Abstract

A multi-disk shifting element of a motor vehicle transmission, which includes a plurality of outer disks ( 2 ) and a plurality of lining disks ( 1 ) which, when viewed axially, are arranged in alternation one after another. The outer disks include a number of flat outer disks (AL 1 ) and a number of corrugated outer disks (AL 2 , AL 3 ).

First claim

The invention claimed is:

1. A multi-disk shifting element of a motor vehicle transmission, the multi-disk shifting element comprising a plurality of outer disks ( 2 ) and a plurality of lining disks ( 1 ), the outer disks and the lining disks are alternately arranged along an axis, the outer disks ( 2 ) comprise a plurality of flat outer disks (AL 1 ) and a plurality of corrugated outer disks (AL 2 ), the plurality of corrugated outer disks have corrugations, and the plurality of corrugated outer disks are arranged with respect to each other such that the corrugations thereof are aligned in a common direction, and the flat outer disks (AL 1 ) and the corrugated outer disks (AL 2 ) are alternately arranged along the axis, in series, and between one flat outer disk (AL 1 ) and one corrugated outer disk (AL 2 ) adjacent thereto, exactly one lining disk ( 1 ) is arranged.

2. The multi-disk shifting element according to claim 1 , wherein a first flat outer disk is arranged at one axial end of the multi-disk shifting element and a second flat outer disk is arranged at an opposite axial end of the multi-disk shifting element, and the plurality of flat outer disks are axially located between the first and the second flat outer disk.

3. A multi-disk shifting element of a motor vehicle transmission, the multi-disk shifting element comprising a plurality of outer disks ( 2 ) and a plurality of lining disks ( 1 ), the outer disks and the lining disks are alternately arranged along an axis, the outer disks ( 2 ) comprise a plurality of flat outer disks (AL 1 ) and a plurality of corrugated outer disks (AL 2 ), the plurality of corrugated outer disks have corrugations, and the plurality of corrugated outer disks are arranged with respect to each other such that the corrugations thereof are aligned in a common direction, and the flat outer disks (AL 1 ) and the corrugated outer disks (AL 2 ) are arranged along the axis such that between two adjacent flat outer disks (AL 1 ) in each case only one lining disk ( 1 ) is arranged, and between two adjacent corrugated outer disks (AL 2 ) in each case only one lining disk ( 1 ) is arranged.

4. The multi-disk shifting element according to claim 3 , wherein the plurality of flat outer disks are arranged on one axial side of the multi-disk shifting element with respect to the plurality of corrugated outer disks and the plurality of corrugated outer disks are arranged on an opposite axial side of the multi-disk shifting element with respect to the plurality of flat outer disks.

5. A multi-disk shifting element of a motor vehicle transmission, the multi-disk shifting element comprising a plurality of outer disks ( 2 ) and a plurality of lining disks ( 1 ), the outer disks and the lining disks are alternately arranged along an axis, the outer disks ( 2 ) comprise a plurality of flat outer disks (AL 1 ) and a plurality of corrugated outer disks (AL 2 , AL 3 ), the corrugated outer disks comprise corrugated outer disks (AL 3 ) having corrugations that are arranged in a direction opposite to a direction of corrugations of other corrugated outer disks (AL 2 ), and when viewed along the axis, each corrugated outer disk (AL 2 , AL 3 ) is respectively arranged with the corrugations thereof being oppositely directed to a next corrugated outer disk, and the flat outer disks (AL 1 ) and the corrugated outer disks (AL 2 , AL 3 ) are alternately arranged along the axis one behind the other, such that between a flat outer disk (AL 1 ) and a corrugated outer disk (AL 2 , AL 3 ) adjacent thereto, only one lining disk ( 1 ) is arranged.

6. A multi-disk shifting element of a motor vehicle transmission, the multi-disk shifting element comprising a plurality of outer disks ( 2 ) and a plurality of lining disks ( 1 ), the outer disks and the lining disks are alternately arranged along an axis, the outer disks ( 2 ) comprise a plurality of flat outer disks (AL 1 ) and a plurality of corrugated outer disks (AL 2 , AL 3 ), the corrugated outer disks comprise corrugated outer disks (AL 3 ) having corrugations that are arranged in a direction opposite to a direction of corrugations of other corrugated outer disks (AL 2 ), and when viewed along the axis, the corrugated outer disks (AL 2 , AL 3 ) are respectively arranged in pairs with the corrugations thereof being oppositely directed, and the corrugated outer disks (AL 2 , AL 3 ) are arranged, when viewed along the axis, beside the flat outer disks (AL 1 ), such that between two adjacent flat outer disks (AL 1 ) is arranged in each case one lining disk ( 1 ), and between two adjacent corrugated outer disks (AL 2 , AL 3 ) is arranged each in each case exactly one lining disk ( 1 ), and
the plurality of flat outer disks are arranged on one axial side of the multi-disk shifting element with respect to the plurality of corrugated outer disks and the plurality of corrugated outer disks are arranged on an opposite axial side of the multi-disk shifting element with respect to the plurality of flat outer disks.
