the drive shaft ( 14 ) and the E2 engine is z. B. via a toothed belt, which is stretched over a tensioner.

Die Zeichnung 2 zeigt ein Beispiel, wie ein Stepper mit der Antriebswelle (14 Zeichnung 1) gekoppelt werden kann.Drawing 2 shows an example of how a stepper with the drive shaft ( 14 Drawing 1) can be coupled.

Der Stator (22) ist mechanisch fest mit Fahrzeug verbunden. Die dem Stepper zugeordneten Magnete werden fest auf die Antriebswelle montiert und diese Einheit ist der Rotor mit Magneten (24) des Steppers.The stator ( 22 ) is mechanically fixed to the vehicle. The magnets associated with the stepper are fixedly mounted on the drive shaft and this unit is the rotor with magnets ( 24 ) of the stepper.
