<p><P>PROBLEM TO BE SOLVED: To provide a driving force distributing device for restraining deterioration in oil, by improving cooling performance under a condition of a large calorific value of a clutch, and quickly raising the temperature of the clutch under a low outside temperature condition. <P>SOLUTION: This driving force distributing device includes a case 13a for journaling an input shaft and an output shaft, a first friction clutch for transmitting torque between the input shaft and the output shaft, a second friction clutch for adjusting transmission torque of the first friction clutch, a cam mechanism for transmitting thrust force of the second friction clutch to the first friction clutch, a housing 24 for arranging the cam mechanism and the second friction clutch inside, a space 84 for receiving oil O flowed out of an outflow port of the housing 24 by contacting with an outside surface of the housing 24 and imparting kinetic energy in the rotation direction to the oil O when rotating the input shaft, and a circulating passage for introducing the oil O of the space 84 to an inflow port of the housing 24 by using the kinetic energy. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
