Embodiment Construction

[0019] figure 1 A dual clutch 100 is shown especially for use on a drive train of a vehicle. The input side 110 , the first output side 115 and the second output side 120 are arranged rotatably about the axis of rotation 105 . In the illustrated embodiment, an optional damper 125 is connected to the input side 110 , which can be designed, for example, as a dual-mass flywheel.

[0020] Dual clutch 100 includes a first clutch 130 and a second clutch 140 , which are arranged radially offset in the present embodiment. The two clutches 130, 140 are substantially identical in construction. Among them, representatively, only the first clutch 130 will be discussed in detail below. In this case, the reference numerals of the elements of the clutches 130 , 140 are preceded by the reference numerals of the corresponding clutches 130 , 140 .

[0021] The first clutch 130 includes a first disk set 130 . 1 for torque transmission between the input side 110 and the first output side 115 ...

Abstract

A double clutch comprises an input side, a first output side and a second output side which are rotatably mounted about an axis of rotation. The input side is located on a first axial side and the output sides on an opposite second axial side of the double clutch. Furthermore, a first clutch is provided with a first disk pack for the torque-locking connection of the input side with the first output side and a second clutch with a second disk pack for the torque-locking connection of the input side with the second output side. Two concentric cylinders with circular ring-shaped cross-sections are arranged on a support element, and pistons are arranged in the cylinders, which pistons are adapted to apply axial actuating forces to the clutches, the actuating forces being directed from the first axial side to the second. In order to support the support element with respect to the input side, a rolling bearing is also provided, which lies in an axial region of one of the disk packs.

Description

technical field [0001] The invention relates to a double clutch. In particular, the invention relates to a dual clutch for use in a drive train of a vehicle. Background technique [0002] Dual clutches can be used in the driveline of a vehicle to selectively transfer torque provided by the drive motor to the first or second input shaft of the transmission. In one embodiment, the clutches are radially offset about an axis of rotation about which the input shaft and the two output shafts are also rotatable. Each clutch is associated with a hydraulic actuating device comprising a cylinder and a piston received axially movable in the cylinder. In this case, the piston cross-section is circular, and the two pistons are arranged concentrically around the axis of rotation. The cylinder is mounted on a housing component which is usually supported with respect to the input side by means of rolling bearings. [0003] Usually, the input side of the dual clutch is on a first axial s...
