Description

Andrehvorrichtung für Verbrennungskraftmaschinen. Bei Andrehvorrichtungen, die das Ein- und Ausrücken des Antriebsritzels mittels eines Getriebes besorgen, wird die Einrückbewegung durch Zurückhalten des Ritzels gegenüber der Anwurfwelle eingeleitet. Dies soll zweckmäßig zugleich mit dem Anlaufen des Anwurfmotrns erfolgen. Das Ausrücken soll durch das Zurückbleiben der Anwurfwelle gegen. das vom anspringenden Verbrennungsmotor mitgenommene Ritzel herbeigeführt werden. Das Zurückbleiben der Anwurfwelle tritt aber nur dann scharf genug ein, wenn die Drehzahl des Anwurfmotors sicher begrenzt ist. Die bisher hierzu verwendete Lagerreibung (Filzlager) hat den Nachteil, daß sie schon während des Einrückens bremsend und daher störend wirkt.Starting device for internal combustion engines. For turning devices, who engage and disengage the drive pinion by means of a gearbox, the engagement movement is achieved by holding back the pinion against the starter shaft initiated. This should expediently take place at the same time as the start-up motor starts up. The disengagement is intended to counteract the retardation of the throwing shaft. that of the jumping Internal combustion engine driven pinion are brought about. That Lagging behind the starter wave only occurs sharply enough if the speed of the starter motor safe is limited. The previously used bearing friction (felt bearing) has the Disadvantage that it already has a braking and therefore disruptive effect during engagement.

Erfindungsgemäß wird das selbsttätige Ausrücken des Getriebes durch eine die Drehzahl des einen Getriebeteiles begrenzende Wirbelstrombremse gesichert. Es sind zwar Wirbelstrombremsen in Verbindung mit elektrischen Motoren für andere Zwecke Bekannt; beim Erfindungsgegenstand wird jedoch besonders deren Eigenschaft ausgenutzt, daß ihre bremsende Wirkung mit der Drehzahl rascher als einfach proportional ansteigt. Man kann daher durch geeignete Bemessung der Bremse bewirken, daß diese während des Einrückvorganges nahezu wirkungslos bleibt, während sie hei der durch das Anspringen des Verbrennungsmotors hervorgerufenen überschreitung der normalen Anwurfdrehzahl ein kräftiges Bremsmoment entwickelt. Es erfolgt daher das Ausrücken des Antriebsritzels infolge der scharf begrenzten Drehzahl der Anwurfwelle ungleich sicherer als bei den bisher bekannten Anordnungen.According to the invention, the automatic disengagement of the transmission is through an eddy current brake limiting the speed of one gear part is secured. It is true that eddy current brakes are used in conjunction with electric motors for others Purposes known; in the subject matter of the invention, however, their property is particularly important exploited that their braking effect with the speed is faster than simply proportional increases. You can therefore cause this by suitable dimensioning of the brake remains almost ineffective during the engagement process, while it is hot through the starting of the internal combustion engine caused exceeding the normal Starting speed developed a powerful braking torque. The disengagement therefore takes place of the drive pinion unequal due to the sharply limited speed of the starter shaft safer than with the previously known arrangements.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung. Die Welle a des hier dargestellten Anwurfmotors trägt in bekannter Weise ein Schraubengewinde b, auf dem sich das Antriebsritzel c bis zu dem Bund d verschieben kann. In seiner Endlage greift das Ritzel e in die am Schwungrad des Verbrennungsmotors angebrachte Verzahnung e ein. Der Anker f des Anwurfmotors ist mit einem elektrisch leitenden Mantel g umgeben, der als Wirbelstrombremse wirkt und bei einer bestimmten Drehzahl die weitere Beschleunigung des Motors verhindert. Die Einleitung des Einrückvorganges erfolgt durch mechanische Bremsung des Ritzels c mittels der Bremsbacke h. Diese ist an einem zweiarmigen Hebel!, k befestigt, der durch einen von dem Feldmagneten m abgezweigten Streufluß bewegt wird. Der Feldmagnet m trägt zu diesem Zweck einen Vorsprung 1, und der Arm k besteht aus magnetisch leitendem Material. Eine Feder n hält die Backe h bei stromlosem Mbtor hoch.The drawing shows an embodiment of the invention. The shaft a of the starting motor shown here carries in a known manner a screw thread b on which the drive pinion c can move up to the collar d. In its end position, the pinion e meshes with the toothing e attached to the flywheel of the internal combustion engine. The armature f of the starting motor is surrounded by an electrically conductive jacket g, which acts as an eddy current brake and prevents further acceleration of the motor at a certain speed. The engagement process is initiated by mechanical braking of the pinion c by means of the brake shoe h. This is attached to a two-armed lever !, K , which is moved by a leakage flux branched off from the field magnet m. The field magnet m carries a projection 1 for this purpose, and the arm k consists of magnetically conductive material. A spring n holds the jaw h up when the Mbtor is de-energized.

Der als Wirbelstrombremse dienende Mantel g kann in seiner Wirkungsweise auch durch massive Bandagen oder einen massiven Ankerkörper ersetzt werden. De elektrische Drehzahlbegrenzung kann auch durch eine zusätzliche Nebenschlußwicklung auf den Feldmagneten des Anwurfmotars bewirkt werden.The jacket g serving as an eddy current brake can in its mode of operation can also be replaced by massive bandages or a massive anchor body. De electric The speed can also be limited by an additional shunt winding on the Field magnets of the starting motor are effected.
