Description

. Es ist bekannt, bei. Scheibenbremsen die Bremswirkung durch Aufrollen von Kugeln, die in kegelförmigen Ausnehmungen von Formstücken zwischen den beiden. Bremsscheiben liegen, zu erzielen. Damit die Kugeln aufrollen können, ist eine Verschiebung .der beiden Bremsscheiben gegeneinander notwendig: Dies geschah bisher durch einen Betätigungshebel, der unmittelbar auf den Bremsscheiben angeordnet war.. It is known at. Disc brakes the braking effect by rolling up of balls that are in conical recesses of fittings between the two. Brake discs lie to achieve. So that the balls can roll up, there is a shift . of the two brake discs against each other: This was previously done by a Operating lever, which was arranged directly on the brake discs.

Erfindungsgemäß wird eine Bremsbetätigung vorgeschlagen, bei der die beiden Bremsscheiben mittels eines Keilhebels gegeneinander verschoben werden. Dieser Keilhebel kann je nach seiner Bauart durch Druck- oder Zugbewegung betätigt werden.According to the invention, a brake actuation is proposed in which the both brake disks are moved against each other by means of a wedge lever. This Wedge lever can be operated by pushing or pulling, depending on its design.

Infolge des Wegfalls der bisherigen Gelenkhebel bei den-bekannten Scheibenbremsen wird durch den erfindungsgemäßen Keilhebel eine gleichmäßigere Bremskraft erreicht; was für den gesamten Bremsvorgang vorteilhaft ist. Außerdem nimmt der Keilhebel gemäß der Erfindung einen sehr geringen Platz in Anspruch.As a result of the elimination of the previous articulated lever in the-known Disc brakes have a more uniform braking force thanks to the wedge lever according to the invention achieved; which is advantageous for the entire braking process. Besides, he takes Wedge levers according to the invention take up very little space.

Die Zeichnung veranschaulicht den Erfindungs= gegenstand in zwei Ausführungsformen, und zwar wird in Fig. i der erfindungsgemäße Keilhebel durch Druckbewegung und in Fig.2 durch Zugbewegung betätigt.The drawing illustrates the invention = subject in two embodiments, namely in Fig. i the wedge lever according to the invention by pressure movement and in Fig. 2 actuated by pulling movement.

Auf :der Bremsscheibe r mit dem Bremsbelag 2 ist eiirre Rolle 3 und auf der Bremsscheibe q. mit dem Bremsbelag 5 eine Rolle 6 befestigt. Zwischen beiden Rollen bewegt sich der Keilhebel 7, welcher gabelförmig den Zwischenhebel 8 umfaß.t und durch den Stift g festgehalten wird. Die Betätigungskraft- wird über, den Betätigungshebel 1o, der durch den -Bolzen i 1' mit dem feststehenden Bremsflansch 12 verbunden ist, und über den Zwischenhebel 8 auf den Keilhebel 7 übertragen und drückt bzw. zieht diesen (s. Fig. i bzw. 2) zwischen die auf den Bremsscheiben sitzenden Rollen 3 und 6, so däß die Bremsscheiben gegeneinander verschoben, die Kugeln 13 in den kegelförmigen Ausnehmungen 1¢ der Formstücke 15 aufrollen und die Bremsscheiben 1 und q. gegen die rotierenden Teile gedrückt werden.On: the brake disc r with the brake lining 2 is a roller 3 and on the brake disc q. a roller 6 is attached to the brake lining 5. Between the two The wedge lever 7, which comprises the intermediate lever 8 in the form of a fork, moves rolling and is held in place by the pin g. The actuation force is via, the actuation lever 1o, which is connected to the fixed brake flange 12 by the bolt i 1 ', and transmitted via the intermediate lever 8 to the wedge lever 7 and pushes or pulls these (see Fig. i and 2) between the rollers 3 seated on the brake disks and 6, so that the brake disks are displaced against one another, the balls 13 in the conical Roll up the recesses 1 ¢ of the fittings 15 and the brake disks 1 and q. against the rotating parts are pressed.
