Abstract
A hybrid transmission device includes six planetary gear sets mechanically-operatively connected to an internal combustion engine and two motor/generators adapted to selectively transmit mechanical power to an output member through selective application of eight caliper brake systems. Each planetary gear set has a sun gear and a ring gear, each of which meshingly engage a plurality of planet gears. The first and second motor/generators are coaxially aligned with each other as well as six planetary gear sets. The sun gear in the first planetary gear set is connected to the first motor/generator. The sun gear in the second planetary gear set is connected to the second motor/generator. Various driving modes are provided by changing the states of the caliper brake systems and the operating modes of the engine and the first and second motor/generators.
