Title:
LOCK-UP DEVICE OF TORQUE CONVERTER
Document Type and Number:
Japanese Patent JP2016156384
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To achieve low rigidity and a wide angle of a torsional characteristic with a simple configuration in a lock-up device.SOLUTION: The lock-up device includes a drive plate 25, an outer peripheral side torsion spring 26, a driven plate 27, an inner peripheral side torsion spring 28, and an intermediate member 29. The outer peripheral side torsion spring 26 has at least two outer peripheral side springs 26a and 26b arranged side by side in the circumferential direction and acting in series, and the outer peripheral side springs 26a and 26b are arc springs. The inner peripheral side torsion spring 28 has at least two inner peripheral side springs arranged side by side in the circumferential direction and acting in series. The intermediate member 29 is relatively rotatable to the drive plate 25 and the driven plate 27, and allows the outer peripheral side torsion spring 26 and the inner peripheral side torsion spring 28 to act in series.SELECTED DRAWING: Figure 1
