Abstract
Description
Die Erfindung bezieht sich auf eine Startvorrichtung für eine Brennkraftmaschine nach dem Oberbegriff des Anspruches 1.The invention relates to a starting device for an internal combustion engine according to the preamble of claim 1.
Bekannt sind Startvorrichtungen für Brennkraftmaschinen, beispielsweise aus der
Die Getriebebauteile wie z.B. ein Hohlrad des Planetengetriebes unterliegen im Betrieb stoßartigen Drehmomentbelastungen. Zur Reduzierung der Belastung ist gemäß der
Der Erfindung liegt die Aufgabe zu Grunde, mit einfachen konstruktiven Maßnahmen die mechanische Belastung im Antriebsstrang einer Startvorrichtung für eine Brennkraftmaschine zu reduzieren.The invention is based on the object to reduce the mechanical load in the drive train of a starting device for an internal combustion engine with simple constructive measures.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen der unabhängigen Ansprüche gelöst. Die Unteransprüche geben zweckmäßige Weiterbildungen an.This object is achieved with the features of the independent claims. The dependent claims indicate expedient developments.
Die erfindungsgemäße Startvorrichtung, welche zum Starten von Brennkraftmaschinen eingesetzt wird, weist ein Starterritzel auf, das zwischen einer zurückgezogenen Außerfunktionsstellung und einer vorgespurten Eingriffsposition mit einem Zahnkranz der Brennkraftmaschine verstellbar ist. Die Verstellbewegung des Starterritzels wird vorteilhafterweise mittels eines Starterrelais, insbesondere eines elektromagnetischen Starterrelais durchgeführt, dessen Hubankerbewegung über ein Übertragungsbauteil, beispielsweise einen Gabelhebel, direkt oder indirekt auf das Starterritzel übertragbar ist. Bei der Verstellbewegung des Starterritzels zwischen der Außerfunktions- und der Eingriffsposition handelt es sich vorzugsweise um eine axiale Stellbewegung.The starting device according to the invention, which is used for starting internal combustion engines, has a starter pinion which is adjustable between a retracted non-functional position and a pre-loaded engagement position with a ring gear of the internal combustion engine. The adjusting movement of the starter pinion is advantageously carried out by means of a starter relay, in particular an electromagnetic starter relay whose lifting armature movement can be transmitted directly or indirectly to the starter pinion via a transmission component, for example a fork lever. The adjusting movement of the starter pinion between the non-functional and the engaged position is preferably an axial adjusting movement.
Die Drehbewegung des Starterritzels wird über einen elektrischen Startermotor erzeugt, dem zur Drehzahluntersetzung ein Getriebe nachgeschaltet ist, welches ausgangsseitig mit dem Starterritzel verbunden ist. Ein Getriebebauteil ist an beiden axialen Stirnseiten über Dämpfungselemente in Umfangsrichtung gegenüber benachbarten Bauteilen des Getriebes bzw. des Startermotors abgestützt. Das betreffende Getriebebauteil nimmt bei einer Rotationsbewegung des Startermotors Drehmomente auf, die über die Dämpfungselemente an den sich anschließenden Bauteilen abgestützt werden. Die Dämpfungselemente befinden sich an beiden axialen Stirnseiten und liegen unmittelbar an der jeweiligen Stirnseite des Getriebebauteils an, so dass in Umfangs- bzw. Drehrichtung das Getriebebauteil vollständig über die Dämpfungselemente abgestützt ist und dementsprechend in Umfangsrichtung eine Dämpfung bzw. Kappung von Drehmomentspitzen erfolgt, so dass auch die angrenzenden Bauteile, welche das Drehmoment aufnehmen, einer entsprechend geringeren Belastung unterliegen.The rotational movement of the starter pinion is generated by an electric starter motor, which is followed by a gear for speed reduction, which is the output side connected to the starter pinion. A transmission component is supported on both axial end faces via damping elements in the circumferential direction relative to adjacent components of the transmission or of the starter motor. The relevant transmission component receives during a rotational movement of the starter motor torques which are supported via the damping elements on the adjoining components. The damping elements are located on both axial end faces and lie directly against the respective end face of the transmission component, so that the transmission component is fully supported in the circumferential or rotational direction via the damping elements and accordingly takes place in the circumferential direction damping or capping of torque peaks, so that also the adjacent components, which absorb the torque, are subject to a correspondingly lower load.
Ein weiterer Aspekt der Erfindung bezieht sich ebenfalls auf eine Startvorrichtung mit einem elektromotorisch angetriebenen Starterritzel, welches zwischen einer Außerfunktionsposition und einer Eingriffsposition mit einem Zahnkranz der Brennkraftmaschine verstellbar ist. Dem elektrischen Startermotor ist ein Getriebe zur Drehzahluntersetzung nachgeschaltet, wobei mindestens ein Dämpfungselement an zumindest einer axialen Stirnseite eines Getriebebauteils angeordnet ist. Das Dämpfungselement stützt sich zumindest in Umfangsrichtung an dem axial angrenzenden Polgehäuse des elektrischen Startermotors ab. Das Polgehäuse nimmt somit Momente in Dreh- bzw. Umfangsrichtung auf, wobei Drehmomentspitzen auf Grund der Lagerung in Umfangsrichtung über das bzw. die Dämpfungselemente reduziert sind.Another aspect of the invention also relates to a starting device with an electric motor driven starter pinion, which is adjustable between a non-functional position and an engagement position with a ring gear of the internal combustion engine. The electric starter motor is followed by a transmission for speed reduction, wherein at least one Damping element is arranged on at least one axial end side of a transmission component. The damping element is supported at least in the circumferential direction on the axially adjacent pole housing of the electric starter motor. The pole housing thus absorbs moments in the rotational or circumferential direction, wherein torque peaks are reduced due to the storage in the circumferential direction over the or the damping elements.
Gemäß einer vorteilhaften Ausführung ist vorgesehen, dass das Getriebebauteil über die an beiden axialen Stirnseiten angeordneten Dämpfungselemente auch in Achsrichtung an den angrenzenden Bauteilen abgestützt ist. Hierdurch wird in Achsrichtung und in Umfangs- bzw. Drehrichtung eine schwimmende Lagerung des Getriebebauteils erreicht.According to an advantageous embodiment, it is provided that the transmission component is supported via the arranged on both axial end faces damping elements in the axial direction of the adjacent components. As a result, a floating mounting of the transmission component is achieved in the axial direction and in the circumferential or rotational direction.
Gemäß einer weiteren zweckmäßigen Ausführung sind an mindestens einer Stirnseite des Getriebebauteils, vorzugsweise jedoch an beiden Stirnseiten des Getriebebauteils über den Umfang verteilt mehrere Dämpfungselemente angeordnet. Die Dämpfungselemente an den gegenüberliegenden Stirnseiten können entweder gleich aufgebaut sein oder sich in einem Parameter unterscheiden, beispielsweise im Hinblick auf die Größe, die Geometrie und/oder die Dämpfung. Die Dämpfungselemente bestehen vorzugsweise aus einem Elastomer und sind beispielsweise als Elastomerblock ausgeführt. Um im Soll-bzw. Normzustand einen direkten Kontakt zwischen dem Getriebebauteil und angrenzenden weiteren Bauteilen des Startermotors bzw. des Getriebes zu vermeiden, wird das Getriebebauteil zweckmäßigerweise bezogen auf den zur Verfügung stehenden Einbauraum geringfügig kleiner dimensioniert, so dass die Abstützung ausschließlich über Dämpfungselemente gewährleistet ist.According to a further expedient embodiment, a plurality of damping elements are arranged on at least one end face of the transmission component, but preferably on both end faces of the transmission component distributed over the circumference. The damping elements on the opposite end faces can either have the same structure or differ in one parameter, for example with regard to the size, the geometry and / or the damping. The damping elements are preferably made of an elastomer and are designed for example as an elastomer block. In the nominal or. Standard state to avoid direct contact between the transmission component and adjacent other components of the starter motor or the transmission, the transmission component is expediently dimensioned slightly smaller relative to the available installation space, so that the support is ensured exclusively by damping elements.
Für die Dämpfung in Dreh- bzw. Umfangsrichtung kann es zweckmäßig sein, an mindestens einer Stirnseite des Getriebebauteils ein oder mehrere axial überstehende Stützglieder anzuordnen, an dem sich zumindest ein Dämpfungselement in Umfangsrichtung abstützt. Vorteilhafterweise sind an beiden Stirnseiten des Getriebebauteils derartige axial überstehende Stützglieder angeordnet. Bei einer Drehmomentbeaufschlagung versucht sich das Getriebebauteil zu verdrehen; die hierbei auftretenden Momente werden über die axialen Stützglieder auf die Dämpfungselemente und von diesen weiter auf die benachbarten Bauteile übertragen.For the damping in rotational or circumferential direction, it may be appropriate to arrange on at least one end face of the transmission component one or more axially projecting support members on which at least one damping element is supported in the circumferential direction. Advantageously, such axially projecting support members are arranged on both end faces of the transmission component. When a torque is applied, the transmission component tries to twist; the moments occurring in this case are transmitted via the axial support members on the damping elements and of these further to the adjacent components.
Die Dämpfungselemente können sich an einer Seite des Getriebebauteils auf einer Motorlagerplatte abstützen, die sich ihrerseits an dem Polgehäuse des Startermotors abstützt. Die Motorlagerplatte kann fest mit dem Polgehäuse verbunden sein, jedoch als separates Bauteil ausgebildet sein.The damping elements can be supported on one side of the transmission component on a motor bearing plate, which in turn is supported on the pole housing of the starter motor. The engine mount plate can be firmly connected to the pole housing, but be designed as a separate component.
Auf der der Motorplatte gegenüberliegenden Seite befindet sich zweckmäßig ein Zwischenlagerteil, welches ebenfalls ein Bauteil des Getriebes darstellt. An dem Zwischenlagerteil stützen sich die zugewandten Dämpfungselemente des Getriebebauteils in Umfangsrichtung und ggf. in Achsrichtung ab. Das Zwischenlagerteil kann mit dem Polgehäuse des elektrischen Startermotors verbunden sein, insbesondere derart, dass das Zwischenlagerteil im Polgehäuse zentriert ist und somit die Drehlage des Zwischenlagerteils am Polgehäuse ausgerichtet ist.On the opposite side of the motor plate is expediently an intermediate bearing part, which also represents a component of the transmission. At the intermediate bearing part, the facing damping elements of the transmission component are supported in the circumferential direction and optionally in the axial direction. The intermediate bearing part can be connected to the pole housing of the electric starter motor, in particular such that the intermediate bearing part is centered in the pole housing and thus the rotational position of the intermediate bearing part is aligned on the pole housing.
Bei dem Getriebe handelt es sich, gemäß einer weiteren vorteilhaften Ausführung, um ein Planetengetriebe, und bei dem axial stirnseitig über Dämpfungselemente abgestützten Getriebebauteil um ein Hohlrad des Planetengetriebes, in welchem im Betrieb die Planetenräder abrollen.The transmission is, according to a further advantageous embodiment, a planetary gear, and in the axially frontally supported via damping elements gear member to a ring gear of the planetary gear, in which the planetary gears roll in operation.
