Description

Die Erfindung betrifft einen Fliehkraftregler für Brennkraftmaschinen nach dem Oberbegriff des ersten Anspruchs.The invention relates to a centrifugal governor for internal combustion engines according to the preamble of the first claim.

Fliehkraftregler übernehmen am Motor eine wichtige Regelfunktion. So wird mit ihnen z.B. die Steuerkante des Einspritzpumpenplungers in Abhängigkeit von der Drehzahl des Motors verstellt.Centrifugal governors perform an important control function on the engine. So with them e.g. the control edge of the injection pump plunger is adjusted depending on the speed of the engine.

Ein solcher Fliehkraftregler ist in der DE-B-1 187 855 beschrieben. Bei diesem Fliehkraftregler ist ein Reglermeßwerk mit einer die Motordrehzahl aufweisenden Reglerantriebswelle fest verbunden und dreht sich mit derselben Drehzahl. Das Reglermeßwerk besteht aus Fliehgewichten, die mit einer von ihrer Drehzahl abhängigen Kraft eine Muffe beaufschlagen, die auf der Reglerantriebswelle axial verschiebbar angeordnet ist. Zur Übertragung der axialen Muffenbewegung auf einen Reglerhebel ist auf dem Reglerhebel ein Wälzlager befestigt, dessen äußerer Lagerdeckel auf der Muffe abrollt. Das Wälzlager ist somit das Verbindungsglied zwischen den sich drehenden Teilen des Reglermeßwerkes bzw. der Muffe und dem Reglerhebel.Such a centrifugal governor is described in DE-B-1 187 855. In this centrifugal governor, a governor measuring mechanism is firmly connected to a governor drive shaft that has the engine speed and rotates at the same speed. The regulator measuring mechanism consists of centrifugal weights which act on a sleeve with a force dependent on their speed, which is arranged axially displaceably on the regulator drive shaft. In order to transmit the axial sleeve movement to a control lever, a roller bearing is attached to the control lever, the outer bearing cover of which rolls on the sleeve. The roller bearing is thus the link between the rotating parts of the regulator measuring mechanism or the sleeve and the regulator lever.

Der Erfindung liegt die Aufgabe zugrunde, einen Fliehkraftregler für Brennkraftmaschinen zu schaffen, bei dem das Verbindungsglied zwischen den sich drehenden Teilen des Reglermeßwerks und dem Reglerhebel ein baulich einfaches, weitgehend verschleißfreies, kompaktes und leichtes Bauteil darstellt.The invention has for its object to provide a centrifugal governor for internal combustion engines, in which the connecting member between the rotating parts of the regulator measuring mechanism and the regulator lever is a structurally simple, largely wear-free, compact and lightweight component.

Erfindungsgemäß wird dies dadurch gelöst, daß der Reglerhebel die Reglerantriebswelle umschließt und auf dem Reglerhebel zwei in Bezug auf die Reglerantriebswelle gegenüberliegende Kugellager angeordnet sind. Diese Kugellager können klein und leicht ausgebildet sein, da der Durchmesser der Reglerantriebswelle keine Rolle spielt. Der Fliehkraftregler ist somit im Hinblick auf das Verbindungsglied ein baulich einfaches, weitgehend verschleißfreies, kompaktes und leichtes Bauteil.According to the invention, this is achieved in that the regulator lever surrounds the regulator drive shaft and two ball bearings are arranged on the regulator lever opposite one another with respect to the regulator drive shaft. These ball bearings can be small and light because the diameter of the regulator drive shaft is irrelevant. The centrifugal governor is thus a structurally simple, largely wear-free, compact and lightweight component with regard to the connecting member.

Zur besseren Kraftübertragung sind zweckmäßigerweise die Kugellagerachsen parallel zur Reglerhebeldrehachse angeordnet.For better power transmission, the ball bearing axes are expediently arranged parallel to the control lever axis of rotation.

Da der Kugellagerdurchmesser vorteilhafterweise sehr klein gewählt ist, ist es empfehlenswert, Kugellager mit Dicht- oder Deckscheiben zu verwenden, da die sich im Motoröl befindlichen Fremdkörper sonst zu Beschädigungen an den relativ kleinen Kugeln und Rollbahnen führen können.Since the ball bearing diameter is advantageously chosen to be very small, it is recommended to use ball bearings with sealing or cover disks, since the foreign bodies in the motor oil can otherwise damage the relatively small balls and roller tracks.

Weitere Merkmale der Erfindung ergeben sich aus der Beschreibung und der Figur, die eine Ausführungsform der Erfindung zeigt und nachfolgend näher beschrieben ist.Further features of the invention result from the description and the figure, which shows an embodiment of the invention and is described in more detail below.

Die Figur zeigt schematisch einen Längs- und einen Querschnitt durch einen erfindundgsgemäßen Fliehkraftregler für Brennkraftmaschinen.The figure shows schematically a longitudinal and a cross section through an inventive centrifugal governor for internal combustion engines.

Der Fliehkraftregler besteht aus einer Reglerantriebswelle 1, die einen Fliehgewichtsträger 9 durchragt, der mit der Reglerantriebswelle 1 fest verbunden ist und sich mit deren Drehzahl dreht. Im Fliehgewichtsträger sind Fliehgewichte 3 eingesetzt, die eine auf der Reglerantriebswelle 1 axial verschiebbare Muffe 2 kraftbeaufschlagen. Je nach der Drehzahl der Reglerantriebswelle 1 bzw. der Fliehkraft der Fliehgewichte 3, wird die Muffe 2 mehr oder weniger axial auf der Reglerantriebswelle 1 verschoben. Diese axiale Verschiebung der Muffe 2 wird auf einen Reglerhebel 4 übertragen, der die Reglerantriebswelle 1 umschließt. Dazu sind auf dem Reglerhebel 4 zwei Kugellager 5 angeordnet, dessen äußere Lagerdeckel 6 auf der Muffe 2 abrollen.The centrifugal governor consists of a governor drive shaft 1 which projects through a centrifugal weight carrier 9 which is fixedly connected to the governor drive shaft 1 and rotates at its speed. In the centrifugal weight carrier, centrifugal weights 3 are used, which force a sleeve 2, which is axially displaceable on the regulator drive shaft 1. Depending on the speed of the regulator drive shaft 1 or the centrifugal force of the centrifugal weights 3, the sleeve 2 is displaced more or less axially on the regulator drive shaft 1. This axial displacement of the sleeve 2 is transmitted to a regulator lever 4 which surrounds the regulator drive shaft 1. For this purpose, two ball bearings 5 are arranged on the control lever 4, the outer bearing cover 6 of which roll on the sleeve 2.

Da der Reglerhebel 4 die Reglerantriebswelle 1 umschließt, sind die Kugellager 5 auf dem Reglerhebel 4 in Bezug auf die Reglerantriebswelle 4 gegenüberliegend angeordnet.Since the regulator lever 4 encloses the regulator drive shaft 1, the ball bearings 5 on the regulator lever 4 are arranged opposite one another with respect to the regulator drive shaft 4.

Die Kugellagerachse 7 ist parallel zur Reglerhebeldrehachse 8 angeordnet, um die Lagerkräfte zu mindern.The ball bearing axis 7 is arranged parallel to the regulator lever axis of rotation 8 in order to reduce the bearing forces.

Damit keine sich im Motoröl befindlichen Fremdkörper in die Kugellager 5 gelangen und dort zu Beschädigungen an den relativ kleinen Kugeln und Rollbahnen führen, ist das Kugellager 5 abgedichtet.The ball bearing 5 is sealed so that no foreign bodies in the engine oil get into the ball bearings 5 and cause damage to the relatively small balls and runways.

Der große Vorteil dieser erfindungsgemäßen Ausführung ist, daß die Kugellager sehr klein ausgebildet werden können, und somit der Fliehkraftregler ein baulich einfaches weitgehend verschleißfreies, kompaktes und leichtes Bauteil darstellt.The great advantage of this embodiment according to the invention is that the ball bearings can be made very small, and thus the centrifugal governor is a structurally simple, largely wear-free, compact and lightweight component.
