Description

Vorrichtung zum Verhüten des Ölaustritts aus: dem Getriebegehäuse von Kraftfahrzeugen. Bei Kraftfahrzeugen, insbesondere bei Motorrädern, die durch Explosionsmotoren angetrieben werden, ist es ein stets lästig empfundener Übelstand, daß die Getriebegehäuse nicht öldicht sind und schon nach kurzer Betriebsdauer an den undichten Stellen, besonders an den Austrittsstellen der Getriebewelle, öl herausläuft, das den Wagen und bei Motorrädern die Kleider des Fahrers beschmutzt und der Maschine ein ungepflegtes Aussehen gibt. Um diesen Übelstand zu. beseitigen, wird gemäß der Erfindung der Innenraum des: Gehäuses an da,- Saugrohr des Motors angeschlossen, so daß der äußere Luftdruck ein Austreten des Öles an den undichten Stellen verhindert.Device to prevent oil leakage from: the gearbox housing of motor vehicles. In motor vehicles, especially in motorcycles, through Explosion engines are driven, it is an annoyance always felt annoying, that the gear housing is not oil-tight and will come on after a short period of operation oil leaks out of the leaks, especially at the exit points of the gear shaft, that stains the car and, in the case of motorcycles, the clothes of the driver and the machine an unkempt appearance gives. To this evil too. remove, According to the invention, the interior of the: housing on there, - intake manifold of the engine connected so that the external air pressure leakage of the oil to the leaking Places prevented.

Die Erfindung ist auf der Zeichnung beispielsweise an einem Einzylindermotorrad veranschaulicht.The invention is shown in the drawing, for example, on a single cylinder motorcycle illustrated.

i ist der Motorzylinder, z das Kurbelgehäuse, 3 die Auspuffleitung und q. die Ansaugeleitung des Motors. An der Ansaugeleitung sitzt der Vergaser 5 mit dem Drosselorgan 6. 7 ist das Getriebegehäuse.i is the engine cylinder, z the crankcase, 3 the exhaust pipe and q. the intake line of the engine. The carburetor 5 is located on the intake line with the throttle element 6. 7 is the gear housing.

Gemäß der Erfindung wird zwischen dem Saugrohr q. und dein Getriebegehäuse 7 :eine Verbindung durch eine Leitung 8 hergestellt. Infolgedessen tritt bei laufendem Motor im Innern des Getriebegehäuses Unterdruck auf, dessen Größe durch entsprechende Wahl des Querschnittes der Verbindungsleitung 8 beherrscht werden kann und stets so klein bleibt, daß das Öl nicht angesaugt wird.According to the invention between the suction pipe q. and your gearbox 7: a connection established through a line 8. As a result occurs while running Motor inside the gear housing on negative pressure, its size by corresponding Choice of the cross section of the connecting line 8 can be mastered and always remains so small that the oil is not sucked in.

Da bei einem Einzylindermotor der Unterdruck in der Saugleitung zwischen den einzelnen Saugperioden. verlorengeht, ist es notwendig, daß in die Verbindungsleitung 8 ein Rückschlagventil eingeschaltet wird, das einen Druckausgleich in dem Getriebegehäuse verhindert. Diesem Zweck dient im Ausführungs; beispiel ein Kugelventil 9, dessen Gehäuse io .durch eine Lochplatte i i mit dem Saugrohr in Verbindung steht. Die Lochplatte verhindert, daß während der Saugperiode die Kugel in die Saugleitung gesaugt wird. In dem Getriebegchäuse 7 bleibt daher dauernd ein Unterdruck aufrechterhalten. Der Unterdruck der äußeren Atmosphäre wirkt daher dem Ausfließen ,des Öles aus etwa. undichten Stellen, insbesondere an den Lagern der Getriebewelle entgegen.Since in a single cylinder engine the negative pressure in the suction line is between the individual suction periods. is lost, it is necessary that in the connection line 8 a non-return valve is switched on, the pressure equalization in the gear housing prevented. This is the purpose in execution; example a ball valve 9, whose Housing io. Is connected to the suction pipe through a perforated plate i i. the Perforated plate prevents the ball from entering the suction line during the suction period is sucked. A negative pressure is therefore permanently maintained in the transmission housing 7. The negative pressure of the outer atmosphere therefore affects the outflow of the oil from about. against leaks, especially at the bearings of the gear shaft.

Bei vier- und mehrzylindrigen Motoren ist die Anordnung des Rückschlagventils 9 entbehrlich, -da bei:, .diesen ,der Unterdruck in der Saugleitung q. nicht verlorengeht.In four- and multi-cylinder engines, the arrangement of the check valve is 9 can be dispensed with, because with :, .these, the negative pressure in the suction line q. is not lost.
