Description
Die Erfindung betrifft einen Starter-Generator eines Kraftfahrzeugs mit einer elektrischen Maschine mit den im Oberbegriff des Anspruchs 1 genannten Merkmalen.The The invention relates to a starter-generator of a motor vehicle with an electric machine with those in the preamble of the claim 1 mentioned features.
Stand der TechnikState of the art
Ein
Starter-Generator eines Kraftfahrzeugs der eingangs genannten Art
ist aus der deutschen Offenlegungsschrift
Das flachzylindrische Gehäuse übernimmt die Funktion eines Zwischengehäuses, welches einerseits an der Brennkraftmaschine und andererseits an dem Getriebe befestigbar ist. Das Zwischengehäuse vergrößert dadurch allerdings nicht nur die Abmessungen des Starter-Generators, sondern bewirkt zudem eine Erhöhung des axial verlaufenden Bauvolumens einer Gesamtanordnung umfassend den Starter-Generator und daran ankoppelbarer Komponenten, wie Brennkraftmaschine und/oder Getriebe. Eine derartige Veränderung der axialen Baugröße ist nicht nur unerwünscht, sondern steht einem allgemeinen Trend, hin zu einer kompakten Bauweise, entgegen. Ein Zwischengehäuse der vorgenannten Art bedingt zudem einen erhöhten Montageaufwand sowie einen zusätzlichen Materialeinsatz und kann die so genannte Toleranzkette der Gesamtanordnung negativ beeinflussen.The flat cylindrical housing takes over the function an intermediate housing, which on the one hand to the internal combustion engine and on the other hand attachable to the transmission. The intermediate housing However, this not only increases the dimensions of the starter-generator, but also causes an increase comprising the axially extending volume of an overall arrangement the starter-generator and components that can be coupled to it, such as internal combustion engine and / or gear. Such a change of the axial Frame size is not only undesirable, but is contrary to a general trend towards a compact design. An intermediate housing of the aforementioned type also requires an increased installation effort and an additional Material use and can the so-called tolerance chain of the overall arrangement influence negatively.
Offenbarung der ErfindungDisclosure of the invention
Der erfindungsgemäße Starter-Generator eines Kraftfahrzeugs mit den im Anspruch 1 genannten Merkmalen bietet demgegenüber den Vorteil, dass eine platzsparende Baueinheit gegeben ist, die mit einer geringeren Anzahl an Bauteilen auskommt. Insbesondere wird das gemäß dem eingangs erwähnten Stand der Technik beschriebene flachzylindrische Gehäuse entbehrlich. Die elektrische Maschine ist dabei mit zumindest einem Mittel zur Lagerung an einem Gehäuseteil des Getriebes versehen. Bei an dem Gehäuseteil angekoppelter elektrischer Maschine entspricht dies einer Integration der Eigenlagerung der elektrischen Maschine in dem Gehäuseteil. Hierzu wird ein verfügbarer Raum des Gehäuseteils dazu genutzt, eine Lagerstelle für die elektrische Maschine so anzuordnen, dass insgesamt an axialer Baulänge gewonnen wird. Ferner werden durch einen Rotor bedingte, an der Elektromaschine auftretende dynamische Kräfte von dem Lager der Eigenlagerung aufgenommen und in das Gehäuseteil des Getriebes geleitet, wodurch ein Festlager für den Rotor gegeben ist.Of the Inventive starter generator of a motor vehicle with the features mentioned in claim 1 offers the other hand the advantage that a space-saving unit is given, the works with a smaller number of components. Especially This will be according to the above-mentioned state The technique described flat cylindrical housing dispensable. The electric machine is provided with at least one means for Storage provided on a housing part of the transmission. at on the housing part coupled electrical machine this corresponds to an integration of the internal storage of the electrical Machine in the housing part. This will be an available Room of the housing part used to a storage place for to arrange the electric machine so that the total axial length is won. Furthermore, due to a rotor, on the Electric machine occurring dynamic forces of the bearing received the self-storage and in the housing part of the transmission passed, whereby a bearing for the rotor is given.
Auf Grund der reduzierten Baulänge der elektrischen Maschine verkürzt sich demnach auch die Länge der Gesamtanordnung umfassend die elektrische Maschine, die Brennkraftmaschine, das Getriebe und gegebenenfalls dazwischen angeordneter Kupplungseinheiten. Hierbei ist die elektrische Maschine als zentrale Baueinheit in einer unmittelbaren Anordnung einerseits an dem Gehäuseteil des Getriebes und andererseits an der Brennkraftmaschine vorgesehen. Dadurch ist es möglich, verschiedene Kupplungsarten und Kupplungsausführungen mit unterschiedlichen Abmessungen, insbesondere hinsichtlich der jeweiligen axialen Baulänge, einzusetzen. Eine größere Vielfalt der Kupplungsarten erlaubt eine Umsetzung verschiedener Applikationen und damit letztlich eine umfangreichere Palette an Einsatzmöglichkeiten im Fahrzeugbau. Hervorzuheben ist bei diesem Sachverhalt, dass lediglich der Bauraum einer fremdgelagerten elektrischen Maschine benötigt wird, um mit der elektrischen Maschine des Starter-Generators die Betriebseigenschaften der Eigenlagerung zu erzielen.On Reason for the reduced length of the electrical machine Accordingly, the length of the overall arrangement is shortened comprising the electric machine, the internal combustion engine, the transmission and optionally arranged therebetween coupling units. in this connection is the electric machine as a central unit in an immediate Arrangement on the one hand on the housing part of the transmission and on the other hand provided on the internal combustion engine. That's it possible, different types of couplings and couplings with different dimensions, especially in terms of respective axial length, use. A bigger one Diversity of coupling types allows a variety of different Applications and ultimately a wider range Possible uses in vehicle construction. To emphasize is in this situation, that only the space of a foreign stored Electric machine is needed to with the electric Engine of the starter-generator the operating characteristics of the self-storage to achieve.
Vorteilhafte Weiterbildungen ergeben sich durch die Merkmale der abhängigen Ansprüche.advantageous Further developments result from the characteristics of the dependent Claims.
In einer vorteilhaften Weiterbildung der Erfindung ist es vorgesehen, dass das Mittel zur Lagerung der elektrischen Maschine als Loslager ausgeführt ist. Das an einer Welle angeordnete Loslager lässt hierbei eine Bewegung in Längsrichtung der Welle zu, um eine durch Temperaturschwankungen bedingte Wärmedehnung oder auch Kälteschrumpfung an der Lagerung angeordneter Bauteile ausgleichen zu können.In An advantageous development of the invention is provided that the means for supporting the electric machine as a floating bearing is executed. The arranged on a shaft floating bearing this leaves a movement in the longitudinal direction of Wave to, due to thermal fluctuations caused by thermal expansion or cold shrinkage arranged on the storage To be able to compensate components.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist es vorgesehen, dass die elektrische Maschine an einem eigenen Gehäuseabschnitt zusätzlich lagerbar ist. Betrachtet man eine Komponentenanordnung mit der elektrischen Maschine in Verbindung mit dem Gehäuseteil des Getriebes, so ergibt sich durch die Kombination der grundlegenden Lagerung der elektrischen Maschine an dem Gehäuseteil und der zusätzlichen Lagerung an dem eigenen Gehäuseabschnitt eine Doppellagerung. Eine derartige Doppellagerung kommt zum einen einer Integration der Eigenlagerung in dem Gehäuseteil und zudem einer Eigenlagerung in dem Gehäuseabschnitt gleich. Dadurch ist es möglich, gegebenenfalls vorkommende Verkippungen der elektrischen Maschine des Starter-Generators an einer Rotornabe zu minimieren. Verringerte Verkippungen sind gleichbedeutend mit einer wesentlich verbesserten Exzentrität der elektrischen Maschine. Die elektrische Maschine ist hierbei statisch bestimmt. Auf Grund der verringerten Verkippungen und einer damit einhergehenden Stabilisierung der elektrischen Maschine ist ein kleinerer nominaler Luftspalt zwischen einem Stator und einem Rotor der Elektromaschine realisierbar. Ein kleiner Luftspalt bewirkt bei gleichbleibendem Bauraum der elektrischen Maschine eine höhere konstante Leistung mit einem höheren Wirkungsgrad derselben. Darüber hinaus werden bei einer derartigen Anordnung mit einer Doppellagerung die dynamischen Kräfte des Rotors von beiden Lagern der Eigenlagerung aufgenommen und in den Gehäuseteil des Getriebes geleitet. Dies stellt eine Kombination aus dem Festlager mit Loslager dar.According to a preferred embodiment of the invention, it is provided that the electric machine is additionally storable on a separate housing section. If one considers a component arrangement with the electric machine in conjunction with the housing part of the transmission, the result is a combination of the basic mounting of the electric machine on the housing part and the additional bearing on the own housing section of a double bearing. Such a double bearing is on the one hand an integration of the internal storage in the housing part and also a self-storage in the housing section equal. This makes it possible to minimize any occurring tilting of the electric machine of the starter-generator on a rotor hub. Reduced tilts are equal tend with a much improved eccentricity of the electric machine. The electric machine is determined statically. Due to the reduced tilting and a concomitant stabilization of the electric machine, a smaller nominal air gap between a stator and a rotor of the electric machine can be realized. A small air gap causes the same installation space of the electric machine, a higher constant power with a higher efficiency of the same. Moreover, in such an arrangement with a double bearing, the dynamic forces of the rotor are absorbed by both bearings of the integral bearing and directed into the housing part of the transmission. This represents a combination of the fixed bearing with floating bearing.
Nach einer vorteilhaften Ausgestaltung der Erfindung ist es vorgesehen, dass der Gehäuseabschnitt der elektrischen Maschine als Lagerschild ausgeführt ist.To An advantageous embodiment of the invention is provided that the housing portion of the electric machine as End shield is executed.
Ein derartiges, insbesondere deckelförmiges, Lagerschild dient zur Kapselung eines Maschinengehäuses der Elektromaschine. Gegebenenfalls kann dem Lagerschild ein gegenüberliegendes weiteres Lagerschild zugeordnet sein. Das Lagerschild schützt die Elektromaschine zum einen vor Fremdeinwirkungen und dient zum anderen insbesondere zur Lagerung einer Rotorwelle. Eine präzise Einpassung in dem Gehäuseabschnitt, insbesondere Statorgehäuse, sorgt für einen möglichst gleichmäßigen Luftspalt zwischen dem Stator und dem Rotor.One such, in particular cover-shaped, bearing plate is used for encapsulating a machine housing of the electric machine. Optionally, the bearing plate opposite one be assigned to another end shield. The end shield protects the electric machine on the one hand before external influences and serves for other in particular for the storage of a rotor shaft. A precise Fitting in the housing section, in particular stator housing, ensures a uniform air gap between the stator and the rotor.
In einer bevorzugten Ausführungsvariante der Erfindung ist es vorgesehen, dass die elektrische Maschine an dem Gehäuseabschnitt mittels eines Festlagers gelagert ist. Das Festlager fixiert die elektrische Maschine in allen drei Translations-Freiheitsgraden und gewährleistet dadurch eine präzise Rotorführung sowie eine zuverlässige Wirkverbindung zu angrenzenden Baueinheiten, wie Getriebe und Brennkraftmaschine.In a preferred embodiment of the invention it is provided that the electric machine on the housing section is stored by means of a fixed bearing. The fixed bearing fixes the electric machine in all three degrees of translational freedom and thereby ensures precise rotor guidance and a reliable operative connection to adjacent ones Building units, such as transmission and internal combustion engine.
In einem vorteilhaften Ausführungsbeispiel der Erfindung ist das Festlager kraftschlüssig, formschlüssig oder stoffschlüssig mit dem Gehäuseabschnitt verbunden, so dass je nach Anwendung und Einsatzgebiet die jeweils günstigste Verbindungsart auswählbar ist.In an advantageous embodiment of the invention the fixed bearing non-positively, positively or cohesively connected to the housing section, so that depending on the application and field of application, the most favorable Connection type is selectable.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist es vorgesehen, dass wenigstens eines der beiden Lager mit Kugellagern, insbesondere Rillenkugellagern, versehen ist. Kugellager zählen zu der Kategorie der Wälzlager, die zwei zueinander bewegliche Komponenten, nämlich den so genannten Innenring und den so genannten Außenring, aufweisen. Der Innenring ist hierbei von dem Außenring durch Wälzkörper, insbesondere Kugeln, getrennt. Zwischen den drei Hauptkomponenten Innenring, Außenring und Wälzkörper tritt hauptsächlich Rollreibung auf. Da die Wälzkörper im Innen- und Außenring auf gehärteten Stahlflächen mit optimierter Schmierung abrollen, ist die Rollreibung derartiger Lager relativ gering.According to one advantageous development of the invention, it is provided that at least one of the two bearings with ball bearings, in particular Deep groove ball bearings, is provided. Ball bearings are among the Category of rolling bearings, the two mutually movable Components, namely the so-called inner ring and the so-called outer ring. The inner ring is here from the outer ring by rolling elements, in particular Balls, isolated. Between the three main components inner ring, outer ring and rolling elements occurs mainly rolling friction on. Since the rolling elements in the inner and outer ring on hardened steel surfaces with optimized lubrication unroll, the rolling friction of such bearings is relatively low.
In einer vorteilhaften Weiterbildung der Erfindung ist eine Anordnung mit einem Starter-Generator und mit einem Gehäuseteil des Getriebes vorgesehen, bei der das Gehäuseteil als Getriebedeckel ausgeführt ist. Der Getriebedeckel ist in besonderem Maße für eine Einbindung des Mittels zur Lagerung der elektrischen Maschine geeignet, da es sich dabei um eine Baueinheit handelt, die bei der Gesamtanordnung umfassend das Getriebe, die Brennkraftmaschine und die Elektromaschine der letztgenannten Komponente baulich am nächsten kommt. Gemäß einer bevorzugten Ausführungsform der Erfindung ist eine Anordnung vorgesehen, bei der die elektrische Maschine innerhalb des Gehäuseteils, insbesondere innerhalb des Getriebedeckels, gelagert ist. Das Gehäuseteil beziehungsweise der Getriebedeckel dient dabei als Aufnahmeraum für den die elektrische Maschine aufweisenden Starter-Generator. Dabei ist gerade die Lagerung mit zumindest einer Lagerstelle innerhalb des Gehäuseteils platziert, wodurch sich eine erhebliche Einsparung an Bauraum ergibt.In An advantageous development of the invention is an arrangement with a starter generator and with a housing part of the Gear provided, in which the housing part as a gear cover is executed. The gear cover is in particular for an integration of the means for storing the electrical machine suitable, since it is a structural unit, which in the Overall arrangement comprising the transmission, the internal combustion engine and the electric machine of the latter component structurally closest comes. According to a preferred embodiment The invention provides an arrangement in which the electric machine within the housing part, in particular within the Gear cover, is stored. The housing part or The gear cover serves as a receiving space for the the electric machine having starter generator. It is just the storage with at least one storage location within the Housing part placed, resulting in a significant saving results in space.
Besonders vorteilhaft ist der Einsatz eines vorgenannten Starter-Generators beziehungsweise einer vorgenannten Anordnung an einem Kraftfahrzeug, da in diesem Technologiesektor eine kompakte, Bauraum sparende und mit geringen Toleranzen in puncto Lagerung, Verkippung, Luftspalt und Exzentrität versehene Antriebseinheit gewünscht ist.Especially advantageous is the use of an aforementioned starter generator or an aforementioned arrangement on a motor vehicle, because in this technology sector a compact, space-saving and with low tolerances in terms of storage, tilting, air gap and eccentric drive unit desired is.
