Infinitely variable transmission

摘要

In a neutral N control for substantially equalizing axial forces to act on two pulleys (7, 9), a belt type continuously variable transmission CVT (11) self-converges into the gear neutral point (GN) at which the output shaft RPM (2) takes the value 0. When the convergence is made to the GN point to establish a no-load state, the CVT establishes a force FA to converge into a pulley ratio of 1.0, in which it is stabilized by itself. A converging force FN to the GN point and the force FA toward the pulley ratio of 1.0 are repeated in a vortex shape in the load state and in the no-load state to establish a creep force. This creep force can be modified by generating a force FO against the force FA.
