Abstract

A torque transmitting body for continuously variable power transmissions of the type in which oppositely convergent, cone-like rolling surfaces of revolution about one axis are retained in torque transmitting rolling frictional engagement at two points of contact with complementing rolling surfaces of revolution about another axis inclined with respect to and intersecting the axis of the cone-like surfaces. The body includes a pair of oppositely convergent cone members telescopically interconnected at their base or large ends for relative rotary and axial movement. A cam assembly is included and acts between the cone members to develop an axial separating force in response to a torque differential between the cone members. Although both cone members are driven at equal speeds, only one is connected to an output torque load so that the torque differential caused by the load may be converted to an axial separating force on the cone members by the camming assembly.
