TOROIDAL CONTINUOUSLY-VARIABLE TRANSMISSION AND CONTINUOUSLY-VARIABLE SPEED CHANGE UNIT

摘要

PROBLEM TO BE SOLVED: To prevent a reduction in life and unstable speed change motions caused by an excessive slip on a rolling contact section (traction section).

SOLUTION: A tilt rotating sensor 56 detecting an amount of tilt rotation of each power roller 7 is arranged on each power roller 7. The amount of tilt rotation of each power roller 7 is determined whether it is appropriate from the amount of tilt rotation of each power roller 7 calculated from a detected signal of each tilt rotating sensor 56. When determining that the amount of tilt rotation of each power roller 7 is inconsistent and an excessive slip is generated on the rolling contact section (traction section), countermeasures for reducing this excessive slip are applied on the basis of the determined results.
