Abstract
Description
Die Erfindung bezieht sich auf eine Getriebewelle, insb. auf eine Vorgelegewelle für ein Getriebe bzw. ein Doppelkupplungsgetriebe nach dem Oberbegriff des Anspruchs 1.The The invention relates to a transmission shaft, esp. On a countershaft for a transmission or a dual-clutch transmission the preamble of claim 1.
Aus
der
Der Erfindung liegt die Aufgabe zugrunde, eine Getriebewelle, insbesondere eine Vorgelegewelle für ein Getriebe bzw. ein Doppelkupplungsgetriebe eines Kraftfahrzeugs zu schaffen, über die mittels Ölzuführungsbohrungen eine gleichmäßige Zuführung von Schmieröl zu axial hintereinander auf der Welle angeordneten Lagerstellen, auch bei verschiedenen Drehzahlbereichen, sichergestellt ist.Of the Invention is based on the object, a transmission shaft, in particular a countershaft for a transmission or a dual clutch transmission to create a motor vehicle, via the means of oil supply holes a uniform supply of lubricating oil bearing points arranged axially one behind the other on the shaft, even at different speed ranges, is ensured.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.These The object is achieved by the features of claim 1. Further advantageous features include the dependent claims.
Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, dass durch eine zentrale direkte Ölversorgung bzw. Ölzuführung zu Lagerstellen für Los- und/oder Festräder des Getriebes alle Lagerstellen unabhängig vom Drehzahlbereich mit Schmieröl versorgt werden können. Dies wird in vorteilhafter Weise nach der Erfindung erreicht, indem die Getriebewelle im Bereich von axial hintereinander auf der Welle angeordneten Lagerstellen von einer Axialbohrung ausgehende radiale Ölzuführungsbohrungen mit zunehmendem Durchmesser vorgesehen sind, derart, dass durch die zunehmenden Durchmesser der radialen Ölzuführungsbohrungen der zugeführte Ölvolumenstrom regulierbar wird.The consist with the invention mainly achieved advantages in that by a central direct oil supply or oil supply to bearings for loose and / or fixed wheels of Gearboxes all bearings regardless of the speed range can be supplied with lubricating oil. this will achieved in an advantageous manner according to the invention by the transmission shaft in the range of axially successively arranged on the shaft bearings from an axial bore outgoing radial oil supply holes are provided with increasing diameter, such that by the increasing diameter of the radial oil supply holes the supplied oil volume flow is adjustable.
Hierzu ist nach einer weiteren Ausführung der Erfindung vorgesehen, dass die Getriebewelle an einem Ende mit einer Ölzuführungseinrichtung oder einer Öleinspritzdüse verbunden ist, mittels der ein Ölstrahl bis zum abgekehrten geschlossenen Ende der Axialbohrung der Getriebewelle einspritzbar ist.For this is provided according to a further embodiment of the invention, that the transmission shaft at one end with an oil supply device or an oil injection nozzle is connected by means of a jet of oil until the remote end of the closed Axial bore of the gear shaft is injectable.
Damit eine gezielte gleichmäßige Ölversorgung aller Lagerstellen erreicht wird, ist des Weiteren nach der Erfindung vorgesehen, dass der Ölstrahl koaxial zur Axialbohrung der Getriebewelle und berührungsfrei zur Wandfläche der Axialbohrung an dem nicht mit der Ölversorgung verbundenem und geschlossenem Ende der Getriebewelle auftreffend ist.In order to a targeted uniform oil supply is reached all bearings, is further according to the invention provided that the oil jet coaxial with the axial bore the gear shaft and non-contact to the wall surface the axial bore at the not connected to the oil supply and closed end of the transmission shaft is incident.
Da das Schluckvermögen der radialen Ölzuführungsbohrungen unmittelbar in Nähe des auftreffenden Ölstrahls am größten ist, wird nach der Erfindung des Weiteren vorgeschlagen, dass die radialen Ölzuführungsbohrungen zu den Lagerstellen vom geschlossenen Ende der Axialbohrung der Getriebewelle bis zur Öleinspritzdüse Querschnitte mit einem ansteigenden Durchmesser aufweisen.There the absorption capacity of the radial oil supply holes immediately near the impinging jet of oil is largest, according to the invention further suggested that the radial oil supply holes to the bearings from the closed end of the axial bore of the Transmission shaft up to oil injector cross sections having an increasing diameter.
Nach einer Bauausführung der Erfindung ist vorgesehen, dass zumindest vier Lagerstellen mit radialen Ölzuführungsbohrungen in der hohlen Getriebewelle angeordnet sind und die Ölzuführungsbohrungen vom geschlossenen Ende der Axialbohrung der Welle sich von einem kleinen Durchmesser bis zur Einspritzdüse kontinuierlich im Durchmesser vergrößern.To A construction of the invention is provided that at least four bearings with radial oil supply holes are arranged in the hollow gear shaft and the oil supply holes from the closed end of the axial bore of the shaft itself small diameter to the injector continuously increase in diameter.
In konkreter Ausgestaltung der Erfindung sind die beiden ersten Lagerstellen auf der Getriebewelle mit radialen Ölzuführungsbohrungen gleichen Durchmessers ausgeführt und die sich anschließenden Ölzuführungsbohrungen für die dritte und für die vierte Lagerstelle sind jeweils mit ansteigenden Durchmessern versehen.In concrete embodiment of the invention, the two first bearings on the gear shaft with radial oil supply holes same diameter running and the subsequent oil supply holes for the third and the fourth depository are each provided with increasing diameters.
Durch die Ausführung der radialen Ölzuführungsbohrungen mit ansteigendem Durchmesser vom geschlossenen Ende der Axialbohrung in der Getriebewelle aus, wird in vorteilhafter Weise erreicht, dass unabhängig von der Drehzahl der Welle alle Lagerstellen gleichmäßig mit Schmiermittel versorgt werden können bzw. ein gleiches Schluckvermögen erreicht wird, obwohl einige Lagerstellen entfernt von der direkten Ölzuführung am geschlossenem Ende der Axialbohrung angeordnet sind.By the execution of the radial oil supply holes with increasing diameter from the closed end of the axial bore in the gear shaft, is achieved in an advantageous manner that regardless of the speed of the shaft all bearings be supplied evenly with lubricant can or an equal swallowing capacity achieved Although some bearings are removed from the direct oil supply are arranged at the closed end of the axial bore.
