ABSTRACT:
A continuously variable transmission or clutch device (10) includes at least one pulley (18) rotatable on a pivot (28) and having a pair of adjustable sheaves (30, 34) including a movable sheave (30) movable along the pivot. An ortho-planar compliant mechanism (14) is capable of elastic deformation and operatively coupled to the movable sheave to bias the movable sheave towards or away from the other sheave. The ortho-planar compliant mechanism includes a substantially flat configuration and is deflectable therefrom as the movable sheave moves. The ortho-planar compliant mechanism can include a center platform (38) disposed on the pivot and a plurality of arms (42) extending from the platform to distal ends (46) coupled to the movable sheave.
