Sie haben außerdem einen sich in die andere Richtung erstreckenden Hebelarm (14) bzw. (15) mit je einem nahezu am Ende befindlichen, sich zur Mitte erstreckenden Fortsatz (16) bzw. (17), der je als eine Hälfte einer Gelenkverbindung, also kugel- oder zylinderförmig ausgebildet ist.Both levers each have a lever arm opposite the rim (7) (11) or (12), on which the brake pads (13) are attached. You also have a lever arm (14) or (15) extending in the other direction, each with one extension (16) or (17) that is almost at the end and extends towards the middle, each designed as one half of an articulated connection, i.e. spherical or cylindrical is.

Zu BESCHREIBtJNG Zwischen den Fortsätzen (16) und (17) befindet sich die hydraulische Betätigungseinrichtung. Sie besteht au; einem Zylinder (18) und einem darin verschiebbaren Kolben (19) mit einem Dichtring (23). Dem Zylinderraum (20) wird in bekannter Weise über einen Druckanschluß (21) Druckflüssigkeit zugeführt, wodurch auf die Fortsätze (16) und (17) eine Kraft ausgeübt wird, so daß die Bremsklötze (13) an die Felge (7) angedrückt werden und eine Bremswirkunq ausüben. Die Schraube (22) dient zur Entlüftung. Die Federn (24, 24') drehen die Hebel (9) und (10) nach Beendigung des Bremsvorgangs zurück.To DESCRIBE between the extensions (16) and (17) is the hydraulic actuator. It consists of; a cylinder (18) and a piston (19) displaceable therein with a sealing ring (23). The cylinder space (20) is supplied in a known manner via a pressure connection (21) pressure fluid, whereby a force is exerted on the extensions (16) and (17), so that the brake pads (13) are pressed against the rim (7) and exert a braking effect. The screw (22) is used for venting. The springs (24, 24 ') rotate the levers (9) and (10) End of the braking process.

Der Kolben (19) hat an seinem äußeren Ende eine kugel-.The piston (19) has a spherical at its outer end.

förmige Vertiefung (25), in die der ebenfalls kugelförmige Fortsatz (17) eingreift, wodurch eine gelenkige Verbindung entsteht. Die Vertiefung wird vorzugsweise so ausgeführt, daß die Kugel eingebördelt werden kann, so daß die Gelenkverbindung unlösbar ist. Der Zylinder (18) hat an seinem geschlossenen Ende ebenfalls eine kugelförmige Vertiefung (26), in die der Fortsatz (16) eingreift, der jedoch nicht eingebördelt ist , so daß die Gelenkverbindung lösbar ist. Sie wird von einem Element (27) zusammengehalten, das klammerförmig ausgebildet ist, sich am Zylinder (18) und am Hebelarm (14) abstützt und von Hand lösbar ist.shaped recess (25) into which the likewise spherical extension (17) engages, creating an articulated connection. The deepening will preferably designed so that the ball can be crimped so that the articulated connection is unsolvable. The cylinder (18) also has one at its closed end spherical recess (26) in which the extension (16) engages, but which is not is crimped so that the articulation is releasable. She is from an element (27) held together, which is designed in the shape of a bracket, is attached to the cylinder (18) and is supported on the lever arm (14) and can be released by hand.

Vorzugsweise ist das Element (27) federnd oder hat einen federnden Abschnitt (28), der in eine Raste (29) am Hebelarm (14) einrastet, so daß die Gelenkverbindung mit einer gewissen Kraft zusammengehalten wird. Besonders vorteilhaft ist es, wenn das Element (27) mit 2 Zapfen (30) in je einer entsprechenden Vertiefung am Zylinderumfang drehbar befestigt ist, wie Figur 3 zeigt.The element (27) is preferably resilient or has a resilient one Section (28) which engages in a catch (29) on the lever arm (14), so that the articulated connection is held together with a certain force. It is particularly advantageous if the element (27) with 2 pins (30) each in a corresponding recess on the cylinder circumference is rotatably attached, as Figure 3 shows.

Zu BESCHREIBUNG Zum Öffnen der Bremsbacken wird das Element (27), das zweckmäßigerweise ein Griffstück (31) hat, um die Zapfen (30) nach oben geschwenkt. Es verbleibt in den Vertiefungen des Zylinders (18) und ist somit unverlierbar. Diese Stellung ist in Figur 4 gezeigt. Anschließend werden Zylinder (18) und Kolben (19) um den Mittelpunkt des kugelförmigen Fortsatzes (17) ebenfalls nach oben gedreht.To DESCRIPTION To open the brake shoes, the element (27), which expediently has a handle (31) pivoted upwards about the pin (30). It remains in the indentations of the cylinder (18) and cannot be lost. This position is shown in FIG. Then the cylinder (18) and piston (19) also rotated upwards around the center of the spherical extension (17).

Die auf die Hebel (9) und (10) wirkenden Federn drehen diese so, daß die Backen sich öffnen. Der ganze Vorgang ist einfach, schnell und ohne Werkzeuge durchzuführen.The springs acting on the levers (9) and (10) rotate them so that the cheeks open. The whole process is easy, quick and without tools perform.

Es ist natürlich ebenso möglich, die Gelenkverbindung zwischen Zylinder (18) und Hebelarm (14) unlösbar zu gestalten und dafür diejenige zwischen Kolben (19) und Hebelarm (15) lösbar und mit einem Element ähnlich (27), das in diesem Fall am Kolbenende drehbar gehalten wäre, zu sichern. Ebenso könnten beide Gelenkverbindungen lösbar gestaltet werden, so daß Zylinder und Kolben nicht weggeschwenkt, sondern ganz entfernt werden könnten.It is of course also possible to use the articulated connection between cylinders (18) and lever arm (14) to be made inseparable and that between the piston (19) and lever arm (15) detachable and with an element similar to (27), which in this Case would be rotatably held at the piston end to secure. Likewise, both articulations could be made detachable, so that the cylinder and piston are not pivoted away, but could be removed entirely.
