TRANSMISSION RATIO CONTROL APPARATUS FOR INFINITELY VARIABLE TRANSMISSIONS OF THE TOROIDAL TYPE

摘要

A tilting angle detector detects a tilting angle of the power rollers which perform the transmission operation of a toroidal type infinitely variable transmission. Based on the detecting signal and a command value signal from command value selecting means for selecting a command value of the transmission ratio, control means controls the power rollers to tilt. In this control, correction means corrects at least one of the detecting signal of the tilting angle detector and the command value signal of the command value selecting means so that a relationship of the transmission ratio with respect to the tilting angle becomes linear, and thus the gain at each transmission ratio is made equal.
