Description
Die Erfindung bezieht sich auf eine Antriebsachse für ein Mobilfahrzeug nach der im Oberbegriff von Anspruch 1 näher definierten Art. The invention relates to a drive axle for a mobile vehicle according to the closer defined in the preamble of
Gattungsgemäße Antriebsachsen werden beispielsweise in Arbeitsmaschinen wie Landmaschinen oder Baumaschinen eingesetzt, um die Antriebsräder des Fahrzeugs anzutreiben. Häufig weisen diese Antriebsachsen Bremsen auf, wobei die Antriebsachse im Sinne einer Betriebsbremse bremsbar ist, indem Druckmittel auf einen Bremskolben wirkt. Generic drive axles are used, for example, in working machines such as agricultural machines or construction machines in order to drive the drive wheels of the vehicle. Frequently, these drive axles on brakes, wherein the drive axle in the sense of a service brake is braked by pressure acts on a brake piston.
Ebenso sind Getriebe bekannt, welche eine Parkbremse beinhalten, mittels welcher Zahnräder bremsbar sind, wenn die Bremse drucklos geschaltet ist. Likewise, transmissions are known which include a parking brake, by means of which gears are braked when the brake is depressurized.
Die
Der vorliegenden Erfindung liegt die Aufgabe zugrunde eine Antriebsachse für Mobilfahrzeuge, wie Landmaschinen und Baumaschinen, zu schaffen, welche eine Bremse aufweist, welche im Sinne einer Betriebsbremse und im Sinne einer Parkbremse auf einfache Weise benutzbar ist. The present invention has for its object to provide a drive axle for mobile vehicles, such as agricultural machinery and construction machinery, which has a brake which is usable in the sense of a service brake and in the sense of a parking brake in a simple manner.
Die Aufgabe wird mit einer auch die kennzeichnenden Merkmale des Hauptanspruchs aufweisenden gattungsgemäßen Antriebsachse gelöst. The object is achieved with a characterizing features of the main claim having generic drive axle.
Erfindungsgemäß weist die Antriebsachse eine Antriebswelle und ein Planetengetriebe auf, über welches eine Abtriebswelle ein Fahrzeugrad antreibt. Das Fahrzeugrad ist über eine Lamellenbremse bremsbar, wobei die Lamellenbremse über eine Betriebsbremse und eine Parkbremse bremsbar ist. According to the invention, the drive axle has a drive shaft and a planetary gear, via which an output shaft drives a vehicle wheel. The vehicle wheel can be braked via a multi-disc brake, wherein the multi-disc brake can be braked via a service brake and a parking brake.
Die Parkbremse ist so definiert, dass beim Drucklosschalten der Bremse diese mittels Federkraft im Schließsinne betätigt wird. Wird die Parkbremse bzw. der Kolben der Parkbremse mit Druck beaufschlagt, so bewegt sich der Kolben entgegen der Federkraft der Feder und die Bremse, vorzugsweise eine Lamellenbremse, wird im Öffnungssinne betätigt. Unter dem Begriff Betriebsbremse ist zu verstehen, dass die Bremse im Schließsinne betätigt wird, wenn die Bremse mit Druck beaufschlagt ist und die Bremse im Öffnungssinne betätigt ist, wenn die Bremse bzw. der Kolben der Bremse drucklos geschaltet ist. The parking brake is defined in such a way that when the brake is depressurized, it is actuated by spring force in the closing direction. If the parking brake or the piston of the parking brake is pressurized, then the piston moves against the spring force of the spring and the brake, preferably a multi-disc brake, is actuated in the opening direction. The term service brake is understood to mean that the brake is actuated in the closing direction when the brake is pressurized and the brake is actuated in the opening direction when the brake or the piston of the brake is depressurized.
Die Antriebsachse weist einen ersten Kolben auf, welcher der Parkbremse zugeordnet ist und weist einen zweiten Kolben auf, welcher der Betriebsbremse zugeordnet ist. The drive axle has a first piston, which is associated with the parking brake and has a second piston, which is associated with the service brake.
Der erste Kolben steht über Hebelelemente mit dem zweiten Kolben in Wirkverbindung, wobei die Hebelelemente die Kraft des ersten Kolbens auf den zweiten Kolben verstärken. Vorzugsweise sind die Hebelelemente in einem Käfig angeordnet, um diese ortsfest in der Antriebsachse zu halten. Der erste Kolben weist an seinem äußeren Durchmesser einen Vorsprung auf, an welchem mindestens ein Hebelelement anliegt, um die Kraft vom ersten Kolben über das Hebelelement auf den zweiten Kolben zu übertragen. Vorzugsweise sind die Hebelelemente gleichmäßig am Umfang des ersten Kolbens verteilt angeordnet. Auf den ersten Kolben wirkt eine Federkraft einer Feder, welche bei drucklosem ersten Kolben diesen auf die Hebelelemente drückt und diese die Kraft des ersten Kolbens auf den zweiten Kolben übertragen. Der zweite Kolben liegt an den Bremslamellen mittelbar oder unmittelbar an und überträgt somit die Kraft des ersten Kolbens auf die Bremslamellen, wodurch diese im Schließsinne im Sinne einer Parkbremsung betätigt werden. Der erste Kolben weist einen Kolbenraum auf, welcher mit Druckmittel mit Druck beaufschlagbar ist, wobei die Kraft, die dieses Druckmittel erzeugt gegen die Federkraft der Feder, welche auf den ersten Kolben wirkt, drückt, um den Kolben und somit die Bremse im Öffnungssinne zu betätigen. Der erste Kolben ist über weitere Federn mit dem zweiten Kolben verbunden, um den zweiten Kolben, wenn dieser drucklos geschaltet ist, vom Lamellenpaket der Lamellenbremse wegzuziehen, so dass die Lamellen frei drehen können. Der erste Kolben, die Feder, die Hebelelemente und der zweite Kolben sowie die Lamellen sind in einem einzigen Gehäuseteil angeordnet, wobei die Lamellen bzw. eine Druckplatte, auf welche die Lamellen drücken, benachbart zum Planetengetriebe angeordnet sind. The first piston is operatively connected to the second piston via lever members, the lever members amplifying the force of the first piston on the second piston. Preferably, the lever elements are arranged in a cage in order to hold these stationary in the drive axle. The first piston has at its outer diameter on a projection on which at least one lever element is applied to transmit the force from the first piston via the lever member to the second piston. Preferably, the lever elements are arranged distributed uniformly on the circumference of the first piston. On the first piston, a spring force of a spring, which presses with unpressurized first piston on the lever elements and these transmit the force of the first piston to the second piston. The second piston is applied directly or indirectly to the brake disks and thus transmits the force of the first piston to the brake disks, whereby they are actuated in the closing direction in the sense of a parking brake. The first piston has a piston chamber, which is pressurized with pressure medium, wherein the force that generates this pressure medium against the spring force of the spring, which acts on the first piston, presses to actuate the piston and thus the brake in the opening direction , The first piston is connected via further springs with the second piston to pull the second piston, when it is depressurized, away from the disk pack of the multi-disc brake, so that the fins can rotate freely. The first piston, the spring, the lever elements and the second piston and the lamellae are arranged in a single housing part, wherein the lamellae or a pressure plate on which press the lamellae are arranged adjacent to the planetary gear.
Der erste Kolben weist an seinem Umfang einen Vorsprung auf, welcher eine schiefe Ebene aufweist, über welche der erste Kolben entgegen der Federkraft der Feder im Öffnungssinne bewegt werden kann, indem vorzugsweise mit Gewinde versehene Bolzen im Gehäuseteil der Antriebsachse so verdreht werden können, dass diese auf die schiefe Ebene wirken und dadurch den Kolben im Öffnungssinne bewegen. The first piston has at its periphery a projection which has an inclined plane, via which the first piston can be moved in the direction of opening against the spring force of the spring by preferably threaded bolts in the housing part of the drive axle can be rotated so that this act on the inclined plane and thereby move the piston in the opening direction.
