Die Erfindung betriSt eine Andrehvorrichtung für Brennkraftmaschinen, bei der ein von einem Andrehmotor angetriebenes Andrehritzel axial bis zum Eingriff in ein Getrieberad der Brennkraftmaschine bewegt wird und das Andrehritzel durch eine Rückf iihr-Vorrichtung am unbeabsichtigten Eingreifen in das Getrieberad der Brennkraftmaschine bei Nichtgebrauch der Andrehvorrichtung gehindert wird.The invention concerns a cranking device for internal combustion engines, in which one of a cranking motor driven starter pinion moved axially until it engages a gear wheel of the internal combustion engine and the starting pinion is prevented from inadvertently engaging in the Gear of the internal combustion engine is prevented when the cranking device is not in use.
Bei Nichtbenutzung der Andrehvorrichtung wird der Läufer des Andrehmotors, beispielsweise durch eine Rückführfeder, vom Stator des Motors zurückgezogen, während bei Unterstromsetzung des Andrehmotors sich der Läufer wie bei einem Solenoid in Längsrichtung bewegt. Bisher wurde die Rückführfeder auch zur Sicherung des Läufers des Andrehmotors gegen Drehung bei Nichtgebrauch der Andrehvorridhtung benutzt. Dies ist nachteilig, denn diese Rückführfeder darf nicht sehr stark sein, weil sie sonst bei Gebrauch des Andrehmotors die Axialbewegung des Läufers behindert. Handelt es sich beispielsweise um eine Andrehvorrichtung für den Motor eines Tanks, der steile Abhänge befährt, dann kommt oft das Andrehritzel mit dem angetriebenen Rad in Berührung.When the cranking device is not used, the rotor of the cranking motor is, for example, through a return spring, withdrawn from the stator of the motor while energizing the cranking motor the rotor moves lengthways like a solenoid. So far the return spring has been also to secure the rotor of the starting motor against rotation when the starting device is not in use used. This is disadvantageous because this return spring must not be very strong because otherwise it will hinder the axial movement of the rotor when the starter motor is used. Is it for example about a cranking device for the engine of a tank that drives down steep slopes, then comes often the starting pinion is in contact with the driven wheel.
Gegenstand der Erfindung ist die Ausbildung einer solchen Rückführvorrichtung.The subject of the invention is the formation of such a return device.
Gemäß der Erfindung besteht die Rückführvorrichtung aus einer sich mit dem Antriebsritzel drehenden und mit diesem axial verschieblichen Hülse, die eine sich über mehr als 180° erstreckende Umfangsnut hat, in die, wenn die Andrehvorrichtung nicht gebraucht wird, zwei in Umfangs- und in axialer Richtung versetzte Feststellteile durch Federkraft eingedrückt werden, so daß bei sich drehendem Andrehritzel die Feststellteile aus der Umfangsnut heraustreten, und sich somit das Andrehritzel axial bewegen und in das Getrieberad der Brennkraftmaschine eingreifen kann.According to the invention, the return device consists of a rotating with the drive pinion and with this axially displaceable sleeve, which has a circumferential groove extending over more than 180 ° has, in which, when the turning device is not needed, two in the circumferential and in the axial direction offset locking parts are pressed in by spring force, so that when the starter pinion rotates the locking parts emerge from the circumferential groove, and thus move the starter pinion axially and can intervene in the gear wheel of the internal combustion engine.

vorgesehene Schwungrad? der Brennkraftmaschine eingreift. Die Hülse 4 ist zwecks Bewegung in Axialrichtung und in Umfangsrichtung in einem Lager 8 einer Verlängerung des Gehäuses 2 gelagert. In den Umfang der Hülse ist eine Umfangsnut 9 eingearbeitet, die sich über mehr als 180°, zweckmäßig über etwa 320° erstreckt, und die Enden dieser Nut haben eine sich allmählich verringernde Tiefe. In der Hülse 4 sind zwei federbelastete, sich gegenüberliegende kolbenförmige Feststellteile 10 a, 10 b angeordnet, die mit ihren inneren Enden in die Nut 9 eingreifen, wenn die Andrehvorrichtung nicht benutzt wird.intended flywheel? the internal combustion engine intervenes. The sleeve 4 is mounted in a bearing 8 of an extension of the housing 2 for the purpose of movement in the axial direction and in the circumferential direction. A circumferential groove 9 is machined into the circumference of the sleeve and extends over more than 180 °, expediently over approximately 320 °, and the ends of this groove have a gradually decreasing depth. In the sleeve 4, two spring-loaded, opposite piston-shaped locking parts 10 a, 10 b are arranged, which engage with their inner ends in the groove 9 when the turning device is not used.
Bei Benutzung der Andrehvorrichtung wird der Andrehmotor unter Strom gesetzt, und der Läufer 1 dreht sich und bewegt sich zusammen mit der Hülse 4 und dem Andrehritzel 6 in axialer Richtung. Diese Bewegung wird zunächst von wenigstens einem der Feststellteile 10 a, 10 b verhindert. Jedoch wird jeder Feststellteil einmal während jeder Umdrehung aus der Nut 9 herausbewegt, und zwar an der Stelle, wo die Hülse 4 keine Umfangsnut hat. Wenn der Feststellteil 10 α aus der Nut heraustritt, dann kann sich die Hülse frei bewegen, bis der Einstellteil 10 b von der hinteren Wand der Nut berührt wird. Diese Axialbewegung reicht aus, um einen Wiedereingriff des Einstellteils 10 α in die Nut 9 zu verhindern. Wenn dann nach weiteren 90° der Einstellteil 10 b aus der Nut heraustritt, dann kann sich die Hülse 4 ungehindert bis zum Eingriff des Andrehritzels 6 in das Getrieberad des Schwungrades 7 bewegen. Bei der BewegungWhen using the starting device, the starting motor is energized and the rotor 1 rotates and moves together with the sleeve 4 and the starting pinion 6 in the axial direction. This movement is initially prevented by at least one of the locking parts 10 a, 10 b. However, each locking part is moved out of the groove 9 once during each revolution, namely at the point where the sleeve 4 has no circumferential groove. When the locking part 10 α emerges from the groove, the sleeve can move freely until the adjustment part 10 b is touched by the rear wall of the groove. This axial movement is sufficient to prevent the adjustment part 10 from reengaging into the groove 9. If then, after a further 90 °, the setting part 10 b emerges from the groove, the sleeve 4 can move unhindered until the starter pinion 6 engages in the gear wheel of the flywheel 7. When moving
