PROBLEM TO BE SOLVED: To provide a control device of a driving force transmission device capable of transmitting power in a state that a driving side and a driven side are synchronized.SOLUTION: A driving force transmission device 10 includes an input shaft 12 and an output shaft 14 coaxially disposed, an elastic member 18 connected to the output shaft 14 at one end and disposed in its shaft circumferential direction, a vibrator 20 connected to the other end of the elastic member 18 and reciprocated in the shaft circumferential direction of the output shaft 14 in accompany with expansion and contraction of the elastic member 18, a clutch member 22 for engaging the vibrator 20 with the input shaft 12 when their angular speeds are equal to each other, and a brake member 24 for engaging the vibrator 20 with a fixing portion 17 when angular speeds of the vibrator 20 and the output shaft 14 are equal to each other. A control portion 19 controls output torque obtained from the output shaft 14 by controlling engagement and disengagement timings of the clutch member 22 and the brake member 24.SELECTED DRAWING: Figure 1 |
