Title:
LOCK-UP DEVICE OF TORQUE CONVERTER
Document Type and Number:
Japanese Patent JP2015014355
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce an axial occupation space and to secure a sufficient inertia amount in a dynamic damper device disposed in a lock-up device.SOLUTION: A lock-up device includes a clutch portion 28, a driven plate 37, a plurality of torsion springs 29, 31, and a dynamic damper device 33. The clutch portion 28 transmits torque from a front cover 2 to an output side. The driven plate 37 is relatively rotatable to the clutch portion 28, and is connected to a turbine 4. A plurality of torsion springs 29, 31 elastically connect the clutch portion 28 and the driven plate 37. The dynamic damper device 33 has inertia rings 46, 47 disposed at an outer peripheral side of the torsion springs 29, 31, and is connected to an intermediate member 30 to attenuate rotational speed fluctuation.
