Description

Die Erfindung betrifft eine durch den Ventilatorriemen antreibbare Luftpumpe für Kraftwagen. Gegenstand der Erfindung ist eine besondere Ausführungsform einer Ausrückvorrichtung mit einer Reibungskupplung, welche . im Innern der Antriebsriemenscheibe gelagert ist, die selbst wieder ihr Lager auf dem Lagerstutzen der Kurbelwelle findet.The invention relates to an air pump for motor vehicles that can be driven by the fan belt. The invention relates to a particular embodiment of a release device with a friction clutch, which. stored inside the drive pulley which itself finds its bearing on the bearing neck of the crankshaft.

Abb. ι und 2 stellen zwei Längsschnitte to durch die Pumpe dar.Fig. Ι and 2 show two longitudinal sections to through the pump.

Der Kolben α wird in dem Zapfen ft durch die Kurbelstange ο von der Kurbelscheibe ζ auf der Welle i angetrieben. Die Welle i ist in dem Ansatz t des Kurbelgehäuses u gelagert und durch Vierkant und Schraube I mit dem Kegel f der Reibungskupplung verbunden. Sie wird mit dem Kegel durch die Schraubenfeder g an den Hohlkegel der Riemenscheibe h angepreßt, die auf Kugellager um den Ansatz i des Kurbelgehäuses läuft. Die Ausrückung der Kupplung gegen den Federdruck erfolgt durch eine Nockenwelle k, die sich quer über die Kurbelscheibe ζ erstreckt und durch Anschlag an diese bei Drehung des Handgriffes η die Welle i achsial verschiebt. An der Verschiebung nimmt auch die Kurbelstange 0 teil, und eine Feder q unter-' stützt bei der Ausrückung die Bewegung der Kurbelstange auf dem Zapfen ft. The piston α is driven in the pin ft by the connecting rod ο from the crank disk ζ on the shaft i . The shaft i is mounted in the shoulder t of the crankcase u and connected by a square and screw I to the cone f of the friction clutch. It is pressed with the cone by the helical spring g against the hollow cone of the belt pulley h , which runs on ball bearings around the shoulder i of the crankcase. The clutch is disengaged against the spring pressure by a camshaft k, which extends transversely over the crank disk ζ and axially displaces the shaft i by stopping it when the handle η is rotated. The connecting rod 0 also takes part in the displacement, and a spring q assists the movement of the connecting rod on the pin ft during disengagement.

Die Pumpe ist der Einfachheit halber nur mit den Auslaßkugelventilen c versehen, während der Lufteinlaß bei der hintersten Kolbenstellung durch die Löcher b in der Wand des Zylinders d erfolgt. - Um das Öl mit Sicherheit von der Leitung zu dem Luftschlauch fernzuhalten, wird der Ledeidichtungsstulpen e roch durch einen besonderen Stahlblechstulpen χ dauernd nach außen gepreßt, so daß auch bei dem, Rückgange keine Luft durchtritt und Öl mitreißt. Mit der Grundplatte r ist die Pumpe leicht überall anzuschrauben. For the sake of simplicity, the pump is only provided with the outlet ball valves c, while the air inlet in the rearmost piston position takes place through the holes b in the wall of the cylinder d . - In order to keep the oil away from the line to the air hose with certainty, the leather seal cuff e smell is constantly pressed out through a special sheet steel cuff χ , so that even during the decline, no air passes through and oil is carried away. With the base plate r , the pump can easily be screwed anywhere.

Patent-Ansprüche:Patent Claims: 1. Luftpumpe für Luftreifen von Kraftwagen und ähnlichen Fahrzeugen, dadurch gekennzeichnet, daß auf dem Lagerstutzen (t) der Kurbelwelle (i) die Antriebsriemenscheibe (Ji) gelagert und. durch eine Reibungskupplung (f) derart mit der Antriebswelle verbunden ist, daß durch Anschlag einer Nockenwelle (k) gegen die Kurbelscheibe (z) die Ausrückung durch achsiale Bewegung der Kurbelwelle gegen Federdruck erfolgt.1. Air pump for pneumatic tires of motor vehicles and similar vehicles, characterized in that the drive pulley (Ji) is mounted and on the bearing stub (t) of the crankshaft (i). is connected to the drive shaft by a friction clutch (f) in such a way that when a camshaft (k) hits the crankshaft disk (z), the disengagement occurs through axial movement of the crankshaft against spring pressure. 2. Bei der Luftpumpe nach Anspruch 1 ist die Anordnung der Kurbelstange derart, daß sie die1 Aus- und Einrückbewegung der Kupplung teilt und entsprechend mit ihrem Lager auf dem Kurbelzapfen {ft) gleitet.2. In the air pump according to claim 1, the arrangement of the connecting rod is such that it divides the 1 disengaging and engaging movement of the clutch and accordingly slides with its bearing on the crank pin {ft). 3. Die Anordnung einer Feder (q) auf dem Kolbenzapfen (ft) nach Anspruch 2, welche sich im Sinne der Begünstigung der Ausrückbewegung seitlich an das Lager in der Kurbellänge anlegt.3. The arrangement of a spring (q) on the piston pin (ft) according to claim 2, which rests on the side of the bearing in the crank length in the sense of favoring the disengagement movement.
