A steplessly variable transmission is described in which a driving element and a driven element are adjustable eccentrically to one another and are coupled via pivotal levers which are journalled on one element and can be brought into force transmitting clamping engagement with the other element via coupling shoes. In the context of this series connection the two change speed units are inversely combined with an eccentric positioning device being provided which either jointly actuates the members with the ring tracks associated with the coupling elements or the members with the coupling elements. The force transmitting zones of engagement of the two units are angularly displaced relative to one another and the eccentricities of the two units and also the lever arms associated with the coupling elements can be so selected that ideal transmission ratios result which are largely free of fluctuations.
Steplessly variable transmission comprising a drivable element and a driving element which are rotatably and coaxially journalled and are connected together via at least two change speed units arranged sequentially, the change speed units having input and output members, the driving element being connected with the input member of the first sequentially arranged change speed unit and the drivable element being connected with the output member of the last sequentially arranged change speed unit, the change speed unit having the output member journalled axially parallel to the respective input member and being displaceable relative thereto, the input and output members of the change speed unit being coupled together by a plurality of pivotal levers having first and second ends, the first end pivotally journalled, and the second end having a coupling element which enters into force transmitting clamping engagement during operation with regions of a ring track, wherein the improvement comprises
