Embodiment Construction

[0056] discussed Figure 1 to Figure 4 , used to illustrate the prior art.

[0057] Figure 5 and 6 A clutch disc 30 according to the invention is shown in , wherein, Figure 6 shown in enlarged view Figure 5 Part of the area shown in D.

[0058] The structure of the clutch disc 30 according to the present invention is basically similar to image 3 and Figure 4 The structure of a conventional clutch disc is illustrated.

[0059] The clutch disc according to the invention differs from conventional clutch discs essentially in that, in addition to the first hub flange 40, the clutch disc according to the invention also has a second hub flange 41 which is opposite to the It is arranged parallel to and rotationally symmetrical to the first hub flange 40 .

[0060] Depending on the direction of load (pull or push), at least one hub flange 40 , 41 engages on the hub 32 so that torque can be transmitted from the hub flange 40 , 41 to the hub 32 . A spring element 50 is arra...

Abstract

The invention relates to a clutch disc for a friction clutch device and to the friction clutch device itself, and to a drive train. The clutch disc (30) comprises a hub (32) for torque-resistant connection to a shaft; a friction element (33) for frictionally applying a torque to the clutch disc (30); and a first hub flange (40) and a second hub flange (41), wherein at least the first hub flange (40) is connected in a torque-resistant manner to the hub (32). The clutch disc (30) has spring elements (50) which couple the two hub flanges mechanically to each other between same so that the hub flanges can rotate relative to each other. The clutch disc (30) is designed such that the two hub flanges (40, 41) can be offset laterally to each other. By means of the proposed clutch disc, it is possible to compensate a lateral and / or radial offset and / or a radial displacement while ensuring a long service life on account of reduced friction conditions on the damping springs of the clutch disc.

Description

technical field [0001] The invention relates to a clutch disc for a friction clutch arrangement, in particular for a dry clutch, and the friction clutch arrangement itself. Furthermore, the invention relates to a drive train, in particular a drive train of a motor vehicle, which has a friction clutch arrangement according to the invention. Background technique [0002] A clutch disc is known as a component of a clutch or clutch arrangement for transmitting torque between a drive machine and a transmission. Such clutch disks are usually coupled centrally to a shaft (for example, a transmission shaft) and can be acted upon by a correspondingly configured clutch element when the friction linings of the clutch disks arranged on the radially outer side are subjected to an axial force. torque. [0003] For functionality and to ensure a long service life, it is important that the clutch disc is only subjected to as far as possible a theoretically set load during use and thus unde...
