Title:
LOCK-UP DEVICE OF TORQUE CONVERTER
Document Type and Number:
Japanese Patent JP2016023655
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a lock-up device capable of achieving a large twist angle with a simple configuration.SOLUTION: A device of this invention includes: a piston 24 having a friction material 33; a drive plate 25 connected to the piston 24; a plurality of circular arc-like outer peripheral side torsion springs 26; first and second plates 35 and 36; a plurality of inner peripheral side springs 28; and a first intermediate member 29 and a second intermediate member 30. Torque is transmitted to the drive plate 25, the outer peripheral side torsion springs 26, the first intermediate member 29, the inner peripheral side torsion springs 28, the first and the second plates 35 and 36, and a turbine 4 in this order. The second intermediate member 30 is relatively rotatable to the drive plate 25, the first and the second plates 35 and 36, and the first intermediate member 29, and allows a set of the inner peripheral side torsion springs 28 to act in series.SELECTED DRAWING: Figure 1
