PATENTAMT.PATENT OFFICE.
Bei vorliegender Erfindung wird das Umsteuern von Gaskraftmaschinen durch eine Steuerung bewirkt, bei der sich die Steuerwelle, wie bekannt, stets in einer Richtung dreht.In the present invention, the reversing of gas engines by a Control causes the control shaft, as is known, always in one direction turns.
Von den bekannten Ausführungen dieser Art unterscheidet sich die Erfindung dadurch, daß die Kuppelungsklauen des Wendegetriebes, welches die Steuerwelle antreibt, alsThe invention differs from the known designs of this type in that that the coupling claws of the reversing gear, which drives the control shaft, as
ίο Gewindeteile ausgebildet sind, die außer einem selbsttätigen Einkuppeln der Steuerwelle auch ein selbsttätiges Einstellen der Nockenbündel, den Kurbelstellungen entsprechend, für die betreffende Laufrichtung des Motors besorgen.ίο threaded parts are formed that except an automatic coupling of the control shaft also an automatic adjustment of the Cam bundle, corresponding to the crank positions, for the relevant direction of travel of the engine.
Zum Umsteuern der Arbeitsventile sind dadurch keine weiteren Organe notwendig.As a result, no further organs are required to reverse the working valves.
Die Steuerwelle α wird mittels der Zwischenwelle b von 'der Kurbelwelle aus angetrieben. Die Verbindung zwischen den beiden ersteren , stellt ein Wendegetriebe her. Das Kegelrad c1 ist auf der Zwischenwelle befestigt, während die beiden anderen nicht . starr mit der Steuerwelle verbunden sind.The control shaft α is driven from the crankshaft by means of the intermediate shaft b. The connection between the two former, creates a reversing gear. The bevel gear c 1 is mounted on the intermediate shaft, while the other two are not. are rigidly connected to the control shaft.
Zum Verkuppeln der Steuerwelle mit dem Wendegetriebe dienen die Gewindeteile dx und d2, welche auf der Steuerwelle befestigt sind. Die Kegelräder c2 und cs sind mit Innengewinde versehen, so daß d1 in c2 und d2 in cz treten kann. Bei linkslaufender Zwischenwelle .schraubt sich der Gewindeteil d1 in das rechts umlaufende Kegelrad c2 und verriegelt so die Steuerwelle mit . demselben. Ändert der Motor seine Drehrichtung, so schraubt sich d1 aus c2 und d2 in cs hinein. Die Steuerwelle dreht sich also stets in einer Richtung und kuppelt sich selbttätig. The threaded parts d x and d 2 , which are attached to the control shaft, are used to couple the control shaft to the reversing gear. The bevel gears c 2 and c s are provided with internal threads, so that d 1 can occur in c 2 and d 2 in c z . When the intermediate shaft rotates to the left, the threaded part d 1 is screwed into the right-hand rotating bevel gear c 2 and thus also locks the control shaft. same. If the motor changes its direction of rotation, then d 1 screws from c 2 and d 2 into c s . The control shaft always rotates in one direction and couples itself automatically.
Da die Gewindeteile fest auf der Steuerwelle sitzen, muß diese sich in ihrer Längsachse verschieben. Diese beim Umkuppeln stattfindende Verschiebung dient zum Einstellen der Nockenbündel. Die Nocken der einzelnen Zylinder sind auf je einer gemeinschaftlichen Hülse befestigt. Die Nockenbündelhülsen f werden seitlich festgehalten. Innen sind sie mit Gewinde versehen, durch welches die auf der Steuerwelle befestigten Gewindeteile e gleiten. Die Steigung des Gewindes ist der Stellung der Kurbeln entsprechend. Since the threaded parts are firmly seated on the control shaft, it must move in its longitudinal axis. This shift, which takes place when the coupling is changed, is used to adjust the cam bundle. The cams of the individual cylinders are each attached to a common sleeve. The cam bundle sleeves f are held laterally. Inside they are provided with thread, through which the fixed to the control shaft threaded parts slide e. The pitch of the thread corresponds to the position of the cranks.
