Abstract
Description
Die vorliegende Erfindung betrifft eine Lamellenbremse gemäß dem Oberbegriff des Patentanspruchs 1. Des weiteren betrifft die Erfindung ein Verfahren zur Schmierung bzw. Kühlung einer nassen Lamellenbremse.The present invention relates to a multi-disc brake according to the preamble of claim 1. Furthermore, the invention relates to a method for lubrication or cooling a wet multi-disc brake.
Nasse Labellenbremsen werden nach dem Stand der Technik in Getrieben, wie beispielsweise Lastschaltgetriebe, Schleppergetriebe oder Automatgetriebe, zur Schaltung der Gangstufen eingesetzt. Sie weisen eine bessere Schaltqualität als Bandbremsen auf, da der Bremsvorgang sehr fein dosierbar ist.Wet labelle brakes are after the state of the art in transmissions, such as powershift transmissions, Tractor gearbox or automatic gearbox, for switching the gear stages used. They have a better shift quality than band brakes because the Braking is very finely metered.
Nach dem Stand der Technik erfolgt die Schmierung von nassen Lamellenbremsen üblicherweise von außen, beispielsweise durch Kühlölzuführung über ein Sprührohr von oben; des weiteren wird eine zusätzliche Schmierung durch Eintauchen des umlaufenden Lamellenpakets in einen Ölsumpf erzielt. Bei einigen Getriebeanordnungen kann eine zusätzliche Schmierölzuführung von innen durch die Abriebswelle erfolgen.According to the state of the art the lubrication of wet multi-disc brakes usually from the outside, for example by supplying cooling oil via a lance from above; furthermore additional lubrication by immersion of the rotating plate pack in an oil sump. With some Gear arrangements can have an additional supply of lubricating oil done inside by the abrasion shaft.
Die
Es kann jedoch Situationen geben, insbesondere bei Fahrzeugen mit hohen Lastdaten bzw. mit hoher Fahrzeugmasse, bei denen die Kühlung nicht ausreichend ist, sodass es zu sehr hohen Temperaturen im Lamellenpaket kommen kann, was eine thermische Zerstörung des Reibbelagmaterials zur Folge haben kann.However, there can be situations especially for vehicles with high load data or with high vehicle mass, where the cooling is not is sufficient so that there are very high temperatures in the plate pack can come what a thermal destruction of the friction lining material can result.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine nasse Lamellenbremse anzugeben, welche die Nachteile des Standes der Technik vermeidet. Insbesondere soll in jeder Situation eine effektive Kühlung gewährleistet werden. Zudem soll im Rahmen der vorliegenden Erfindung ein Verfahren zur Schmierung bzw. Kühlung einer nassen Lamellenbremse angegeben werden.The present invention lies the task of specifying a wet multi-disc brake, which avoids the disadvantages of the prior art. In particular, should effective cooling can be guaranteed in every situation. In addition, should in the context of the present invention, a method for lubrication or cooling a wet multi-disc brake.
Diese Aufgabe wird für eine Lamellenbremse durch die Merkmale des Patentanspruchs 1 gelöst. Das Verfahren zur Schmierung bzw. Kühlung einer nassen Lamellenbremse ist Gegenstand des Patentanspruchs 7. Weitere Ausgestaltungen und Vorteile gehen aus den entsprechenden Unteransprüchen hervor.This task is accomplished for a multi-disc brake solved the features of claim 1. The procedure for lubrication or cooling A wet multi-disc brake is the subject of claim 7. Further configurations and advantages go from the corresponding Sub-claims emerge.
Demnach wird vorgeschlagen, eine nasse Lamellenbremse derart auszubilden, dass eine Innenschmierung durch den Aktivator der Lamellenbremse hindurch ins Innere des Aktivators erfolgt. Das auf diese Weise der Bremse zugeführte Öl verlässt erfindungsgemäß über die durch die Rotation entstehende Fliehkraft durch die Belagsstruktur den Innenraum der Bremse, was in einer besseren Öldurchflutung der Reibbeläge resultiert. Dies kann in vorteilhafter Weise auch bei Situationen nachträglich angewendet werden, bei denen eine Schmierung von innen heraus durch die Welle konstruktiv nicht bzw. nicht mehr möglich ist.Accordingly, it is proposed to to design wet multi-disc brakes such that internal lubrication through the activator of the multi-disc brake into the inside of the activator he follows. According to the invention, the oil supplied to the brake in this way leaves via the centrifugal force caused by the rotation through the covering structure the interior of the brake, which results in better oil flow in the friction linings. This can advantageously also be applied retrospectively in situations be lubricated from the inside out by the shaft constructively not or no longer possible.
