Abstract

A multilayered friction lining, including friction member ( 4, 4 a ) that forms a friction surface; and reinforcement member ( 3, 3 a ). Reinforcement member ( 3, 3 a ) is wound of reinforcement yarn and friction member ( 4, 4 a ) is wound of friction yarn. The friction yarn features friction and/or anti-wear properties better than of the reinforcement yarn, the friction member ( 4, 4 a ) is wound with a friction coil-winding ratio and the reinforcement member ( 3, 3 a ) is wound with a reinforcement coil-winding ratio, and the friction coil-winding ratio is greater than or equal to said reinforcement coil-winding ratio.

Claims (28)

1. A multilayered friction lining, comprising:

friction member ( 4 , 4 a ) that forms a friction surface; and,

reinforcement member ( 3 , 3 a ), wherein said reinforcement member ( 3 , 3 a ) is wound of glass fiber reinforcement yarn and said friction member ( 4 , 4 a ) is wound of aramid friction yarn and glass fiber reinforcement yarn and said friction yarn features friction or anti-wear properties better than of said reinforcement yarn, wherein said friction member ( 4 , 4 a ) is wound with a friction coil-winding ratio and said reinforcement member ( 3 , 3 a ) is wound with a reinforcement coil-winding ratio, wherein said friction coil-winding ratio is greater than said reinforcement coil-winding ratio.

2. The multilayered friction lining according to claim 1 further comprising a double-layered clutch lining.

3. The friction lining according to claim 1 , wherein said reinforcement member ( 3 , 3 a ) features a bursting speed higher than that of said friction member ( 4 , 4 a ).

4. The friction lining according to claim 1 , wherein the friction coil-winding ratio and the reinforcement coil-winding ratio lie within a range between 0.2 and 6.0, respectively.

5. The friction lining according to claim 1 , wherein the friction coil-winding ratio lies between 4.5 and 5.0.

6. The friction lining according to claim 1 , wherein the friction coil-winding ratio lies between 2.2 and 3.0.

7. The friction lining according to claim 1 , wherein the friction coil-winding ratio lies between 2.2 and 6.0.

8. The friction lining according to claim 1 , wherein the reinforcement coil-winding ratio lies between 1.0 and 1.5.

9. The friction lining according to claim 1 , wherein the reinforcement coil-winding ratio lies between 2.2 and 3.0.

10. The friction lining according to claim 1 , wherein the reinforcement coil-winding ratio lies between 0.2 and 5.2.

11. The friction lining according to claim 1 , wherein the friction member ( 4 , 4 a ) and the reinforcement member ( 3 , 3 a ) are essentially ring-shaped in form and are disposed directly above one another by forming a parting plane and as such form a composite, wherein said friction member ( 4 , 4 a ) and said reinforcement member ( 3 , 3 a ) blend into one another in the parting plane area.

12. The friction lining according to claim 1 , wherein the friction member ( 4 , 4 a ) includes coil ( 2 ), the reinforcement member ( 3 , 3 a ) includes coil ( 1 ), the reinforcement yarn includes end ( 1 a ), and the friction yard includes beginning ( 2 a ) and wherein the coil ( 2 ) is wound on the coil ( 1 ), end ( 1 a ) is wound from said coil ( 1 ), and beginning ( 2 a ) is disposed essentially within the parting plane.

13. A method for producing a multilayered friction lining, comprising:

winding reinforcement member ( 3 , 3 a ) out of glass fiber reinforcement yarn;

winding friction member ( 4 , 4 a ) out of aramid friction yarn and glass fiber reinforcement yarn; and,

forming a friction surface on the friction member, wherein said friction yarn features friction and/or anti-wear properties better than those of said reinforcement yarn, wherein said friction member ( 4 , 4 a ) is wound with a friction coil-winding ratio and said reinforcement member ( 3 , 3 a ) is wound with a reinforcement coil-winding ratio, and wherein said friction coil-winding ratio is greater than said reinforcement coil-winding ratio.

14. The method of claim 13 wherein the multilayered friction lining further comprises a double-layered clutch lining.

15. The friction lining according to claim 5 , wherein the friction coil-winding ratio is 4.72.

16. The friction lining according to claim 6 , wherein the friction coil-winding ratio is 2.6.

17. The friction lining according to claim 7 , wherein the friction coil-winding ratio is 4.7.

18. The friction lining according to claim 8 , wherein the friction coil-winding ratio is 1.12.

19. The friction lining according to claim 9 , wherein the friction coil-winding ratio is 2.6.

20. The friction lining according to claim 10 , wherein the friction coil-winding ratio is 4.7.

21. A multilayered friction lining, comprising:

friction member ( 4 , 4 a ) that forms a friction surface; and,

reinforcement member ( 3 , 3 a ), wherein said reinforcement member ( 3 , 3 a ) is wound of reinforcement yarn including a first material and said friction member ( 4 , 4 a ) is wound of reinforcement yarn including the first material and friction yarn including a second material, different from the first material and said friction yarn features friction or anti-wear properties better than of said reinforcement yarn, wherein said friction member ( 4 , 4 a ) is wound with a friction coil-winding ratio and said reinforcement member ( 3 , 3 a ) is wound with a reinforcement coil-winding ratio, wherein said friction coil-winding ratio is greater than said reinforcement coil-winding ratio.
