Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2019163815
Kind Code:
A
Abstract:
To provide a power transmission device capable of more properly suppressing resonance.SOLUTION: A power transmission device 99 includes a clutch portion 6, a turbine 4, a dynamic vibration absorber 15, a rotation sensor 8, and a control portion 13. The clutch portion 6 receives input torque from a driving source and is rotatably disposed. The turbine 4 outputs the torque input to the clutch portion 6 to a driving wheel side. The dynamic vibration absorber 15 is disposed on a power transmission passage including the clutch portion 6 and the turbine 4. The rotation sensor 8 detects a rotational frequency per unit time of the turbine 4. The control portion 13 controls the dynamic vibration absorber 15 to reduce rotational fluctuation on the basis of the rotational frequency of the turbine 4 detected by the rotation sensor 8.SELECTED DRAWING: Figure 1
