Abstract
A driven unit helix assembly for a continuously variable transmission including a roller sleeve, a helix, a spring, and a helix sleeve. The roller sleeve is configured to coupled to a movable sheave and axially translate along a post. A plurality of roller assemblies radially extend from the roller sleeve and travel within roller tracks of the helix, such that the roller sleeve and helix define coaxial components coupled an axial sliding engagement. The spring extends from a proximal end coupled to a proximal portion of the helix to a distal end configured to contact at least a portion of the distal portion of the movable sheave, thereby urging the movable sheave in the distal direction. The helix sleeve extends circumferentially around the helix and is configured to retain a fluid in the helix assembly.
