US Patent 11052747 Multi-mode powertrains

A powertrain has an engine, a continuously variable power source (CVP), an output shaft and a transmission configured to provide selection between a plurality of transmission modes. The transmission includes a variator, with first and second output members, that is operably connected to the engine and the CVP and forward, reverse, first speed and second speed transmission components, each having an engaged position and a disengaged position. The transmission configured to provide at least first and second forward transmission modes and a reverse transmission mode in each of which combined power from the engine and the CVP rotates the output shaft. The forward, first speed and second speed transmission components are substantially coaxial with the output members of the variator.
