Description

Die Erfindung bezieht sich auf einen Starter für eine Brennkraftmaschine nach dem Oberbegriff des Anspruches 1.The invention relates to a starter for an internal combustion engine according to the preamble of claim 1.

Stand der TechnikState of the art

Aus der DE 38 08 673 A1 ist ein elektrischer Starter für eine Brennkraftmaschine bekannt, der auf einer Ritzelwelle ein Starterritzel aufweist, welches mit einem Zahnkranz einer Brennkraftmaschine in Eingriff zu bringen ist. Die Ritzelwelle ist über eine Kupplung verschieblich mit einer Ankerwelle eines Elektromotors verbunden und wird von dieser rotierend angetrieben. Bei Betätigung der Kupplung über ein Einrückrelais wird die Ritzelwelle axial verschoben, wodurch das Starterritzel auf der Ritzelwelle in Eingriff mit dem Zahnkranz der Brennkraftmaschine gelangt.From the DE 38 08 673 A1 For example, an electric starter for an internal combustion engine is known, which has on a pinion shaft a starter pinion which is to be brought into engagement with a ring gear of an internal combustion engine. The pinion shaft is slidably connected via a clutch with an armature shaft of an electric motor and is driven in rotation by this. Upon actuation of the clutch via an engagement relay, the pinion shaft is axially displaced, whereby the starter pinion on the pinion shaft engages with the ring gear of the internal combustion engine.

Um sicherzustellen, dass beim Einspuren des Starterritzels in den Zahnkranz der Brennkraftmaschine das Starterritzel seine axiale Position auf der Ritzelwelle behält, muss die Position des Starterritzels auf der Ritzelwelle über geeignete Maßnahmen fixiert werden.To ensure that when the starter pinion meshes with the ring gear of the internal combustion engine, the starter pinion retains its axial position on the pinion shaft, the position of the starter pinion on the pinion shaft must be fixed by means of suitable measures.

In der JP 8 035472 A wird ein elektrischer Starter für eine Brennkraftmaschine beschrieben, bei dem das Starterritzel auf einer zylindrischen Hülse auf der Ritzelwelle aufsitzt und die axiale Position des Starterritzels auf der Ritzelwelle über einen Klemmring gesichert ist, der in eine umlaufende Nut in der Mantelfläche der Ritzelwelle eingesetzt ist.In the JP 8 035472 A an electric starter for an internal combustion engine is described, in which the starter pinion is seated on a cylindrical sleeve on the pinion shaft and the axial position of the starter pinion on the pinion shaft is secured by a clamping ring which is inserted into a circumferential groove in the lateral surface of the pinion shaft.

Aus der GB 2 256 900 A ist ein elektrischer Starter für eine Brennkraftmaschine bekannt, dessen Starterritzel einteilig mit der axial verschieblichen Ritzelwelle ausgebildet ist. Die Axialbewegung der Ritzelwelle wird sowohl bei der axialen Vorschubbewegung als auch bei der Rückstellbewegung von Anschlägen auf der Ankerwelle des antreibenden Elektromotors begrenzt.From the GB 2 256 900 A an electric starter for an internal combustion engine is known, the starter pinion integral with the axially displaceable pinion shaft is trained. The axial movement of the pinion shaft is limited both in the axial feed movement and in the return movement of stops on the armature shaft of the driving electric motor.

In der JP 58 092469 U wird eine Anschlagseinrichtung für die Vorschubbewegung eines Starterritzels beschrieben, wobei die Anschlagseinrichtung eine Hülse mit radial auskragendem Bund auf der Ankerwelle des Elektromotors aufweist.In the JP 58 092469 U a stopping device for the advancing movement of a starter pinion is described, wherein the stop means comprises a sleeve with radially projecting collar on the armature shaft of the electric motor.

Bei einem in der JP 53 055037 U offenbarten Starter ist auf der Ankerwelle ein Klemmring in einer Nut angeordnet, wobei der Klemmring die axiale Vorschubbewegung der Ritzelwelle begrenzt.At one in the JP 53 055037 U disclosed starter is arranged on the armature shaft, a clamping ring in a groove, wherein the clamping ring limits the axial feed movement of the pinion shaft.

Offenbarung der ErfindungDisclosure of the invention

Der Erfindung liegt die Aufgabe zugrunde, mit einfachen konstruktiven Maßnahmen die Position eines Starterritzels auf der Ritzelwelle eines Starters zu fixieren.The invention has for its object to fix the position of a starter pinion on the pinion shaft of a starter with simple design measures.

Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruches 1 gelöst. Die Unteransprüche geben zweckmäßige Weiterbildungen an.This object is achieved with the features of claim 1. The dependent claims indicate expedient developments.

Der erfindungsgemäße Starter, beispielsweise ein frei ausstoßender Starter, wird elektrisch angetrieben und zum Starten eines Verbrennungsmotors eingesetzt. Die Ritzelwelle ist Träger eines Starterritzels, welche bei einer Vorschubbewegung in Eingriff mit einem Zahnkranz der Brennkraftmaschine gelangt. Die axiale Vorschubbewegung der Ritzelwelle wird üblicherweise über ein Einrückrelais ausgelöst, bei dessen Betätigung ein Einrückhebel die Ritzelwelle axial in die Einrückposition zwischen Starterritzel und Zahnkranz der Brennkraftmaschine vorschiebt. Mit dem Erreichen der Einrück- bzw. Eingriffsposition wird üblicherweise ein Schaltkontakt geschlossen und der Startermotor eingeschaltet, welcher in der Regel über ein Getriebe, beispielsweise ein Planetengetriebe, die Ritzelwelle antreibt.The starter according to the invention, for example a freely ejecting starter, is electrically driven and used to start an internal combustion engine. The pinion shaft is a carrier of a starter pinion, which comes in a feed movement into engagement with a ring gear of the internal combustion engine. The axial feed movement of the pinion shaft is usually triggered by an engagement relay, upon actuation of which an engagement lever advances the pinion shaft axially into the engagement position between the starter pinion and ring gear of the internal combustion engine. When the engagement or engagement position is reached, a switching contact is usually closed and the starter motor is switched on, which as a rule drives the pinion shaft via a gear, for example a planetary gear.

Zur Begrenzung der axialen Vorschubbewegung der Ritzelwelle ist vorteilhaft eine Anschlagseinrichtung vorgesehen. Desweiteren ist erfindungsgemäß zur Sicherung des Starterritzels auf der Ritzelwelle eine weitere Anschlagseinrichtung vorgesehen, die eine Sicherungshülse umfasst, welche als Bundhülse ausgeführt ist und einen radial auskragenden Bund aufweist, der einen Anschlag für das Starterritzel bildet, das auf der Ritzelwelle aufsitzt. Die Sicherungshülse ist in die Stirnseite der Ritzelwelle eingeführt, welche zumindest im stirnseitigen Abschnitt der Ritzelwelle als Hohlwelle ausgebildet ist. Der radial auskragende Bund der Sicherungshülse steht radial über die Mantelfläche der Ritzelwelle über und bildet den Anschlag für das auf der Ritzelwelle aufsitzende Starterritzel.To limit the axial feed movement of the pinion shaft advantageously a stop device is provided. Furthermore, a further stop device is provided according to the invention for securing the starter pinion on the pinion shaft, which comprises a securing sleeve, which is designed as a collar sleeve and has a radially projecting collar which forms a stop for the starter pinion, which rests on the pinion shaft. The securing sleeve is inserted into the end face of the pinion shaft, which is designed as a hollow shaft at least in the frontal section of the pinion shaft. The radially projecting collar of the locking sleeve projects radially beyond the lateral surface of the pinion shaft and forms the stop for the starter pinion seated on the pinion shaft.

Diese Ausführung hat den Vorteil, dass auf die im Stand der Technik üblichen Spreng- und Halteringe, welche die Anschlagseinrichtung auf der Ritzelwelle bilden, verzichtet werden kann. Hierdurch wird eine Reduzierung der für die Anschlagseinrichtung erforderlichen Bauteile erzielt. Ein weiterer Vorteil liegt in der umlaufenden, geschlossenen Form der Sicherungshülse, wodurch die Sicherungshülse drehzahlunempfindlich wird. Ein weiterer Vorteil ist die innen liegende Anordnung der Sicherungshülse über die Stirnseite der als Hohlwelle ausgebildeten Ritzelwelle, so dass eine Anordnung der Anschlagseinrichtung auf der äußeren Mantelfläche der Ritzelwelle entfallen und die Ritzelwelle axial kürzer ausgeführt sein kann. Zudem müssen in die äußere Mantelfläche der Ritzelwelle keine Nuten zur Aufnahme eines Sicherungsrings oder dergleichen eingebracht werden.This embodiment has the advantage that it is possible to dispense with the blasting and retaining rings customary in the prior art, which form the stop device on the pinion shaft. As a result, a reduction of the components required for the stop device is achieved. Another advantage lies in the circumferential, closed shape of the locking sleeve, whereby the locking sleeve is insensitive to speed. Another advantage is the internal arrangement of the locking sleeve on the end face of the pinion shaft designed as a hollow shaft, so that an arrangement of the stop means on the outer surface of the pinion shaft omitted and the pinion shaft can be made axially shorter. In addition, no grooves for receiving a securing ring or the like must be introduced into the outer circumferential surface of the pinion shaft.

Grundsätzlich ist es für die Aufnahme der Sicherungshülse ausreichend, dass die Ritzelwelle nicht durchgehend, sondern lediglich im Bereich der Stirnseite als Hohlwelle ausgeführt ist, in die die Sicherungshülse einführbar ist. Vorteilhafterweise ist aber die Ritzelwelle durchgehend als Hohlwelle ausgeführt.Basically, it is sufficient for receiving the securing sleeve, that the pinion shaft is not continuous, but only in the region of the front side designed as a hollow shaft into which the securing sleeve is inserted. Advantageously, however, the pinion shaft is designed continuously as a hollow shaft.

Die Sicherungshülse bildet in einer vorteilhaften Ausführung zugleich eine Lagerbuchse für eine Antriebswelle, die in der Ritzelwelle aufgenommen ist.The securing sleeve forms in an advantageous embodiment at the same time a bearing bush for a drive shaft, which is accommodated in the pinion shaft.

Gemäß einer zweckmäßigen Ausführung liegt der radial auskragende Bund der Sicherungshülse an der Stirnseite der Ritzelwelle unmittelbar an. Der Bund steht radial über die Mantelfläche der Ritzelwelle über und bildet einen axialen Anschlag für die Stirnseite des Starterritzels, welches auf der Ritzelwelle aufsitzt. Hierbei kommen sowohl Ausführungen in Betracht, in denen die Stirnseite des Starterritzels eine ebene Scheibe bildet, an der der Bund in Anschlagsposition anliegt, als auch Ausführungen mit einer in die Stirnseite des Starterritzels eingebrachten Ringnut zur Aufnahme des auskragenden Bundes der Sicherungshülse; die letztgenannte Ausführung hat den Vorteil, dass der in die Ringnut eingreifende Bund der Sicherungshülse eine axial kleiner bauende Ausführung des Starters erlaubt.According to an expedient embodiment of the radially projecting collar of the locking sleeve is located on the front side of the pinion shaft directly. The collar projects radially beyond the lateral surface of the pinion shaft and forms an axial stop for the end face of the starter pinion, which is seated on the pinion shaft. In this case, both versions come into consideration, in which the end face of the starter pinion forms a flat disc on which the collar rests in stop position, as well as versions with an introduced into the face of the starter pinion ring groove for receiving the cantilever collar of the locking sleeve; the last-mentioned embodiment has the advantage that the collar of the securing sleeve engaging in the annular groove permits an axially smaller design of the starter.

Gemäß einer weiteren zweckmäßigen Ausführung ist an der Innenwand der Ritzelwelle eine Ringschulter gebildet, an der eine axiale Stirnseite der Sicherungshülse anliegt. Die Ringschulter bildet einen Absatz, an welchem sich die Sicherungshülse axial abstützt.According to a further advantageous embodiment, an annular shoulder is formed on the inner wall of the pinion shaft, against which an axial end face of the securing sleeve. The annular shoulder forms a shoulder on which the securing sleeve is axially supported.

Die Verbindung zwischen Sicherungshülse und Ritzelwelle kann form-, kraft-und/oder stoffschlüssig erfolgen. So ist es beispielsweise möglich, die Sicherungshülse in die stirnseitige Ausnehmung in der Ritzelwelle einzupressen, wodurch eine kraftschlüssige Verbindung hergestellt wird. Zusätzlich oder alternativ können an der außen liegenden Wandung der Sicherungshülse und der Innenwand der Ritzelwelle Rastelemente gebildet sein, die bei eingesetzter Sicherungshülse ineinander verrastet sind; hierbei handelt es sich um eine form- bzw. kraftschlüssige Verbindung. Die Rastelemente sind beispielsweise als überstehende Rastnasen und Rastausnehmungen ausgebildet, die in eingesetzter Position der Sicherungshülse verrastend ineinandergreifen.The connection between the locking sleeve and pinion shaft can be positive, force and / or material fit. For example, it is possible to press the locking sleeve into the frontal recess in the pinion shaft, whereby a non-positive connection is made. Additionally or alternatively, latching elements can be formed on the outer wall of the locking sleeve and the inner wall of the pinion shaft, which are latched into each other with inserted locking sleeve; This is a positive or non-positive connection. The latching elements are formed, for example, as protruding latching lugs and latching recesses which engage in latching fashion in the inserted position of the securing sleeve.

In den Figuren sind gleiche Bauteile mit gleichen Bezugszeichen versehen.In the figures, the same components are provided with the same reference numerals.

Der in den Fig. 1 und 2 dargestellte Starter 1 dient zum Starten einer Brennkraftmaschine und weist eine Ritzelwelle 2 auf, welche über eine motorisch angetriebene, in den Figuren nicht dargestellte Antriebswelle von einem Elektromotor angetrieben wird. Die Ritzelwelle 2 ist im Bereich ihrer freien Stirnseite Träger eines Starterritzels 3, das als separates, eigenständiges Bauteil ausgeführt ist und auf der Mantelfläche der Ritzelwelle 2 aufsitzt und drehfest mit der Ritzelwelle verbunden ist. Zum Starten der Brennkraftmaschine wird die Ritzelwelle 2 axial vorgerückt, woraufhin das Starterritzel 3, welches mit einer Außenverzahnung 4 versehen ist, in Verzahnungseingriff mit einem Zahnkranz der Brennkraftmaschine gelangt. Über eine Drehung der Ritzelwelle 2 sowie des Starterritzels 3, erzeugt über die Antriebswelle, wird die Brennkraftmaschine zum Laufen gebracht.The in the Fig. 1 and 2 illustrated starter 1 is used to start an internal combustion engine and has a pinion shaft 2, which is driven by a motor driven, not shown in the figures drive shaft by an electric motor. The pinion shaft 2 is in the region of its free end side carrier of a starter pinion 3, which is designed as a separate, independent component and is seated on the lateral surface of the pinion shaft 2 and rotatably connected to the pinion shaft. To start the internal combustion engine, the pinion shaft 2 is axially advanced, whereupon the starter pinion 3, which is provided with external teeth 4, comes into meshing engagement with a ring gear of the internal combustion engine. About a rotation of the pinion shaft 2 and the starter pinion 3, generated via the drive shaft, the internal combustion engine is made to run.

Die axiale Position des Starterritzels 3 auf der Mantelfläche der Ritzelwelle 2 wird zum einen über einen Sicherungsring 5 und zum anderen über eine Sicherungshülse 6 gesichert. Der Sicherungsring 5 ist beispielsweise als Sprengring ausgebildet und auf die Mantelfläche der Ritzelwelle 2 aufgeschoben. Diese weist einen außen liegenden, sich radial erhebenden Absatz auf, an welchem der Sicherungsring 5 anliegt. Das Starterritzel 3 stützt sich axial an dem Sicherungsring 5 ab.The axial position of the starter pinion 3 on the lateral surface of the pinion shaft 2 is secured on the one hand via a locking ring 5 and the other via a locking sleeve 6. The securing ring 5 is formed for example as a snap ring and pushed onto the lateral surface of the pinion shaft 2. This has an outer, radially uplifting paragraph on which the locking ring 5 is applied. The starter pinion 3 is supported axially on the retaining ring 5.

Auf der dem Sicherungsring 5 gegenüberliegenden, axial außen liegenden Seite befindet sich die Sicherungshülse 6, die einen zylindrischen Abschnitt 7 sowie einen radial auskragenden Bund aufweist, welcher einen Anschlag für das Star-territzel 3 bildet, dessen axiale Stirnfläche am Bund 8 anliegt. Die Ritzelwelle 2 ist als Hohlwelle ausgeführt, der zylindrische Abschnitt 7 der Sicherungshülse 6 ist in die Ritzelwelle 2 eingepresst, wodurch ein sicherer Sitz der Sicherungshülse innerhalb der Ritzelwelle gegeben ist. Der radial auskragende, nach außen gestülpte Bund 8 der Sicherungshülse 6 liegt unmittelbar an der Stirnseite der Ritzelwelle 2 an und erstreckt sich radial bis in den Bereich des Starterritzels 3.On the securing ring 5 opposite, axially outer side is the locking sleeve 6, which has a cylindrical portion 7 and a radially projecting collar, which has a stop for the star-terr 3 forms, the axial end face rests on the collar 8. The pinion shaft 2 is designed as a hollow shaft, the cylindrical portion 7 of the locking sleeve 6 is pressed into the pinion shaft 2, whereby a secure fit of the locking sleeve is provided within the pinion shaft. The radially projecting, turned-out collar 8 of the securing sleeve 6 abuts directly on the end face of the pinion shaft 2 and extends radially into the region of the starter pinion third

Zum Starten der Brennkraftmaschine muss die Ritzelwelle 2 einschließlich Starterritzel 3 axial ausgespurt und zugleich mit einer Drehbewegung gesteuert werden. Dies erfolgt über ein Einrückrelais, das über einen Einrückhebel eine Kraft auf einen Mitnehmer 9 ausübt, der mit der Ritzelwelle 2 verbunden ist. Die Ritzelwelle 2 ist über ein als Innengewinde ausgeführtes Steilgewinde 10 mit der Antriebswelle verbunden, so dass bei einer Betätigung des Einrückrelais die Ritzelwelle 2 gegenüber der Antriebswelle sowohl eine Vorschubbewegung als auch eine Drehbewegung ausführt. Mit dem Betätigen des Einrückrelais wird ein Schaltkontakt geschlossen, woraufhin der elektrische Startermotor eingeschaltet wird, dessen Antriebsbewegung über ein Getriebe auf die Antriebswelle und von dieser über das Steilgewinde auf die Ritzelwelle 2 und damit auf das Starterritzel 5 übertragen wird. Nach dem Abschalten des Einrückrelais wird der Anlassvorgang beendet, zugleich wird der elektrische Startermotor abgeschaltet und die Ritzelwelle 2 über eine Feder 11 wieder in ihre Ruhelage zurückverstellt.To start the internal combustion engine, the pinion shaft 2 including starter pinion 3 has to be axially spoked out and at the same time controlled with a rotary movement. This is done via an engagement relay, which exerts a force on a driver 9 via an engagement lever, which is connected to the pinion shaft 2. The pinion shaft 2 is connected via a helical thread 10 designed as an internal thread to the drive shaft, so that upon actuation of the engagement relay, the pinion shaft 2 executes both a feed movement and a rotational movement relative to the drive shaft. With the actuation of the contact relay, a switching contact is closed, whereupon the electric starter motor is turned on, the drive movement is transmitted via a transmission to the drive shaft and from there via the coarse thread on the pinion shaft 2 and thus on the starter pinion 5. After switching off the engagement relay of the starting process is terminated, at the same time the electric starter motor is switched off and the pinion shaft 2 is returned by a spring 11 back to its rest position.

In Fig. 2 ist ein ähnlicher Starter 1 wie in Fig. 1 dargestellt, so dass bezüglich der Funktionsweise auf die obige Ausführung verwiesen wird. Im Vergleich zum ersten Ausführungsbeispiel weist die Sicherungshülse 6 in der Ritzelwelle 2 Modifikationen auf. Der zylindrische Abschnitt 7 der Sicherungshülse 6 ist verhältnismäßig kurz ausgebildet. Die nach innen einragende Stirnseite des zylindrischen Abschnitts 7 liegt an einer Ringschulter 12 an der Innenwand der Ritzelwelle 2 an, so dass die Ringschulter 12 einen Anschlag für die Sicherungshülse 6 bildet. Die sichere Halterung der Sicherungshülse 6 in der Ritzelwelle 2 erfolgt über Rastelemente 13 an der Innenwand der Ritzelwelle 2 bzw. der Außenwand des zylindrischen Abschnitts 7 der Sicherungshülse 6, wobei die Rastelemente 13 in der eingeschobenen Stellung der Sicherungshülse in der Rastposition stehen. Die Rastelemente sind beispielsweise als Rastnasen und Rastausnehmungen ausgeführt. Aufgrund der Verrastung der Rastelemente 13 genügt grundsätzlich eine kürzere axiale Länge des zylindrischen Abschnitts 7. Gegebenenfalls ist der zylindrische Abschnitt 7 zusätzlich in die Ritzelwelle 2 eingepresst.In Fig. 2 is a similar starter 1 as in Fig. 1 so that reference is made to the above embodiment with respect to the operation. Compared to the first embodiment, the locking sleeve 6 in the pinion shaft 2 modifications. The cylindrical portion 7 of the locking sleeve 6 is relatively short. The inwardly projecting end face of the cylindrical portion 7 abuts against an annular shoulder 12 on the inner wall of the pinion shaft 2, so that the annular shoulder 12 forms a stop for the securing sleeve 6. The secure mounting of the locking sleeve 6 in the pinion shaft 2 via locking elements 13 on the inner wall of the pinion shaft 2 and the outer wall of the cylindrical portion 7 of the locking sleeve 6, wherein the locking elements 13 are in the retracted position of the locking sleeve in the locking position. The locking elements are designed for example as locking lugs and recesses. Due to the locking of the locking elements 13 is sufficient in principle a shorter axial length of the cylindrical portion 7. Optionally, the cylindrical portion 7 is additionally pressed into the pinion shaft 2.

Auch an der Stirnseite des Starterritzels 3 ist eine Ringschulter 14 gebildet, in die der radial auskragende Bund 8 der Sicherungshülse 6 einragt.Also on the front side of the starter pinion 3, an annular shoulder 14 is formed, in which the radially projecting collar 8 of the locking sleeve 6 protrudes.

Das Starterritzel 3 wird axial von einem Federelement 15 kraftbeaufschlagt, das sich am Gehäuse des Starters abstützt und das Starterritzel 3 gegen den Bund 8 der Sicherungshülse drückt.The starter pinion 3 is subjected to a force of force axially by a spring element 15, which is supported on the housing of the starter and presses the starter pinion 3 against the collar 8 of the securing sleeve.
