Description

Einstellvorrichtung für radial bewegliche Greifer an Treibrädern für Kraftfahrzeuge. Es ist bekannt, radial verschiebbare Greifer an Treibrädern für Kraftfahrzeuge anzuordnen, welche den Rädern ein gutes Fassen auf weichem Boden, Sandwegen, Ackern u. dgl. ermöglichen sollen und während der Bewegung des betreffenden Fahrzeuges eingestellt werden können.Adjustment device for radially movable grippers on drive wheels for Motor vehicles. It is known, radially displaceable gripper on drive wheels for To arrange motor vehicles, which give the wheels a good grip on soft ground, Sand paths, fields and the like should enable and during the movement of the relevant Vehicle can be adjusted.

Die vorliegende Erfindung besitzt gegenüber ähnlichen Vorrichtungen den Vorteil, daß das Einstellen der Greifer vom Führersitz aus während der Vor- oder Rückwärtsbewegung des betreffenden Fahrzeuges mittels Druckflüssigkeit geschieht, wodurch ein elastisches Fahren erzielt wird.The present invention has over similar devices the advantage that the grapple can be adjusted from the driver's seat during the or the vehicle concerned moves backwards by means of hydraulic fluid, whereby an elastic driving is achieved.

In der Zeichnung ist die Erfindung in einer beispielsweisen Ausführungsform dargestellt, und zwar zeigt Abb. I die Seitenansicht mit teilweisem Schnitt eines Treibrades für Kraftfahrzeuge mit der Greifereinstellvorrichtung, Abb.2 den Querschnitt eines solchen und Abb. 3 den vergrößert dargestellten Teil eines Längsschnittes. -Das Treibrad dreht sich mit Lder Nabe a auf dem Achsschenkel b der Fahrzeugachse. In diesem befindet sich der Kanal c zur Zuführung der Druckflüssigkeit, welcher oben in dem Achsschenkel b in die Radnabe a mündet. Hier ist ein sichelförmiger Teil d von dem Achsschenkel weggeschnitten. Von hier aus führen durch die Nabe a Kanäle c zum Hindurchtritt der Druckflüssigkeit zu den Zylindern f, um dieselbe auf die Kolben g wirken zu lassen. Die so erzielte Verschiebung der. Kolben g wird durch die fTbertragungssta.ngen h auf die Greifer i übertragen. Ein Zurückdrängen der jeweils belasteten Greifer i bzw. der Druckflüssigkeit in den Zylindern f wird dadurch verhütet, daß die Öffnungen der Kanäle e in der Radnabe a in dieser Stellung durch den Achsschenkel b abgeschlossen sind.In the drawing, the invention is shown in an exemplary embodiment, namely Fig. I shows the side view with a partial section of a drive wheel for motor vehicles with the gripper setting device, Fig.2 the cross section of such and Fig. 3 the enlarged part of a longitudinal section. -The drive wheel rotates with the hub a on the steering knuckle b of the vehicle axle. In this there is the channel c for supplying the pressure fluid, which opens into the wheel hub a at the top in the steering knuckle b. Here a sickle-shaped part d is cut away from the steering knuckle. From here pass through the hub a channels c for the passage of the pressure fluid to the cylinders f, in order to let the same act on the pistons g. The thus achieved shift of. Piston g is transferred to gripper i by means of transmission rods h. A pushing back of the loaded gripper i or the pressure fluid in the cylinders f is prevented by the fact that the openings of the channels e in the wheel hub a are closed in this position by the steering knuckle b.
