Die Hauptpatentanmeldung betrifft eine Reibungskupplung oder -bremse, deren Reibkörper schmaler Umfangserstreckung sich am Reibkranz in statisch bestimmter Auflage abstützen, wobei die Reibungskupplung oder -bremse so ausgebildet ist, daß sie unabhängig von dem Reibungskoeffizienten der Reibkörper durch vektorielle Kräfteverlagerung wirkt, indem sie sich selbsttätig einstellt.The main patent application relates to a friction clutch or brake, the friction body of which is narrower Circumferential extension are supported on the friction ring in a statically determined support, with the friction clutch or brake is designed so that it is independent of the coefficient of friction of the friction body works through vectorial forces shifting by adjusting itself.

Das vorliegende Zusatzpatent hat eine Erhöhung der Wirksamkeit gegenüber der mit der A b b. 3 der Hauptpatentanmeldung beschriebenen Anordnung zum Gegenstand, die an Hand der hier zugehörigen Abbildung als Beispiel beschrieben sei. Es handelt sich dabei um dieselbe Darstellungsweise, deren sich die Hauptpatentanmeldung in seiner A b b. 3 bedient, deren Einzelheiten auch hier in vollem Umfange, wie in der Hauptpatentanmeldung beschrieben, als Grundlage dienen.The present additional patent has an increase in effectiveness compared to the A b b. 3 of the Main patent application described arrangement on the subject, which is based on the associated here Figure is described as an example. This is the same way of representation that the main patent application in its A b b. 3, the details of which are also used here in full, such as described in the main patent application, serve as a basis.

Während bei der Hauptpatentanmeldung für die statisch bestimmte Auflage der zur Bewirkung der vektoriellen Kräfteverlagerung vorgesehene Reibbacken 6 je einen Reibkörper links und rechts der Wirkungslinie der Resultierenden Pres an den Punkten A1 und A2 zur Abstützung bringt, soll auch bei Anwendung von mehr als zwei Reibkörpern die statisch bestimmte Abstützung sichergestellt werden. Hierzu kann insbesondere im Bereich der höchsten Beanspruchung der im Kranzpunkt A2 abgestützte Reibkörper des Backens 6 auch in zwei Reibkörper 2" und 2'" mit den den Tragpunkten A2' und A3' unter Beibehaltung der statischen Bestimmtheit dei Abstützung aufgeteilt werden. Zu diesem Zweck ist eine Art Waagbalken 14 vorgesehen, der zwischen den an ihm zur Aufnahme der beiden Reibkörper 2" und 2'" gebildeten halbkreisförmigen Rinnen auf der Unterseite eine Mulde mit scharfer Einkerbung entstehen läßt, womit ein Schneidlager 16 geschaffen ist, in welchem sich der Backen 6 in Ausübung seines Anpreßdruckes in der reibungswirksamen Zone nunmehr an den zwei Reibkörpern 2" und 2"' unter demselben Winkelabstand vom Punkt A1 am Umfang des Reibkranzes 1 vom Radius r abstützt, wie dies in Abb. 3 der Hauptpatentanmeldung bei dem nur einen Reibbacken im Punkt A2 der Fall ist.While in the main patent application for the statically determined edition of the friction jaws 6 provided for effecting the vectorial shifting of forces, one friction body each to the left and right of the line of action of the resultant P res at points A 1 and A 2 should be supported, should also be used when using more than two Friction bodies the statically determined support are ensured. For this purpose, especially in the area of the highest stress, the friction body of the jaw 6 supported at the crown point A 2 can also be divided into two friction bodies 2 "and 2 '" with the support points A 2 ' and A 3 ' while maintaining the static determinacy of the support. For this purpose a kind of balance beam 14 is provided, which creates a trough with a sharp notch on the underside between the semicircular grooves formed on it for receiving the two friction bodies 2 "and 2 '" , whereby a cutting bearing 16 is created in which the jaw 6 in the exercise of its contact pressure in the friction zone is now supported on the two friction bodies 2 "and 2"' at the same angular distance from point A 1 on the circumference of the friction rim 1 from the radius r , as shown in Fig. 3 of the main patent application in which only a friction shoe at point A 2 is the case.

Wie der Kräfteplan zeigt, setzen sich die in den Kranz-Auf lagepunkten A2' und A3 der Reibkörper 2" und 2"' entstehenden Einzelkomponenten im Punkt Sn (für den der durch die Punkte A2, ΑΆ, Ο gezogene Hilfskreis C der geometrische Ort ist) zu einer Teilresultante P23 res zusammen, die ihrerseits mit der vom Reibkörper 2 im Punkt A1 kommenden Komponente P1 sich im Punkt S (für den der durch Reibungskupplung oder -bremseAs the force plan shows, the individual components arising in the wreath support points A 2 ' and A 3 of the friction bodies 2 "and 2"' settle in point S n (for which the auxiliary circle drawn through points A 2 , Α Ά , Ο C is the geometric location) to a partial result P 23 res , which in turn with the coming from the friction body 2 at point A 1 component P 1 at point S (for the friction clutch or brake

a5 stant bleibenden Summe der an den Einzelreibkörpern 2, 2", 2"' je nach dem gerade herrschenden Reibungskoeffizienten entstehenden Umfangskräfte IZ1, U2, U3 auszuweisen hätte.
Dieser Effekt der vollen Reibwertunabhängigkeit tritt aber nur dann in aller Exaktheit ein, wenn man mit der Waagbalkenschneide 16 des Backens 6 bis an den Innenumfang des Kranzes 1 mit dem Radius r herangehen kann, so daß sie mit dem Abstützpunktv42 der A b b. 3 der Hauptpatentanmeldung zusammenfällt. Da aber die Waagbalkenschneide 16 aus konstruktiven Gründen radial verkürzt ausgeführt werden muß, verschiebt sich der Schnittpunkt der Wirkungslinie von P23 res mit dem Innenkreis der Trommel 1 vom Radius r von A2 nach A2", wo er aber nicht unverrückbar bestehenbleibt, sondern hier, je nach Größe des gerade herrschenden Reibungskoeffizienten, sich immer wieder verschiebt.
a5 remaining constant sum of the individual friction bodies 2, 2 ", 2"' depending on the prevailing coefficient of friction IZ 1 , U 2 , U 3 would have to be shown.
This effect of full independence from the coefficient of friction only occurs with all accuracy if one can approach the inner circumference of the rim 1 with the radius r with the balance bar blade 16 of the jaw 6, so that it is connected to the support point v4 2 of the A b b. 3 of the main patent application coincides. However, since the beam edge 16 has to be shortened radially for structural reasons, the intersection of the line of action of P 23 res with the inner circle of the drum 1 shifts from radius r from A 2 to A 2 ", where it does not remain immovable, but here , depending on the size of the currently prevailing coefficient of friction, shifts again and again.

Es steht frei, Mittel vorzusehen, dem reibwertabhängigen Wandern des PunktesA2 nach A2" dadurch zu begegnen, daß die Punkte A2 und A3 des Waagbalkens 14 in ungleichem Abstand von der Waagschneide 16 des Backens 6 vorgesehen werden. Auch kann man für irgendwelche Kompensationszwecke den Backendrehpunkt 7 vom Radius w aus seiner Lage auf der Verbindungslinie α zwischen dem Drehpunkt 9 des Betätigungshebels 5 und dem Rotationsmittelpunkt O mehr oder weniger verschieben.It is free to provide means to counteract the friction coefficient-dependent migration of the point A 2 to A 2 " by providing the points A 2 and A 3 of the balance beam 14 at an unequal distance from the cutting edge 16 of the jaw 6 Any compensation purposes move the jaw pivot point 7 from the radius w from its position on the connecting line α between the pivot point 9 of the operating lever 5 and the center of rotation O more or less.
