Abstract
Building a toroidal continuously variable transmission (CVT) with multiple power rollers arranged in parallel is an effective way to improve its torque capacity. However, that requires a method for synchronizing the operation of all of the power rollers. This paper describes a method of synchronizing the four power rollers in a toroidal CVT that we have researched and developed. It also presents the results of an analysis of the cause of power roller vibration, which was a serious issue encountered in the development process, and describes an effective method for preventing it. The methods described here achieve sufficient synchronization performance for practical use of the toroidal CVT on production vehicles.
