Title:
TORQUE CONVERTER LOCK-UP DEVICE
Document Type and Number:
Japanese Patent JP2015098931
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To increase an amount of inertia of a dynamic damper device and effectively suppressing fluctuation in rotational speed without increasing the entire size of a torque converter.SOLUTION: This device includes: a damper plate 71; a pair of inertia rings 72; a first cover member 73; a second cover member 74; and a plurality of coil springs 75. The damper plate 71 is provided in an intermediate member 54. The first cover member 73 is arranged on a front cover side of the damper plate 71 in an axial direction so as to be rotatable relatively to the damper plate 71, and has first inside diameter. The second cover member 74 is arranged opposite to the first cover member 73 across the damper plate 71 and relatively rotatable to the damper plate 71, and has second inside diameter larger than the first inside diameter. The coil springs 75 elastically couple the damper plate 71, the paired inertia rings 72, and the first and second cover members 73 and 74 in a rotational direction.
