ABSTRACT:
When a failure occurs with the electrical system while the car is traveling at low speed, the toroidal continuous variable transmission fixes the transmission ratio to a value on the speed-decrease side, so that the car can start even when the car stops on a slope or it is heavily loaded. Further, when one spool valve is at the neutral position and if one of the trunnions supporting the power rollers should receive a force due to torque variations in the input disk, the other trunnion is not affected at all and not displaced.
