Toroidal type continuously variable transmission

摘要

In order to stabilize an operation for changing a speed change ratio, and to improve transmitting efficiency and endurance of structural parts of a toroidal continuously variable transmission, a relationship between the switching of a control valve and displacements of trunnions is such that initiation of the displacement of a trunnion having a feedback mechanism including a precess cam and a link arm is effected prior to initiation of the displacement of a trunnion not having a feedback mechanism.
