Description
Die Erfindung betrifft einen CVT-Antriebsstrang für ein Hybrid-Fahrzeug mit einem stufenlos verstellbaren Getriebe (engl. continuosly variable transmission - CVT), das einen eingangsseitigen Scheibensatz und einen ausgangsseitigen Scheibensatz umfasst, einem ersten Antrieb, der eine Verbrennungskraftmaschine umfasst und mit dem eingangsseitigen Scheibensatz unter Einsatz einer Kupplung koppelbar ist, und einem zweiten Antrieb, der eine erste Elektromaschine umfasst und dauerhaft oder situationsbedingt drehfest mit dem ausgangsseitigen Scheibensatz verbunden ist.The invention relates to a CVT drive train for a hybrid vehicle with a continuously variable transmission (English: continuously variable transmission - CVT), which comprises an input-side disc set and an output-side disc set, a first drive, which comprises an internal combustion engine, and with the input-side disc set can be coupled using a clutch, and a second drive, which comprises a first electric machine and is connected permanently or as a result of the situation in a rotationally fixed manner to the set of disks on the output side.
Aus dem Stand der Technik sind bereits Antriebsstränge für Hybrid-Fahrzeuge mit stufenlos verstellbaren Getrieben bekannt. Beispielsweise offenbart die
Auch offenbart ein anderes Dokument, etwa die
Der vorstehend beschriebene Stand der Technik hat jedoch den Nachteil, dass zusätzliche Planetenstufen für eine Rückwärtsfahrt und/oder zur Drehmomentwandlung eine verhältnismäßig geringe Systemeffizienz aufweisen und zusätzlichen Platz beanspruchen. Ist die Rückwärtsfahrt bei dem Hybrid-Fahrzeug nur in einem elektrischen Fahrmodus möglich, so kann es auch vorkommen, dass durch plötzliches Entladen der Batterie keine Energie zum Antreiben des Elektromotors vorliegt.However, the prior art described above has the disadvantage that additional planetary stages for backward travel and / or for torque conversion have a relatively low system efficiency and take up additional space. If the hybrid vehicle is only able to drive backwards in an electric driving mode, it can also happen that there is no energy for driving the electric motor due to the sudden discharge of the battery.
Es ist also die Aufgabe der Erfindung, die Nachteile aus dem Stand der Technik zu vermeiden oder wenigstens zu mildern. Insbesondere soll ein CVT-Hybridstrang für ein Hybrid-Fahrzeug in kompakter und platzsparender Bauweise mit hoher Systemeffizienz bereitgestellt werden, welches ein Vorwärts- und Rückwärtsfahren des Hybrid-Fahrzeugs unabhängig von einem Ladezustand (engl. state of charge - SoC) einer Batterie ermöglicht.It is therefore the object of the invention to avoid or at least alleviate the disadvantages of the prior art. In particular, a CVT hybrid train for a hybrid vehicle is to be provided in a compact and space-saving design with high system efficiency, which enables the hybrid vehicle to be driven forwards and backwards independently of a state of charge (SoC) of a battery.
Mit anderen Worten, es ist die Aufgabe der Erfindung, einen CVT-Hybridstrang für ein Hybrid-Fahrzeug bereitzustellen, welcher keine zusätzliche Planetenstufe für die Rückwärtsfahrt und keinen zusätzlichen Drehmomentwandler zur Vibrationsreduktion beim Starten der Verbrennungskraftmaschine benötigt und somit eine hohe Systemeffizienz aufweist.In other words, it is the object of the invention to provide a CVT hybrid train for a hybrid vehicle which does not require an additional planetary stage for reversing and no additional torque converter for vibration reduction when starting the internal combustion engine and thus has a high system efficiency.
Diese Aufgabe wird bei einem gattungsgemäßen CVT-Antriebsstrang erfindungsgemäß dadurch gelöst, dass ein zusätzlicher dritter Antrieb, der eine zweite Elektromaschine umfasst, dauerhaft oder situationsbedingt drehfest mit dem ersten Antrieb verbunden ist.In the case of a generic CVT drive train, this object is achieved according to the invention in that an additional third drive, which comprises a second electric machine, is connected to the first drive in a rotationally fixed or permanent manner.
Dies hat den Vorteil, dass das Hybrid-Fahrzeug bei der Rückwärtsfahrt lediglich durch den zweiten Antrieb angetrieben wird, somit keine zusätzliche Planetenstufe benötigt wird und die Abmaße des CVT-Antriebsstrangs optimiert werden können. Auch für den Fall, dass die Batterie bei der Rückwärtsfahrt keine Energie für den zweiten Antrieb bereitstellen kann, hat der erfindungsgemäße CVT-Antriebsstrang den Vorteil, dass der erste Antrieb im rein elektrischen Betrieb unabhängig von dem zweiten Antrieb den dritten Antrieb antreiben kann, so dass dieser als Generator arbeitet. Des Weiteren können beim Start des ersten Antriebs entstehende Vibrationen durch ein anfängliches Antreiben des ersten Antriebs durch den dritten Antrieb gemindert werden.This has the advantage that the hybrid vehicle is only driven by the second drive when reversing, so that no additional planetary stage is required and the dimensions of the CVT drive train can be optimized. Even in the event that the battery cannot provide energy for the second drive when reversing, the CVT drive train according to the invention has the advantage that the first drive can drive the third drive in purely electrical operation independently of the second drive, so that this works as a generator. Furthermore, vibrations occurring at the start of the first drive can be reduced by initially driving the first drive by the third drive.
Vorteilhafte Ausführungsformen sind in den Unteransprüchen beansprucht und werden nachfolgend näher erläutert.Advantageous embodiments are claimed in the subclaims and are explained in more detail below.
Dabei kann das mit dem erfindungsgemäßen CVT-Antriebsstrang ausgestattete Hybrid-Fahrzeug in einem ersten Lademodus lediglich durch den zweiten Antrieb angetrieben werden, so dass das Hybrid-Fahrzeug in einem rein elektrischen Fahrmodus betrieben wird und somit die Abgasemissionen im Wesentlichen unterdrückt werden könnenIn this case, the hybrid vehicle equipped with the CVT drive train according to the invention can be driven in a first charging mode only by the second drive, so that the hybrid vehicle is operated in a purely electric driving mode and the exhaust gas emissions can thus be substantially suppressed
Des Weiteren kann bei dem mit dem erfindungsgemäßen CVT-Antriebsstrang ausgestattete Hybrid-Fahrzeug der erste Antrieb in dem ersten Lademodus unabhängig von dem zweiten Antrieb den dritten Antrieb antreiben, so dass dieser als Generator arbeitet. Das hat den Vorteil, dass der erste Antrieb bei dessen optimalen Lastpunkt betrieben werden kann und dadurch bei möglichst geringen Abgasemissionen zusätzliche elektrische Leistung erzeugt werden kann.Furthermore, in the hybrid vehicle equipped with the CVT drive train according to the invention, the first drive in the first charging mode can drive the third drive independently of the second drive, so that it works as a generator. This has the advantage that the first drive can be operated at its optimum load point and additional electrical power can be generated with the lowest possible exhaust gas emissions.
Erfindungsgemäß kann der CVT-Antriebsstrang ferner eine Getriebeausgangswelle, welche mit dem ausgangsseitigen Scheibensatz drehfest verbunden ist, aufweisen. Dabei kann der zweite Antrieb koaxial zu der Getriebeausgangswelle angeordnet sein, wodurch der Platzbedarf und die Abmessungen des CVT-Antriebsstrangs minimiert werden können.According to the invention, the CVT drive train can furthermore have a transmission output shaft which is connected in a rotationally fixed manner to the set of disks on the output side. The second drive can be coaxial with the transmission output shaft be arranged, whereby the space requirement and the dimensions of the CVT drive train can be minimized.
