Description

Die Erfindung bezieht sich auf Bremseinrichtungen, insbesondere Backenbremsen für Schienenräder. Sie steEt sich insbesondere die Aufgabe, einen luchtmetallischen Brems-S belag von hohem Reibwert, der bei Zusammenwirken mit einer glatten metallischen •Reibfläche eine außerordentlich große Bremswirkung zu erzielen vermag, davor zu schützen, daß die Reibfläche, mit der der Bremsbelag zusammenwirkt, rauh wird und alsdann einen schnellen Verschleiß des Bremsbelages herbeiführt. Zu diesem Zwecke werden gemäß der Erfindung in der Bewegungsrichtung des zu bremsenden Teiles vor der Bremsbacke Reinigungsvorrichtungen vorgesehen, die vor der Bremsbacke zum Anliegen an die Bremsfläche kommen. Diese Reinigungsvorrichtungen haben zweckmäßig einen aus einem Schleifmittel bestehenden Reibteil. Sie sind beispielsweise derart angeordnet oder ausgestaltet, daß sie sich nur mit leichtem Druck an die Bremsfläche anlegen, also selbst keine wesentliche Bremswirkung ausüben. Dies kann dadurch geschehen, daß die Reinigungs-Vorrichtungen federnd nachgiebig in ihrem Halter angeordnet sind, so daß sie beim Auftreffen auf die Bremsfläche nachgeben und der etwa zum Anliegen kommenden Bremsbacke die eigentliche Bremsarbeit überlassen.The invention relates to braking devices, in particular shoe brakes for Rail wheels. In particular, it has set itself the task of creating a luminous metallic brake-S coating with a high coefficient of friction which, when combined with a smooth metallic friction surface, • has an extraordinarily large braking effect able to achieve to protect against that the friction surface with which the brake lining cooperates, becomes rough and then causes rapid wear of the brake lining. For this purpose, according to the invention, in the direction of movement of the part to be braked in front of the brake shoe Cleaning devices are provided, which are in front of the brake shoe to rest against the braking surface come. These cleaning devices expediently have a friction part consisting of an abrasive. they are for example, arranged or designed so that they can only be removed with light pressure Apply to the braking surface, i.e. do not exert any significant braking effect yourself. this can be done in that the cleaning devices are resilient in their Holders are arranged so that they yield when they hit the braking surface and Leave the actual braking work to the brake shoe that comes into contact.

Vorzugsweise werden die Reinigungsvorrichtungen so angeordnet, daß ihre Träger gleichzeitig mit der Bremsbacke bewegt werden.Preferably, the cleaning devices are arranged so that their carriers are simultaneous be moved with the brake shoe.

Es sei bemerkt, daß es bereits bei elektromagnetischen Schienenbremsen bekannt ist, die Beseitigung von Eis oder Schnee von den Schienen durch der Schienenbremse vorgeschaltete Reinigungsvorrichtungen zu bewirken. It should be noted that it is already known in the case of electromagnetic rail brakes, the removal of ice or snow from the rails by the rail brake upstream To effect cleaning devices.

In der Zeichnung ist die Erfindung beispielsweise veranschaulicht, und zwar zeigt α einen aus nichtmetallischem, verschleißfestem Stoff von hohem Reibwert bestehenden Bremsklotz, b das Rad eines Schienenwagens. Ci1 ist ein Bremsklotzhalter, an dem zwei Schleifklötze c vorgesehen sind, die mit Hilfe +5 von Schrauben C1 auswechselbar an je einem topfartigen Teil d angeordnet sind, der in einem diesen topfartigen Teil umgebenden Teil/ gelagert ist. Dieser Teil/ ist an dem Bremsklotzhalter ax mit Hilfe einer Schraube g befestigt, die den Umfang des Teiles / mit Hilfe von Klammern h einstellbar festzuhalten vermag, /ist eine in den Teil d eingeschraubte Schraube, die durch Anziehen ihrer Muttern^ einer innerhalb der Teile d, f liegenden Feder k eine Vorspannung zu erteilen vermag. Die Schleifklötze C bestehen aus einer Schleifmasse, beispielsweise Korund, die zwecks Erreichung einer hohen Verschleißdauer in ihrer Körnung und Bindung der Beschaffenheit bzw. der Härte der Bandage angepaßt sein kann. In der in der Zeichnung veranschaulichten Losstellung der Bremse sind die Schleifklötze c nur um die Entfernung m vonIn the drawing, the invention is illustrated by way of example, namely α shows a brake pad made of non-metallic, wear-resistant material with a high coefficient of friction, b the wheel of a rail car. Ci 1 is a brake block holder on which two grinding blocks c are provided, which are arranged with the help of +5 screws C 1 exchangeably on a cup-like part d , which is mounted in a part / surrounding this cup-like part. This part / is fastened to the brake block holder a x with the aid of a screw g , which is able to adjustably hold the circumference of the part / with the aid of brackets h , / is a screw screwed into part d which, by tightening its nuts ^, is a screw within the Parts d, f lying spring k is able to give a preload. The grinding blocks C consist of an abrasive compound, for example corundum, which, in order to achieve a long wear life, can be adapted in its grain size and bond to the nature or hardness of the bandage. In the position of the brake illustrated in the drawing, the sanding blocks c are only by the distance m from

dem Umfang des Rades b entfernt, während der Bremsklotz α von diesem Umfang einen größeren Abstand« aufweist. Beim Anziehen der Bremse kommen also die Schleifklötze c zuerst mit dem Umfang des Rades δ in Berührung. Sie sind geeignet, die Oberfläche des Rades von Verunreinigungen zu befreien, wodurch die Bremsklötze« außerordentlich geschont werden. Die Schleifklotz^ habenremoved from the circumference of the wheel b , while the brake pad α has a greater distance from this circumference. When the brake is applied, the sanding blocks c first come into contact with the circumference of the wheel δ. They are suitable for removing dirt from the surface of the wheel, which is extremely gentle on the brake pads. The sanding block ^ have

ίο ferner die Aufgabe, kleine Schleifflächen, die beim Anfahren und Bremsen entstehen, wieder auszuschleifen und so die Bandage dauernd gleichzuhalten.ίο also the task of making small sanding surfaces that when starting and braking arise, grind out again and thus the drum permanently to keep the same.

Durch, den federndien Anpreßdruck wirkt der Andruck der Schleifklötze c, trotzdem diese früher mit dem Radumfang in Berührung kommen als der Bremsklotz a, nicht so stark wie der Andruck des starr mit dem Bremsklotzhalter ax verbundenen Brems-Due to the resilient contact pressure, the pressure of the sanding blocks c, although they come into contact with the wheel circumference earlier than the brake block a, is not as strong as the pressure of the brake , which is rigidly connected to the brake block holder a x.
