Title:
POWER TRANSMISSION DEVICE AND LOCK-UP DEVICE OF TORQUE CONVERTER
Document Type and Number:
Japanese Patent JP2016125511
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To inhibit rotational speed fluctuation transmitted to a transmission at a power transmission device, such as a lock-up device of a torque converter, more effectively.SOLUTION: A power transmission device includes: a drive plate 25 to which power is input; a hub flange 30 which outputs power; an outer peripheral side torsion spring 26; a float member 27; and a dynamic vibration absorber 31. The outer peripheral side torsion spring 26 connects the drive plate 25 to the hub flange 30 so that the drive plate 25 and the hub flange 30 may rotate relative to each other. The float member 27 may rotate relative to the drive plate 25, the hub flange 30, and the outer peripheral side torsion spring 26 and slides relative to the outer peripheral side torsion spring 26 during the rotation. The dynamic vibration absorber 31 has pendulums 50 which are connected to the float member 27 and move relative to the float member 27 during the rotation of the float member 27.SELECTED DRAWING: Figure 1
