    Abstract: A variety of transmission mechanisms are provided that include 'radially inverted' pulleys that are nested within each other or otherwise overlap in order to exert 'inward' forces onto a compressive belt that transmits power between the pulleys. By exerted forces 'inward' onto the belt, the belt can be subjected to net compression everywhere along its length. This allows the belt to be less complex and to have a lower cost than belts of transmissions that exert forces 'outward' from pulleys onto a belt, thus requiring expensive and technically challenging belt packs or other elements to sustain the longitudinal tensions experienced by such belts, even when such belts are operated as "push" belts. Transmissions that include such 'radially inverted' pulleys can exhibit reduced size and cost and increased power capacity compared to transmissions that employ 'non-radially inverted' pulleys.

    Abstract: A drive clutch having an engine braking feature for a continuously variable transmission is provided. The drive clutch includes a post that is coupled to an output of an engine. A fixed sheave, coupled to the post, has a fixed sheave belt engagement face. A movable sheave assembly that includes a movable sheave belt engaging face, is configured to move axially on the post to move the movable sheave belt engaging face in relation to the fixed sheave belt engaging face depending on a rotational speed of the drive clutch. An idler bearing is mounted on the post at least in part between the movable sheave belt engaging face and the fixed sheave belt engaging face. The idler bearing includes a one-way rotational assembly and has an outer belt engaging surface with outward extending cogs configured to engage teeth of a belt to prevent slippage during engine braking.
