ABSTRACT:
An infinitely variable (I.V.) transmission unit having a single input and at least two independently rotatable outputs driven by rolling friction surfaces with a variable radius ratio and by unit contained gearing. The separate output shafts are coupled with distinct gear reduction functions to a single I.V. functioning or working unit to enable different output/input speed ratio ranges to be achieved by each unit output.
The unit is combined with a simple external gear set and clutching to provide diverse system operation in which the range of I.V. operation is enlarged. Also, synchronous operation of the system is achieved with no external epicyclic gear operation.
