    • Die Erfindung betrifft eine Mehrgangnabe mit Rücktrittbremse für Fahrräder mit einer Nabenhülse (2), einem Antreiber (5), einem Planetengetriebe (3) und einer Rücktrittbremseinrichtung (4). Es wird vorgeschlagen, die Schaltung der Getriebeteile so zu gestalten, daß für alle möglichen schaltbaren Gänge beim Antrieb des Antreibers (5) in einer Bremsdrehrichtung (B) immer eine Bremsverstärkung der Rücktrittbremseinrichtung (4) über das Planetengetriebe (3) erzielt wird. Im Normalgang und im Berggang verläuft der Antrieb vom Antreiber (5) über eine Längsverzahnung (13) eines Kupplungsrades (9) auf die eine Kupplungsverzahnung (14) auf ein Hohlrad (6), was beim Antrieb in Bremsdrehrichtung (B) eine Bremskraftverstärkung mit der Betätigung der Rücktrittbremseinrichtung (4) bewirkt. Im Schnellgang wird die vorteilhafte Bremskraftverstärkung durch das Planetengetriebe beim Antrieb in Bremsdrehrichtung (B) dadurch erzielt, daß die Kupplungsscheibe (10) vom Planetenradträger (7) abgewiesen und mit dem Hohlrad (6) gekoppelt wird, so daß auch im Schnellgang eine Bremskraftverstärkung erzielt wird.

    • A method of manufacturing a hub member (50) for use in a coaster brake (52). A supply of tubular stock material (8) is transported to a work station and the interior thereof machined to establish first and second diameters (16) and (17), respectively, separated by a shoulder (15). A cylindrical member (10) is cut from the stock (8) and placed in a fixture (36). A disc or ring member (30) has a peripheral surface with a serrated section (32) separated from a shoulder (33) by a groove (35). The disc or ring member (30) is placed on a second fixture (38) and brought into alignment with diameter (16) of the cylindrical member (10). A ring of brazing material (37) is placed in groove (35). A force is applied to move disc member (30) into the diameter (16) of the cylindrical member (10). The serrated surface (32) on disc or ring member (30 ) engages diameter (17) to distort material therein and establish a mechanical joint (44). The force continues to move the second fixture (38) toward the first fixture (36) until face (42) on shoulder (33) of the disc or ring member (30) engages shoulder (15) on cylindrical member (10). Thereafter, the cylindrical member (10) with disc or ring member (30) insert is transported to an oven and heated sufficiently to flow the brazing material (37) into joint (44) to establish a brazed joint for the hub member (50).
