Abstract
A two-mode, compound-split, electro-mechanical transmission that selectively receives power from an internal combustion engine as well as a source of electrical energy. Three power receiving planetary gear subsets, first and reverse mode selecting planetary gear subsets, a steering planetary gear subset and left and right output planetary gear subsets are employed. A steering mechanism operates a steering motor. Torque transfer devices selectively ground components of the first and second mode selecting planetary gear subsets. The left and right output planetary gear subsets present corresponding out shafts. The left and right output planetary gear subsets are connected to each other by a shaft which assures simultaneous rotation of one component in the left and right output planetary gear subsets. Another component of the left and right output planetary gear subsets are connected to each other by a retro-rational gear shaft assembly.
