Description
Die Erfindung betrifft eine Rollenbremse zum Verhindern des Festbremsens von Fahrzeugrädern, bei der zwischen Platten drehbar gelagerte konische Rollen durch axiale Ver-Schiebung in einen mit der Bremstrommel fest verbundenen und mit derselben umlaufenden Ring aus elastischem Werkstoff (Gummi) und in einen zweiten mit einer feststehenden Trommel verbundenen Ring gleicher Art eingedrückt werden, um so den von der Geschwindigkeit abhängigen Rollwiderstand zur Bremsung nutzbar zu machen.The invention relates to a roller brake for preventing vehicle wheels from locking, with the conical rollers rotatably mounted between plates by axial displacement into a ring made of elastic material (rubber) and permanently connected to the brake drum and rotating with the same pressed into a second ring of the same type connected to a stationary drum in order to make use of the rolling resistance, which is dependent on the speed, for braking.
Bremsanlagen arbeiten zur Zeit fast ausnahmslos mit Bremsbacken oder -scheiben, welche zur Erhöhung des Reibungswertes mit unterschiedlichem Belag versehen sind.Brake systems currently work almost without exception with brake shoes or discs, which are provided with different linings to increase the coefficient of friction.
Die Nachteile solcher auf dem Reibungsprinzip beruhenden Anlagen sind bekannt. Sie bestehen in der Hauptsache darin, daß das Material der Bremsbacken und -scheiben bzw. -trommeln einem hohen Verschleiß unterliegt und einer öfteren Nachstellung und Erneuerung bedarf.The disadvantages of such systems based on the principle of friction are known. The main thing is that the material of the brake shoes and discs or -drums are subject to high wear and tear and are subject to frequent readjustment and renewal requirement.
Die Betriebssicherheit derartiger Anlagen ist in hohem Maße von der Fahr- bzw. Bremstechnik des Fa_hrers abhängig, besonders wenn dieselben blockierungs-, stoß- und geräuschlos arbeiten sollen.The operational safety of such systems depends to a large extent on the driving and braking technology depending on the driver, especially when the same without blocking, jolting and noiseless should work.
Eine Bremsanlage, die die erwähnten Nachteile und insbesondere das Festbremsen der Fahrzeugräder vermeidet, ist nachstehend beschrieben. Es zeigenA braking system that has the disadvantages mentioned and in particular the locking of the Avoiding vehicle wheels is described below. Show it

In den Abbildungen ist die äußere, in Pfeilrichtung sich drehende Bremstrommel 1, welche mit einer Gummiauflage 2 versehen ist, auf der Achswelle 16 befestigt.In the figures, the outer brake drum 1 rotating in the direction of the arrow, which is provided with a rubber pad 2, attached to the axle shaft 16.
Die innere Bremstrommel 9 mit einer Gummiauflage 8 ist mit dem Achsrohr 10 fest verbunden.The inner brake drum 9 with a rubber pad 8 is fixed to the axle tube 10 tied together.
Die auf den Wellen 4 zweckmäßig kugelgelagerten konischen Rollen 3 sind auf der Druckplatte S, welche auf dem Achsrohr 10 dreh- und verschiebbar gelagert ist, angebracht. The on the shafts 4 expediently ball-bearing conical rollers 3 are on the Pressure plate S, which is mounted rotatably and displaceably on the axle tube 10, is attached.
In der Hilfsbremsscheibe 7, welche mit Bremsbelag versehen ist, sind die Achswellen 4 der Rollen 3 befestigt. In the auxiliary brake disc 7, which with Brake lining is provided, the axle shafts 4 of the rollers 3 are attached.
Der Bremsvorgang geht bei dieser Anlage S so vor sich, daß bei Betätigung der Druckplatte 5 durch den Bremshebel 13, welcher in der mit dem Achsrohr 10 feststehenden Abdeckscheibe 15 gelagert ist, über die mit schrägen Gleitflächen versehene, drehbar gelagerte Druckscheibe 12 und die mit entsprechenden Gegenflächen versehene, axial verschiebbare Scheibe 11 die Rollen 3 in die Gummiauflagen der Trommeln 1 und 9 gedruckt werden. Durch den Rollenwiderstand tritt bei großerThe braking process goes on in this system S so that when the pressure plate is actuated 5 by the brake lever 13, which is in the fixed with the axle tube 10 cover disc 15 is mounted, via the rotatably mounted one provided with inclined sliding surfaces Thrust washer 12 and the axially displaceable one provided with corresponding mating surfaces Washer 11 the rollers 3 are pressed into the rubber pads of the drums 1 and 9. Due to the roller resistance occurs at large

Die Rollen 3 können beispielsweise auch in zylindrischer Form ausgeführt sein und radial durch geeignete Übertragungsglieder an ein oder mehrere mit der Bremsanlage in Verbindung stehende Gummiauflagen herangeführt werden. The roles 3 can, for example, also in be designed cylindrical shape and radially through suitable transmission members to a or several rubber pads connected to the brake system are brought up.
