Description

Das Patent 759,4 919 betrifft eine Innenbackenbremse, insbesondere für Kraftfahrzeuge, mit zwei hintereinander angeordneten Bremsbacken, auf deren vorderen am vorderen Ende die Verstellvorrichtung einwirkt, während sein hinteres Ende am vorderen Ende des hinteren, am Bremsschild gelagerten Bremsbackens angreift, und wobei der vordere Bremsbacken an seinem der Verstellvorrichtung abgekehrten Ende unmittelbar mit einem am Bremsschild gelagerten Schwenkarm gelenkig verbunden ist, der nach einem bestimmten Ausschlag das Backenende von der Bremstrommel abhebt.The patent 759.4 919 relates to an inner shoe brake, in particular for motor vehicles, with two brake shoes arranged one behind the other, on the front end of which the adjusting device acts, while its rear end acts on the front end of the rear brake shoe mounted on the brake plate, and the front Brake shoes is articulated at its end facing away from the adjustment device directly to a pivot arm mounted on the brake shield, which lifts the end of the shoe off the brake drum after a certain deflection.

Um die Größe der Servokraft beliebig verändern zu können, greift erfindungsgemäß der Lenker am Schwenkhebel entweder zwischen dessen beiden Endpunkten oder am freien Ende des Schwenkhebels an, wobei das Ende des vorderen Bremsbackens zwischen .den beiden Endpunkten des Schwenkhebels angreift. Es wird dadurch möglich, eine über- oder Untersetzung der vom vorderen Backen ausgeübten Kraft herbeizuführen. Erfindungsgemäß kann ferner die wirksame Länge des Schwenkarmes verstellbar gemacht werden, wobei zweckmäßig der Schwenkarm und der Lenker gelenkig miteinander verbunden sind. Einzelheiten sind .den folgenden Ausführungen zu entnehmen.In order to be able to change the size of the servo force as desired, the invention applies the handlebar on the pivot lever either between its two end points or on the free End of the pivot lever, the end of the front brake shoe between .den engages both end points of the pivot lever. This makes it possible to or to reduce the force exerted by the front jaw. According to the invention the effective length of the swivel arm can also be made adjustable, with expediently the swivel arm and the link are articulated to one another. details can be found in the following explanations.

Ausführungsbeispiele des Erfindungsgegenstandes sind in der Zeichnung dargestellt.Exemplary embodiments of the subject matter of the invention are shown in the drawing shown.

Am Bremsschild i (Abb. i). ist ein hydraulischer Bremszylinder :2 angeordnet, der bei Betätigen auf dien Backen 3 wirkt. Dieser Backen ist über einen nachstellbaren Lenker 4 mit dem Backen 5 verbunden, der an seinem freien Ende am Bolzen 6 ,des Bremsschildes gelagert ist. -Das Ende 7 des Backens 3 ist .mittels eines Schwenkarmes 8 am Bremsschild gelagert. Der Lenker 4 greift am Schwenkarm 8 zwischen dessen beiden Endpunkten an.On the brake plate i (Fig. I). is a hydraulic brake cylinder: 2 arranged, which acts on the jaws 3 when pressed. This baking is about one adjustable handlebar 4 connected to the jaw 5, at its free end on Bolt 6, of the brake shield is mounted. -The end 7 of the jaw 3 is .mittel a pivot arm 8 mounted on the brake shield. The handlebar 4 engages the swivel arm 8 between its two endpoints.

Ein anderes Ausführungsbeispiel- ist in Abb. 2 dargestellt, wobei der Lenker 4 am freien Ende eines Schwenkarmes 9 angelenkt ist und das freie Ende io des Backens 3 am Schwenkarm 9 zwischen dessen beiden Endpunkten angreift. Ein weiteres Ausführungsbeispiel ist in Abb. 3 dargestellt, das im wesentlichen dem der Abb. i entspricht, wobei jedoch die Nachstellung i i so am Schwenkarm 12 angeordnet .ist, daß außer der Länge des Lenkers 13 auch die wirksame Länge des Schwenkarmes i2 verändert wird. Die entsprechende Nachstellanordnung läßt sich auch an einer Ausführung gemäß Abb. 2 anbringen.Another embodiment is shown in Fig. 2, wherein the handlebar 4 is articulated at the free end of a pivot arm 9 and the free end io of the jaw 3 engages the pivot arm 9 between its two end points. A Another embodiment is shown in Fig. 3, which is essentially the corresponds to Fig. i, but the adjustment i i is arranged on the swivel arm 12 .is that in addition to the length of the link 13, the effective length of the swivel arm i2 is changed. The corresponding adjustment arrangement can also be used on a Attach the design as shown in Fig. 2.
