Beschreibung: Rollenkette mit Reibscheiben für stufenlose Getriebe.Description: Roller chain with friction discs for continuously variable transmissions.
Es sind stufenlose Automatikgetriebe bekannt, die mit 2 Kegelscheibenpaaren arbeiten und als Übertragungsorgan Keilriemen, Gliederbänder oder dergl. benutzen. Die dabei iTriertragbare Energie bleibt beschränkt.Continuously variable automatic transmissions are known that work with 2 pairs of conical pulleys and use V-belts, link belts or similar as transmission elements. The energy that can be transferred in this way remains limited.
Der Vorschlag sieht vor, als Übertragungsorgan derzeit bekannte Rollenketten als Basis zu verwenden. Dabei sind jedoch die einzelnen Wellen der Rollen über die Verbindungsglieder der Rollen hinaus zu verlängern. Um je eine Rolle herum wird eine kegelförmige Doppelreibscheibe (A 1 und A 2) angeordnet, die beiderseits ein Lager zur Aufnahme dieser verlängerten Wellenenden aufweist. Die Doppelreibscheibe besteht aus zwei identischen Teilen, die miteinander verschraubt oder sonst fest verbunden sind. Innerhalb der Doppelreibscheibe verbleibt somit ein Raum C zur Aufnahme der Rollenkette und deren Führung. Zusätzlich kann in der Reibscheibe A auf jeder Seite ein von aussen zu verschliessender Hohlraum D 1 und D 2 zur Aufnahme einer Dauer-Fettschmierung B 1 und B 2 angeordnet wurden. Die Reibscheiben A sind oberhalb der Wellen dicht bei dicht angeordnet, so dass sie bei gerader Straffung einander stützen. (Skizze unten).Unterhalb der Wellen weisen sie eine kreisrunde Form auf, so dass sie auch bei Umrundimg der Kegelscheiben den gegenseitigen Kontakt nicht· verlieren.The proposal is to use currently known roller chains as a basis for the transmission mechanism. However, the individual shafts of the rollers must be extended beyond the connecting links of the rollers. A conical double friction disk (A 1 and A 2) is arranged around each roller, which has a bearing on both sides to accommodate these extended shaft ends. The double friction disk consists of two identical parts that are screwed together or otherwise firmly connected. A space C thus remains within the double friction disk to accommodate the roller chain and its guide. In addition, a cavity D 1 and D 2 that can be closed from the outside can be arranged in the friction disk A on each side to accommodate a permanent grease lubrication B 1 and B 2. The friction disks A are arranged close together above the shafts so that they support each other when tightened straight. (Sketch below). Below the shafts they have a circular shape so that they do not lose contact with each other even when they rotate around the conical disks.
