Description

BRIEF SUMMARY OF THE DRAWINGS

[0015] Further advantages, features and details of the present disclosure arise from the description below in which various exemplary embodiments are described in detail with reference to the drawing. The drawings show:

[0016] FIGS. 1 to 7 simplified depictions each of two support segments which are arranged on a plate carrier to form a segmented support element, and

[0017] FIG. 8 a plate carrier designed as an inner plate carrier and on which, radially outwardly, a total of six support segments are attached which are indirectly connected together solely via the plate carrier.

DETAILED DESCRIPTION

[0018] FIGS. 1 to 7 each show in top view two support segments 1, 2 of identical design. The support segment 1 comprises an inner radius 3 and an outer radius 4. At the side, the support segment 1 is delimited by two straight abutting edges 110, 111.

[0019] The right-hand abutting edge 111 shown in FIG. 1 faces an abutting edge 112, also designed as a straight line, of the support segment 2. To form a support element, the support segments 1, 2 are positioned such that they bear against each other with their mutually facing abutting edges 111, 112.

[0020] Depending on design, the abutting edges 111, 112 of the support segments 1, 2 may also be slightly spaced apart from each other in mounted state, as shown in FIG. 8.

[0021] The support segment 1 is formed as a punched part from a suitable sheet metal material. A total of six friction lining elements 5 to 10 are arranged on the support segment 1. The friction lining elements 5 to 10 are designed and arranged on the support segment 1 so that radial grooves result between individual friction lining elements 5 to 10.

[0022] In addition, the friction lining elements 5 to 10 may be provided with a specific structure, in particular grooving. The grooves between the friction lining elements 5 to 10 and the optional structure of the friction lining elements 5 to 10 serve to improve clutch cooling in operation of the friction clutch, in particular in a wet-running clutch system.

[0023] To form various form-fit geometries 101 to 107, inner toothings 19; 29; 39; 49; 59; 69; 79 are formed on the support segments 1, 2. To create a form fit with undercuts, the inner toothings 19; 29; 39; 49; 59; 69; 79 each comprise a total of six teeth 11 to 16; 21 to 26; 31 to 36; 41 to 46; 51 to 56; 61 to 66; 71 to 76 which are formed on the support segment 1.

[0024] In the exemplary embodiment shown in FIG. 1, the teeth 11 to 16 each have the form of an isosceles trapezium. The teeth 11 to 16 taper radially inwardly. The two teeth 11 and 16 arranged at the ends of the support segment 1 each have a passage hole 17, 18.

[0025] The passage holes 17, 18 serve for stable fixing of the support segment 1 to a plate carrier. To fix the support segment 1 to the plate carrier, the teeth 11 and 16 are for example pressed onto a structure of the plate carrier, such that a fixing element protruding from the plate carrier extends through the passage hole 17; 18 of the respective tooth 11; 16.

[0026] In the exemplary embodiment shown in FIG. 2, all the teeth 21 to 26 have a passage hole 27. In the same way, the associated plate carrier is provided with a total of six protrusions onto which the teeth are pressed such that the protrusions engage in or through the respective passage hole 27. The engagement of the protrusions in the respective passage hole 27 creates a form-fit connection with an undercut.

[0027] In the exemplary embodiment shown in FIG. 3, the teeth 31 to 36 each have an oblique edge 38 which serves to create an undercut on form-fit connection of the support segment 1 to an associated plate carrier. All teeth 31 to 36 are designed identically. This simplifies production of the support segment 1.

[0028] In the exemplary embodiment shown in FIG. 4, all teeth 41 to 46 of the support segment 1 have the form of a circle. A segment is cut away from the circle at the point at which the respective tooth 41 to 46 is integrally connected to an arcuate base body of the support segment 1. The circular forms of the teeth 41 to 46 serve to create undercuts on form-fit connection of the support segment 1 to a plate carrier (not shown in FIG. 4).

[0029] In the exemplary embodiment shown in FIG. 5, the teeth 51 to 56 are formed substantially T-shaped on the support segment 1. A crossbar of the T-shaped form of the teeth 51 to 56 is arranged radially inwardly and serves to create undercuts on form-fit connection of the support segment 1 to a corresponding plate carrier.

[0030] In the exemplary embodiment shown in FIG. 6, the teeth 61 to 66 are formed so as to be substantially L-shaped. The L-shaped form of the teeth 61 to 66 serves to create undercuts on form-fit connection of the carrier segment 1 to a corresponding plate carrier. An angled arm of the L-shaped form constitutes a lug extending in the circumferential direction.

[0031] In the exemplary embodiment shown in FIG. 7, the teeth 72 to 75 are formed in the same way as teeth 12 to 15 in the exemplary embodiment shown in FIG. 1. The teeth 71 and 76 in the exemplary embodiment shown in FIG. 7 are formed in the same way as the teeth 31 to 36 in the exemplary embodiment shown in FIG. 3. Thus only the teeth 71 to 76 serve to create undercuts on form-fit connection of the support segment 1 to the corresponding plate carrier.

[0032] FIG. 8 shows in top view a plate 80 with a support element 88. The support element 88 comprises a total of six support segments 81 to 86. The support segments 81 to 86 are connected by form fit to a plate carrier 90 configured as an inner plate carrier.

[0033] The inner plate carrier 90 is configured for example as a sheet metal part with an outer toothing which is complementary to an inner toothing 99 of the support element 88. To form the inner toothing 99 of the support element 88, the support segment 86 comprises a total of six teeth 91 to 96, in a similar fashion to the support segment 1 in FIGS. 1 to 7.

[0034] The teeth 91 to 96 have the form of isosceles trapeziums. The isosceles trapeziums of the teeth 91 to 96 however widen radially inwardly, in contrast to the exemplary embodiment shown in FIG. 1.

[0035] In this way, undercuts can be formed when the inner toothing 99 of the support segments 81 to 86, forming form-fit geometries 98, is brought into engagement with the outer toothing of the plate carrier 90, forming a complementary form-fit geometry 100.
