Abstract

See full text

A power train and related vehicle are described for continuously variable transmission of power. A gear set includes first and second input components and an output component. An engine provides mechanical power to the first input component and, when a clutch device is in a first state, to a first continuously variable power source (“CVP”). With the clutch device in a second state, the first CVP is decoupled from the engine. A second CVP receives non-mechanical power from the first CVP, and converts the non-mechanical power to mechanical power. When a brake device is not engaged, the second CVP provides the resulting mechanical power to the second input component. When the brake device is engaged, the brake device prevents the second input component from rotating.
