| 摘要 |
A differential transmission system including: a first-differential; and a second-differential, wherein the first and second differentials are coupled in series such that the output of the first-differential serves as input to the second-differential. In a first embodiment, power is transmitted from the first-differential to the second-differential by means of a first first-differential output gear and a second first-differential output gear respectively coupled to a first second-differential input gear and a second second-differential input gear. In a second embodiment, power is transmitted from the first-differential to the second-differential by means of a pulley and belt system. In a third embodiment, power is transmitted from the first-differential to the second-differential by means of a sprocket and chain system.
