Abstract

A clutch disk (10) for a motor vehicle includes at least two axially opposed friction linings (18), a lining spring (16) and a drive carrier disk (14) with a spring window (24), wherein the lining spring (16) has at least one fastening portion (16a), a supporting portion (16b) and a plurality of spring segments (16c) arranged adjacent to one another in circumferential direction, and the spring segments (16c) are arranged radially outside at the supporting portion (16b) of the lining spring (16), and the fastening portion (16a) is arranged radially inside at the supporting portion (16b).

First claim

The invention claimed is:

1. A clutch disk ( 10 ) for a motor vehicle comprising: at least two axially opposed friction linings ( 18 ); at least one lining spring ( 16 ); and a drive carrier disk ( 14 ) comprising a spring window ( 24 ); wherein the at least one lining spring ( 16 ) has at least two fastening portions ( 16 a ), a supporting portion ( 16 b ) extending between the two fastening portions ( 16 a ) so as to run in a circumferential direction and a plurality of spring segments ( 16 c ) arranged adjacent to one another in the circumferential direction; the spring segments ( 16 c ) are arranged radially outside at the supporting portion ( 16 b ) of the lining spring ( 16 ), and the at least two fastening portions ( 16 a ) are arranged radially inside at the supporting portion ( 16 b ) and the two fastening portions are opposite one another in the circumferential direction at the spring window ( 24 ) and the at least two fastening portions ( 16 a ) circumferentially align with the spring window ( 24 ).

2. The clutch disk ( 10 ) according to claim 1 , wherein the supporting portion ( 16 b ) is arranged radially outwardly at the spring window ( 24 ).

3. The clutch disk ( 10 ) according to claim 1 , wherein the at least two fastening portions ( 16 a ) have at least two fastening openings ( 22 ) for receiving a fastening element ( 20 ).

4. The clutch disk ( 10 ) according to claim 3 , wherein the spring window ( 24 ) of the drive carrier disk ( 14 ) is bounded radially outwardly by a web ( 26 ), and wherein the supporting portion ( 16 b ) of the lining spring ( 16 ) covers the web ( 26 ) at least partially in radial direction.

5. The clutch disk ( 10 ) according to claim 4 , wherein the supporting portion ( 16 b ) overlaps the web ( 26 ) by at least fifty percent of the web, by two thirds of the web, or completely overlaps the web.

6. The clutch disk ( 10 ) according to claim 3 , wherein each of the at least two fastening portions have four fastening openings.

7. The clutch disc according to claim 1 , wherein the two fastening portions ( 16 a ) are located at the lining spring ( 16 ) so as to be adjacent on the circumference side to the spring window 24 .
