Abstract
An infinitely variable transmission comprising a belt and sheave assembly, the input of which is adapted to be connected to an engine, a hydrokinetic unit, and a torque splitter gear unit located between the torque output portions of the belt and sheave assembly and the input member of the hydrokinetic unit, the output member of the hydrokinetic unit being connected to a driven shaft through final drive gearing whereby only a portion of the torque is transferred hydrokinetically through the hydrokinetic unit thereby increasing the operating efficiency by avoiding hydrokinetic losses and improving smoothness in the ratio changes.
