摘要： PROBLEM TO BE SOLVED: To provide a four-wheel drive device offering simple construction permitting highly precise and active control of the transmission distribution of driving force transmitted from an engine to a driving wheel side and a driven wheel side. SOLUTION: The driving force of the engine is input to a driving gear and distributed to right and left wheels on the driving wheel side by a driving wheel side differential gear. A driving wheel side propeller shaft is rotated by engagement between the driving gear and a speed increasing gear and the rotation of the driving wheel side propeller shaft is transmitted to a driven wheel side propeller shaft by a differential mechanism. The rotation of the driven wheel side propeller shaft is input to a driven wheel side differential gear by engagement between a speed reducing gear and the driven gear and distributed to right and left wheels on the driven wheel side. A differential control element of the differential mechanism is rotation controlled by a motor to give relative differential rotation to the driving wheel side propeller shaft and the driven wheel side propeller shaft. Thus, the driving force of the engine is selectively distributed to the driving wheel side and the driven wheel side. COPYRIGHT: (C)2004,JPO
