Description
Die Erfindung betrifft ein Hybridantriebsmodul für ein Kraftfahrzeug. Das Hybridantriebsmodul kann integraler Bestandteil eines Kraftfahrzeug-Getriebes sein, oder als eigenständige Einheit mit zumindest einer Schnittstelle zu einem Kraftfahrzeug-Getriebe ausgebildet sein. Die Erfindung betrifft ferner einen Antriebsstrang für ein Kraftfahrzeug mit einem solchen Hybridantriebsmodul.The invention relates to a hybrid drive module for a motor vehicle. The hybrid drive module may be an integral part of a motor vehicle transmission, or be designed as a separate unit with at least one interface to a motor vehicle transmission. The invention further relates to a drive train for a motor vehicle with such a hybrid drive module.
Die Patentanmeldung
Der vorgenannte Aufbau ist aufwändig und führt aufgrund der Vielzahl an verwendeten Nadellagern zu erhöhten Schleppverlusten im Antriebstrang. Es ist daher Aufgabe der Erfindung ein Hybridantriebsmodul bereitzustellen, welches sich durch einen einfacheren und energieeffizienteren Aufbau auszeichnetThe aforementioned structure is complex and leads due to the large number of needle bearings used to increased drag losses in the drive train. It is therefore an object of the invention to provide a hybrid drive module, which is characterized by a simpler and more energy-efficient design
Die Aufgabe wird gelöst durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen, der Beschreibung sowie aus den Figuren.The object is solved by the features of
Erfindungsgemäß wird der im Stand der Technik bekannten Lageraufbau derart modifiziert, dass die Rotornabe über ein Kugellager an der Nabe gelagert ist. Denn Kugellager weisen geringere Reibwerte als Wälzlager mit nadelförmigen Wälzkörpern auf, wodurch die Reibungsverluste des Hybridantriebsmoduls verringert werden. Zudem ist ein Kugellager zur Übertragung von Kräften sowohl in radialer Richtung als auch in axialer Richtung geeignet, wodurch der Aufbau des Hybridantriebsmoduls vereinfacht werden kann.According to the invention, the bearing structure known in the prior art is modified such that the rotor hub is mounted on the hub via a ball bearing. Because ball bearings have lower coefficients of friction than rolling bearings with needle-shaped rolling elements, whereby the friction losses of the hybrid drive module can be reduced. In addition, a ball bearing for transmitting forces in both the radial direction and in the axial direction is suitable, whereby the structure of the hybrid drive module can be simplified.
Vorzugsweise ist zur hydraulischen Betätigung der Kupplung ein Kolben vorgesehen. Der Kolben ist mittels zumindest einer Feder vorgespannt, sodass der Kolben bei inaktiver hydraulischer Betätigung durch die Feder in einer definierten Position gehalten wird. Die Feder kann beispielsweise als Schraubenfeder oder als Tellerfeder ausgebildet sein. Weist der Kolben eine scheiben- oder topfartige Form auf, so können mehrere Schraubenfedern vorgesehen sein, die entlang dem Kolbenumfang verteilt sind. Die Kraft der Feder, bzw. Federn wird vorzugsweise über das Kugellager an der Nabe abgestützt. In anderen Worten befindet sich das Kugellager im Übertragungspfad der axial wirkenden Abstützkraft zwischen der Feder, bzw. Federn und der Nabe.Preferably, a piston is provided for the hydraulic actuation of the clutch. The piston is biased by at least one spring, so that the piston is held in inactive hydraulic actuation by the spring in a defined position. The spring may be formed, for example, as a helical spring or a plate spring. If the piston has a disk-shaped or cup-shaped form, then a plurality of coil springs can be provided, which are distributed along the circumference of the piston. The force of the spring or springs is preferably supported by the ball bearing on the hub. In other words, the ball bearing is in the transmission path of the axially acting support force between the spring and the hub.
Gemäß einer bevorzugten Ausgestaltung weist die hydraulische Betätigung der Kupplung einen Druckausgleichsraum auf. Der Druckausgleichsraum dient zur Kompensation der Druckkräfte im Betätigungsdruckraum der Kupplung, welche durch Rotation des Fluids im Betätigungsdruckraum hervorgerufen werden. Der Druckausgleichsraum wird im Betrieb des Hybridantriebsmodul mit Fluid gefüllt. Der Kolben trennt den Druckausgleichsraum vom Betätigungsdruckraum, sodass die durch die Fliehkraft des Fluids hervorgerufenen Druckkräfte auf beide Seiten des Kolbens wirken. Das Vorsehen eines Druckausgleichsraums für eine hydraulisch betätigte Kupplung ist beispielsweise aus der
Vorzugsweise ist die Stauscheibe unmittelbar am Kugellager abgestützt. In anderen Worten befindet sich kein Element im Kraftübertragungspfad zwischen der Stauscheibe und dem Kugellager, also zum Beispiel keine Einlegscheibe.Preferably, the baffle plate is supported directly on the ball bearing. In other words, there is no element in the power transmission path between the baffle plate and the ball bearing, so for example no washer.
Die Stauscheibe kann zwischen dem Kugellager und einem Absatz der Rotornabe eingespannt sein. Dadurch sind gar keine Befestigungsmittel zur Fixierung der Stauscheibe erforderlich, wodurch der Aufbau des Hybridantriebsmoduls weiter vereinfacht wird.The baffle plate can be clamped between the ball bearing and a shoulder of the rotor hub. As a result, no fastening means for fixing the baffle plate are required, whereby the structure of the hybrid drive module is further simplified.
Gemäß einer bevorzugten Ausgestaltung ist die Stauscheibe an einem Innenring des Kugellagers abgestützt. Der Innenring ist vorzugsweise der Rotornabe zugeordnet, während ein Außenring des Kugellagers der Nabe zugeordnet ist. Innenring und Außenring sind auf geeignete Weise an der Rotornabe, bzw. der Nabe axial gesichert, beispielsweise mittels Sprengringen oder entsprechenden Absätzen.According to a preferred embodiment, the baffle plate is supported on an inner ring of the ball bearing. The inner ring is preferably associated with the rotor hub, while an outer ring of the ball bearing is associated with the hub. Inner ring and Outer ring are axially secured in a suitable manner to the rotor hub, or the hub, for example by means of snap rings or corresponding paragraphs.
Die radiale und axiale Abstützung der Nabe erfolgt vorzugsweise über ein weiteres Kugellager an einem Lagerschild, welches mit dem Gehäuse fest verbunden ist. Derart können die axial und radial wirkenden Kräfte sowohl aus der Lagerung des Rotors und der Nabe sowie aus der axial wirkenden Rückstellkraft der Feder, bzw. der Federn auf einfache Weise am Gehäuse abgestützt werden.The radial and axial support of the hub is preferably via a further ball bearing on a bearing plate, which is fixedly connected to the housing. In this way, the axially and radially acting forces can be supported in a simple manner on the housing both from the bearing of the rotor and the hub and from the axially acting restoring force of the spring or springs.
Der Rotor oder die Rotornabe ist vorzugsweise mit einem Gehäuse eines Drehmomentwandlers drehfest verbunden, sodass der Rotor und das Gehäuse des Drehmomentwandlers um eine gemeinsame Achse rotieren können. Der Drehmomentwandler kann Bestandteil des Hybridantriebsmoduls sein. Das Drehmomentwandlergehäuse ist vorzugsweise über ein zusätzliches Lager an einem zusätzlichen Lagerschild abgestützt. Das zusätzliche Lager kann als Radialnadellager ausgebildet sein, um eine axiale Überbestimmung der Lagerung zu vermeiden.The rotor or the rotor hub is preferably non-rotatably connected to a housing of a torque converter, so that the rotor and the housing of the torque converter can rotate about a common axis. The torque converter may be part of the hybrid drive module. The torque converter housing is preferably supported via an additional bearing on an additional bearing plate. The additional bearing can be designed as a radial needle bearing to avoid an axial overdetermination of storage.
Vorzugsweise ist das Hybridantriebsmodul integraler Bestandteil eines Kraftfahrzeug-Getriebes. Das ein- oder mehrteilige Gehäuse des Hybridantriebsmoduls beherbergt beispielsweise Planetenradsätze und Schaltelemente, mittels denen eine Mehrzahl von Gängen zwischen einer Antriebswelle und einer Abtriebswelle des Getriebes schaltbar sind. Anstelle der Planetenradsätze und Schaltelemente kann das Getriebe auch ein Reibradgetriebe mit verschiebbaren Rädern umfassen, mittels dem das Übersetzungsverhältnis zwischen Antriebswelle und Abtriebswelle stufenlos veränderbar ist. Das Getriebe kann auch als Einfach- oder Doppelkupplungsgetriebe ausgeführt sein, welches schaltbare Stirnradpaare zur Gangbildung nutzt.Preferably, the hybrid drive module is an integral part of a motor vehicle transmission. The one- or multi-part housing of the hybrid drive module houses, for example, planetary gear sets and switching elements by means of which a plurality of gears between a drive shaft and an output shaft of the transmission can be switched. Instead of the planetary gear sets and switching elements, the transmission may also include a friction gear with sliding wheels, by means of which the transmission ratio between the drive shaft and output shaft is continuously variable. The transmission can also be designed as a single or double clutch transmission, which uses switchable spur gear pairs for gear formation.
Alternativ dazu kann das Hybridantriebsmodul als eine eigenständige Einheit mit einer Schnittstelle zu einem Kraftfahrzeug-Getriebe ausgebildet sein. Das Hybridantriebsmodul ist dabei von dem Getriebe lösbar.Alternatively, the hybrid drive module may be configured as an independent unit with an interface to a motor vehicle transmission. The hybrid drive module is detachable from the transmission.
Das Hybridantriebsmodul kann Bestandteil eines Antriebsstrangs eines Kraftfahrzeugs sein. Die elektrische Maschine des Hybridantriebsmoduls kann zum Antrieb des Kraftfahrzeugs und/oder zum Starten eines Verbrennungsmotors des Antriebsstrangs vorgesehen sein.The hybrid drive module may be part of a drive train of a motor vehicle. The electric machine of the hybrid drive module can be provided for driving the motor vehicle and / or for starting an internal combustion engine of the drive train.
