Abstract

The present invention relates to a disk clutch comprising a first disk set (32) which is connected rotationally fixed to a first disk carrier (18) and a second disk set (42) which is connected rotationally fixed to a second disk carrier (24), wherein the disks (34 through 40, 46 through 52) of the two disk sets (32, 42) may be brought into frictional engagement with one another via friction surfaces (54, 56), wherein recesses and/or grooves are provided in at least one or more friction surfaces (54, 56) of the disks (34 through 40; 46 through 52) of the first and/or second disk sets (32; 42). A first type of recesses and/or grooves (68) is thereby provided, which is generated by a material shaping and/or a material casting and/or a non-material removing first manufacturing method, and a second type of recesses and/or grooves (70) is provided, which is generated by a material removing second manufacturing method. In addition, the present invention relates to a disk (66) for such a disk clutch and a method for producing such a disk clutch (2) and such a disk (60).

First claim

The invention claimed is:

1. A disk clutch ( 2 ), comprising a first disk set ( 32 ) which is connected rotationally fixed to a first disk carrier ( 18 ) and a second disk set ( 42 ) which is connected rotationally fixed to a second disk carrier ( 24 ), wherein disks ( 34 through 40 , 46 through 52 ) of the two disk sets ( 32 , 42 ) are configured to be brought into frictional engagement with one another via friction surfaces ( 54 , 56 ), wherein recesses and/or grooves are provided in at least one or more friction surfaces ( 54 , 56 ) of the disks ( 34 through 40 ; 46 through 52 ) of the first and/or second disk sets ( 32 ; 42 ), wherein a first type of recesses and/or grooves ( 68 ) is provided, which is generated by a material shaping and/or a material casting and/or a non-material removing first manufacturing method, and a second type of recesses and/or grooves ( 70 ) is provided, which is generated by a material removing second manufacturing method, wherein the at least one friction surface ( 54 , 56 ) or the multiple friction surfaces ( 54 , 56 ) is/are formed by a friction lining ( 60 , 62 ) fixed on a friction lining carrier ( 58 ), and wherein the friction lining ( 60 , 62 ) is glued on the friction lining carrier ( 58 ), or is fixed on the friction lining carrier ( 58 ) in segments, while generating an intermediate third type of recesses and/or grooves ( 72 ).

2. The disk clutch ( 2 ) according to claim 1 , wherein the first type of recesses and/or grooves ( 68 ) is generated by stamping and/or the second type of recesses and/or grooves ( 70 ) is generated by a mechanical manufacturing method.

3. The disk clutch ( 2 ) according to claim 2 , wherein the mechanical manufacturing method is milling.

4. The disk clutch ( 2 ) according to claim 1 , wherein the first type of recesses and/or grooves ( 68 ) have a lesser depth than the second type of recesses and/or grooves ( 70 ).

5. The disk clutch ( 2 ) according to claim 1 , wherein the disks ( 34 through 40 ) of the first disk set ( 32 ) are provided on both sides with the friction surfaces ( 54 , 56 ) with the recesses and/or grooves ( 68 , 70 ), whereas the disks ( 44 , through 52 ) of the second disk set ( 42 ) have no friction surfaces ( 54 , 56 ) provided with recesses and/or grooves.

6. The disk clutch ( 2 ) according to claim 1 , wherein at least one of the disks ( 34 through 40 , 44 through 52 ) has both the first type of recesses and/or grooves ( 68 ) as well as the second type of recesses and/or grooves ( 70 ).

7. The disk clutch ( 2 ) according to claim 6 , wherein both the first type of recesses and/or grooves ( 68 ) as well as the second type of recesses and/or grooves ( 70 ) are provided in one or both friction surfaces ( 54 ; 56 ) of this at least one disk ( 34 through 40 , 44 through 52 ).

8. A method for producing the disk clutch ( 2 ) according to claim 1 , comprising the method steps:
providing the disks ( 34 through 40 , 44 through 52 ) of the first disk set ( 32 ) connectable to the first disk carrier ( 18 ) and of the second disk set ( 42 ) connectable to the second disk carrier ( 24 ),
generating the first type of recesses and/or grooves ( 68 ) by the material shaping and/or the material casting and/or the non-material removing first manufacturing method in the friction surfaces ( 54 ; 56 ) of at least one of the disks ( 34 through 40 , 44 through 52 ),
generating the second type of recesses and/or grooves ( 70 ) by the material removing second manufacturing method in the friction surfaces ( 54 ; 56 ) of the at least one disk ( 34 through 40 , 46 through 52 ), and/or in the friction surfaces ( 54 ; 56 ) of at least one other disk ( 34 through 40 , 44 through 52 ), and
compiling a disk set ( 30 ) from the disks, including the disks ( 34 through 40 ; 44 through 52 ) having the grooves and/or recesses.

9. The disk clutch ( 2 ) according to claim 1 , wherein the disk clutch ( 2 ) is a hydraulically actuatable disk clutch ( 2 ).

10. The method for producing a disk clutch ( 2 ) according to claim 8 , wherein the disks ( 34 through 40 ) of the first disk set ( 32 ) are connected to a first disk carrier ( 18 ) in such a way, and the disks ( 44 through 52 ) of the second disk set ( 42 ) are connected to a second disk carrier ( 24 ) in such a way that their friction surfaces ( 54 , 56 ) may be brought into frictional engagement with one another.

11. The method for producing the disk clutch ( 2 ) according to claim 10 , wherein the providing of the disks ( 34 through 40 , 44 through 52 ) of the second disk set ( 42 ) comprises providing a friction lining carrier ( 58 ) and fixing of a friction lining ( 60 , 62 ) on the friction lining carrier ( 58 ) to form the at least one friction surface ( 54 ; 56 ).
