System for manipulating a continuously variable transmission

摘要

A shifter for use with a continuously variable transmission includes a grip portion and a hub portion. Specifically, the shifter is designed for use on a bicycle, but could also be used with any light vehicle. The grip portion is characterized by a rotatable adjuster that is coupled to a cable. The cable is also coupled to a hub portion. As the adjuster is rotated, the cable is pulled, in turn rotating a pulley assembly in the hub portion. As the pulley assembly is rotated, it advances a rod within a continuously variable transmission. The rod adjusts the power adjusters as described above. The grip portion is also unique in its display of information to the rider. The grip portion includes a display showing the ratio of input to output. The display also includes a filament that curves as the ration is adjusted. A high ratio renders the filament flat while the filament takes on a steep curve as the ratio is adjusted to make riding up hills easier.

1. A shifter for use with a continuously variable transmission (CVT), the shifter comprising:
a display having a filament that is moveable from a first position to a second position, the filament comprising a flexible member, at least a portion of the flexible member visible within the display; a scale for indicating a range of operating conditions for the CVT; and wherein a flexion in the visible portion of the flexible member relative to the scale corresponds to a continuously variable adjustment of the CVT.
