Description

  

  Getriebe mit stufenlos veränderbarem     Übersetzungsverhältnis       Das Hauptpatent bezieht sich auf ein Getriebe  mit     stufenlos    veränderbarem     übersetzungsverhältnis,     das sich gemäss dem Patentanspruch :desselben da  durch auszeichnet,     :

  dass    mindestens zwei auf der An  triebswelle     angeordnete        Schwingungserzeuger,        die    in  bezug auf ihre     Schwingungsamplitude    einstellbar  sind, und Mittel zum Übertragen der Schwingbewe  gung der     Schwingungserzeuger    auf koaxial zur Ab  triebswelle angeordnete Einwegkupplungen vorgese  hen sind, und dass die Bewegungen der Einwegkupp  lungen über ein     Differentialgetriebe    auf die Abtriebs  welle übertragen werden.

   Bei dem im Hauptpatent  beschriebenen Ausführungsbeispiel dienen als Mittel  zum     übertragen    der Schwingbewegung der als  Schwingungserzeuger dienenden Exzenter ;auf die  Einwegkupplungen     flexible    Bänder aus Stahl,     Leder     und dergleichen, welche die Aussenringe :der Einweg  kupplungen teilweise umschlingen.  



  Das Zusatzpatent bezieht sich nun auf eine wei  tere Ausführungsform des Getriebes nach dem     Pa-          tentansprudh    des Hauptpatentes, die dadurch ge  kennzeichnet ist, dass die Mittel zum übertragen der  Schwingbewegung :der Schwingungserzeuger :auf die  Einwegkupplungen starre Pleuelstangen sind, deren       Pleuelfüsse    drehbar auf :den     als        Schwingungserzeuger     dienenden     Exzenterscheiben    gelagert     sind,    während  deren     Pleuelköpfe    schwenkbar an den Aussenringen  der Einwegkupplungen     angelenkt    sind.  



  In der Zeichnung ist ein Ausführungsbeispiel des  Erfindungsgegenstandes dargestellt. Sie zeigt die Sei  tenansicht des .im Hauptpatent beschriebenen Ge  triebes, bei welchem anstelle von Bändern Pleuel-         stangen    als Mittel zur Übertragung der Schwingbe  wegung vorgesehen sind. In der Zeichnung sind  gleiche bzw. entsprechende Teile mit gleichen     über-          weisungszeichen    wie im Hauptpatent     bezeichnet.     



  Die Antriebswelle 2 mit den exzentrischen     Nok-          ken    4, auf deren zylindrischen Aussenflächen je     eine          Exzenterscheibe    5 gelagert ist, entspricht genau der  Ausführungsform nach dem Hauptpatent. Auf jeder       Exzenterscheibe    5 ist auf nicht dargestellten Walzen  oder Nadeln ein Ring 6 gelagert, der als Fuss einer  Pleuelstange 9a ausgebildet ist. Der Kopf der Pleuel  stange 9a ist am Flansch 16a :des Ringes 16 schwenk  bar befestigt, der den Aussenring der Einwegkupp  lung bildet, die wie beim Ausführungsbeispiel nach  dem Hauptpatent die Rollen 15 und die Hülse 11 um  fasst, welche drehbar auf der     Abtriebswelle    3 sitzt.  



  Die Wirkungsweise des Getriebes entspricht der  jenigen nach dem Hauptpatent.



  Transmission with continuously variable transmission ratio The main patent relates to a transmission with continuously variable transmission ratio, which is characterized by:

  that at least two vibration generators arranged on the drive shaft, which are adjustable with regard to their vibration amplitude, and means for transmitting the Schwingbewe movement of the vibration generators to one-way clutches arranged coaxially to the drive shaft are provided, and that the movements of the one-way clutches are provided via a differential gear the output shaft are transmitted.

   In the embodiment described in the main patent, the means for transmitting the oscillating movement are the eccentrics, which act as a vibration generator; flexible strips of steel, leather and the like on the one-way clutches, which partially wrap around the outer rings: the one-way clutches.



  The additional patent now relates to a further embodiment of the transmission according to the patent application of the main patent, which is characterized in that the means for transmitting the oscillating movement: the vibration generator: the one-way clutches are rigid connecting rods, the connecting rod feet of which are rotatable on: the eccentric disks serving as vibration generators are mounted, while their connecting rod heads are pivotably articulated to the outer rings of the one-way clutches.



  An exemplary embodiment of the subject matter of the invention is shown in the drawing. It shows the side view of the transmission described in the main patent, in which connecting rods are provided as a means for transmitting the oscillating motion instead of bands. In the drawing, the same or corresponding parts are denoted by the same transfer symbols as in the main patent.



  The drive shaft 2 with the eccentric cams 4, on the cylindrical outer surfaces of which an eccentric disk 5 is mounted, corresponds exactly to the embodiment according to the main patent. On each eccentric disk 5, a ring 6 is mounted on rollers or needles (not shown) which is designed as the foot of a connecting rod 9a. The head of the connecting rod 9a is attached to the flange 16a: of the ring 16 swiveling bar, which forms the outer ring of the one-way coupling, which, as in the embodiment according to the main patent, includes the rollers 15 and the sleeve 11, which is rotatably seated on the output shaft 3 .



  The mode of operation of the gearbox corresponds to that of the main patent.
