摘要： A torque transmission device (30) is provided wherein a rotary housing (32) is connected to one of front (12) and rear drive shafts (20) which respectively drive front and rear axles of a four-wheel drive vehicle, while a rotary shaft (20) coaxially carried by the rotary housing (32) is connected to the other of the front and rear drive shafts (12,20). The housing receives therein a multiple disc clutch device (40) for transmitting rotational power between the housing (32) and the shaft through friction engagement between alternately arranged outer and inner clutch discs (37,38) which are respectively rotatable bodily with the housing (32) and the shaft. The housing also receives an axially movable piston (36) to press the clutch discs (37,38) for friction engagement. An end wall of the housing (32) or an end cap (31) secured thereto and a facing end surface of the piston (36) define an axially narrow circular chamber, within which a rotor (41) with several radially extending blade portions is received to be rotated by the shaft. A several space sections into which the chamber (42) is divided by the rotor blade portions are filled with silicon oil of a high viscosity.
