CONTINUOUSLY-VARIABLE NON-SLIP TRANSMISSIONS

摘要

A continuously-variable transmission includes a pair of axially-displaceable rotary members which are rotatable together about a rotary axis and carry a plurality of coupling elements radially displaceable with respect to the rotary axis to define an effective coupling surface of circular configuration having a diameter varying with the radial positions of the coupling elements. A closed loop link chain is wound around the effective coupling surface of the rotary members and carries a plurality of coupling elements effecting a non-slip coupling with the coupling elements of the rotary members. The rotary members have outer conical surfaces, and the closed loop link chain has contact surfaces bearing against the outer conical surfaces of the rotary members for continuously supporting the closed loop in the circular configuration of the effective coupling surface of the rotary members where wound around the rotary members.
