Embodiment Construction

[0014] figure 1 A first exemplary embodiment of an axial wet dual clutch is shown, in which the torque from the drive motor is transmitted to the clutch hub, optionally via a torsional vibration damper, for example a dual mass flywheel (ZMS). The clutch hub 1 is supported on a ( figure 1 (not shown) housing that encloses a clutch bell in which the dual clutch assembly 3 is housed. The clutch bell, which accommodates the clutch 3 , is sealed from the environment by a sealing device 4 . The clutch bell is here generally formed by a recess (not shown separately) in the transmission housing. The clutch hub 1 is connected to a clutch housing 5 comprising a substantially radially extending entrainment region 5a and a substantially axially extending cylindrical region 5b with respect to the main axis of the dual clutch 3 and a radially extending connection - and the support area 5c. The connection and support region 5c is rotationally fixed and preferably also axially fixedly con...

Abstract

The invention provides wet dual clutch comprising a first single clutch and a second single clutch and further comprises a clutch shell connectable to a driver and two piston cylinder units. The clutch shell is connected with a first transmission input shaft through an output friction plate carrier of the first single clutch and is connected with a second transmission input shaft through an output friction plate carrier of the second single clutch. The piston cylinder unit of each single clutch is radially disposed in a friction plate set of the single clutch and at least partially overlaps the friction plate set in the axial direction. The piston cylinder unit of each single clutch comprises an actuating piston, a pressure cavity and a fleeing oil chamber. Each clutch is supported on a transmission shell through a stator support. The dual clutch also comprises a first conveying device and a second conveying device hydraulically separated from the first conveying device. The first conveying device supplies cooling coil to the second single clutch and the fleeing oil chamber of the second single clutch simultaneously and the second conveying device supplies cooling coil to the first single clutch and the fleeing oil chamber of the first single clutch simultaneously.

Description

technical field [0001] The invention relates to a wet dual clutch comprising single clutches arranged axially one behind the other and hydraulically actuated for a dual clutch transmission in a drive train of a vehicle, comprising a first single clutch axially arranged on the drive side K1 and the second single clutch K2, which is arranged axially on the transmission side; consists of a clutch housing which can be connected to the drive and two piston-cylinder units, the clutch housing has a suspension for the input disks of the two single clutches area or connected to the suspension area, the clutch housing can be connected to the input shaft of the first transmission via the output disk carrier of the first single clutch K1 which is arranged inside relative to the disk pack of the first single clutch K1 and via the second The output friction plate carrier of the single clutch K2, which is arranged inside relative to the friction plate set of the second single clutch K2, is c...
