Description
Die Erfindung bezieht sich auf eine Bremsvorrichtung für Umlaufrädergetriebe mit zwei um i8o° zueinander versetzt angeordneten Bremseinrichtungen.The invention relates to a braking device for epicyclic gears with two braking devices offset from one another by 180 °.
Die Erfindung besteht darin, daß die Bremseinrichtungen aus zwei gleich langen Bändern bestehen, die nebeneinander auf der Bremstrommel liegen und durch eine gemeinsame Vorrichtung, z. B. eine Nockenscheibe oder einen Öldruckzylinder, betätigt werden. Die Betätigungshebel der Bremsbänder liegen in einer Ebene und in das Betätigungsgestänge des einen Bremsbandes ist ein bewegungsumkeIhrender Zwischentriebeingeschaltet.The invention consists in that the braking devices consist of two equal long strips that lie next to each other on the brake drum and through a common device, e.g. B. a cam disk or an oil pressure cylinder, be operated. The operating levers of the brake bands lie in one plane and A movement reversing of the intermediate drive is switched into the actuation linkage of the one brake band.
Durch die Erfindung wird ein Ausgleich der beim Bremsen auf die Bremsbänder ausgeübten und damit der für das Trommellager wirkenden Kräfte erzielt.The invention compensates for the braking on the brake bands exerted and thus achieved the forces acting for the drum bearing.
Die Zeichnung veranschaulicht ein Ausführungsbeispiel des Erfindungsgegenstandes.The drawing illustrates an embodiment of the subject matter of the invention.
Die Bremstrommel i wird von ,den beiden Bremsbändern 2 und 3 umspannt. Die Bremsbänder sind an zwei um 18o° zueinander versetzten Punkten 4 und 5 aufgehängt. Die Winkel a = ß bezeichnen jeweils den umspannten Bogen. Beide Bremsbänder wirken in demselben Sinn und werden in 'bekannter Weise durch Verschwenken ungleicharmiger Hebel 6, 7 an die Bremstrommel angelegt oder gelöst. Durch die gleichsinnige Wirkung der beiden Bremsbänder werden auf die Bremstrommel parallele, aber entgegengesetzt (im wesentlichen nach links und rechts) gerichtete Kräfte ausgeübt, welche sich in ihrer Wirkung auf das Trommellager aufheben. Zu diesem Zweck müssen auch die Anstellhebel 6, 7 für die Bremsen indem gleichen Sinne verschwenkt werden.. Zur Betätigung der Anstellhebel 6, 7 ist in dem dargestellten Fall ein Üldruckzylinder 8 vorgesehen, der durch eine zur Ölzufuhr dienende Ringnut 9 in zwei Teile io und i i unterteilt ist, in deren jedem ein Kolben 12 bzw. 13 spielt. Die Kolben sind über Pleuelstangen 14, 15 mit Betätigungshebeln 16, 17 verbunden, mittels deren die Anstellhebel 6, 7 verdreht werden. Bei der angenommenen Drehrichtung der Bremstrommel entgegen dem Uhrzeigersinn (Pfeil x) wird infolge der gegenläufigen Bewegung der Kolben 12, 13 der Anstellhebel6 ebenfalls entgegen dem Uhrzeigersinn verdreht, während der Hebel 7 in entgegengesetzter Richtung verschwenkt würde. Um trotzdem die geforderten gleichsinnigen Drehungen der Anstellhebel zu erzielen, wirkt der eine Betätigungshebel, z. B. 17, nicht unmittelbar auf den Anstellhebel 7, sondern durch Vermittlung eines Zwischentriebes in Form zweier ineinandergreifender und sich gegenläufig aufeinander abwälzender Zahnsegmente 18, i9 ein, welche an einander gegenÜberliegenden Stellen des Betätigungshebels 17 bzw. des Anstellhebels 7 vorgesehen sind.The brake drum i is spanned by the two brake bands 2 and 3. The braking bands are suspended from two points 4 and 5 offset from one another by 180 °. The angles a = ß each denote the arc that is spanned. Both brake bands work in the same sense and become more unevenly armed in the known way by pivoting Lever 6, 7 applied to the brake drum or released. Due to the similar effect of the two brake bands are parallel but opposite to the brake drum (essentially to the left and right) directed forces exerted, which are cancel in their effect on the drum bearing. To this end, the Adjustment levers 6, 7 for the brakes can be pivoted in the same sense In the case shown, actuation of the adjusting levers 6, 7 is an oil pressure cylinder 8 is provided, which by an annular groove 9 serving for the oil supply in two parts io and i i is subdivided, in each of which a piston 12 or 13 plays. The pistons are Connected via connecting rods 14, 15 to actuating levers 16, 17, by means of which the adjustment levers 6, 7 are rotated. With the assumed direction of rotation of the brake drum counterclockwise (arrow x) is due to the opposite movement of the Pistons 12, 13 of the adjusting lever 6 also rotated counterclockwise while the lever 7 would be pivoted in the opposite direction. To still get the requested to achieve rotations of the adjusting lever in the same direction, one operating lever acts z. B. 17, not directly on the adjustment lever 7, but through the intermediary of a Intermediate drive in the form of two interlocking and opposing one another rolling tooth segments 18, i9, which at mutually opposite points the actuating lever 17 and the adjusting lever 7 are provided.
Zum Zurückführen der Betätigungshebel 16, 17 in die Lösestellung sind Zugfedern 20, 21 einerseits an dem entsprechenden Hebel, andererseits am Bremszylinder 8 befestigt.To return the operating levers 16, 17 are in the release position Tension springs 20, 21 on the one hand on the corresponding lever, on the other hand on the brake cylinder 8 attached.
