Description

  

      Fahrradantrieb.            Vorliegende    Erfindung betrifft einen       Fahrradantrieb.     



       Die    beiliegende Zeichnung veranschau  licht ein     Beispiel        de        Erfindungsgegen-          standes,    und zwar zeigt:       Fig.    1 eine     Seitenansicht    des Antriebes,  ein     Gehäusedecli:el    weggelassen,       Fig.    2 einen     Quemchnitt    desselben.  



  In der Zeichnung ist 1 die Tretkurbel,  die auf der     Tretkurbelachse    2 fest sitzt. Auf  der     Tretkurbelachse    sitzt     ferner    lose das       Kettenrad    3, welches     vermittelst    einer Kette  die Bewegung auf das Hinterrad überträgt.

    Mit dem Kettenrad 3     ist    ein Zahnrad 4 fest       verbunden,    welches. drehbar auf der     Tret-          kurbelachse,    angeordnet     ist.    Das Zahnrad 4  greift in ein Zahnrad 5, welches an der  Tretkurbel 1 drehbar     gelagert    ist.     Das    Zahn  rad 5 greift in ein     feststehendes    Hohlrad  6 ein.  



  Beim Drehen der Tretkurbel 1 dreht sich  das an ihr drehbar gelagerte Zahnrad 5 einer-         seits    planetarisch um, anderseits dreht es sich  in     entgegengesetzer    Richtung wie die Kurbel  um Seineeigene Achse. Dadurch werden das  Zahnrad 4 und das Kettenrad 3 mit erhöhter  Geschwindigkeit in gleicher Richtung wie  die Kurbel gedreht. Die Räder 4, 5 und 6  sind durch die Gehäuseteile 7 und 7' ge  schützt. Der Deckel 7' dreht sich mit der  Tretkurbel. 8 ist eine Konsole, die zur Be  festigung des Hohlrades 6 dient.



      Bicycle drive. The present invention relates to a bicycle drive.



       The accompanying drawing illustrates an example of the subject matter of the invention, specifically showing: FIG. 1 a side view of the drive, a housing cover omitted, FIG. 2 a cross section of the same.



  In the drawing, 1 is the pedal crank that is firmly seated on the pedal crank axle 2. The sprocket 3, which transmits the movement to the rear wheel by means of a chain, also sits loosely on the pedal crank axle.

    With the chain wheel 3, a gear 4 is firmly connected, which. is rotatably arranged on the pedal crank axle. The gear 4 engages in a gear 5 which is rotatably mounted on the pedal crank 1. The toothed wheel 5 engages in a fixed ring gear 6.



  When the crank 1 is rotated, the gear 5 rotatably mounted on it rotates on the one hand planetary, on the other hand it rotates in the opposite direction to the crank around its own axis. As a result, the gear 4 and the chain wheel 3 are rotated at an increased speed in the same direction as the crank. The wheels 4, 5 and 6 are protected by the housing parts 7 and 7 'ge. The cover 7 'rotates with the pedal crank. 8 is a console that is used to fasten the ring gear 6 Be.

Claims (1)

PATENTANSPRUCH: Fahrradantrieb, dadurch gekennzeichnet, dass an der Tretkurbel ein Zahnrad drehbar gelagert ist, welches Rad sowohl in ein fest stehendes Hohlrad als auch in ein weiteres Zahnrad eingreift, welch letzteres drehbar auf der Tretkurbelachse sitzt und mit dem treibenden Kettenrad fest verbunden ist. PATENT CLAIM: Bicycle drive, characterized in that a gear wheel is rotatably mounted on the crank, which wheel engages both in a stationary ring gear and in another gear, the latter being rotatably seated on the crank axle and firmly connected to the driving sprocket.
