Abstract
This paper describes a half-toroidal continuously variable transmission (CVT) that has been newly developed. The continuously variable unit (CVU) of this CVT adopts a traction drive as its power transmission principle. The major features of this mechanism include its capacity to transmit large torque, quick ratio changes, and high transmission efficiency in the low torque range. The major CVT performance characteristics and dimensions and features of the various parts of the unit are explained here.
