Title:
LOCK-UP DEVICE OF TORQUE CONVERTER
Document Type and Number:
Japanese Patent JP2016090045
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a dynamic damper device having a simple constitution and capable of suppressing manufacturing costs.SOLUTION: A lock-up device includes an intermediate member 25 to which torque is input from a clutch portion, a driven plate 23 connected to a turbine hub 13, a damper portion for elastically connecting the intermediate member 25 and the driven plate 23, and a dynamic damper device 26. The damper portion has an outer periphery-side damper portion having a plurality of outer periphery-side torsion springs 22 to which the torque is input, and an inner periphery-side damper portion having a plurality of inner periphery-side torsion springs 24 transmitting torque to the driven plate 23. The intermediate member 25 is formed into the annular shape, has a plurality of outer periphery-side engagement portions 25a engaged with the outer periphery-side torsion springs 22 at an outer peripheral portion, and has openings 25c as inner periphery-side engagement portions engaged with the inner periphery-side torsion springs 24 at an inner peripheral portion.SELECTED DRAWING: Figure 2
