Abstract

The brake lever (3) has a pivoting link (8), to which the brake cable is attached. A link roller (5) cooperates with a cam shoulder (7) on the brake lever support (10), to produce a controlled varying brake application. With the brake released, the cam shoulder lies near both the link axis (2) and a line joining the main lever and link pivot points (1,2). A line joining the link pivot point and cable attachment point (4) is approximately at right angles to the cable. ADVANTAGE - Reduced roller load.

Description

Die Erfindung hat die Aufgabe, eine mechanische Bremsbe­ tätigungsvorrichtung mit durch ein Kurvenrollengetriebe gesteuerter variabler Übersetzung zu schaffen, bei welcher die Belastung der Rolle zur Übersetzungssteuerung möglichst ge­ ring bleibt und eine minimale seitliche Auslenkung des Zug­ organs der Bremse gewährleistet ist.The invention has the task of a mechanical Bremsbe Actuating device with a cam roller gear to create controlled variable translation, in which the Load the role for translation control if possible ring remains and a minimal lateral deflection of the train organs of the brake is guaranteed.

Bekannt sind Vorrichtungen, bei denen am Spannhebel ein schwenkbarer Zusatzhebel angebracht ist, der einerseits über eine ortsfeste Steuer­ kurve geführt ist und an dem andererseits das Zugglied zur Bremse angreift.Devices are known in which a pivotable additional lever on the clamping lever is attached, on the one hand via a fixed tax curve is guided and on the other hand the tension member for Brake attacks.

Solche Vorrichtungen haben jedoch den Nachteil, daß die von der Rolle aufzunehmende Kraft bei den für die maximale Brems­ wirkung erforderlichen Kräften im Zugorgan so hohe Werte erreicht, daß die Rolle sehr teuer wird oder den geometrisch zur Übersetzungssteuerung möglichen Maximaldurchmesser über­ schreitet, so daß zwei Rollen erforderlich werden.However, such devices have the disadvantage that the the force to be absorbed by the roll for maximum braking forces required in the tension member so high values achieved that the role is very expensive or the geometric possible maximum diameter for translation control steps so that two roles are required.

Die Aufgabe wird durch Anwendung der Schutzmerkmale der Patentansprüche gelöst.The task is accomplished by applying the protective features of the Claims resolved.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung als feststellbaren Handbremshebel 3, welcher auf einem Tragstück 10 bei 1 um einen Zapfen schwenk- und fest­ stellbar ist und als Spannhebel 3 dient. Unterhalb der Schwenkachse 1 ist das Tragstück 10 mit einem Nocken 7 versehen, welcher in Wirkungsverbindung steht mit einer Rolle 5 an einem Zusatzhebel 8, der um einen Zapfen 2 am Spannhebel 3 gelagert ist.The drawing shows an embodiment of the invention as a lockable hand brake lever 3 , which is pivotable and fixed on a support 10 at 1 around a pin and serves as a tension lever 3 . Below the pivot axis 1 , the support piece 10 is provided with a cam 7 , which is in operative connection with a roller 5 on an additional lever 8 , which is mounted about a pin 2 on the clamping lever 3 .

Am Zusatzhebel 8 greift bei 4 das nicht gezeichnete Ver­ bindungsorgan zu den Radbremsen an, dessen Zugrichtung durch einen Pfeil gekennzeichnet ist.On the additional lever 8 , the connecting element (not shown) engages with the wheel brakes at 4, the direction of pull of which is indicated by an arrow.

In Lösestellung sind alle Teile mit ausgezogenen Linien ge­ zeichnet. Die strichpunktierten Linien zeigen die Endstellung der Vorrichtung, in welcher der Zusatzhebel 8 mit seiner Rolle 5 über den Nocken 7 geführt ist. Der Anschlußpunkt 4 hat sich dabei nahezu auf einer Geraden bewegt in Richtung des nicht gezeichneten Verbindungsorganes zu den Radbremsen. Die Rolle 5 ist in der Endlage des Zusatzhebels 8 ent­ lastet.In the release position, all parts are drawn with solid lines. The dash-dotted lines show the end position of the device, in which the additional lever 8 is guided with its roller 5 over the cam 7 . The connection point 4 has moved almost on a straight line in the direction of the connecting element, not shown, to the wheel brakes. The roller 5 is ent in the end position of the additional lever 8 .

Die Spannung einer Zugfeder 13 wirkt über einen Hebel 12 mit Rolle 11 in Verbindung mit einem Nocken 15 am Tragstück 10 derart, daß ihre Spannung die Betätigungskraft am Handbrems­ hebel 3 dann unterstützt, wenn nach Überwindung des Lüftspiels der Bremsanlage große Kraft am Zugorgan erforder­ lich ist.The tension of a tension spring 13 acts via a lever 12 with roller 11 in conjunction with a cam 15 on the support member 10 such that its tension supports the actuating force on the hand brake lever 3 when, after overcoming the air play of the brake system, great force is required on the tension member .
