Embodiment Construction

[0035] Identical parts are provided with the same reference numerals in the description of the figures. figure 1 An example of a friction clutch 1 designed as a double clutch is shown. The friction clutch has a double-layered center plate 2 and a first pressure plate 3 and a second pressure plate 4 . The double-layered center plate 2 is composed of a first center plate member 5 and a second center plate member 6 . Here, the first pressing plate 3 and the second pressing plate 4 are designed to be axially movable relative to the rotation axis d, so that the first pressing plate 3 can be pressed between the central plate 2 and the first pressing plate 3. The clutch driven disc arrangement 26 and the second clutch driven disc arrangement 27 are pressed between the center plate 2 and the second pressure plate 4, so that on the one hand the first pressure plate 2 with the first friction lining can be The frictional connection is established between the first clutch disk arrangeme...

Abstract

The friction clutch (1) of the present invention is especially suitable for the powertrain system of a motor vehicle, for coupling the input shaft with the first output shaft and / or the second output shaft, with a double-layered center plate (2 ), a first pressing plate (3) for pressing the first clutch driven plate device between the first pressing plate (3) and the center plate (2) At least one first friction plate (28) of (26) can move axially, and a second pressing plate (4), the second pressing plate (4) in order to be in contact with the second pressing plate (4). At least one second friction plate (29) of the second clutch driven plate device (27) is pressed between the center plates (2) and can move axially, wherein, through the first (3) and the The axial movement of the second pressing plate (4) can be achieved between the friction surfaces (30, 42) of each pressing plate (3, 4) and the friction plates (28, 29) of each clutch driven disc device (26, 27). ) and cancel the frictional connection between the friction plates (28, 29) of each clutch disc device (26, 27) and the friction surfaces (43, 44) of the center plate (2), which Characterized by at least one of the following elements: the first friction surface (30) of the first pressing plate (3), the second friction surface (42) of the second pressing plate (4) and the center At least one friction surface (43, 44) of the plate (2) is designed with at least one groove (7, 15), the groove respectively extending from the inner edge (31) of each friction surface (30, 42, 43, 44) ) extends to the outer edge (32) of the respective friction surfaces (30, 42, 43, 44).

Description

technical field [0001] The invention relates to a friction clutch designed as a double clutch, which is particularly suitable for the powertrain system of a motor vehicle. Background technique [0002] Dual clutches are considered known. Such a double clutch in a three-mass design is known, for example, from DE 10 2017 102 732 A1 with a central plate and two axially displaceable pressure plates. Such dual clutches often suffer from durability problems due to the abrasive particles formed and thermal problems, as the frictional heat formed cannot be dissipated quickly enough. [0003] The task of the present invention is therefore to at least partially overcome the problems known from the background art and in particular to provide a dual clutch that is improved in terms of abrasive particle emission and thermal characteristics. SUMMARY OF THE INVENTION [0004] Said task is solved with the present invention. Further advantageous configurations of the invention are given...
