Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2015197178
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To sufficiently suppress torque fluctuation in a low rotation frequency region, and to further lower a lock-up rotation frequency by a torque converter.SOLUTION: A power transmission device is equipped with a fly wheel assembly 2 and a torque converter 3. The fly wheel assembly 2 has a first fly wheel 5 in which power from an engine is inputted, a second fly wheel 6 relatively rotating with the first fly wheel 5, and a damper mechanism 7 elastically coupling the first fly wheel 5 and the second fly wheel 6 in a rotating direction. The torque converter 3 includes a dynamic damper device 61 which has a mass body disposed so as to relatively rotate with a member of a power transmission path during power transmission, and transmits power from the second fly wheel 6 to a transmission.
