Description

Wechsel- und Wendegetriebe für Kraftwagen u. dgl. Die Erfindung bezieht sich auf Wechsel-und Wendegetriebe für Kraftwagen a. dgl. nach Patent 421546 und besteht darin, daß die Erregungsringe der mit Reibungsschraubenfedern versehenen Kupplungen durch Federn ersetzt sind.Change and reversing gears for motor vehicles and the like focus on change and reversing gearboxes for motor vehicles a. Like. According to Patent 421546 and is that the excitation rings are provided with friction coil springs Clutches are replaced by springs.

Auf der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung dargestellt, und zwar zeigt Abb. i einen Längsschnitt durch einen Teil des Wechsel- und Wendegetriebes und Abb. 2 den Schnitt nach 2-2 der Abb. i, von links gesehen.In the drawing is an embodiment of the subject matter of Invention shown, namely Fig. I shows a longitudinal section through a part of the change and reversing gear and Fig. 2 the section according to 2-2 of Fig. i, from seen on the left.

Auf der vom Motor des Kraftwagens angetriebenen Hohlwelle A des Getriebes sind wie beim Gegenstande des Hauptpatentes durch Keile bi Hülsen B befestigt, von denen jede zusammen mit je einer auf der Hohlwelle A drehbar gelagerten Hülse C ein trommelartiges Gehäuse bildet. In jedes dieser Gehäuse ist eine Schraubenfeder b2 eingesetzt, deren eines Ende mittels eines Stiftes b3 mit der Hülse B verbunden ist. Gegen das andere Ende dieser Schraubenfeder b2 stützt sich von innen das eine Ende dl einer um die Nabe b4 der Hülse B gelegten Feder D, die mit ihrem anderen Ende d2 in der Nabe b4 befestigt ist. Mit der Feder D steht das eine Ende eines Bolzens E in Berührung, der durch die Nabe b4 der Hülse B und die Hohlwelle A radial hindurchgeführt ist. Das andere Ende dieses Bolzens stützt sich gegen die in der Hohlwelle A verschiebbare, mit Nocken f1 versehene Stange F.On the hollow shaft A of the transmission driven by the motor of the motor vehicle, as in the subject matter of the main patent, sleeves B are fastened by wedges, each of which forms a drum-like housing together with a sleeve C rotatably mounted on the hollow shaft A. A helical spring b2 is inserted into each of these housings, one end of which is connected to the sleeve B by means of a pin b3. Against the other end of this helical spring b2, one end dl of a spring D which is placed around the hub b4 of the sleeve B and which is fastened with its other end d2 in the hub b4 is supported from the inside. One end of a bolt E is in contact with the spring D and is guided radially through the hub b4 of the sleeve B and the hollow shaft A. The other end of this bolt is supported against the rod F, which is slidable in the hollow shaft A and provided with cams f1.

Befindet sich die Stange F in einer Stellung, in welcher der Nocken /l seitlich des Bolzens E liegt, so ist das Getriebe ausgerückt.The rod F is in a position in which the cam / l is to the side of bolt E, the gearbox is disengaged.

Soll das Getriebe eingeschaltet werden, so wird die Stange F so weit in der HohlwelleA verschoben, bis der Nocken. f l unter den Bolzen E tritt und diesen anhebt. Der Bolzen E drückt dann das Ende dl der Feder D gegen die Schraubenfeder b2 und kuppelt dadurch in bekannter Weise die Hülse C mit der fest auf der Hohlwelle A sitzenden Hülse B. If the transmission is to be switched on, the rod F is moved so far in the hollow shaft A until the cam. fl steps under bolt E and lifts it. The bolt E then presses the end dl of the spring D against the helical spring b2 and thereby couples the sleeve C to the sleeve B, which is firmly seated on the hollow shaft A, in a known manner.
