Abstract
Description
Die Erfindung betrifft einen Fahrantrieb mit einem Verbrennungsmotor und einem Getriebe mit stufenloser Wandlung, dessen für die stufenlose Wandlung vorgesehene Getriebekomponenten zusammen mit Komponenten zur Erzielung einer Differentialwirkung Bestandteile eines Kompaktgetriebes sind, das eingangsseitig an den Verbrennungsmotor angeflanscht ist und ausgangsseitig zwei zueinander fluchtende, jeweils mit einem Radantrieb gekoppelte Abtriebsrotoren aufweist und das zur gemeinsamen Lagerung mit dem Verbrennungsmotor an einem Fahrzeugrahmen ausgebildet ist.The The invention relates to a traction drive with an internal combustion engine and a continuously variable transmission, whose for the continuously variable transmission components provided together with components for achieving a differential effect components a compact gearbox, the flanged on the input side to the internal combustion engine is and on the output side two mutually aligned, each with a Has wheel drive coupled output rotors and the common storage is formed with the internal combustion engine on a vehicle frame.
Ein
gattungsgemäßer Fahrantrieb ist in der
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, einen Fahrantrieb der eingangs genannten Art zur Verfügung zu stellen, dessen Einsatzbereich erweitert ist.Of the The present invention is based on the object, a traction drive to provide the type mentioned, whose Field of application is expanded.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Radantriebe als von dem Kompaktgetriebe getrennte, separat am Fahrzeugrahmen befestigbare Baueinheiten ausgeführt sind und sich zwischen den Abtriebsrotoren des Kompaktgetriebes und den Radantrieben Fluchtungs- und Winkelfehler ausgleichende Drehmoment-Übertragungsmittel befinden.These The object is achieved according to the invention that the wheel drives as separate from the compact gearbox, separately executed on the vehicle frame attachable units are and between the output rotors of the compact gear and the wheel drives misalignment and angle error compensating torque transmission means are located.
Der erfindungswesentliche Gedanke besteht demnach darin, das stufenlose Getriebe von den Radantrieben zu trennen, mithin die Radantriebe außerhalb des Kompaktgetriebes anzuordnen. Durch Anpassung der Radantriebe an den gewünschten Einsatzzweck, beispielsweise durch Zwischenschaltung von ein- oder mehrstufigen Untersetzungsgetrieben, Einbau von Radbremsen, etc., kann daher die aus dem Verbrennungsmotor und dem Kompaktgetriebe bestehende Baugruppe, ohne Änderungen daran vornehmen zu müssen, auf vielfältige Weise Verwendung finden.Of the Thought essential to the invention is therefore the stepless To separate transmission from the wheel drives, hence the wheel drives to be arranged outside of the compact gearbox. By adaptation the wheel drives to the desired application, for example through the interposition of single or multistage reduction gears, Installation of wheel brakes, etc., may therefore be from the internal combustion engine and the compact transmission assembly, without changes to have to make use in a variety of ways Find.
Gemäß einer vorteilhaften Weiterbildung der Erfindung wird vorgeschlagen, dass die Drehmoment-Übertragungsmittel als drehstarre Ausgleichkupplung, drehelastische Kupplung oder als Gelenk ausgebildet sind.According to one advantageous development of the invention it is proposed that the torque-transmitting means as a torsionally stiff compensation coupling, torsionally flexible coupling or are designed as a hinge.
Der Verbrennungsmotor ist mit Vorteil in Fahrzeuglängsrichtung angeordnet und das Kompaktgetriebe als hydrostatisches Kompaktgetriebe ausgebildet, das eine zu einer Antriebswelle des Verbrennungsmotors koaxiale Hydropumpe aufweist, die hydraulisch in Parallelschaltung an zwei rechtwinklig zur Hydropumpe angeordnete Hydromotoren angeschlossen ist. Gleichwohl ist es auch möglich, dass das hydrostatische Kompaktgetriebe nur einen einzelnen Hydromotor enthält, dem dann ein mechanisches Differentialgetriebe nachgeschaltet ist.Of the Combustion engine is advantageous in the vehicle longitudinal direction arranged and the compact gear designed as a hydrostatic compact transmission, the one coaxial to a drive shaft of the internal combustion engine Hydraulic pump, the hydraulically connected in parallel to two connected at right angles to the hydraulic pump arranged hydraulic motors is. However, it is also possible that the hydrostatic Compact gearbox contains only a single hydraulic motor, then followed by a mechanical differential gear.
Gemäß einer anderen vorteilhaften Ausführungsvariante der Erfindung kann der Verbrennungsmotor in Fahrzeuglängsrichtung angeordnet und das Kompaktgetriebe als elektrisches Kompaktgetriebe ausgebildet sein, das einen zu einer Antriebswelle des Verbrennungsmotors koaxialen Generator aufweist, der elektrisch in Parallelschaltung an zwei rechtwinklig zum Generator angeordnete Elektromotoren angeschlossen ist. Analog zur oben beschriebenen Variante eines hydrostatischen Kompaktgetriebes mit mechanischem Differentialgetriebe ist es auch hier möglich, nur einen einzelnen elektrischen Fahrmotor vorzusehen, dem ein mechanisches Differentialgetriebe nachgeschaltet ist.According to one Another advantageous embodiment of the invention the internal combustion engine can be arranged in the vehicle longitudinal direction and the compact gear designed as a compact electrical gear be one coaxial with a drive shaft of the internal combustion engine Generator having electrically in parallel at two right angles connected to the generator electric motors is connected. Analogous to the above-described variant of a hydrostatic compact transmission with mechanical differential gear it is also possible here to provide only a single electric traction motor, which is a mechanical Differential gear is connected downstream.
Besonders bevorzugt ist die Verwendung des erfindungsgemäßen Fahrantriebs in einer mobilen Arbeitsmaschine, insbesondere Gegengewichts-Gabelstapler.Especially preferred is the use of the invention Travel drive in a mobile work machine, especially counterweight forklift.

Alternativ zum beschriebenen Aufbau ist es auch möglich, nur einen Hydromotor vorzusehen und diesem ein mechanisches Differentialgetriebe nachzuschalten. Ferner kann anstelle eines hydrostatischen Kompaktgetriebes auch ein elektrisches Kompaktgetriebe zum Einsatz kommen.alternative to the described structure, it is also possible, only one Provide hydraulic motor and this a mechanical differential gear nachzuschalten. Furthermore, instead of a hydrostatic compact transmission Also an electric compact transmission are used.
