Embodiment Construction

[0035] In the description of the figures, the same reference numerals are assigned to the same parts. figure 1 An example of a friction clutch 1 designed as a double clutch is shown. The friction clutch has a double-layer central plate 2 and a first pressure plate 3 and a second pressure plate 4 . The two-layer center panel 2 is composed of a first center panel member 5 and a second center panel 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 device 26 and the second clutch driven disc device 27 are compressed between the central plate 2 and the second pressure plate 4, and then on the one hand, the first pressure plate 2, with the first friction plate Establish friction connection between the first clutch driven disc device 26 of 28 and the central...

Abstract

The invention relates to a friction clutch (1), particularly for the drive train of a motor vehicle, for coupling an input shaft to a first output shaft and / or a second output shaft, comprising a double-layer central plate (2), a first pressure plate (3), which can be axially moved in order to compress at least one first friction lining (28) of a first clutch disk arrangement (26) between the first pressure plate (3) and the central plate (2), and a second pressure plate (4), which can be axially moved in order to compress at least one second friction lining (29) of a second clutch disk arrangement (27) between the second pressure plate (4) and the central plate (2), in which a frictional connection between a friction surface (30, 42) of the respective pressure plate (3, 4) and friction linings (28, 29) of the respective clutch disk arrangement (26, 27), and between the friction linings (28, 29) of the respective clutch disk arrangement (26, 27) and a friction surface (43, 44) of the central plate (2), can be produced and released by means of the axial movement of the first (3) and second (4) pressure plates. The invention is characterised in that at least one of the following elements: the first friction surface (30) of the first pressure plate (3); the second friction surface (42) of the second pressure plate (4); and at least one of the friction surfaces (43, 44) of the central plate (2), is embodied with at least one groove (7, 15) which extends respectively from an inner edge (31) of the respective friction surface (30, 42, 43, 44) to an outer edge (32) of the respective friction surface (30, 42, 43, 44).

Description

technical field [0001] The invention relates to a friction clutch designed as a double clutch, especially suitable for use in a powertrain of a motor vehicle. Background technique [0002] Dual clutches are considered known. Such a triple-mass dual clutch with a central plate and two axially displaceable pressure plates is known, for example, from DE 10 2017 102 732 A1. Such double clutches often have durability problems due to the wear particles that develop and thermal problems, since the frictional heat that develops cannot be dissipated quickly enough. [0003] It is therefore the object of the present invention to at least partially overcome the problems known from the prior art and in particular to provide an improved dual clutch with respect to abrasive particle emissions and thermal characteristics. Contents of the invention [0004] This task is solved with the features of independent claim 1 . Further advantageous refinements of the invention are given in the ...
