The object of the invention is to provide a clutch disc, in particular for use with a motor vehicle clutch, with a drive plate, are secured to the lining support elements, which are biased against each other in the axial direction and which each have at least one lining mounting surface on sides facing away from each other in the axial direction, at the at least one clutch lining is attached to create, which allows an improved axial preload and is inexpensive to produce.

The object is with a clutch disc, in particular for use with a motor vehicle clutch, with a drive plate, are secured to the Belagtrageiemente, which are biased against each other in the axial direction and each have in facing away from each other in the axial direction sides at least one lining mounting surface, at least one Clutch lining is fixed, achieved in that the lining support elements on the lining mounting surface in the axial direction facing away from each side have at least one Belaganlagefläche for a clutch lining, which is opposite to the clutch lining, which is attached to the respective lining carrier. The inventive design of the clutch disc, as described above and below, the mass moment of inertia and the tensioned thickness of the clutch disc can be reduced. The mutually prestressed lining support elements have, in addition to their support function, the function of spring elements, by which the opposite clutch linings are biased against each other. The lining carrier elements according to the invention are thus combined lining carrier and spring elements.

A preferred embodiment of the clutch disc is characterized in that the pad attachment surface is formed by an adhesive surface. Preferably, the adhesive is surface just trained. But it is also possible to attach the clutch linings otherwise, for example by means of rivets, on the lining mounting surface.

A further preferred embodiment of the clutch disc is characterized in that the pad bearing surface is separated from the pad attachment surface by at least one corrugation. The corrugation makes it possible in a simple manner to generate different levels in the axial direction on a covering carrier element.

A further preferred embodiment of the clutch disc is characterized in that the lining mounting surface of a lining supporting element is arranged between two supporting surfaces on which corresponding supporting surfaces of at least one further lining carrier element are supported in the assembled state of the coupling disk. As a result, a high stability of the pad spring effect generated by the lining carrier elements can be achieved.

A further preferred embodiment of the clutch disc is characterized in that a step is formed between the pad attachment surface and the pad bearing surface in the pad carrier. The step makes it possible to guide a lining support element behind a facing in the axial direction lining support element.

A further preferred embodiment of the clutch disc is characterized in that the dimension of the step in the axial direction corresponds approximately to the material thickness of the lining carrier element. This provides the advantage that in the spring-loaded, tensioned state in the area of the succession of lining support elements neither undesirably high stresses nor increased contact with the linings occur.

A further preferred embodiment of the clutch disc is characterized in that the lining carrier elements each have a substantially rectangular recess. In the region of the recess, two covering carrier elements lying opposite each other in the axial direction can be guided one behind the other. The recess may, for example, have the shape of a slot, an aperture or an incision.

Further preferred embodiments of the clutch disc are characterized in that the lining carrier elements in the assembled state of the clutch disc radi- al have inside or outside of the lining mounting surface in each case two tongues, on each of which at least one lining contact surface is provided for the clutch lining, which is opposite to the coupling lining, which is attached to the respective lining carrier element. Preferably, in each case at least one support surface is provided on the tongues, on which a corresponding support surface of a further lining support element is supported in the assembled state of the clutch disk.

A further preferred embodiment of the clutch disc is characterized in that the lining carrier elements in the assembled state of the clutch disc are in each case in engagement with the lining carrier elements which are adjacent in the circumferential direction. As a result, a stable composite of the lining support elements is created in the assembled state of the clutch disc.

A further preferred embodiment of the clutch disc is characterized in that the lining carrier elements each have at least one window, which serves in the assembled state of the clutch disc for receiving the lining contact surface for the clutch lining, which faces the clutch lining, which is fastened to the respective lining carrier. Preferably, the windows are substantially rectangular.

A further preferred embodiment of the clutch disc is characterized in that the lining carrier elements each comprise at least one tongue on which the lining contact surface is provided for the clutch lining, which is opposite the clutch lining which is fastened to the respective lining carrier element. Preferably, the tongues are formed integrally with the covering carrier element.

Another preferred embodiment of the clutch disc is characterized in that all lining support elements have the same shape. As a result, the production of the clutch disc according to the invention is considerably simplified.

Another preferred embodiment of the clutch disc is characterized in that the lining carrier elements have a fastening portion radially inward. The attachment portion includes, for example, a plurality of through holes for receiving - A - of fastening rivets, with the help of which the lining support elements are attached to the drive plate.

Another preferred embodiment of the clutch disc is characterized in that the lining carrier elements are each formed in one piece from spring steel. As a result, a simple production and a good spring action of the lining support elements are ensured.

In Figure 1, a clutch disc 1 is shown in perspective and partially broken. The clutch disc 1 comprises a drive plate 3, which has a central hub 5. The hub 5 has a tooth profile through which the drive plate 3 can be positively and non-rotatably connected to a (not shown) transmission input shaft. The clutch disc 1 is part of a clutch of a motor vehicle whose structure and function are assumed to be known.

Radially outward, the drive plate 3 on a plurality of through holes, which serve to attach lining support elements by means of rivet joints 7, 8 on the drive plate 3. In turn, the lining support elements clutch linings 11, 12 are fastened. The clutch lining 11 has a circumferential groove 14 and a plurality of radial grooves 15, 16. By the circumferential groove 14 and the radial grooves 15, 16 11 segments are formed on the surface of the one-piece clutch lining. The clutch lining 11 may also be designed in several parts.

In Figure 2, a detail of Figure 1 is shown enlarged. In the illustrated detail, the covering 11 is partially removed, so that in the axial direction between the clutch linings 11, 12 prestressed lining support elements 21 to 24 are partially visible. In the context of the present invention, the term refers axially to the axis of rotation of the clutch disc 1. The pad carrier element 22 has a pad attachment surface 26, which is cross-hatched. The pad carrier element 24 has a pad attachment surface 28, which is also hatched crosswise. In this and in the following embodiments For example, all pad attachment surfaces, also referred to as pad attachment sections, are cross hatched. The lining mounting surfaces 26 and 28 are flat and form lining adhesive surfaces, which are also referred to as Belagaufklebeabschnitte and are glued to the parts of the clutch lining 11.

In Figure 3, the clutch disc 1 of Figure 1 is shown in plan view.

FIG. 4 shows the view of a section along the line IV-IV in FIG. In the sectional view it can be seen that the clutch linings 11 and 12 are biased by lining support members 31 to 36 at a predetermined distance from each other. The lining carrying element 32 has a lining adhesive surface 42, to which a part of the coupling lining 11 is glued. In the axial direction adjacent to the covering adhesive surface 42, a covering adhesive surface 43 is arranged, which is provided on the lining carrier element 33 and to which a part of the Kuppiungsbelags 12 is adhered. Adhesive contact surfaces 44 and 45 are adjacent in the circumferential direction to the covering adhesive surfaces 42 and 43. The lining contact surface 44 is formed on the lining carrier element in such a way that the clutch lining 11 rests against the lining contact surface 44. Thus, the clutch lining 12 is fastened to the lining adhesive surface 43 of the lining carrier element 33, the coupling lining 11 located opposite in the axial direction resting against the lining bearing surface 44 of the lining carrier element 33. The pad contact surface 45 is formed on the pad carrier element 34. At the pad bearing surface 45 of the clutch lining 12 is applied. The lining carrier element 34 has a lining adhesive surface 46, to which the clutch lining 11 is glued. Opposite the covering adhesive surface 46, a lining adhesive surface 47 is arranged, to which the coupling lining 12 is glued and which is provided on the lining carrier element 35.

In FIG. 4 it can be seen, starting from the left, that one end of the lining-carrying element 31 bears against the lining-carrying element 32. In addition, the left end of the lining carrier element 33 bears against the lining carrier element 32. The right end of the lining carrier element 32 bears against the lining carrier element 33. The left end of the lining carrier element 34 also rests against the lining carrier element 33. The right end of the lining carrier element 33 bears against the lining carrier element 34. The left end of the lining carrier element 35 also bears against the lining carrier element 34. The right end of the lining carrier element 34 bears against the lining carrier element 35. The left end of the lining carrier element 36 bears against the lining carrier element 35. Thereby is ensured in the assembled state of the clutch disc, a stable composite and a good spring action of the lining support members in the axial direction.

FIGS. 5 to 8 show a covering carrier element 50 of the exemplary embodiment illustrated in FIGS. 1 to 4 in various views. The pad carrying member 50 has a fixing portion 51 which has substantially the shape of a truncated triangle. In the attachment portion 51, two through holes 52, 53 are attached. The through holes 52, 53 serve to pass through fastening rivets, with which the lining-carrying element 50 can be fastened to the driver disk (3 in FIG. 1). From the attachment portion 51 extends in the radial direction, a connecting portion 55 which is formed substantially rectangular. In the context of the present invention, the term is referred to radially on the axis of rotation of the clutch disc (1 in Figure 1). Radially outward, the connecting portion 55 merges into an abutment portion 56, which also has substantially the shape of a rectangle. The contact section 56 has centrally a corrugation 57, which extends in the radial direction. The abutment portion 56 is bounded laterally by two corrugations 57, 58, which are arranged parallel to the corrugation 57. The corrugation 57 forms a contact surface for a clutch lining. The corrugations 58, 59 form on the opposite side in the axial direction support surfaces for at least one adjacent in the axial direction lining support member. Radially outward, the abutment portion 56 on the corrugation 59 merges into a triangular lug 60 bounded by the corrugation 59 and a corrugation 62 which, together with the corrugation 59, has substantially the shape of a Vs. The triangular projection 60 merges into a wing 61 which extends substantially in the circumferential direction. The term circumferential direction also refers to the axis of rotation of the clutch disc (1 in Figure 1). The wing 61 is provided with three corrugations 62-64 which are arranged parallel to each other and at an angle of about 20 degrees to the corrugation 59. The corrugations 61 and 64 define a covering adhesive surface 65. At its free end, the wing 61 has a corrugation 66, which forms a support surface for a further covering carrier element. The corrugations 59, 62 and 58 also form support surfaces for further covering support elements.

Radially inside, two tongues 68, 69 extend from the connecting section 55, each having a corrugation 71, 72. The corrugations 71, 72 form contact surfaces for the clutch lining, which also bears against the corrugation 57. The corrugations 57 and 71, 72, as From the sectional views of Figures 7 and 8, in the axial direction opposite to the covering adhesive surface 65 is arranged.

In FIG. 9 it can be seen that a step 75 is formed on the covering carrier element 50 between the corrugation 59 and the corrugation 63. The height 76 of the step 75 corresponds approximately to the thickness of the lining support element 50. This allows in a simple manner, the assembly with other lining support elements, which are carried out the same as the lining support member 50th

In Figure 10, the covering support member 50 is shown in perspective. In order, as indicated in FIG. 2, to arrange two lining carrier elements 50 in the axial direction one behind the other, the lining carrier 50 has a recess 78 and a slot 79. In FIGS. 1 to 4 it can be seen that identical lining-carrying elements are arranged one behind the other in the axial direction and overlapping in the circumferential direction. The corrugation directions and the covering adhesive surfaces are designed and arranged such that during compression of the lining carrier elements only movements occur which do not generate any shear stresses in the bonding regions. In the area of the level 75 in the amount of the material thickness, a lining carrying element can be guided behind a coating carrier element lying opposite in the axial direction. This has the advantage that in the spring-loaded, tensioned state at the location of the series guide neither high stresses in the lining support elements nor an increased contact pressure to the clutch linings occur. The fact that the transmission-side layer of lining support elements with the flywheel-side lining and the flywheel-side layer of lining carrier elements is adhesively bonded to the transmission-side coupling lining and the lining carrier elements are guided one behind the other means limiting the axial extent of the arrangement similar to that used in conventional double-segment lining suspension guaranteed by step riveting. For this reason, a riveted double-segment pad suspension can also be realized with the padding carrying elements according to the invention, in which simple hollow rivets can be used instead of the stepped rivets. Consequently, the lining thickness required to ensure a certain wear reserve can also be reduced here.

FIG. 11 shows in perspective a covering carrier element 80 according to a further exemplary embodiment. The pad carrying member 80 has a fixing portion 81 having two through holes 82 and 83. From the attachment portion 81 is a section 84th out, which expands radially outward. In the section 84, corrugations 85 to 88 are formed, which extend in the direction of a radial parallel to each other. At its left side, the widening portion 84 is bounded by a corrugation 89 which is inclined at an angle of about 20 degrees to the corrugation 88. From the corrugation 89 goes out a tongue 92 having a lining mounting portion 90. In extension of the corrugation 89, a slot 91 is formed between the tongue 92 and the radially outwardly widening portion 84. In the area of the corrugations 85 and 87, the covering carrier element 80 expands into the plane of the paper. In the region of the corrugations 86, 88, the covering carrier element 80 expands out of the plane of the paper. Likewise, the pad attachment surface 90, also referred to as a pad attachment portion, is axially spaced from the corrugations 87 and 85.

FIG. 12 shows a covering carrier element 100 with a fastening section 101 in perspective. The attachment portion 101 has two through holes 102 and 103. From the attachment portion 101, a portion 104 extends, which widens radially outward. Radially inwardly from the portion 104 on the left side of a tongue 105, which has a pad attachment surface 106. In addition, the portion 104 has a central corrugation 109 extending radially outward. Parallel to the corrugation 109, the pad carrier 100 has corrugations 108 and 110 which laterally delimit the section 104. Radially outward from the section 104 tongues 111 and 112 from. The tongue 111 is provided with a corrugation 114 which extends parallel to the corrugation 109. In the same way, the tongue 112 has a corrugation 115. On the side opposite the tongue 105, the covering carrier element 100 has a recess 117 for successively carrying a further lining carrier element (not shown), which is designed exactly like the lining carrier element 100.

In Figure 13, two lining support members 120, 121 are shown in perspective, which are constructed identically and partially abut each other. The construction and the function of the lining carrier elements 120, 121 will be explained with reference to FIG. 14 using the lining carrier element 120 as an example.

In FIG. 14, it can be seen that the pad carrier 120 has a mounting portion 122 in which three through holes 123, 124 and 126 are recessed. In the radial outward direction, the attachment portion 122 is bounded by a corrugation 125a, which is lowered. right to a radial runs. Parallel to the corrugation 125a, a further corrugation 126a is mounted, from which a rectangular section 125 extends radially outward. Radially outward from the rectangular portion 125 is a tongue 127. On the tongue

127 is formed a support surface which comes in the assembled state of the clutch disc to a corresponding support surface for abutment, which is formed on the lining support member 121. The rectangular section 125 becomes laterally of two corrugations

128 and 129 limited. From the corrugation 129 extends laterally to the right a wing 131 which is substantially complementary to a wing 132 which extends laterally from the corrugation 128 to the left. The wing 131 has a central window 133, which is formed substantially rectangular. Above and below the window 133, corrugations 134, 135 extend in the direction of a radial. Parallel to the corrugations 134 and 135, the wing 131 has a corrugation 136.

The wing 132 is provided with a window 138, which has substantially the shape of a rectangle. Above the window 138, the wing 132 has a substantially rectangular recess 139 which is open to the outside. In addition, in the wing 132, three corrugations 141 to 143 are formed, which extend in the direction of a radial. The corrugations 141 and 142, like the corrugations 134, 135, extend into the plane of the paper.

FIG. 15 shows two lining carrying elements 151, 152 in the assembled state, which are constructed identically. The pad carrying member 151 has a fixing portion 153 provided with three through holes 154, 155, 156. From the mounting portion 153 is a substantially rectangular portion 158, from the side two wings 159, 160 go out. The rectangular section 158 is bounded laterally by two corrugations 161 and 162, which extend in the direction of a radial. Parallel to the corrugations 161 and 162, a corrugation 163 extends centrally between the two corrugations 161 and 162. Over the entire width of the rectangular portion 158, a window 165 extends into the wings 159, 160 inside.

In FIG. 16, it can be seen that the lining-carrying element 152 has the same structure as the lining-carrying element 151. The lining-carrying element 152 has a fastening section 173, which is provided with three through-holes 174 to 176. From the attachment portion 173 extends in the radial direction upwardly a substantially rectangular portion 178. In turn, two wings 179, 180 extend laterally from the rectangular section 178. The rectangular section 178 is delimited laterally by two corrugations 183, 182 which extend in the direction of a radial. Parallel to and centered on the corrugations 181, 182, a corrugation 183 extends in the rectangular section 178. Across the entire width of the rectangular section 178 extends an elongate substantially rectangular window 185. From the left edge of the window 185, a tongue 186 extends , On the side facing the observer, the tongue 186 has a covering adhesive surface 188.

In Figure 17, two lining support elements 191, 192 are shown in the assembled state. The two lining support elements 191, 192 are of identical design and, like all embodiments shown in FIGS. 13 to 33, are prestressed in pairs in the axial direction against one another. The construction and the function of the lining support element 191 will be explained below with reference to the embodiment shown in FIG.

In FIG. 18, it can be seen that the lining-carrying element 191 has a fastening section 193 with three through-holes 194 to 196. The attachment portion 193 is separated from a substantially rectangular portion 201 by two corrugations 198, 199 that are perpendicular to a radial. Section 201 has a planar pad attachment surface 202 visible to the viewer. The pad attachment surface 202 is bounded laterally by corrugations 204, 205 which extend in the direction of a radial. From the section 201 go out two wings 207 and 208 laterally. The vane 207 has two corrugations 209, 210 which are parallel to the corrugations 204 and 205. Likewise, the wing 208 has two corrugations 211, 212 which are also parallel to the corrugations 204 and 205. Finally, the portion 201 has an elongated window 214 which extends perpendicular to a radial over the entire width of the portion 201 into the tongues 207 and 208, which are also referred to as wings. The left half 215 of the window 214 has a slightly greater height than the right half 216 of the window 214. In the left half 215, a tongue 217 is arranged, which extends from the left edge of the window 214 and is offset in the axial direction relative to the pad mounting surface 202 in the sheet plane.

In FIG. 17 it can be seen that a tongue 219 with a lining mounting surface 220 is formed on the lining carrier element 192 in the same way as in the lining carrier element 191, which faces the viewer. In the exemplary embodiment illustrated in FIG. 17, it is thus possible for one and the same clutch lining to be fastened to pad attachment surfaces 202 and 220 on different pad carrier elements 191 and 192.

In Figure 19, two lining support elements 221, 222 are shown in the assembled state. The construction and the function of the identically formed support elements 221 and 222 will be explained with reference to the embodiment shown in FIG.

In FIG. 20, it can be seen that the pad-carrying element 222 has a fastening section 223 with three through-holes 224 to 226. Of the mounting portion 223, a substantially rectangular portion 231 is separated by corrugations 227, 228 which are perpendicular to a radial. The substantially rectangular section 231 is bounded laterally by corrugations 232, 233. From the corrugation 233, a wing 236 extends circumferentially outward. From the corrugation 232 extends in the opposite direction, a wing 237. In addition, limit the corrugations 232, 233, which extend in the direction of a radial, a lining adhesive surface 234, which is shown cross hatched. The flights! 236, 237 have continuous corrugations 238, 239 which run parallel to the corrugations 232, 233. From the left wing 237 goes radially outward, so in the top 20, a tongue 240, which extends from outside to inside. On the side opposite the tongue 240, the wing 236 has a recess 241 which serves to pass a tongue 243 (see FIG. 19) with a covering adhesive surface 244 formed on the lining carrier element 221.

In Figure 21 two Belagtragelemente 251, 252 are shown in the assembled and axially mutually braced state. The construction and the function of the identically constructed covering carrier elements 251, 252 will be explained below with reference to the lining carrier element 251 shown in FIG.

The lining-carrying element 251 shown alone in FIG. 22 has a fastening section 253 with three through-holes 254 to 256. The attachment portion 253 is bounded by a circumferentially extending corrugation 261. Coaxially with the corrugation 261, the covering carrier element 251 has further corrugations 262, 263, which likewise run in the circumferential direction. The term circumferential direction refers to the axis of rotation of the clutch disc (1 in Figure 1). Within the corrugations 262, 263 are in the lining support member 251 two in Substantially rectangular windows 265, 266 formed. From the upper edge of the window 266, a substantially rectangular tongue 268 extends downwardly. The tongue 268 is formed curved in the plane of the drawing. For this purpose, the tongue 268 has two corrugations 271, 272, which run perpendicular to a radial.

In Figure 21 it can be seen that the pad carrying member 252 likewise has a tongue 274 which is provided with corrugations 275 and 276. The corrugations 275 and 276 define a pad attachment surface 278 that faces the viewer of FIG. 21. The pad attachment surface 278 extending from the tongue 274 of the pad carrier 252 is disposed in the window 265 of the pad carrier 251.

In Figure 23, two Belagtragelemente 281 and 282 are shown in the assembled and axially biased against each other state. The two lining support elements 281 and 282 are identical. The construction and the function of the lining carrier elements 281 and 282 will be explained below with reference to the lining carrier element 281 shown in perspective in FIG.

In Figure 24, it can be seen that the pad-carrying member 281 comprises a mounting portion 283 having three through-holes. The attachment portion 283 is separated from a substantially rectangular portion 284 by two corrugations 285 and 286 which extend in the circumferential direction. Coaxial with the corrugations 285 and 286, a corrugation 287 also extends in the circumferential direction. Within the corrugations 287 and 286, two substantially rectangular windows 288, 289 are recessed in the lining support element 281. From the upper edge of the window 289, a tongue 290 extends downwards. The tongue 290 is bent by a corrugation 291 in the axial direction relative to the portion 284 in the plane of the drawing.

In FIG. 23, it can be seen that, in the assembled state of the lining carrier elements 281, 282, a tongue 292 with a lining adhesive surface 293 facing the observer, which starts from the lining carrier element 282, is arranged in the window 288 of the lining carrier element 281.

FIG. 25 shows two lining carrying elements 301, 302 in the assembled state. The two in the axial direction against each other biased lining support members 301, 302nd are identical. In the following, the construction and the function of the lining carrier elements 301, 302 are explained on the basis of the lining carrier element 301 shown in FIG.

In Figure 26, it can be seen that the pad support member 301 comprises a mounting portion 303 having two through holes. The attachment portion 303 is separated from the remainder of the pad support member 301 by a slot 305 which is perpendicular to a radial. Laterally, the attachment portion 303 is bounded by corrugations 298, 299 which extend in the direction of a radial. Radially outside, that is above the slot 305, the pad carrier 301 has an elongated window 306 which extends parallel to the slot 305 perpendicular to a radial. From the left edge of the window 306 goes out a tongue 307.
