Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Hybridmodul sowie einen damit ausgestatteten Antriebsstrang zur Verfügung zu stellen, die in konstruktiv einfacher Weise eine hohe Lebensdauer gewährleisten.The present invention is based on the object of providing a hybrid module and a drive train equipped therewith which guarantee a long service life in a structurally simple manner.
Die Aufgabe wird durch das erfindungsgemäße Hybridmodul nach Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen des Hybridmoduls sind in den Unteransprüchen 2 und 3 angegeben. Ergänzend wird ein erfindungsgemäßer Antriebsstrang für ein Kraftfahrzeug, welcher das erfindungsgemäße Hybridmodul aufweist, gemäß Anspruch 4 zur Verfügung gestellt.The object is achieved by the hybrid module according to the invention according to
Die Merkmale der Ansprüche können in jeglicher technisch sinnvollen Art und Weise kombiniert werden, wobei hierzu auch die Erläuterungen aus der nachfolgenden Beschreibung sowie Merkmale aus den Figuren hinzugezogen werden können, die ergänzende Ausgestaltungen der Erfindung umfassen.The features of the claims can be combined in any technically meaningful manner, in which case the explanations from the following description and features from the figures, which include supplementary embodiments of the invention, can also be used.
Die Begriffe „axial“ und „radial“ beziehen sich im Rahmen der vorliegenden Erfindung immer auf die Rotationsachse des Hybridmoduls.The terms “axial” and “radial” always relate to the axis of rotation of the hybrid module in the context of the present invention.
Die Erfindung betrifft ein Hybridmodul für einen Antriebsstrang eines Kraftfahrzeugs, insbesondere eines Hybridkraftfahrzeugs, umfassend eine Welle zur zumindest indirekten Kopplung an eine Verbrennungskraftmaschine sowie zur Kopplung an ein Getriebe, sowie umfassend eine elektrische Maschine mit einem Rotor und eine Drehmoment-Begrenzungseinrichtung, wobei der Rotor mit der Welle über die Drehmoment-Begrenzungseinrichtung mechanisch verbunden ist. Insbesondere ist der Rotor unmittelbar mit der Drehmoment-Begrenzungseinrichtung und diese unmittelbar mit der Welle gekoppelt.
Die mechanische Verbindung zwischen Rotor und Welle über die Drehmoment-Begrenzungseinrichtung kann durch eine reibschlüssige Verbindung in der Drehmoment-Begrenzungseinrichtung realisiert sein.
Insbesondere kann dabei vorgesehen sein, keine Kupplungseinrichtung zwischen der elektrischen Maschine und einer Verbrennungskraftmaschine anzuordnen. Das Hybridmodul ist demnach entsprechend einer sogenannten P1-Hybrid-Architektur ausgeführt.
Weiterhin kann die Drehmoment-Begrenzungseinrichtung zur zumindest teilweisen Öffnung eines Drehmoment-Übertragungspfades zwischen Rotor und Welle eingerichtet sein.
Bei Realisierung der mechanischen Verbindung über die Drehmoment-Begrenzungseinrichtung durch eine reibschlüssige Verbindung bedeutet ein zumindest teilweises Öffnen des Drehmoment-Übertragungspfades, so dass die die reibschlüssige Verbindung realisierenden Bauteile ein Durchrutschen aneinander zulassen.The invention relates to a hybrid module for a drive train of a motor vehicle, in particular a hybrid motor vehicle, comprising a shaft for at least indirect coupling to an internal combustion engine and for coupling to a transmission, as well as comprising an electric machine with a rotor and a torque limiting device, the rotor with the shaft is mechanically connected via the torque limiting device. In particular, the rotor is directly coupled to the torque limiting device and this is coupled directly to the shaft.
The mechanical connection between the rotor and the shaft via the torque limiting device can be implemented by a frictional connection in the torque limiting device.
In particular, it can be provided that no coupling device is arranged between the electrical machine and an internal combustion engine. The hybrid module is accordingly designed according to a so-called P1 hybrid architecture.
Furthermore, the torque limiting device can be designed to at least partially open a torque transmission path between the rotor and the shaft.
When the mechanical connection via the torque limiting device is implemented by means of a frictional connection, an at least partial opening of the torque transmission path means that the components implementing the frictional connection allow each other to slip through.
Gemäß einem weiteren Aspekt der Erfindung weist die Welle einen ersten Anschlussbereich zur Kopplung an eine Verbrennungskraftmaschine sowie einen zweiten Anschlussbereich zur Kopplung an ein Getriebe auf.
Das bedeutet, dass die mechanische Verbindung zwischen Welle und Rotor zwischen einem ersten Anschlussbereich und einem zweiten Anschlussbereich der Welle realisiert ist.According to a further aspect of the invention, the shaft has a first connection area for coupling to an internal combustion engine and a second connection area for coupling to a transmission.
This means that the mechanical connection between shaft and rotor is implemented between a first connection area and a second connection area of the shaft.
Gemäß einer weiteren Ausführungsform umfasst das Hybridmodul weiterhin einen Schwingungsdämpfer, der mit der Welle gekoppelt ist und zur mechanischen Kopplung mit der Ausgangswelle einer Verbrennungskraftmaschine eingerichtet ist. Die mechanische Kopplung kann dabei vorzugsweise direkt zwischen dem Schwingungsdämpfer und der Ausgangswelle einer Verbrennungskraftmaschine eingerichtet sein.
Der Schwingungsdämpfer umfasst eine Schwungmasse, Federelemente sowie die Welle, wobei die Schwungmasse einerseits sowie die mit dem Rotor über die Drehmoment-Begrenzungseinrichtung gekoppelte Welle andererseits die zueinander schwingenden Massen eines Zweimassenschwingers darstellen.
Die Schwungmasse kann insbesondere als ein Schwungrad ausgestaltet sein. Insbesondere kann dabei vorgesehen sein, dass die Schwungmasse an einem die Federelemente führenden Bauteil angeordnet und mit diesem fest verbunden ist, oder durch dieses Bauteil selbst ausgebildet ist.According to a further embodiment, the hybrid module further comprises a vibration damper which is coupled to the shaft and is set up for mechanical coupling to the output shaft of an internal combustion engine. The mechanical coupling can preferably be set up directly between the vibration damper and the output shaft of an internal combustion engine.
The vibration damper comprises a flywheel, spring elements and the shaft, the The centrifugal mass on the one hand and the shaft coupled to the rotor via the torque limiting device on the other hand represent the mutually oscillating masses of a two-mass oscillator.
The flywheel can in particular be designed as a flywheel. In particular, it can be provided that the flywheel is arranged on a component guiding the spring elements and firmly connected to it, or is formed by this component itself.
In einer bevorzugten Ausgestaltung des Hybridmoduls kann vorgesehen sein, dass die Drehmoment-Begrenzungseinrichtung radial und axial innerhalb eines von dem Rotor axial und radial begrenzten Raums angeordnet ist.In a preferred embodiment of the hybrid module it can be provided that the torque limiting device is arranged radially and axially within a space that is axially and radially limited by the rotor.
Das erfindungsgemäße Hybridmodul weist den Vorteil auf, dass die mechanische Verbindung zwischen Rotor und Welle durch die Drehmoment-Begrenzungseinrichtung zwecks Schutzes zumindest des Rotors der elektrischen Maschine oder der Welle trennbar ist.
Bei schlagartig in das Hybridmodul eingebrachtem, im Verhältnis zum aktuell über Welle und damit die mechanische Verbindung übertragenem Drehmoment oder von der elektrischen Maschine generiertem Drehmoment, hohem Drehmoment können Schäden an Bauteilen des Hybridmoduls, insbesondere Schäden an Rotor und Welle, insbesondere im Bereich der mechanischen Verbindung, auftreten.
Wirkt ein über eines der beiden Kopplungspartner Rotor und Welle schlagartig auf die mechanische Verbindung übertragenes Drehmoment, so realisiert die Drehmoment-Begrenzungseinrichtung ein zumindest teilweises Öffnen des Drehmoment-Übertragungspfades zwischen Rotor und Welle. Dadurch werden Schäden an den Kopplungspartnern oder der mechanischen Verbindung vermieden.
Überhöhte Drehmomente können dabei insbesondere von einem an das Hybridmodul angeschlossenen Nebenantrieb oder auch von einem Bremsassistent-System beim Durchführen einer Gefahrenbremsung aufgebracht werden. Vorteilhafterweise ist es daher zudem möglich, aufgrund der Sicherheit durch die Drehmoment-Begrenzungseinrichtung die Welle oder den Rotor, zumindest im Bereich der mechanischen Verbindung, mit geringerem Materialeinsatz und/oder Fertigungsaufwand und damit kostengünstiger auszugestalten.
Die Drehmoment-Begrenzungseinrichtung schützt außerdem weitere, mit der Welle verbundene Bauteile, wie z.B. den Schwingungsdämpfer oder eine Eingangsseite eines Getriebes, vor einer von der elektrischen Maschine ausgehenden Überlast.The hybrid module according to the invention has the advantage that the mechanical connection between rotor and shaft can be separated by the torque limiting device for the purpose of protecting at least the rotor of the electrical machine or the shaft.
In the event of high torque suddenly introduced into the hybrid module in relation to the torque currently transmitted via the shaft and thus the mechanical connection or the torque generated by the electrical machine, damage to components of the hybrid module, in particular damage to the rotor and shaft, especially in the area of the mechanical connection , occur.
If a torque that is suddenly transmitted to the mechanical connection via one of the two coupling partners rotor and shaft acts, the torque limiting device implements at least partial opening of the torque transmission path between rotor and shaft. This prevents damage to the coupling partners or the mechanical connection.
Excessive torques can in particular be applied by a power take-off connected to the hybrid module or also by a brake assist system when performing emergency braking. It is therefore advantageously also possible, due to the safety provided by the torque limiting device, to design the shaft or the rotor, at least in the area of the mechanical connection, with less material input and / or manufacturing costs and thus more cost-effectively.
The torque limiting device also protects other components connected to the shaft, such as the vibration damper or an input side of a gearbox, from an overload emanating from the electrical machine.
Des Weiteren wird erfindungsgemäß ein Antriebsstrang für ein Kraftfahrzeug zur Verfügung gestellt, der ein erfindungsgemäßes Hybridmodul, eine Verbrennungskraftmaschine und ein Getriebe aufweist, wobei die Verbrennungskraftmaschine und das Getriebe mit der Welle des Hybridmoduls mechanisch gekoppelt sind.
Die hier genannten mechanischen Kopplungen sind bis auf die Drehmoment-Übertragungseinrichtung vorzugsweise derart ausgestaltet, dass mit ihnen drehfest ein Drehmoment übertragbar ist.Furthermore, according to the invention, a drive train for a motor vehicle is provided which has a hybrid module according to the invention, an internal combustion engine and a transmission, the internal combustion engine and the transmission being mechanically coupled to the shaft of the hybrid module.
With the exception of the torque transmission device, the mechanical couplings mentioned here are preferably designed such that a torque can be transmitted with them in a rotationally fixed manner.
