CONTINUOUSLY VARIABLE TRANSMISSION

摘要

An axial force generation mechanism for a transmission includes a traction ring having a first side, a middle portion, and a second side. The first side includes a set of ramps and the second side includes a traction surface. The axial force generation mechanism also includes a torsion spring having a first end and a second end. The middle portion of the traction ring includes a recess adapted to receive the torsion spring. The axial force generation mechanism also includes a load cam roller retainer having a retainer extension adapted to cooperate with the recess of the traction ring for substantially housing the torsion spring. The retainer extension includes a slit for receiving the second end of the torsion spring.
