Continuously variable transmission
First Claim
1. A support member for components of a continuously variable transmission, the support member comprising:
- a disk having a central hole and an outer circumference;
a plurality of grooves that extend radially from the outer circumference toward the central hole; and
a plurality of concave surfaces that extend radially from the outer circumference toward the central hole, wherein the concave surfaces are angularly interposed between the grooves.

Abstract
A continuously variable transmission is disclosed for use in rotationally or linearly powered machines and vehicles. The single axle transmission provides a simple manual shifting method for the user. An additional embodiment is disclosed which shifts automatically dependent upon the rotational speed of the wheel. Further, the practical commercialization of traction roller transmissions requires improvements in the reliability, ease of shifting, function and simplicity of the transmission. The disclosed transmission may be used in vehicles such as automobiles, motorcycles, and bicycles. The transmission may, for example, be driven by a power transfer mechanism such as a sprocket, gear, pulley or lever, optionally driving a one way clutch attached at one end of the main shaft.
