Abstract

The invention relates to a nested wet dual clutch device. The carrier hub has a flange portion extending in a radial direction from an outer circumferential surface thereof. The flange portion has a hub axial extension extending in an axial direction. A carrier including a first carrier and a second carrier is connected to the flange portion by a hub axial extension extending in an axial direction. The radii of the hub axial extension and the carrier axial extension substantially correspond to each other. An outer circumferential surface of the first piston axial extension slides along an inner circumferential surface of the carrier axial extension in the first compensation chamber, and an inner circumferential surface of the first piston axial extension slides along an outer circumferential surface of the rear guide cylinder in the first pressure chamber. The outer circumferential surface of the second piston inward axial extension slides along the inner circumferential surface of the hub axial extension in the second pressure chamber, and the inner circumferential surface of the second piston inward axial extension slides along the outer circumferential surface of the front guide cylinder in the second compensation chamber.

Description

technical field [0001] This document discloses a dual clutch device, and more particularly, relates to a nested wet dual clutch device. Background technique [0002] The dual clutch device is installed between an engine and a transmission, and is configured to control power of the engine transmitted to the transmission. [0003] Depending on whether lubricant is used, dual clutch devices can be classified as dry or wet. Based on the arrangement of the first clutch assembly and the second clutch assembly, the wet dual clutch device can be divided into a nested type and a parallel type. In addition, based on the method of operation, wet dual clutch devices can be classified into piston type and concentric slave cylinder (CSC) type. [0004] Piston double clutch devices require a pressure chamber for moving the piston in one direction and a compensation chamber for moving the piston in the opposite direction. [0005] The piston dual clutch arrangement may comprise a first p...
