Title:
LOCK-UP DEVICE OF TORQUE CONVERTER
Document Type and Number:
Japanese Patent JP2015014363
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a dynamic damper device reduced in its dimension and weight.SOLUTION: A lock-up device includes a clutch portion 28, a driven plate 33, a plurality of torsion springs 29, 32, an intermediate member 31, and a dynamic damper device 34. The clutch portion 28 transmits torque from a front cover 2 to an output side, and the driven plate 33 is connected to a turbine 4. The intermediate member 31 is rotatable relatively to the clutch portion 28 and the driven plate 33, to operate at least two of the plurality of torsion springs 29, 32 in series. First and second inertia rings 53, 54 constituting the dynamic damper device 34 have storage recessed portions 53a, 54a axially divided and axially opposed to each other, and a plurality of coil springs 55 are accommodated in the storage recessed portions 53a, 54a.
