Abstract
To provide symmetrically wide inner spaces near two front or rear wheels of an automotive vehicle in which an engine and a transmission are arranged in series in the vehicle transversal direction, a first large-sized viscous coupling is disposed near a small-sized front or rear differential gear to limit the differential motion thereof; and a second small-sized viscous coupling is disposed near a large-sized center differential gear to limit the differential motion thereof. The center differential gear is disposed on the transmission side to differentially distribute engine power to front and rear wheels, and the front or rear differential gear is disposed on the engine side to further differentially distribute engine power distributed by the center differential gear to right and left wheels.
