Abstract
Description
Die vorliegende Erfindung betrifft eine ölgekühlte Lamellenbremse für ein Kraftfahrzeug, gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to an oil-cooled multi-disc brake for a motor vehicle, according to the generic term of claim 1
Derartige
Lamellenbremsen können
nach dem Stand der Technik u.a. als Fahrzeugbremsen in zumindest
eine Achse eines Fahrzeugs integriert werden. Sie werden üblicherweise
in Antriebsachsen von elektromotorisch angetriebenen Fahrzeugen
sowie in Achsen von Traktoren und Arbeitsmaschinen integriert. Eine
in eine Antriebsachse integrierte ölgekühlte Lamellenbremse ist beispielsweise
im Rahmen der
Die für den Betrieb erforderliche Innenschmierung und Kühlung von Lamellenkupplungen und Lamellenbremsen wird nach dem Stand der Technik dadurch gewährleistet, dass Schmieröl über eine Gehäusebohrung zu einer gelagerten Bremswelle geleitet wird, die wiederum Ölbohrungen aufweist, so dass das Öl an den entsprechenden Stellen durch Austrittsbohrungen den Bremslamellen zuführbar ist. Bei diesen Konstruktionen ist es notwendig, dass die Brems- bzw. Lamellenträgerwelle gelagert ist; ferner ist eine Abdichtung der Ölübergabestelle vom Gehäuse zur Welle erforderlich, was in der Regel mittels Kolben-Rechteckringen erfolgt.The for the Operation required internal lubrication and cooling of multi-plate clutches and Multi-disc brakes are ensured by the prior art, that lubricating oil over a housing bore is directed to a mounted brake shaft, which in turn oil holes so that the oil at the appropriate points through exit holes the brake plates supplied is. In these constructions, it is necessary that the brake or plate carrier shaft is stored; Furthermore, a seal of the oil transfer point from the housing to Wave required, which is usually by means of piston rectangular rings he follows.
Bei Konstruktionen, bei denen die Bremswelle nicht gelagert ist, kann die beschriebene Schmierölzufuhr in nachteiliger Weise nicht umgesetzt werden.at Constructions in which the brake shaft is not stored, can the described lubricating oil supply not be implemented disadvantageously.
Aus
der
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine ölgekühlte Lamellenbremse für ein Kraftfahrzeug anzugeben, bei der keine Lagerung der Bremswelle sowie keine drehenden Dichtelemente für die Schmierölzuführung benötigt werden. Zudem soll eine sehr große Schmierölmenge in die Bremse leitbar sein und eine effektive Kühlung gewährleistet werden. Ein weiteres Ziel der Erfindung ist es, die Verwendung einer flexiblen Leitung für das Schmieröl zu vermeiden.Of the The present invention is based on the object, an oil-cooled multi-disc brake for a motor vehicle specify when no bearing of the brake shaft and no rotating Sealing elements for the lubricating oil supply are needed. moreover should be a very big one Amount of lubricating oil be guided into the brake and effective cooling can be ensured. Another one The aim of the invention is the use of a flexible conduit for the lubricating oil to avoid.
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 ölgekühlte Lamellenbremse vorgeschlagen, umfassend ein Lamellenpaket mit Innen- und Außenlamellen, eine Bremsträgerwelle und einen Aktuator zum Betätigen der Bremse, bei der der Aktuator ein radiales Langloch aufweist, durch das ein Rohr geführt ist, mittels dessen das Schmieröl bis an die Bremsträgerwelle leitbar ist. Vorzugsweise ist das Langloch derart angeordnet, dass das Rohr zwischen Aktuator und Bremsträgerwelle gerade ausgeführt sein kann.Therefore becomes an oil-cooled multi-disc brake proposed, comprising a disk set with inner and outer disks, a brake carrier shaft and an actuator for actuating the brake, in which the actuator has a radial slot through that led a pipe is, by means of which the lubricating oil to the brake carrier shaft is conductive. Preferably, the slot is arranged such that the Pipe between actuator and brake carrier shaft be straight can.
Gemäß der Erfindung wird das Rohr starr ausgeführt und kann aus Stahl hergestellt sein. Ferner ist das Rohr im Bremsgehäuse verschraubt; in vorteilhafter Weise ist das Langloch derart dimensioniert, dass in allen Betriebszuständen des Fahrzeugs ein ausreichendes Spiel zwischen Aktuator und Rohr besteht.According to the invention the pipe is rigid and can be made of steel. Furthermore, the tube is screwed in the brake housing; Advantageously, the slot is dimensioned such that in all operating states the vehicle is a sufficient clearance between actuator and pipe.
Im Rahmen einer besonders vorteilhaften Ausführungsform der Erfindung wird vorgeschlagen, den Aktuator als Kugelrampenaktuator auszubilden und in jeder der Aktuatorhälften eine Aussparung in der Form eines halben Langloches im Gussteil vorzusehen, so dass sich im montierten Zustand der Lamellenbremse ein ganzes Langloch ergibt, durch das das Rohr führbar ist. Hierbei ist das Langloch derart dimensioniert, dass bei maximalen Schwenkbewegungen der Aktuatorhälften ausreichend Freiraum zum Rohr bestehen bleibt.in the Frame of a particularly advantageous embodiment of the invention is proposed to form the actuator as Kugelrampenaktuator and in each of the actuator halves a recess in the form of half an elongated hole in the casting provide, so that in the mounted state of the multi-disc brake a whole slot results, through which the pipe is feasible. Here it is Slot sized so that at maximum pivoting movements the actuator halves sufficient space remains to the pipe.
Als besonders vorteilhaft erweist es sich, wenn die Langlochhälften im Gussrohteil eingearbeitet sind, da dadurch eine aufwendige und kostenintensive mechanische Bearbeitung entfällt.When it proves to be particularly advantageous if the slot halves in the Cast ingot are incorporated, as a result, a complex and costly Mechanical processing is eliminated.
Durch die erfindungsgemäße Konzeption kann eine sehr große Kühlölmenge (in Abhängigkeit vom Rohrquerschnitt) ins Innere der Bremse geleitet werden, welche dann durch die Fliehkräfte verteilt wird, so dass eine optimale Kühlung gewährleistet wird.By the concept of the invention can a very big one Cooling oil quantity (in Dependency on Pipe cross-section) are passed into the interior of the brake, which then through the centrifugal forces is distributed so that optimum cooling is ensured.
Die Erfindung wird im Folgenden anhand der beigefügten Figuren beispielhaft näher erläutert. Es zeigen:The invention will be described below with reference to the attached figures explained in more detail by way of example. Show it:
