Abstract:
In an infinitely variable ratio transmission having a first conical torque input member and second conical torque output member, wherein said second conical member is oriented with respect to said first conical member such that the axis of rotation of said second conical member is parallel to said axis of rotation of said first conical member and wherein the smaller diameter end of said second conical member is adjacent the larger diameter end of said first conical member, wherein said input torque is transferred from said first conical member to said second conical member by an inelastic, endless belt means the improvement comprising:a) a multiplicity of axially extending channels circumferentially spaced over the external peripheral surface of said conical members, b) a sprocket bar positioned in each of said axially extending channels for engaging said belt means and wherein said sprocket bars are free to move in both the radial and circumferential directions within said channel, c) resilient means positioned between said sprocket bars and their associated channel bottom whereby said sprocket bar is biased radially outward from said conical member.
