Abstract
A continuously variable transmission utilizes a variable eccentric assembly arranged about a central transmission axis. A plurality of input and output vanes are operably interconnected to an orbiter and are sequentially engaged by input and output ratchets that circumscribe them. Positive driving connections are provided between the ratchets and vanes by outer toothed pawls yieldably mounted at the outer ends of the respective vanes. A secondary multiplier transmission can be arranged coaxially with the vanes, which are rotatably supported about the central shaft of the transmission.
