Die Erfindung bezieht sich auf eine hydraulisch oder mechanisch von Hand betätigte Teilbelagscheibenbremse mit zwei aneinanderliegenden je eine Bremsbacke tragenden Rahmen, die entgegen der Kraft von die beiden Rahmen verbindenden Rückstellfedern gegen die Bremsscheibe gedrückt werden, wobei der eine von Konsolen des Bremsträgers getragene Rahmen mit seiner Öffnung die Bremsscheibe entlang einer Sekante umgreift, während der durch eine Kröpfung in die öffnung dieses einen Rahmens abgebogene Teil des anderen Rahmens mit seinen Seitenkanten an den Kanten des einen Rahmens geführt ist und die beiden Rahmen durch eine abgefederte Schraube miteinander verbunden sind, die ein Teil einer Nachstellvorrichtung für die auf der Seite der Betätigungsvorrichtungen liegenden Bremsbacke ist, nach Patent 1168 181. Hierbei ist in einer durch die beiden Rahmen gebildeten Öffnung die aus einem Zylinder und einem Kolben bestehende hydraulische Betätigungsvorrichtung angeordnet, in deren in einer Ebene liegende Nuten die Rahmen eingreifen.The invention relates to a hydraulically or mechanically manually operated partially-lined disc brake with two adjacent frames each carrying a brake shoe, which are contrary to the Force of return springs connecting the two frames are pressed against the brake disc, wherein the one supported by brackets of the brake carrier frame with its opening the brake disc embraced along a secant, while by a crank in the opening of this one frame bent part of the other frame out with its side edges on the edges of one frame is and the two frames are connected to each other by a spring-loaded screw that part of an adjustment device for the brake shoe located on the side of the actuation devices is, according to patent 1168 181. Here is in an opening formed by the two frames a cylinder and a piston existing hydraulic actuator arranged in whose grooves in one plane engage the frame.

Bei einer derartigen Bremse bewirkt die Nachstellvorrichtung ein vorbestimmtes Bremslüftspiel lediglich für die eine Bremsbacke. Die andere schleift in der Losestellung drucklos an der Bremsscheibe. Das Schleifen von Bremsbelägen an der Bremsscheibe hat den schnellen Verschleiß, das Auftreten klappernder und klirrender Geräusche und eine Wärmeentwicklung zur Folge. Der schleifende Belag verschleißt schneller als der, der sich von der Scheibe löst und muß daher früher bzw. häufiger ausgewechselt werden.In the case of a brake of this type, the adjusting device merely effects a predetermined brake clearance for one brake shoe. The other rubs against the brake disc without pressure in the loose position. That Grinding of brake pads on the brake disc has the rapid wear, the occurrence of rattling and clanking noises and heat generation. The abrasive surface wears out faster than the one that comes off the disc and must therefore be replaced earlier or more frequently will.

Erfindungsgemäß wird zur Beseitgung dieses Nachteils vorgeschlagen, daß auch zur Nachstellung der auf der den Betätigungsvorrichtungen abgelegenen Seite der Bremsscheibe liegenden Bremsbacke die Konsolen des Bremsträgers und den die Bremsbacke tragenden Rahmen durchgreifende, abgefederte Schrauben dienen, die ein Teil einer an sich bekannten Nachstellvorrichtung sind, die erst wirksam ist, wenn der axial federnde Bremsträger beim Bremsen nach Überwindung des Lüftspiels an einem feststehenden Anschlag anliegt.According to the invention it is proposed to eliminate this disadvantage that also to readjust the on the side of the brake disc remote from the actuation devices, the Brackets of the brake carrier and the frame carrying the brake shoe through, spring-loaded Serve screws that are part of a known adjusting device that is only effective, if the axially resilient brake carrier when braking after overcoming the clearance on a stationary one Stop is present.

Dabei kann das Langloch der Nachstellvorrichtung entweder in dem Rahmen oder in der Konsole angeordnet sein.The elongated hole of the adjusting device can either be in the frame or in the console be arranged.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt, die einen Schnitt durch die Bremse in der Ebene der Nachstellvorrichtung zeigt.An embodiment of the invention is shown in the drawing, which is a section through the Brake shows in the plane of the adjuster.

Die Bremsscheibe 1 wird von dem Rahmen 2 umfaßt, der die Bremsbacke 3,4 hält. Der Bremsträger 5 Hydraulisch oder mechanisch von Hand betätigte TeilbelagscheibenbremseThe brake disc 1 is encompassed by the frame 2, which holds the brake shoe 3, 4.

ist mit den abgewinkelten Konsolen 6 versehen, die in diesem Fall mit einer Bohrung zur Aufnahme der Schraube 7 versehen sind. 8 ist ein Langloch im Rahmen 2, das genügend Raum für die Nachstellbewegung bei Verschleiß bietet. Die Schraube 7 drückt mit der Kraft der Feder 9 über die Scheiben 10 und 11, die Reibscheibe 12, den Rahmen 2 und die Konsolen 6 aneinander. Der Anschlag 13 ist an einem nicht dargestellten ruhenden Teil der Maschine befestigt, zu deren Abbremsung die Bremse dient.is provided with the angled brackets 6, which are provided with a hole for receiving the screw 7 in this case. 8 is an elongated hole in the frame 2, which offers enough space for the readjustment movement in the event of wear. The screw 7 presses with the force of the spring 9 via the disks 10 and 11, the friction disk 12, the frame 2 and the brackets 6 against one another. The stop 13 is attached to a stationary part of the machine, not shown, which the brake is used to brake.

Da im Lösezustand der Bremse zwischen dem Bremsträger 5 und dem Anschlag 13 ein Abstand X besteht, der dem Lüftspiel entspricht, wird beim Verschieben der beiden Rahmen gegeneinander zunächst eine elastische Federung des Bremsträgers erreicht, der sich an den Anschlag 13 anlegt und damit das Lüftspiel aufhebt. Die Feder 9 ist so ausgelegt, daß die Reibung zwischen der Reibscheibe 12, dem Rahmen 2 und der Konsole 6 bei der federnden Bewegung des Bremsträgers erst nach dessen Auftreffen auf den Anschlag 13 überwunden wird. Erst dann kann der Rahmen 2 auf der Konsole 6 gleiten und die Bremsbacke 3, 4 in bremsenden Eingriff mit der Scheibe 1 bringen. Der Verschleiß des Bremsbelags 4 wird während des Bremsens ausgeglichen.Since in the released state of the brake between the brake carrier 5 and the stop 13 there is a distance X which corresponds to the clearance, when the two frames are moved against each other, an elastic suspension of the brake carrier is first achieved, which rests against the stop 13 and thus eliminates the clearance . The spring 9 is designed so that the friction between the friction disk 12, the frame 2 and the bracket 6 during the resilient movement of the brake carrier is only overcome after it has hit the stop 13. Only then can the frame 2 slide on the bracket 6 and bring the brake shoe 3, 4 into braking engagement with the disc 1. The wear of the brake lining 4 is compensated for during braking.

Nach dem Lösen der Bremse federt der Bremsträger 5 um das Maß X in Richtung auf die ScheibeAfter releasing the brake, the brake carrier 5 springs by the amount X in the direction of the disc
