Continuously variable transmission
First Claim
1. A mechanism for facilitating the adjustment of a speed ratio of a continuously variable transmission (CVT), the mechanism comprising:
- a shift rod positioned along a longitudinal axis of the CVT, the shift rod having a threaded end;
a cable operationally coupled to the shift rod; and
a handle grip operationally coupled to the cable.

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.

8. A method of adjusting a speed ratio of a continuously variable transmission (CVT), the method comprising:
-
rotating a handle grip; and wherein rotating the handle grip causes; an actuation of a cable; an actuation of a shift rod operationally coupled to the cable, said actuation of the shift rod comprising an axial translation of the shift rod; and an actuation of a sleeve coupled to the shift rod, wherein the actuation of the sleeve comprises an axial translation of the sleeve in a first axial direction when the handle grip is rotated in a first rotational direction. - View Dependent Claims (9, 10, 11, 12, 13)
