The invention is based on the object of avoiding these disadvantages .
Die erfindungsgemäße Bremse ist gekennzeichnet durch mindestens ein durch die Druckluft aufblähbares Druckkissen und durch mindestens ein undrehbares, durch das Druckkissen uiii,iit-Lelbar an das sieh drehende Bremsteil anpreßbares, Brerriselement. Durch die V#"rw.eridung eines elastischen Druckkissens ergeben sich sowohl belTrommel- als auch bei Scheibenbremsen die verschiedensten konstruktiven Lösungen,-welche bei.Verwendung eines'herkömmlichen Bremszylinders' undenkbar wären. So läßt sich durch eine entsp:i7eclie-lide Vergrösserung der Druckfläche des Druckkissens das Bremsmoment entsprechend ver--röserii so daß auf ein Kraftübersetzungselement verzichtet werden kann. Durch die &norch iung des Druckkissens unmittelbar an dem undrehbaren Teil der Bremse kann man auf besondere Kraftübertragung?-elemente verzichten.-Nach-einer weiteren Äusbildung der Erfindung ist das Druckkissen bei Verwendung für eine Scheibenbremse, 'bei welcher die Aufblähung in axialer Richtung-ausgenützt wird, als ebener Vollringkörper ausgebildet, in einen undrehbar auf den iiclisl-,örper angeordneten scheibenförmi:'en Druck-9 kissenhalter geführt und --in diesem ii-i-4tels der Drucklufturnatur gehaltert und das sich drehende Bremsteil unmittelbe##r an der Innenseite der Radnabe befestigt. Diese Gestaltung ergibt nicht nur einen einfachen Aufbau der Bremse, die nur wenige Teile umfaßt, sondern ermöglicht-auch ein,Iiiaximum an Bremsdrudkfläche und damit an Bremskraft- trotz des verli##iltiiisri.#'i'Oig niedrigen durch die vorhandene Druckluft bedin,gteii spezifischen Flächendrückes..Der niedrige Bremsdruck hat andererseits eine längere Lebensdauer-des Bremsbelages zur Folge.The brake according to the invention is characterized by at least one pressure pad which can be inflated by the compressed air and at least one non-rotatable brake element which can be pressed against the rotating brake part by the pressure pad. The use of an elastic pressure cushion provides a wide variety of design solutions for both drum and disc brakes, which would be inconceivable if a 'conventional brake cylinder' were used Pressure surface of the pressure pad the braking torque correspondingly ver - röserii so that a force transmission element can be dispensed with. By adjusting the pressure pad directly on the non-rotating part of the brake, special force transmission elements can be dispensed with If the pressure pad is used for a disc brake, in which the inflation is exploited in the axial direction, it is designed as a flat full-ring body, guided into and in a disc-shaped pressure pad holder arranged non-rotatably on the iiclisl-, body ii-i-4tels of the compressed air system held and the rotating brake part immediately ## r on the Attached to the inside of the wheel hub. This design not only results in a simple structure of the brake, which comprises only a few parts, but also enables an optimum of brake pressure area and thus of braking force despite the fact that the compressed air is very low. gteii specific surface pressure. On the other hand, the low brake pressure results in a longer service life of the brake lining.
