Description

Freilaufnabe mit Rücktrittbremse und Lamellerlkupplung Es sind bereits Freilaufnaben mit Rücktrittbremse und Lamellenkupplung für Fahrräder bekannt, bei denen die rotierenden Lamellen mit Nasen in Nuten der Nabenhülse gehalten werden. Infolge von Werkstoff-oder Härtefehlern brechen bei starker Beanspruchung die Nasen der Lamellen leicht ab. Beim Erfindungsgegenstand wird dieser Übelstand dadurch vermieden, daß zum Mitnehmen der rotierenden Lamellen die innere Bohrung der Nabenhülse oval ausgebildet ist, also Nasen an den Lamellen nicht mehr erforderlich sind.Freewheel hub with coaster brake and multi-disc clutch There are already Freewheel hubs with coaster brake and multi-plate clutch for bicycles known at which the rotating lamellas are held in grooves in the hub shell with lugs. As a result of material or hardness defects, the noses break under heavy use the slats off slightly. With the subject matter of the invention, this is a disadvantage avoided that the inner bore of the hub shell to take along the rotating lamellae is oval, so lugs on the lamellae are no longer required.

Die beiliegende Zeichnung zeigt einen Längs- und einen Querschnitt durch die Freilaufnabe mit Rücktrittbremse.The accompanying drawing shows a longitudinal and a cross section thanks to the freewheel hub with coaster brake.

Der, Antreiber a besitzt einerseits die Gewinde für Kettenkranz und Gegenmutter, anderseits ein zweifaches Schneckengewinde, in welches die beiderseits gezahnte Antreibermutter b eingreift. Beim Anfahren wird der Antreiber a durch Kettenrad und Kette nach rechts gedreht, wodurch sich die Stirnzähne der Antreibermutter b, welche durch die Feder d gegen Verdrehung geschützt wird, mit denen des Mitnehmerringes c kuppeln, der mit der Nabenhülse g fest verbunden ist. Bei Unterbrechung der Tretbewegung wird der Antreiber a stillgesetzt, da sich infolge des drehenden Rades die Antreibermutter b vom Mitnehmerring c löst, wodurch ein einwandfreier Freilauf entsteht. Um die Bremswirkung zu erzielen, tritt man in bekannter Weise zurück, wodurch sich die Stirnzähne der Antreibermutter b mit denen des Bremsringes e kuppeln. Bei weiterem Zurücktreten wird durch die Zusammenpressung der rotierenden f gegen die feststehenden h Bremslamellen die Bremswirkung erzielt. Der Bremsdruck wird durch den Bremskonus und Bremshebel aufgefangen. Die mit der Nabe g rotierenden Lamellen f sind in ihrem Querschnitt dem ovalen Querschnitt der Nabenhülse g angepaßt, so rlaß sie einwandfrei auch bei stärkster Beanspruchung festgehalten werden, ohne Beschädigung zu erleiden.The driver a has on the one hand the thread for the chain ring and lock nut, on the other hand a double worm thread in which the driver nut b, which is toothed on both sides, engages. When starting, the driver a is rotated to the right by the sprocket and chain, whereby the front teeth of the driver nut b, which is protected against rotation by the spring d, couple with those of the driver ring c, which is firmly connected to the hub sleeve g. When the pedaling movement is interrupted, the driver a is stopped because the driver nut b is released from the driver ring c as a result of the rotating wheel, which results in a perfect freewheel. In order to achieve the braking effect, one steps back in a known manner, whereby the front teeth of the driver nut b couple with those of the brake ring e. If you step back further, the braking effect is achieved by compressing the rotating f against the stationary h brake discs. The brake pressure is absorbed by the brake cone and brake lever. The lamellas f rotating with the hub g are adapted in their cross-section to the oval cross-section of the hub sleeve g, so that they can be properly held even under the greatest stress without suffering damage.
