トルクコンバータ用のロックアップ装置
Document Type and Number:
Japanese Patent JP5688113
Kind Code:
B2
Abstract:
A lock-up device having multistage torsional characteristics includes a retaining plate, a driven plate, a plurality of pairs of outer peripheral side torsion springs configured to elastically couple the both plates, a support plate and a plurality of inner peripheral side torsion springs. The support plate is rotatable relative to the retaining plate and the driven plate, and causes the outer peripheral side coil springs in each pair to act in a series-like manner. Each inner peripheral side torsion spring has a length shorter than that of each outer peripheral side torsion spring. Additionally, the support plate is configured to be restricted from rotating relative to the driven plate when stopper parts of the support plate contact intermediate stopper parts of the driven plate.
