Description

Die Erfindung bezieht sich auf ein Antriebs-Aggregat, insbesondere zum Antrieb eines Fahrzeuges, nach dem Oberbegriff des Patentanspruches 1.The invention relates to a drive unit, in particular for driving a vehicle, according to the preamble of claim 1.

Aus der FR-A-1 463 799 ist ein Antriebs-Aggregat mit einem Fahrmotor bekannt, dem ein Hilfsmotor zum wahlweisen Antrieb von Hilfsaggregaten zugeordnet ist. Der im Bedarfsfall zum Antrieb der Hilfsaggregate dienende Hilfsmotor ist seitlich des Fahrmotors angeordnet. Die Hilfsaggregate sind von den freien Stirnbereichen beider Motore beabstandet angeordnet und baulich im wesentlichen dem Hilfsmotor zugeordnet. Nachteilig hierbei ist der erhebliche Einbauraum.From FR-A-1 463 799 a drive unit with a traction motor is known, to which an auxiliary motor for optionally driving auxiliary units is assigned. The auxiliary motor, which is used to drive the auxiliary units when necessary, is arranged on the side of the traction motor. The auxiliary units are arranged at a distance from the free end areas of both motors and are essentially structurally assigned to the auxiliary motor. The disadvantage here is the considerable installation space.

Der Erfindung liegt die Aufgabe zugrunde, für ein gattungsgemäßes Antriebs-Aggregat eine Anordnung eines Hilfsmotors mit geringerem Bedarf an Einbauraum aufzuzeigen.The invention has for its object to show an arrangement of an auxiliary motor with less need for installation space for a generic drive unit.

Diese Aufgabe wird gemäß dem Kennzeichen des Patentanspruches 1 dadurch gelöst, daß in einem freien Stirnbereich des Fahrmotors als Hilfsmotor ein als Brennkraftmaschine ausgebildeter Einsternmotor angeordnet ist. Eine besonders vorteilhaft platzsparende Anordnung ist nach Anspruch 2 mit einem Einsternmotor erreicht, der als 4-Zylinder-2-Takt-Motor mit einem Kurbelschlaufen-Triebwerk ausgebildet ist. Mit diesem beispielsweise in der EP-A-0 187 930 näher beschriebenen Einsternmotor ist für eine platzsparende Anordnung ein kurzbauender, kompakter und leistungsstarker Hilfsmotor erzielt. Die Erfindung ist jedoch nicht nur hinsichtlich der Baugröße des Hilfsmotors von Vorteil. Sie ist auch hinsichtlich der Gesamt-Anordnung von erheblichem Vorteil dadurch, daß im stirnseitigen Endbereich des Fahrmotors vorgesehene, gegebenen Einbauraum nutzend angeordnete Hilfsaggregate verbleiben können und damit eine gesonderte, zusätzlichen Einbauraum erfordernde Anordnung entfällt.This object is achieved in accordance with the characterizing part of patent claim 1 in that a single-star motor designed as an internal combustion engine is arranged in a free end region of the traction motor as an auxiliary motor. A particularly advantageous space-saving arrangement is achieved according to claim 2 with a single-star engine, which is designed as a 4-cylinder 2-stroke engine with a crank loop engine. With this single-star motor, which is described in more detail, for example, in EP-A-0 187 930, a short, compact and powerful auxiliary motor is achieved for a space-saving arrangement. However, the invention is advantageous not only in terms of the size of the auxiliary motor. It is also of considerable advantage with regard to the overall arrangement in that auxiliary units provided in the front end region of the traction motor can be used, provided that installation space can be used, and thus a separate arrangement requiring additional installation space is omitted.

Diese vorteilhafte Anordnung wird in einfacher Weise zusätzlich dadurch unterstützt, daß der Einsternmotor unter Zwischenschaltung einer schaltbaren Kupplung fluchtend mit einer Triebwerkswelle des Fahrmotors angeordnet ist.This advantageous arrangement is additionally supported in a simple manner in that the single-star motor is arranged in alignment with an engine shaft of the traction motor with the interposition of a switchable clutch.

In weiterer Ausgestaltung der erfindungsgemäßen Anordnung wird zur Erzielung einer kurzen Gesamtlänge des Antriebs-Aggregates nach Anspruch 3 vorgeschlagen, daß die Kupplung außenumfänglich in Drehverbindung steht mit Abtriebsscheiben von in mehreren Ebenen im freien Stirnbereich des Fahrmotors vorgesehenen Hüllgetrieben zum Antrieb der Hilfsaggregate.In a further embodiment of the arrangement according to the invention, in order to achieve a short overall length of the drive unit according to claim 3, it is proposed that the coupling be in rotary connection on the outside with driven disks of enveloping gears provided in several planes in the free end region of the drive motor for driving the auxiliary units.

Die vorbeschriebene schaltbare Kupplung kann so gestaltet sein, daß über diese wahlweise die Hilfsaggregate durch den Einsternmotor bei Stillstand, Leerlauf oder evtl. bei starker Belastung des Fahrmotors angetrieben sind. Nach Anspruch 4 ist für die schaltbare Kupplung jedoch auch eine Betriebsweise denkbar derart, daß bei Bedarf lediglich ein Teil der Hilfsaggregate von dem Einsternmotor angetrieben wird. Dies insbesondere für den Fall, daß ein oder mehrere dieser gesondert wahlweise angetriebenen Hilfsaggregate eine erhöhte Leistung abzugeben haben, die bei Beibehaltung der gegebenen Drehzahl des Fahrmotors nicht zu erbringen ist, wie beispielsweise verstärkte Klimaleistung und/oder erhöhter elektrischer Verbrauch aus dem Bordnetz bei geringer Fahrgeschwindigkeit oder einer Stop-and-Go-Fahrweise des Fahrzeuges.The above-described switchable clutch can be designed so that the auxiliary units can be driven by the single-star engine when the vehicle is at a standstill, idling or possibly under a heavy load on the drive motor. According to claim 4, however, an operating mode is also conceivable for the switchable clutch such that, if necessary, only a part of the auxiliary units is driven by the single-star motor. This especially for the case that one or more of these separately selectively driven auxiliary units have to deliver an increased power that cannot be achieved while maintaining the given speed of the traction motor, such as, for example, increased air conditioning power and / or increased electrical consumption from the vehicle electrical system at low driving speed or a stop -and-go driving style of the vehicle.

Es wird schließlich vorgeschlagen, daß Einsternmotor und schaltbare Kupplung einen Nachrüstsatz bilden.Finally, it is proposed that the single-star motor and the switchable clutch form a retrofit kit.

Ein zum Antrieb eines nicht dargestellten Fahrzeuges dienendes Aggregat 1 umfaßt einen zum Fahrzeug-Antrieb dienenden Fahrmotor 2 mit zahlreichen, im stirnseitigen Endbereich angeordneten Hilfsaggregaten. An Hilfsaggregaten sind vorgesehen eine Kühlmittelpumpe 3 mit einer Antriebsscheibe 4 und eine Lenkhilfepumpe 5 mit einer Antriebsscheibe 6. Die Antriebsscheiben 4 und 6 liegen mit einer der Triebwerkswelle 7 des Fahrmotors 2 zugeordneten Abtriebsscheibe 8 in einer Ebene eines Hüllgetriebes 9. Weitere Hilfsaggregate sind ein Generator 10 mit einer Antriebsscheibe 11 und ein Klimakompressor 12 mit einer Antriebsscheibe 13. Die Antriebsscheiben 11 und 13 liegen mit einer weiteren, der Triebwerkswelle 7 zugeordneten Abtriebsscheibe 14 in einer anderen Ebene eines zweiten Hüllgetriebes 15.An assembly 1 serving to drive a vehicle, not shown, comprises a traction motor 2 serving to drive the vehicle, with numerous auxiliary assemblies arranged in the end region. Auxiliary units are provided with a coolant pump 3 with a drive pulley 4 and a power steering pump 5 with a drive pulley 6. The drive pulleys 4 and 6 lie with a driven pulley 8 assigned to the drive shaft 7 of the traction motor 2 in one plane of an enveloping transmission 9. Further auxiliary units are a generator 10 with a drive pulley 11 and an air conditioning compressor 12 with a drive pulley 13. The drive pulleys 11 and 13 are located with a further, the output shaft 14 assigned to the engine shaft 7 in a different plane of a second enveloping gear 15.

Mit der Triebwerkswelle 7 des Fahrmotors 2 ist unter Zwischenschaltung einer schaltbaren Kupplung 16 fluchtend ein Hilfsmotor 17 angeordnet, der dem wahlweisen Antrieb der vorgenannten Hilfsaggregate 3, 5, 10, 12 dient.With the engine shaft 7 of the traction motor 2, with the interposition of a switchable clutch 16, an auxiliary motor 17 is arranged in alignment, which serves to selectively drive the aforementioned auxiliary units 3, 5, 10, 12.

Zur Erzielung einer kurzen Gesamt-Baulänge des Antriebs-Aggregates 1 ist der im freien Stirnbereich des Fahrmotors 2 angeordnete Hilfsmotor 17 als Einsternmotor 18 gestaltet. Um mit platzsparender Anordnung einen kurzbauenden, kompakten und leistungsstarken Hilfsmotor 17 zu erreichen, ist der Einsternmotor 18 als ein 4-Zylinder-2-Takt-Motor mit Kurbelschlaufen-Triebwerk (EP-A-0 187 930) ausgeführt.To achieve a short overall length of the drive unit 1, the auxiliary motor 17 arranged in the free end region of the drive motor 2 is designed as a single-star motor 18. In order to achieve a compact, high-performance auxiliary motor 17 with a space-saving arrangement, the single-star motor 18 is designed as a 4-cylinder, 2-stroke engine with a crank-loop engine (EP-A-0 187 930).

Zum wahlweisen Antrieb der vorgenannten Hilfsaggregate 3, 5, 10, 12 steht die schaltbare Kupplung 16 außenumfänglich in drehfester Verbindung mit den Abtriebsscheiben 8 und 14 der Hüllgetriebe 9 und 15 der in zwei Gruppen aufgeteilten Hilfsaggregate 3, 5 und 10, 12. Die Kupplung 16 ist in der Weise schaltbar, daß entweder beide Gruppen der Hilfsaggregate 3, 5 und 10, 12 oder aber je nach Bedarf eine der Gruppen 3, 5 bzw. 10, 12 über den Einsternmotor 18 betreibbar ist.For the optional drive of the aforementioned auxiliary units 3, 5, 10, 12, the switchable clutch 16 is connected on the outside in a rotationally fixed connection to the driven disks 8 and 14 of the cladding gears 9 and 15 of the auxiliary units 3, 5 and 10, 12 divided into two groups. The clutch 16 is switchable in such a way that either both groups of auxiliary units 3, 5 and 10, 12 or, depending on requirements, one of groups 3, 5 and 10, 12 can be operated via the single-star motor 18.

Der am Fahrmotor 2 angeordnete Einsternmotor 18 kann mit der schaltbaren Kupplung 16 auch als Nachrüstsatz ausgebildet sein.The single-star motor 18 arranged on the traction motor 2 can also be designed with the switchable clutch 16 as a retrofit kit.
