Abstract: A switchable powertrain comprises at least four points of freedom. The switchable powertrain comprises a main gear set configured for gear ratio selection, the main gear set comprising main gears coupled to a main shaft and second gears coupled to a second shaft. An adapter comprises a first selective coupling configured to selectively couple to the main shaft, and a second selective coupling configured to selectively couple to the second shaft. A first torque source and a clutch are configured for selectively coupling or decoupling first torque to the main shaft. A second torque source is configured for selectively outputting second torque to the first selective coupling or to the second selective coupling.

Abstract: A switchable powertrain includes a main gear set configured for gear ratio selection. The main gear set includes an input shaft, first gears coupled to a main shaft, and second gears coupled to a second shaft. The second gears are meshed with the first gears. The switchable powertrain further includes a first torque source, a second torque source, a clutch configured for selectively coupling the first torque source to the input shaft of the main gear set, and an adapter. The adapter includes a first selective coupling for forming a first adapter torque transfer pathway from the second torque source directly to the main shaft, and a second selective coupling for forming a second adapter torque transfer pathway from the second torque source, through the main gear set, and to the main shaft.
