Abstract
Description
Die Erfindung betrifft ein Kraftfahrzeuggetriebe mit ölnebelgeschmierter zweireihiger Nadellagerung gemäß dem einteiligen Patentanspruch 1.The The invention relates to a motor vehicle transmission with oil mist lubricated Double row needle bearing according to the one-piece Claim 1.
Aus
der
Aufgabe der Erfindung ist es, ein Getriebe mit einem hohen Wirkungsgrad zu schaffen.task The invention is a transmission with a high efficiency to accomplish.
Diese Aufgabe wird mit den Merkmalen vom einteiligen Patentanspruch 1 gelöst.These The object is achieved with the features of the one-part patent claim 1 solved.
Die Ölnebelschmierung eines Kraftfahrzeuggetriebes hat im Verhältnis zur aufwändigen Druckölschmierung oder Schleuderölführung den Vorteil, dass der Wirkungsgrad des Gesamtgetriebes nicht negativ beeinflusst wird. Auch sind der konstruktive Aufwand und die Kosten für ein Ölnebelgeschmiertes Getriebe relativ gering.The oil mist lubrication a motor vehicle transmission has in relation to the complex pressure oil lubrication or Schleuderölführung the Advantage that the efficiency of the overall transmission is not negative being affected. Also, the design effort and costs for an oil mist lubricated gearbox relatively low.
Ein Vorteil von Nadellagern ist deren hohe Tragfähigkeit. Zweireihige Nadellager sind dabei gegenüber einreihigen Nadellagern mit sehr langen Nadeln besonders ausfallsicher.One Advantage of needle roller bearings is their high load capacity. Double row needle roller bearings are opposite single-row needle bearings with very long needles particularly fail-safe.
Ein Vorteil des Radialspiels von mindestens 5% des Nadelwälzkörperdurchmessers und des Axialspiels von mindestens 10% des Nadelwälzkörperdurchmessers ist der, dass relativ wenig Reibung an der Zahnradlagerung entsteht, so dass dort trotz Verzicht auf eine aufwändige Schmierung Verschleiß und Fresserscheinungen sicher ausgeschlossen sind. Da die Reibung nur gering ist, ist auch die Lebenserwartung des erfindungsgemäßen Kraftfahrzeuggetriebes sehr hoch.One Advantage of the radial clearance of at least 5% of the Nadelwälzkörperdurchmessers and the axial clearance of at least 10% of the Nadelwälzkörperdurchmessers is that relatively little friction occurs on the gear bearing, so there despite waiving a complex lubrication wear and galling sensation are safely excluded. Since the friction is low, so is the life expectancy of the motor vehicle transmission according to the invention very high.
Der Lagerkäfig kann insbesondere aus Stahlblech hergestellt sein.Of the bearing cage can be made in particular of sheet steel.
Eine Härtung und Phosphatierung der Nadelwälzkörper und des Lagerkäfigs aus Stahlblech führt darüber hinaus zu einem sicheren Betrieb der Zahnradlagerung bei Ölnebelschmierung.A hardening and phosphating the needle roller body and of the bearing cage made of sheet steel about that In addition to a safe operation of the gear bearing with oil mist lubrication.
Die Belastung und damit die Schmierungsnotwendigkeit eines Lagers erhöht sich mit dessen Drehzahl. Demzufolge bietet die Erfindung besondere Vorteile, wenn die Differenzdrehzahl zwischen dem nadelgelagerten Zahnrad und dessen zugehöriger Welle besonders groß ist. Insbesondere ist dies der Fall, wenn sich das Zahnrad gegenüber einem als stehend betrachteten Getriebegehäuse in die eine Richtung und die zugehörige Welle in die andere Richtung dreht.The Load and thus the lubrication need of a bearing increases with its speed. As a result, the invention offers particular advantages when the differential speed between the needle bearing gear and its associated Wave is especially big. In particular, this is the case when the gear opposite to a Standing considered gear housing in one direction and the associated wave in the other direction rotates.
Mittels Öltaschen an den Stirnseiten des Lagerkäfigs kann die Reibung in besonders vorteilhafter Weise verringert werden.By oil bags on the front sides of the bearing cage the friction can be reduced in a particularly advantageous manner.
Weitere Vorteile der Erfindung gehen aus den weiteren Patentansprüchen, der Beschreibung und der Zeichnung vor.Further Advantages of the invention will become apparent from the other claims, the Description and the drawing above.
Die Erfindung ist nachfolgend anhand eines Ausführungsbeispiels in drei Figuren näher beschrieben.The The invention is based on an embodiment in three figures described in more detail.

Eine
Schmiermittelzufuhr des Vorgelegegetriebes
In einer alternativen Ausgestaltung der Erfindung kann das Losrad auch das antreibende Zahnrad der Rückwärtsgang-Zahnradebene eines Vorgelegetriebes sein. In diesem Fall dreht das Rückwärtsgang-Losrad bei eingelegtem Vorwärtsgang gegensinnig zur zugehörigen Vorgelegewelle. Die geometrischen Erfordernisse und insbesondere die Anordnung der inneren Schaltung, welche zumeist aus Schaltgabeln oder Schaltschwingen besteht, bestimmen dabei, ob das Losrad auf der Vorgelegewelle oder der Getriebeausgangswelle angeordnet ist.In an alternative embodiment of the invention, the idler gear also the driving gear of the reverse gear level of a Be countershaft. In this case, the reverse idler gear turns with engaged forward gear in the opposite direction to the associated one Countershaft. The geometric requirements and in particular the arrangement of the inner circuit, which usually consists of shift forks or shift rockers, determine whether the idler gear on the countershaft or the transmission output shaft is arranged.
Alternativ kann die Nadellagerung auch bei jeder anderen Loslagerung Anwendung finden, bei welcher sich das Losrad mit sehr hoher Drehzahl bei Ölnebelschmierung gegenüber der zugehörigen Welle dreht. Dabei müssen sich das Losrad und die Welle nicht zwangsläufig bezüglich des als stehend betrachteten Getriebegehäuses gegensinnig drehen.alternative Needle bearing can also be used with any other floating bearing application find, in which the idler gear at very high speed with oil mist lubrication across from the associated Shaft turns. It must the idler gear and the shaft are not necessarily related to standing transmission case turn in opposite directions.
Die Axialabstützung des Nadellagerkäfigs muss nicht zwangsläufig die selbe Axialabstützung sein, an welcher sich auch das Losrad abstützt.The axial support Needle roller cage must not necessarily be the same axial support, on which also the loose wheel is supported.
Die Öltaschen müssen nicht gleichmäßig am Umfang verteilt sein. Solange Unwuchten sicher ausgeschlossen sind, können die Öltaschen auch ungleichmäßig verteilt sein, um Schwingungserscheinungen und Geräusche zu verhindern.The oil bags have to not even on the circumference be distributed. As long as imbalances are safely excluded, the oil pockets also distributed unevenly be to prevent vibration and noise.

A combination of the described features for different embodiments is also possible.
