Title:
DYNAMIC DAMPER DEVICE AND LOCK-UP DEVICE OF TORQUE CONVERTER
Document Type and Number:
Japanese Patent JP2015083847
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress the generation of noise and wearing at each part when an inertia member is largely contacted in a dynamic damper device.SOLUTION: A dynamic damper device is equipped with a damper plate portion 45, an inertia ring 46, and a damper mechanism 48. The damper plate portion 45 is coupled to an intermediate member 34. The inertial ring 46 is disposed so as to relatively rotate with the damper plate portion 45 in a twist angle area in a predetermined range. The damper mechanism 48 has low stiffness twist characteristics in a low twist angle area with the damper plate 45 and the inertial ring 46, and high stiffness twist characteristics with higher stiffness than the low stiffness twist characteristics in a high twist angle area larger than the low twist angle area. The damper plate portion and the inertia ring 46 are elastically coupled in a rotating direction.
