Abstract
A transmission includes an input assembly, an electric machine, a variator and a power shift assembly. The input assembly has directional clutches and is configured to receive rotational engine power. The variator has only a single planetary set configured to selectively receive rotational power from the electric machine and from the input assembly. The power shift assembly is configured to receive rotational power from the variator. Power shift clutches are configured to dissipate energy from asynchronous gear meshing and include a first power shift clutch carried by a first countershaft and a second power shift clutch carried by a second countershaft. The power shift assembly is configured to effect multiple different rotational power flows to effect unique gear ratios.
