Abstract:
1. A continuously variable transmission comprising: a primary pulley including: a secondary pulley connected with the primary pulley by a belt, the secondary pulley including: wherein at least one of the primary and secondary pulleys includes: wherein the axially fixed wall is placed axially between the bearing and the movable sheave of the corresponding pulley, wherein the axially fixed wall comprises a first extending portion radially extending in a form of a disc from the corresponding rotation shaft to a radially outer end of the first extending portion, and a second extending portion extending in a form of an annular ring from the radially outer end of the first extending portion toward a corresponding movable sheave side, wherein an outer radius of the bearing is larger than a radius of the radially outer end of the first extending portion, wherein the continuously variable transmission further comprises: wherein the axially fixed wall extends radially up to an inner circumference of the movable cylinder to define the cylinder chamber of the corresponding pulley, and wherein an axial position and a radial position of the connecting portion of the support member is offset from an axial position and a radial position of the outer ring support portion of the support member.
