Abstract

The proposal is for an engaging gear for internal combustion engine starters. The engaging gear has a freewheel (8), whose inner race (9) with the starter pinion (10) is arranged in relation to the outer race (7) with the drive bush (5) via an additional axial springing system. During meshing and slippage, especially in the case of tooth-on-tooth contact, the inner race (9) is so unstably engaged with the starter pinion (10) that the starter pinion (10) can more easily enter the next tooth-in-recess position in the starter ring gear (28) of the internal combustion engine to be started.

Einspurσetriebe für Andrehvorrichtunσen von BrennkraftmaschinenSingle-track gearbox for starting devices of internal combustion engines
Stand der TechnikState of the art
Die Erfindung geht von einem Einspurgetriebe für λndrehvorrichtungen von Brennkraftmaschinen nach der Gattung des Hauptanspruchs aus. Bei solch einer bekannten Andrehvorrichtung sind die Laufringe des Frei¬ laufs lediglich gegeneinander verdrehbar, jedoch nicht gegeneinander axial verschiebbar angeordnet. Das kann beim Einspurvorgang, wenn das Andrehritzel mit großer Kraft auf den Zahnkranz trifft und nicht gleich in eine Zahnlücke einspuren kann, zu Frühausfällen des Ein¬ spurgetriebes durch "Einspurratschen" führen.The invention is based on a single-track transmission for λndrehvorrichtungen of internal combustion engines according to the preamble of the main claim. In such a known starting device, the races of the freewheel are only rotatable relative to one another, but are not axially displaceable relative to one another. During the engagement process, when the starter pinion hits the ring gear with great force and cannot immediately engage in a tooth gap, this can lead to early failures of the engagement transmission due to "engagement ratchets".
Aufgabe, Lösung und Vorteile der ErfindungObject, solution and advantages of the invention
Der Erfindung liegt die Aufgabe zugrunde, ein Einspurgetriebe für Andrehvorrichtungen zu schaffen, dessen Lebensdauer mit einfachen, für eine wirtschaftliche Großmengenfertigung geeigneten Mitteln wesentlich verlängert werden kann.The invention has for its object to provide a single-track transmission for starting devices, the lifespan of which can be significantly extended with simple means suitable for economical large-scale production.
Zur Lösung der Aufgabe sind die im Kennzeichen des Hauptanspruchs angegebenen Maßnahmen vorgesehen. The measures specified in the characterizing part of the main claim are provided to achieve the object.
Dabei ist von Vorteil, daß durch seine zusätzliche axial federnd nachgiebige Anordnung das Andrehritzel in der Einspur- und in der Durchdrehphase des Andrehvorgangs instabil gelagert ist und gedämpft auf den Zahnkranz prallt, dabei durch zusätzlich entstehende Eigen¬ schwingungen vor allem bei Zahn-auf-Zahn-Stellung leichter in die nächste Zahn-auf-Lücke-Stellung gelangt, eine gleichmäßigere Abnutzung an den Zahnflanken des Andrehritzels und des Zahnkranzes auftritt und auch der Verzicht auf ein Nebenschlußfeld ermöglicht werden kann.The advantage here is that, due to its additional axially resilient arrangement, the starter pinion is mounted unstably in the single-track and in the spinning phase of the start-up process and bounces against the ring gear in a damped manner, due to additional natural vibrations, especially with tooth-on-tooth Position more easily reaches the next tooth-on-gap position, more even wear occurs on the tooth flanks of the pinion and the ring gear and it is also possible to dispense with a shunt field.
Durch die in den ünteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen des im Hauptanspruch angegebenen Einspurgetriebes möglich. Besonders vorteilhaft ist eine aus mindestens einer Tellerfeder bestehende Federanordnung, die zwischen innerem Laufring und Mitnehmerhülse eingesetzt ist.The measures listed in the subclaims allow advantageous developments of the single-track transmission specified in the main claim. A spring arrangement consisting of at least one plate spring, which is inserted between the inner race and the driving sleeve, is particularly advantageous.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung darge¬ stellt und in der nachfolgenden Beschreibung n her erläutert. Sie zeigt ein Einspurgetriebe mit einem Teil einer Andrehvorrichtung im Längsschnitt.An embodiment of the invention is shown in the drawing and explained in the following description. It shows a single-track transmission with part of a starter in longitudinal section.
Beschreibung des AusführungsbeispielesDescription of the embodiment
Eine Andrehvorrichtung ist in an sich bekannter und nicht näher dargestellter Weise mit einem Andrehmotor versehen. Dessen Anker¬ welle erstreckt sich mit einem als Antriebswelle 1 dienenden Abschnitt durch ein am Andrehmotor angeordnetes Antriebslager 2. Das Ende der Antriebswelle 1 ist in einem Gleitlager 3 des Antriebs¬ lagers 2 drehbar aufgenommen. Die Antriebswelle 1 ist mit einem Steilgewindeabschnitt 4 versehen, auf dem eine Mitnehmerhülse 5 mit einer Innenverzahnung verschraubbar sitzt. Die Mitnehmerhülse 5 ist einstückig mit einem Flansch 6 und mit einem äußeren Laufring 7 eines Freilaufs 8 ausgebildet. Ein innerer Laufring 9 des Freilaufs 8 ist ebenfalls einstückig mit einem Andrehritzel 10 ausgebildet und dreh- und verschiebbar auf der Antriebswelle 1 gelagert. Die Lauf- ringe 7 und 9 schließen Kammern 11 ein, in denen Rollen 12 unter¬ gebracht sind, welche sich in an sich bekannter und nicht näher dargestellter Weise auf in den Kammern 11 untergebrachten Federn abstützen. Die Kammern 11 sind an ihrer Stirnseite mit einer Deck¬ scheibe 13 verschlossen, an der eine Anschlagseheibe 14 anliegt. Die Freilaufteile 7, 9, 10 und 12 bis 14 werden von einem über den äußeren Laufring 7 und die Anschlagscheibe 14 greifenden Deckel 15 zusam engehalten.A starter is provided with a starter motor in a manner known per se and not shown in detail. Its armature shaft extends with a section serving as the drive shaft 1 through a drive bearing 2 arranged on the starting motor. The end of the drive shaft 1 is rotatably received in a slide bearing 3 of the drive bearing 2. The drive shaft 1 is provided with a high-thread section 4, on which a driving sleeve 5 with an internal toothing sits. The driving sleeve 5 is in one piece with a flange 6 and with an outer race 7 a freewheel 8 is formed. An inner race 9 of the freewheel 8 is also formed in one piece with a starter pinion 10 and is rotatably and displaceably mounted on the drive shaft 1. The races 7 and 9 enclose chambers 11, in which rollers 12 are accommodated, which are supported in a manner known per se and not shown in more detail on springs accommodated in the chambers 11. The chambers 11 are closed on their end face by a cover disk 13 against which a stop washer 14 bears. The freewheel parts 7, 9, 10 and 12 to 14 are held together by a cover 15 which engages over the outer race 7 and the stop disk 14.
Am Übergang des inneren Laufrings 9 zum Andrehritzel 10 ist eine Ringnut 16 ausgebildet. In die Ringnut 16 ragt die Anschlagscheibe 14 mit axialem Spiel. In der Stirnseite 17 des inneren Laufrings 9 ist eine ringscheibenförmige Ausnehmung 18 ausgebildet. In die Aus¬ nehmung 18 ist eine Tellerfeder 19 eingesetzt. Sie stützt sich mit ihrem äußeren Rand an der Stirnseite 20 der Mitnehmerhülse 5 ab. Zwischen dem inneren Laufring 9 und der Anschlagscheibe 14 bleibt dabei noch ein Mindestspiel erhalten, um zwischen diesen Teilen unerwünschte Reibungseinflüsse zu vermeiden. Die Laufringe 7 und 9 liegen dann etwa um die verbleibende Länge der Ringnut 16 des inneren Laufrings 9 axial versetzt zueinander. Dabei steht die Stirnseite 17 des inneren Laufrings 9 um die Größe dieses Spiels von der Stirnseite 20 der Mitnehmerhülse ab.An annular groove 16 is formed at the transition from the inner race 9 to the starting pinion 10. The stop disk 14 projects into the annular groove 16 with axial play. An annular disk-shaped recess 18 is formed in the end face 17 of the inner race 9. A disc spring 19 is inserted into the recess 18. It is supported with its outer edge on the end face 20 of the driving sleeve 5. A minimum clearance is still maintained between the inner race 9 and the stop disk 14 in order to avoid undesirable friction influences between these parts. The races 7 and 9 are then axially offset from one another approximately by the remaining length of the annular groove 16 of the inner race 9. The end face 17 of the inner race 9 protrudes from the end face 20 of the driving sleeve by the size of this play.
Auf der Mitnehmerhülse 5 ist eine Einrückmuffe 21 bewegbar ange¬ ordnet. Sie ist in der in der Zeichnung dargestellten Ruhelage von einer Einspurfeder 22 an einen Anschlagring 23 der Mitnehmerhülse 5 gedrückt. Die Einspurfeder 22 stützt sich dabei am Flansch 6 ab. An der Einrückmuffe 21 ist ein gabelförmiger Einrückhebel 24 angelenkt. Der Einrückhebel 24 ist um seine Lagerstelle 25 am Antriebslager 2 mittels eines an sich bekannten und nicht näher dargestellten elek¬ tromagnetischen Schalters schwenkbar. Auf der Antriebswelle 1 ist nahe ihrem im Gleitlager 3 aufgenommenen Ende ein Anschlagring 26 angeordnet. Durch eine maulartige Öffnung 27 des Antriebslagers 2 ragt ein Zahnkranz 28 der anzudrehenden Brennkraftmaschine in den Bereich des Andrehritzels 10.An engagement sleeve 21 is movably arranged on the driving sleeve 5. It is pressed in the rest position shown in the drawing by an engagement spring 22 against a stop ring 23 of the driving sleeve 5. The engagement spring 22 is supported on the flange 6. A fork-shaped engagement lever 24 is articulated on the engagement sleeve 21. The engagement lever 24 can be pivoted about its bearing point 25 on the drive bearing 2 by means of an electromagnetic switch which is known per se and is not shown in detail. A stop ring 26 is arranged on the drive shaft 1 near its end received in the slide bearing 3. Through a mouth-like opening 27 of the drive bearing 2, a ring gear 28 of the internal combustion engine to be rotated projects into the area of the starter pinion 10.
Zum Andrehen der Brennkraftmaschine wird zunächst das Andrehritzel 10 in den Zahnkranz 28 der Brennkraftmaschine eingespurt. Dazu schwenkt der nicht dargestellte elektromagnetische Schalter den Einrückhebel 24 im Uhrzeigersinn um die Lagerstelle 25. Über die Einrückmuffe 21 wird die Mitnehmerhülse 5 samt Freilauf 8 und Andrehritzel 10 auf den Zahnkranz 28 zu vorgespurt. Trifft das Andrehritzel 10 in Zahn-auf-Lücke-Stellung an den Zahnkranz 28, dann spurt es sofort in den Zahnkranz 28 ein. Der elektromagnetische Schalter schließt in bekannter Weise den Andrehmotor an eine Strom¬ quelle, so daß er anläuft. Dabei wird das Andrehritzel 10 bis zum Anschlagring 26 auf der Antriebswelle 1 geschoben, und der Andreh¬ motor dreht über die Antriebswelle 1, die Mitnehmerhülse 5, den Freilauf 8 und das Andrehritzel 10 die Brennkraftmaschine an.To start the internal combustion engine, the starter pinion 10 is first engaged in the ring gear 28 of the internal combustion engine. For this purpose, the electromagnetic switch, not shown, pivots the engaging lever 24 clockwise around the bearing point 25. If the starter pinion 10 hits the ring gear 28 in the tooth-on-gap position, then it immediately engages in the ring gear 28. The electromagnetic switch connects the starter motor to a current source in a known manner, so that it starts up. The starter pinion 10 is pushed up to the stop ring 26 on the drive shaft 1, and the starter motor rotates the internal combustion engine via the drive shaft 1, the driving sleeve 5, the freewheel 8 and the starter pinion 10.
Trifft das Andrehritzel 10 beim Vorspuren auf den Zahnkranz 28 in Zahn-auf-Zahn-Stellung, dann kann das Andrehritzel 10 nicht sofort einspuren. Der elektromagnetische Schalter schwenkt jedoch den Einrückhebel 24 weiter im Uhrzeigersinn und spannt dabei über die Einrückmuffe 21 die Einpurfeder 22. Die Tellerfeder 19 wirkt der Einspurfeder 22 entgegen, so daß das Andrehritzel 10 durch seine instabile Lage noch eine gewisse Bewegbarkeit gegenüber der Mit¬ nehmerhülse 5 behält und durch zusätzliche Eigenschwingungen leichter an den Zahnflanken des Zahnkranzes 28 in die nächste Zahn-auf-Lücke-Stellung rutschen kann.If the starter pinion 10 hits the toothed ring 28 in tooth-to-tooth position during the toe-in, then the starter pinion 10 cannot engage immediately. However, the electromagnetic switch pivots the engaging lever 24 further clockwise and thereby tensioning the engagement spring 22 via the engagement sleeve 21. The plate spring 19 counteracts the engagement spring 22, so that the starter pinion 10, due to its unstable position, still has a certain mobility with respect to the driving sleeve 5 retains and can slip more easily on the tooth flanks of the ring gear 28 in the next tooth-on-gap position by additional natural vibrations.
Dabei kann das Andrehritzel 10 an die jeweils nähere rechte oder linke Zahnflanke des Zahnkranzes 28 in Einspurstellung gelangen. Liegt dann der innere Laufring 9 mit seiner Stirnseite 17 an der Stirnseite 20 der Mitnehmerhülse 5 an, wird das Andrehritzel 10 über den Freilauf 8 durch die Kraft der gespannten Einspurfeder 22 in den Zahnkranz 28 eingespurt und die Brennkraftmaschine wird angedreht.The starter pinion 10 can reach the respective closer right or left tooth flank of the ring gear 28 in the engagement position. Then lies the inner race 9 with its end face 17 on the end face 20 of the driving sleeve 5, the starter pinion 10 is over the freewheel 8 is engaged by the force of the tensioned engagement spring 22 in the ring gear 28 and the internal combustion engine is turned on.
In der Überholphase des Andrehvorgangs, wenn der Zahnkranz 28 das Andrehritzel 10 schneller dreht als der Anlaßmotor, ist die Teller¬ feder 19 unwirksam. Der Freilauf 8 wird in an sich bekannter Weise gelöst, so daß der Andrehmotor nicht überdreht wird und/oder die Andrehvorrichtung nicht durch stoßartige Beanspruchung beschädigt wird. Ist die Brennkraftmaschine angelaufen, wird ebenfalls in bekannter Weise die Andrehvorrichtung von der Stromzufuhr abge¬ schaltet und die Andrehvorrichtung samt Einspurgetriebe in die Ruhe¬ stellung zurückbewegt. In the overtaking phase of the starting process, when the ring gear 28 turns the starter pinion 10 faster than the starter motor, the plate spring 19 is ineffective. The freewheel 8 is released in a manner known per se so that the starter motor is not overturned and / or the starter device is not damaged by sudden stress. When the internal combustion engine has started up, the starter device is likewise switched off from the power supply in a known manner and the starter device together with the single-track gear is moved back into the rest position.
