Description

Traditionally, the gear ratio in scooter CVTs is changed by the in-and-out rolling movement of the roller weights. With the innovative Dr. Pulley sliding roller weights, the roller weights “slide” inward and outward in the Movable Drive Pulley (MDF) to change/extend the gear ratio.
Dr. Pulley sliding roller weights provide the following advantages over traditional “rolling” roller weights:
Eliminate abnormal wear in the high gear position.
Enjoy a broader range of gear ratios.
Experience outstanding acceleration and re-acceleration properties.
Retain explosive low end acceleration and reach higher top speeds.
Last longer than traditional roller weights while experiencing excellent CVT variator performance.
U.S. patent no. 7276004.
