Abstract:
A hybrid powertrain comprising:a suitable heat engine having rotational output and a direction of rotation;a multi-speed transmission having a main shaft rotatably supporting a plurality of ratio gears each having a mechanism for engaging said main shaft, a cluster shaft having a plurality of ratio gears drivingly connected therewith and meshing with respective ones of the ratio gears on said main shaft, said ratio gears on said cluster shaft and said main shaft cooperating to provide a plurality of gear ratios between said cluster shaft said main shaft in one rotary direction;a selectively engageable input clutch mechanism disposed to selectively connect said engine with said cluster shaft to enforce forward rotation of said main shaft when said engine is inputting rotation to said cluster shaft,a motor/generator continuously drivingly connected with said cluster shaft to selectively deliver power thereto and to receive power therefrom said motor/generator being driven in a direction of rotation opposite to said engine direction to enforce reverse rotation of said main shaft when one of said ratios is established between said cluster shaft and said main shaft;a gear train drivingly connected with one of said ratio gears on said cluster shaft;a selectively engageable clutch and drive mechanism drivingly connected with said gear train; andan accessory mechanism selectively driven by said drive mechanism through said selectively engageable clutch when said one ratio gear is driven by either said engine or said motor/generator.
