Abstract
Description
Die Erfindung betrifft ein Ausgleichsgetriebe nach der im Oberbegriff von Anspruch 1 näher definierten Art.The The invention relates to a differential gear according to the preamble Of claim 1 further defined type.
Die
Der vorliegenden Erfindung liegt die Aufgabe zugrunde ein Ausgleichsgetriebe mit einer Sperre zu schaffen, welches in axialer Richtung kompakt baut.Of the present invention, the object is a differential gear to provide a barrier which is compact in the axial direction builds.
Die Aufgabe wird mit einem auch die kennzeichnenden Merkmale des Hauptanspruchs aufweisenden gattungsgemäßen Ausgleichsgetriebe gelöst.The Task is with a also the characterizing features of the main claim having generic differential gear solved.
Erfindungsgemäß weist das Ausgleichsgetriebe eine Sperre zum Sperren der Ausgleichswirkung auf, welche Lamellen aufweist, wobei die Lamellen in drehfester Verbindung mit einem Achskegelrad stehen. Die Lamellen können direkt mit dem Achskegelrad verbunden sein, es besteht jedoch auch die Möglichkeit die Lamellen über einen mit dem Achskegelrad drehfest verbundenen Lamellenträger zu haltern. Eine Betätigungseinrichtung weist einen Betätigungskolben auf, wobei die Betätigungseinrichtung hydraulisch oder elektromechanisch betätigt sein kann und wobei der Betätigungskolben auf der einen Seite des Ausgleichsgetriebes und die Lamellen auf der anderen Seite des Ausgleichsgetriebes angeordnet sind, wodurch ein Ausgleichskegelrad zwischen dem Betätigungskolben und den Lamellen angeordnet ist. Die Kraftübertragung vom Kolben zu den Lamellen kann über mindestens einen Bolzen oder mehrere Bolzen, welche gleichmäßig am Umfang verteilt sind, erfolgen, wobei innerhalb des Bolzens eine Feder angeordnet sein kann, um den Kolben bei Nichtbetätigung in seine Ausgangslage zurückzudrücken. Vorzugsweise ist der Bolzen in einer Öffnung innerhalb des Differenzialkorbes angeordnet, wobei die Öffnung radial unterhalb des mit dem Differenzialkorb verbundenen Tellerrades angeordnet ist. Der Differenzialkorb ist über zwei Lagerstellen in einem Gehäuse gelagert, wobei innerhalb dieses Gehäuses der Kolben angeordnet ist. Vorzugsweise ist der Kolben radial außerhalb einer dieser Lagerstellen angeordnet. In einer weiteren Ausgestaltungsform bei hydraulischer Betätigung ist der Kolben über eine Membrandichtung von der Hydraulikflüssigkeit getrennt, wobei die Membrandichtung innerhalb des Gehäuses angeordnet ist und mit dem Gehäuse einen Kolbenraum bildet.According to the invention the differential gear a lock to block the balancing effect on, which has lamellae, wherein the lamellae in non-rotatable Connection with a bevel gear stand. The slats can be connected directly to the Achskegelrad, but it is also the possibility of slats over with the Achskegelrad rotatably connected plate carrier to support. An actuating device has an actuating piston on, wherein the actuator hydraulically or can be actuated electromechanically and wherein the actuating piston on one side of the differential and the slats on the other side of the differential gear are arranged, whereby a Ausgleichkekegelrad between the actuating piston and the slats is arranged. The power transmission from the piston to the slats can be via at least one bolt or several bolts, which distribute evenly around the circumference are carried out, wherein disposed within the bolt, a spring can be to the piston when not operating in its initial position push back. Preferably, the bolt is in an opening arranged inside the differential cage, the opening radially below the ring gear connected to the differential cage is arranged. The differential basket is over two storage locations stored in a housing, being inside this housing the piston is arranged. Preferably, the piston is radially outward one of these bearings arranged. In a further embodiment in hydraulic operation, the piston is over a membrane seal is separated from the hydraulic fluid, wherein the membrane seal is disposed within the housing is and forms a piston chamber with the housing.
In einer weiteren Ausgestaltungsform der Erfindung sind die Lamellen über einen Lamellenträger drehfest mit dem Achskegelrad verbunden, wobei der Lamellenträger radiale und axiale Bohrungen aufweist, um Schmiermittel zu den Lamellen zu bringen. Vorzugsweise weist der Differenzialkorb unterhalb der Lagerstelle im Bereich des Achskegelrades und des Lamellenträgers eine Spiralnut auf, über welche Schmiermittel zu den Bohrungen im Lamellenträger gefördert wird. Vorzugsweise ist die Schmiernut spiralförmig ausgeführt.In In another embodiment of the invention, the slats are over a plate carrier rotatably connected to the axle bevel gear, wherein the disk carrier has radial and axial bores, to bring lubricant to the fins. Preferably the differential cage below the bearing in the area of the Achskegelrades and of the disk carrier on a spiral groove, over which Lubricant conveyed to the holes in the plate carrier becomes. Preferably, the lubrication groove is spiral.
