Title:
TORQUE CONVERTER LOCK-UP DEVICE
Document Type and Number:
Japanese Patent JP2015098930
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To increase an amount of inertia of a dynamic damper device without increasing the size of a torque converter.SOLUTION: A dynamic damper device 31, which is provided in an intermediate member 54, includes a damper plate 71; an inertia ring 72; and a plurality of coil springs 75. The inertia ring 72 is arranged axially opposed to an outer circumference of the damper plate 71 and is rotatable relatively to the damper plate 71. The coil springs 75 elastically couple the outer circumference of the damper plate 71 to the inertia ring 72 in a rotational direction. A ratio of outside diameter of the inertia ring 72 to torus outside diameter of a torque converter main body is not less than 1 and not more than 1.5. Furthermore, the inertia ring 72 and the coil springs 75 are partially arranged at axially overlap positions with a turbine 4.
