Abstract

The device (1) has an oil injection pipe (3) comprising a nozzle (4) and/or a cross hole, which are attached to a component i.e. gear teeth (2), to be lubricated. The nozzle and/or the cross hole comprise a drip edge (5) via which strongly viscous dripping oil reach the component to be lubricated, where the drip edge is integrally casted or welded at the nozzle and/or at the cross hole. The drip edge is formed such that oil dispersed by the component is absorbed and is dripped back on the component in warm condition of the oil.

Description

Die vorliegende Erfindung bezieht sich auf Einrichtung zur Beölung von Bauteilen eines Getriebes gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to a device for lubricating Components of a transmission according to the preamble of claim 1

Aus dem Stand der Technik sind Einrichtungen zur Beölung von Bauteilen eines Getriebes bekannt. Die bekannten Einrichtungen umfassen Öleinspritzleitungen, welche in der Regel als Querbohrungen ausgeführte Bohrungen oder eingesetzte Düsen aufweisen, über die das Öl an die zu beölenden Bauteile geleitet werden soll.Out The prior art are devices for lubrication of components of a transmission known. The known devices include oil injection pipes, which usually executed as cross holes bores or used Have nozzles over the the oil to oil them Components should be directed.

Hierbei weisen die Bohrungen bzw. die Düsen aufgrund deren Form und der Einspritzgeometrie einen definierten Abstand zum zu beölenden Bauteil, beispielsweise zur zu beölenden Verzahnung auf, was bei sehr viskosem und somit abtropfendem Öl in nachteiliger Weise darin resultiert, dass das Öl das zu beölende Bauteil nicht erreichen kann. Dies ist insbesondere bei niedrigen Temperaturen der Fall, bei denen die Viskosität derart steigt, dass das Öl lediglich tropfen kann.in this connection have the holes or the nozzles due to their shape and the injection geometry a defined Distance to oil Component, for example, to be oiled teeth on what with very viscous and thus dripping oil disadvantageously in it that results in the oil that to be oiled Can not reach the component. This is especially at low Temperatures of the case where the viscosity increases so much that the oil only can drip.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zur Beölung von Bauteilen eines Getriebes anzugeben, durch die die Beölung der Bauteile auch bei sehr viskosem Öl sicherstellt wird.Of the present invention is based on the object, a device for lubrication specify of components of a transmission through which the lubrication of the Components even with very viscous oil is ensured.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere erfindungsgemäße Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor.These The object is solved by the features of claim 1. Further Embodiments of the invention and advantages are apparent from the dependent claims.

Demnach wird eine Einrichtung zur Beölung von Bauteilen eines Getriebes vorgeschlagen, umfassend eine Öleinspritzleitung, die zumindest eine Düse und/oder Querbohrung aufweist, wobei die zumindest eine Düse bzw.Therefore is a device for lubrication of Components of a transmission proposed, comprising an oil injection pipe, the at least one nozzle and / or transverse bore, wherein the at least one nozzle or

Querbohrung einem zu beölenden Bauteil zugeordnet ist. Gemäß der Erfindung weist die zumindest eine Düse bzw. Querbohrung jeweils eine Abtropfkante auf, über die das viskose, abtropfende Öl das zu beölende Bauteil des Getriebes erreichen kann.cross hole to oil one Component is assigned. According to the invention has the at least one nozzle or transverse bore in each case a drip edge over which the viscous, dripping oil to lubricated with oil Can achieve component of the transmission.

Gemäß einer bevorzugten Ausführungsform der Erfindung sind die Abtropfkanten an den Düsen bzw. an den Querbohrungen angegossen; alternativ dazu können die Abtropfkanten angeschweißt sein.According to one preferred embodiment of Invention are the drip edges on the nozzles or on the transverse bores a glove; Alternatively, you can the drip edges welded be.

Die Erfindung wird im folgenden anhand der beigefügten Figuren beispielhaft näher erläutert. Es zeigen:The The invention will be explained in more detail below with reference to the accompanying figures by way of example. Show it:

1: Eine schematische Darstellung einer erfindungsgemäßen Ausführungsform einer Einrichtung zur Beölung von Bauteilen eines Getriebes; und 1 : A schematic representation of an embodiment according to the invention of a device for lubricating components of a transmission; and

2: Eine schematische Darstellung einer weiteren erfindungsgemäßen Ausführungsform einer Einrichtung zur Beölung von Bauteilen eines Getriebes. 2 : A schematic representation of a further embodiment according to the invention of a device for lubricating components of a transmission.

Gemäß der Erfindung und bezugnehmend auf die 1 umfasst die Einrichtung 1 zur Beölung einer Verzahnung 2 eine mit einem Ölreservoir fluidtechnisch verbundene Einspritzleitung 3 für das Öl, wobei die Einspritzleitung 3 eine der Verzahnung 2 zugeordnete Düse 4 aufweist, wobei an dem der Verzahnung 2 zugewandten Ende der Düse 4 eine Abtropfkante 5 vorgesehen ist, so dass auch bei stark viskosem Öl das abtropfende Öl die Verzahnung erreichen kann bzw. auf die Verzahnung 2 geleitet wird.According to the invention and referring to the 1 includes the device 1 for lubrication of a toothing 2 an injection line fluidly connected to an oil reservoir 3 for the oil, with the injection line 3 one of the gearing 2 associated nozzle 4 having, wherein on the toothing 2 facing the end of the nozzle 4 a drip edge 5 is provided, so that even with highly viscous oil, the dripping oil can reach the teeth or on the teeth 2 is directed.

Da die Abtropfkante 5 wesentlich kleiner dimensioniert ist, als die Düse 4, kann deren der Verzahnung 2 zugewandtes Ende sehr nah an der Verzahnung 2 angeordnet sein, was eine temperaturunabhängige Beölung gewährleis tet. Bei warmen Öl erfolgt die Beölung der Verzahnung 2 im wesentlichen direkt über die Düse 4.Because the drip edge 5 is dimensioned much smaller than the nozzle 4 , can their teeth 2 facing end very close to the gearing 2 be arranged, which ensures a temperature-independent lubrication tet. With warm oil, the lubrication of the teeth takes place 2 essentially directly over the nozzle 4 ,

Bei dem in 2 gezeigten Beispiel ist die Abtropfkante 5 derart ausgebildet und angeordnet, dass das von der Verzahnung 2 abgeschleuderte Öl aufgefangen wird und auch im warmen Zustand des Öls auf die Verzahnung 2 zurücktropfen kann.At the in 2 The example shown is the drip edge 5 designed and arranged such that the of the teeth 2 spilled oil is caught and also in the warm state of the oil on the teeth 2 can drip back.

Durch die erfindungsgemäße Konzeption wird eine Einrichtung zur Beölung von Getriebebauteilen zur Verfügung gestellt, durch die die Beölung der Bauteile auch bei sehr viskosem Öl auf einfache und kostengünstige Weise sicherstellt wird. Des weiteren wird das Öl in vorteilhafter Weise schneller erwärmt.By the concept of the invention is a device for lubrication of transmission components available through which the oiling of the Components even with very viscous oil on simple and inexpensive Way is ensured. Furthermore, the oil is advantageously faster heated.
