A multiple disk clutch device for arrangement in a drivetrain of a motor vehicle between a drive unit and a transmission, includes at least an inner and an outer disk clutch arrangement that are radially staggered and associated with a transmission input shaft of the transmission. Each of the plural clutch disk arrangements includes a set of disks, the set of disks have an outer disk associated with an outer disk carrier and an inner disk associated with an inner disk carrier. The outer disks are operable to mutually engage the inner disks in a driving arrangement. Each of the plural disk sets includes at least one disk having a lining and at least one disk being unlined where one of the inner and outer disks of the inner and the outer disk clutch arrangements of the plural disk clutch arrangements is the lined disk.

The invention claimed is: 1. A double clutch device for arrangement in a drivetrain of a motor vehicle between a drive unit and a transmission having a plurality of gears including odd gears and even gears, the clutch device comprising: two coaxial input shafts of the transmission, wherein one of said coaxial input shafts is associated with only the odd gears of the transmission and the other of said coaxial input shafts being associated with only the even gears of the transmission; an inner disk clutch arrangement and an outer disk clutch arrangement, the disk clutch arrangements being radially staggered and each being associated with a respective one said coaxial input shafts, each of the disk clutch arrangements comprising a set of disks, each said set of disks comprising outer disks associated with a respective outer disk carrier and inner disks associated with a respective inner disk carrier, the outer disks of each set operable to mutually engage the inner disks, one of the inner disks and outer disks of both disk clutch arrangements having linings, the other of the inner and outer disks of both disk clutch arrangements having no linings. 2. The double clutch device of claim 1, wherein the lined disks each comprise a lining-carrying element and a lining on both sides of the lining carrying element. 3. The double clutch device of claim 1, wherein the inner disks have linings. 4. The double clutch device of claim 1 wherein the unlined disks disposed in the inner and the outer disk clutch arrangements have a uniform axial thickness and are made from the same material. 5. The double clutch device of claim 2, wherein the lining-carrying elements have a uniform axial thickness and are made from the same material. 6. The double clutch device of claim 2 wherein the linings have a uniform axial thickness and are made from the same material. 7. The double clutch device of claim 1, wherein the lined disks each have a lining slot. 8. The double clutch device of claim 1, wherein the set of disks of the outer disk clutch arrangement has an inner diameter greater than the outer diameter of the set of disks of the inner disk clutch arrangement. 9. The double clutch device of claim 1 wherein the disks associated with the drive unit have an inertia greater as a whole than the disks associated with the transmission input shafts. 10. The double clutch device of claim 9, wherein the outer disks of both sets of disks are associated with the drive unit and the inner disks of both sets of disks are associated with the transmission input shafts. 11. A method of making a disk arrangement for a double clutch device, wherein the disk arrangement comprises at least one of first unlined disks associated with a first, radial outer disk clutch arrangement, and second unlined disks associated with a second, radial inner disk clutch arrangement; first lining-carrying elements associated with a first, radial outer disk clutch arrangement, and second lining-carrying elements associated with a second, radial inner disk clutch arrangement; and a plurality of first linings associated with a first, radial outer disk clutch arrangement, and a plurality of second linings associated with a second, radial outer disk clutch arrangement; the method comprising the step of: cutting from a common material piece a first material piece portion to comprise a first disk and a second material piece portion to comprise a second disk, wherein the first material piece portion to comprise the first disk surrounds the second material piece portion to comprise the second disk in the common material piece on the radial outside with respect to a reference point located inside the plural material piece portions, wherein the first and second disks comprise one of the first and second unlined disks or the first and second lining carrying elements. 12. The method making a disk arrangement of claim 11 further comprising the step of: associating the first disks with the first, radial outer disk clutch arrangement and the second disks with the second, radial inner disk clutch arrangement. 13. The method of claim 11 wherein said disk arrangement comprises first and second unlined disks and first and second lining carrying elements, wherein the first and second unlined disks are made by said step of cutting and the first and second lining carrying elements are made by said step of cutting. 14. A double clutch for arrangement in the drive train of a motor vehicle between a drive unit and a transmission having a plurality of gears including odd gears and even gears, said arrangement comprising: an outer input shaft of the transmission and an inner input shaft of the transmission which extends coaxially through said outer input shaft, wherein one of said input shafts is associated with only the odd gears of the transmission and the other of said input shafts being associated with only the even gears of the transmission; an outer disk clutch arrangement comprising a plurality of outer disks which are rotationally fixed with respect to an outer disk carrier which is rotationally fixed with respect to said drive unit, and a plurality of inner disks which can be brought into driving engagement with said outer disks and which are rotationally fixed with respect to an inner disk carrier which is rotationally fixed with respect to said outer input shaft; and an inner disk clutch arrangement located radially inside of said outer disk clutch arrangement and comprising a plurality of outer disks which are rotationally fixed with respect to an outer disk carrier which is rotationally fixed with respect to said drive unit, and a plurality of inner disks which can be brought into driving engagement with said outer disks and which are rotationally fixed with respect to an inner disk carrier which is rotationally fixed with respect to said inner input shaft; wherein one of said inner disks and said outer disks of both of said disk clutch arrangements have linings, the other of said inner and said outer disks having no linings. 15. A double clutch as in claim 14 wherein said inner disks have linings. 16. A double clutch as in claim 14 wherein said disks having linings each comprise a lining carrying element having a lining on at least one side. 17. A double clutch as in claim 16 wherein said lining carrying elements are all made of the same material and have a uniform thickness. 18. A double clutch as in claim 14 wherein the disks having no linings are all made of the same material and have a uniform thickness.
