Title:
DUAL CLUTCH DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/025348
Kind Code:
A1
Abstract:
The present invention relates to a nested wet dual clutch device. A carrier hub has a flange part extending in a radial direction from the outer peripheral surface thereof. The flange part has a hub-axial extended part extending in an axial direction. A carrier including a first carrier and a second carrier is connected to the flange part through the hub-axial extended part extending in an axial direction. The radii of the hub-axial extended part and a carrier-axial extended part substantially correspond to each other. The outer peripheral surface of a first piston-axial extended part slides along the inner peripheral surface of the carrier-axial extended part in a first compensation chamber, and the inner peripheral surface of the first piston-axial extended part slides along the outer peripheral surface of a rear guide cylinder in a first pressure chamber. The outer peripheral surface of a second piston-inwardly axial extended part slides along the inner peripheral surface of the hub-axial extended part in a second pressure chamber, and the inner peripheral surface of the second piston-inwardly axial extended part slides along the outer peripheral surface of a front guide cylinder in a second compensation chamber.
