Abstract
Methods and systems for a multi-ratio gear box and a countershaft power-shift transmission are provided. The system contains one or more electric motors coupled to a transmission housing in such that the electric motor does not exceed the highest point of the transmission. A first shaft may be coupled to one or more input speed reduction gear sets. A second shaft may be coupled to a multi-range clutch allowing two speeds. A third shaft may be coupled to a low-speed clutch and a fourth shaft may be coupled to a high-speed clutch, together doubling the number of speeds. The high and low speed clutches provide a large gear spread that allow the twin range clutches to have a reduced gear spread, overall reducing the required size of the transmission system.
