ABSTRACT:
A continuously variable transmission incorporating a variator having first and second sheaves of adjustable effective diameter by moving one pulley half axially with respect to another to vary the effective diameter of each sheave for engagement with a flexible drive band has a fixed pulley half of one sheave facing the moveable pulley half of the other sheave to maintain alignment of the drive band in the usual way. Both adjustable pulley halves are operated from adjustment means on the same side of the drive band, one adjustment means being connected through the center of the fixed pulley half to the moveable pulley half and that fixed pulley half being mounted by its outer periphery.
