Description
Stand der TechnikState of the art
Heutzutage kommen in aller Regel elektrische Andrehvorrichtungen mit einem Rotor und einem Statorkammer, die aus einer geeigneten Stromquelle gespeist werden, zum Andrehen von Brennkraftmaschinen zum Einsatz. Das Andrehritzel ist üblicherweise starr mit der Rotorwelle des Elektromotors verbunden, z. B. auf diesen aufgepresst oder einstückig zu diesem ausgebildet. Die Stromzufuhr in den Rotor erfolgt im Allgemeinen über Bürsten und einen Kommutator, wohingegen der Stator mit Wicklungen und/oder mit Permanentmagneten ausgerüstet sein kann. Zur Erhöhung des Anlassdrehmomentes kann ein Zwischengetriebe, insbesondere ein Planetengetriebe eingesetzt werden. Das Ankerritzel treibt dann über das Zwischengetriebe das eigentliche Andrehritzel an. Zum Einspuren des Andrehritzels in den Zahlenkranz einer anzudrehenden Verbrennungskraftmaschine ist vielfach ein magnetisch betriebener Vorspulaktuator vorgesehen, der zum Einrücken des Andrehritzels in den Zahlenkranz an der Schwungscheibe der Verbrennungskraftmaschine dient. Zur Entkopplung der Andrehvorrichtung von der angesprungenen Brennkraftmaschine ist oftmals ein Freilauf vorgesehen.Nowadays, electrical starting devices with a rotor and a stator chamber, which are fed from a suitable power source, are generally used for starting internal combustion engines. The starter pinion is usually rigidly connected to the rotor shaft of the electric motor, e.g. B. pressed onto this or formed in one piece with this. The current is usually supplied to the rotor via brushes and a commutator, whereas the stator can be equipped with windings and / or with permanent magnets. An intermediate gear, in particular a planetary gear, can be used to increase the starting torque. The anchor pinion then drives the actual starter pinion via the intermediate gear. In order to engage the starter pinion in the number ring of an internal combustion engine to be turned on, a magnetically operated pre-actuating actuator is often provided, which serves to insert the starter pinion into the number ring on the flywheel of the internal combustion engine. A freewheel is often provided to decouple the starting device from the started internal combustion engine.
Treten jedoch beim Anlassvorgang der Verbrennungskraftmaschine Unregelmäßigkeiten auf, wie z. B. Fehlzündungen, unerwartete Rückwärtsdrehungen oder ein sogenannter Stoppschlag beim Blockieren der Verbrennungskraftmaschine, so wirken auf die Andrehvorrichtung extrem hohe mechanische Belastungen ein, die zur Beschädigung oder Zerstörung der Anlassvorrichtung führen können. Selbst bei normalen Startprozessen einer Verbrennungskraftmaschine treten durch die Auf- und Abwärtsbewegung der Kolben bei Kompression und Dekompression im Brennraum pulsierende Drehmomentstöße auf.However, irregularities occur during the starting process of the internal combustion engine, such as. B. misfires, unexpected reverse rotations or a so-called stop when blocking the internal combustion engine, act on the starter extremely high mechanical loads that can lead to damage or destruction of the starter. Even during normal starting processes of an internal combustion engine, pulsating torque surges occur due to the upward and downward movement of the pistons during compression and decompression in the combustion chamber.
Aus der
Die
Offenbarung der ErfindungDisclosure of the invention
Erfindungsgemäß wird eine Startvorrichtung zum Andrehen von Verbrennungskraftmaschinen mit den Merkmalen des Anspruchs 1 vorgeschlagen. Insbesondere wird vorgeschlagen, am Vorspuraktuator, insbesondere an einem in diesem linear beweglichen Anker mindestens ein Dämpfungs- bzw. Federelement vorzusehen, welches einen harten metallischen Kontakt zwischen dem im Vorspuraktuator linear beweglichen Anker einerseits und einen im Vorspuraktuator befindlichen Ankerrückschluss dämpft und idealerweise vollständig vermeidet. Dazu ist an einer Stirnseite des im Gehäuse des Vorspuraktuators linear beweglichen Ankers eine Abdeckscheibe vorgesehen, an der sich das beispielsweise als Spiralfeder ausgebildete Federelement befindet. Dieses ist seinerseits mit einem Abstützelement verbunden, das auf dem Zugelement, welches mit dem linear beweglichen Anker betätigt wird, angeordnet ist. Das Dämpfungselement dient bei voller Bestromung der den Anker bewegenden Spulen zusammen mit der Abdeckscheibe und dem Abstützelement als Rückhalteeinrichtung und bewirkt auf dem letzten Restweg des linear beweglichen Ankers in Richtung auf den Ankerrückschluss zu, dass der in diesem Falle stark beschleunigte linear im Gehäuse des Vorspuraktuators bewegliche Anker abgebremst wird, ohne die durch die Magnetspulen des Vorspuraktuators erzeugte Magnetkraft zu beeinträchtigen.According to the invention, a starting device for starting internal combustion engines with the features of claim 1 is proposed. In particular, it is proposed to provide at least one damping or spring element on the toe-in actuator, in particular on an armature that is linearly movable therein, which dampens and ideally completely avoids hard metallic contact between the armature, which is linearly movable in the toe-in actuator, on the one hand, and an armature yoke located in the toe-in actuator. For this purpose, a cover disk is provided on an end face of the armature that is linearly movable in the housing of the toe-in actuator, on which the spring element, which is designed, for example, as a spiral spring, is located. This in turn is connected to a support element which is arranged on the tension element, which is actuated with the linearly movable armature. When the coils moving the armature are fully energized, the damping element, together with the cover plate and the support element, serves as a retaining device and, on the last remaining path of the linearly movable armature in the direction of the armature yoke, causes the, in this case, strongly accelerated linearly movable in the housing of the toe-in actuator Armature is braked without affecting the magnetic force generated by the solenoid coils of the toe-in actuator.
Durch entsprechende Auslegung der erfindungsgemäß vorgeschlagenen Dämpfungsvorrichtung, die gewissermaßen als Rückhaltvorrichtung dient, kann der im Gehäuse des Vorspuraktuators bei voller Bestromung der Wicklungen bewegte linear bewegliche Anker abgebremst werden, insbesondere ein harter metallischer Aufschlag, der dem Ankerrückschluss zuweisenden Stirnseite des linear beweglichen Ankers und dem Ankerrückschluss selbst verhindert werden.By means of a corresponding design of the damping device proposed according to the invention, which serves as a retention device to a certain extent, the linearly movable armature moved in the housing of the toe-in actuator when the windings are fully energized can be braked, in particular a hard metallic impact, the end face of the linearly movable armature that assigns the armature yoke and the armature yoke themselves can be prevented.
Durch die erfindungsgemäß vorgeschlagene Lösung ist insbesondere gewährleistet, dass die Magnetkraft, die durch den Vorspuraktuator ausgeübt wird, nicht beeinträchtigt wird, so dass die maximal entsprechend der Dimensionierung des Vorspuraktuators erzeugbare Magnetkraftbetätigung, insbesondere eines als Gabelhebel ausgebildeten Hebels zum Einrücken des Andrehritzels, zur Verfügung steht.The solution proposed according to the invention ensures in particular that the magnetic force exerted by the toe-in actuator is not impaired, so that the maximum magnetic force actuation that can be generated in accordance with the dimensioning of the toe-in actuator is available, in particular a lever designed as a fork lever for engaging the starter pinion .
Die erfindungsgemäß vorgeschlagene Rückhalteeinrichtung lässt sich, da sie an der Außenseite von Standardkomponenten des Vorspuraktuators aufgenommen ist, problemlos nachrüsten, ohne dass Modifikationen am durch den linear beweglichen Anker betätigenden Zugelement, der seinerseits den Gabelhebel betätigt und/oder am im Vorspuraktuator linear beweglichen Anker erforderlich würden. Sämtliche Komponenten der erfindungsgemäß vorgeschlagenen Rückhalteeinrichtung sind an der Außenseite des Vorspuraktuators oberhalb des Antriebslagerschildes aufgenommen, so dass auch ein zusätzlicher Bauraum durch die erfindungsgemäß vorgeschlagene Rückhalteeinrichtung beansprucht wird.The restraint device proposed according to the invention, since it is accommodated on the outside by standard components of the toe-in actuator, can be easily retrofitted without modifications to the pulling element which actuates the linearly movable armature and which in turn actuates the fork lever and / or the armature which is linearly movable in the toe-in actuator . All components of the restraint device proposed according to the invention are accommodated on the outside of the toe-in actuator above the drive end shield, so that an additional installation space is also claimed by the restraint device proposed according to the invention.
