Abstract
Description
Die Erfindung betrifft eine Lamellenbremse nach der im Oberbegriff von Anspruch 1 näher definierten Art.The The invention relates to a multi-disc brake according to the preamble of Claim 1 closer defined type.
Bei Relativdrehzahlen von Außenlamellen zu Innenlamellen und gleichzeitigem Übertragen von Drehmoment entsteht Reibungswärme bei den Lamellen. Durch Zuführen von Kühlöl kann diese Reibungswärme abgeführt werden. In geöffnetem Zustand, d. h. ohne Übertragung von Drehmoment über die Lamellen, verschlechtert sich der Wirkungsgrad, wenn die Lamellen mit Differenzdrehzahl im Schmiermittel betrieben werden, da hierbei die sogenannten Panschverluste entstehen.at Relative speeds of outer disks to inner fins and simultaneous transfer of torque arises frictional heat at the slats. By feeding of cooling oil can do this frictional heat dissipated become. In open State, d. H. without transmission of torque over the Slats, the efficiency deteriorates when the slats operated with differential speed in the lubricant, since this the so-called panschverluste emerge.
Die
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Lamellenbremse zu schaffen, welche gezielt gekühlt werden kann und im geöffneten Zustand einen guten Wirkungsgrad aufweist.Of the present invention is based on the object, a multi-disc brake to create which cooled specifically can be and in the open Condition has a good efficiency.
Die der Erfindung zugrunde liegende Aufgabe wird durch eine, auch die kennzeichnenden Merkmale des Hauptanspruchs aufweisende, gattungsgemäße Lamellenbremse gelöst.The The object underlying the invention is by one, also the Characteristic features of the main claim having, generic multi-disc brake solved.
Erfindungsgemäß weist die Lamellenbremse stehende äußere Lamellen und drehende innere Lamellen auf sowie einen Kolben, welcher die Lamellenbremse im Schließsinne und Öffnungssinne betätigt. Der Kolben steht mit einem weiteren Kolben in Wirkverbindung, wodurch der weitere Kolben bei im Öffnungssinne betätigter Lamellenbremse einen Kühlmittelstrom verschließt und bei im Schließsinne betätigter Lamellenbreme den Kühlmittelstrom öffnet. Der weitere Kolben ist so angeordnet, dass der Kühlmittelstrom zu den äußeren Lamellen strömt und von dort die Lamellenbremse in Richtung der inneren Lamellen durchströmt. Dadurch wird erreicht, dass auch im geschlossenen Zustand der Lamellenbreme diese effektiv gekühlt wird, da im Gegensatz zur Lamellenkupplung die Innen- und die Außenlamellen im geschlossenen Zustand nicht rotieren, wodurch eine Durchströmung über Fliehkräfte nicht stattfindet. Der weitere Kolben zur Steuerung des Kühlmittelstroms ist im Bereich der Lamellenbremse angeordnet, wobei dieser Kolben, da er nicht koaxial zum Kolben zur Betätigung der Lamellenbremse angeordnet ist, einen geringen Durchmesser aufweisen kann, wodurch Dichtmittel nicht notwendig sind und eine sogenannte Spaltdichtung ausreicht.According to the invention the lamellar brake standing outer lamellae and rotating inner fins on and a piston which the Multi-disc brake in closing direction and opening senses actuated. The piston is in operative connection with another piston, whereby the other piston in the opening direction actuated Multi-disc brake a coolant flow closes and in the direction of closing operated lamellae opens the coolant flow. Of the another piston is arranged so that the coolant flow to the outer fins flows and from there the multi-disc brake in the direction of the inner fins flows through. This ensures that even in the closed state of the disk brake this effectively cooled is, as opposed to the multi-plate clutch, the inner and outer disks do not rotate in the closed state, whereby a flow through centrifugal forces not takes place. The other piston for controlling the coolant flow is arranged in the region of the multi-disc brake, said piston since it is not arranged coaxially with the piston for actuating the multi-disc brake is, may have a small diameter, creating sealant are not necessary and a so-called gap seal sufficient.
In einer weiteren Ausgestaltungsform können mehrere dieser weiteren Kolben zur Steuerung des Kühlmittelstroms gleichmäßig verteilt im Bereich der Lamellen angeordnet sein, wodurch ein gleichmäßiges Zuführen des Kühlmittelstroms stattfindet.In In another embodiment, several of these further Piston for controlling the coolant flow equally distributed be arranged in the region of the slats, whereby a uniform feeding of the Coolant flow takes place.
In einer weiteren Ausgestaltungsform weist die Lamellenbremse einen Entleerungskolben auf, welcher vorzugsweise im unteren Bereich der Lamellenbremse angeordnet ist und bei im Öffnungssinne betätigter Lamellenbremse so betätigt wird, dass das Kühlmittel, welches sich im Bereich der Lamellenbremse befindet, durch einen Auslaß entweichen kann, wodurch der Wirkungsgrad der Lamellenbremse im geöffneten Zustand verbessert wird.In In another embodiment, the multi-disc brake has a Emptying piston, which preferably in the lower part of Lamella brake is arranged and in the opening direction operated multi-plate brake so actuated will that the coolant, which is located in the area of the multi-disc brake, by a Outlet can escape, whereby the efficiency of the multi-disc brake in the open Condition is improved.
