Description

Bremse für Kraftfahrzeuge. Die Erfindung betrifft eine Scheibenbremse, bei der zwei seitlich wirkende, auseinanderdrückbare, im übrigen feststehende Bremsscheiben zwischen je zwei mit dem Rad umlaufenden Reibflächen der Trommel angeordnet sind, und daß diese Scheiben einen doppelkeilförmigen Zwischenraum bilden, in dem ein biegsamer, federnder Drahtring oder ein ähnliches Glied zum Spreizen der erstgenannten Ringe benutzt wird, um die Bremsringe mit jedem Flächenelement wirksam zu machen.Brakes for automobiles. The invention relates to a disc brake, with two laterally acting, pushable apart, otherwise stationary brake discs are arranged between two friction surfaces of the drum rotating with the wheel, and that these disks form a double wedge-shaped space in which a flexible, resilient wire ring or a similar member for spreading the former Rings is used to make the brake rings effective with each panel.

Die Zeichnung veranschaulicht durch Abb. i links einen Längsschnitt nach der Linie a der Abb. 2, rechts eine Vorderansicht, durch Abb. 2 einen Querschnitt nach der Linie b der Abb. i.The drawing illustrates a longitudinal section through Fig. I on the left according to the line a of Fig. 2, right a front view, through Fig. 2 a cross section according to the line b of Fig. i.

Auf der Radnabe i ist in bekannter Weise die Bremstrommel 2 befestigt, in deren Innern einander gegenüber zwei Reibflächen 3 aus einem Werkstoff mit hohem Reibungskoeffizienten angeordnet sind. Mit der ruhenden Radachse 4 und dem Fahrzeugrahmen verbunden ist eine Scheibe 5 mit Flansch 6, die in das Gehäuseinnere 2 paßt und die beiden Bremsscheiben 7 trägt. Zwei Ansätze 8 in der Form von Kreisringausschnitten am Flansch 6 sorgen dabei für die Sicherung der Bremsscheiben 7 gegen Drehung. Diese sind so gestaltet, daß sie nach außen die beiden Reibflächen 3 bedecken und nach innen einen Hohlraum 9 bilden, der doppelkeilförmigen Querschnitt hat. In diesem Hohlraum 9 liegt ein ringförmig gebogener elastischer Draht io oder ein demselben gleichwertiges Glied, dessen eines Ende i i an den Ansätzen 8 befestigt und dessen anderes Ende mit einem an der Scheibe 5 gelagerten Winkelhebel 12 gelenkig verbunden ist. Beim Drehen desselben mittels des Bremsgestänges bzw, -kabels wird der Durchmesser des Drahtringes io verringert, so daß er die beiden Bremsscheiben durch Einwirkung auf ihre Keilflächen g auseinander- und an die Reibflächen 3 der Bremstrommel drückt, wodurch -das Bremsen des Fahrzeuges erfolgt. Um die beim Anziehen der Bremsen zwischen dem Drahtring io und den Bremsscheiben 7 auftretende Reibung, die zu .einer erheblichen Gegenkraft anschwellen kann, zu vermindern, können Kugeln. oder Rollen in geeigneter Weise zwischen beide Organe eingeschaltet werden.On the wheel hub i, the brake drum 2 is attached in a known manner, in the interior of each other opposite two friction surfaces 3 made of a material with high Friction coefficients are arranged. With the stationary wheel axle 4 and the vehicle frame connected is a disc 5 with flange 6, which fits into the housing interior 2 and the two brake disks 7 carries. Two approaches 8 in the form of circular ring sections on the flange 6 ensure that the brake disks 7 are secured against rotation. These are designed so that they cover the two friction surfaces 3 to the outside and after form inside a cavity 9, which has a double wedge-shaped cross-section. In this Cavity 9 is an annularly bent elastic wire io or the same equivalent member, one end of which i i attached to the lugs 8 and of which the other end is articulated to an angle lever 12 mounted on the disk 5 is. When turning it by means of the brake rod or cable, the diameter of the wire ring io reduced, so that he acts on the two brake disks pushes apart on their wedge surfaces g and on the friction surfaces 3 of the brake drum, whereby the vehicle is braked. To keep the brakes on between the wire ring io and the brake disks 7 occurring friction, which leads to .einer considerable Counterforce can swell, diminish, balls can. or roles in appropriate Way to be switched between both organs.
