Friction lining
View Patent ↗The invention relates to a method for producing a friction lining. Said friction lining is wound in three layers with different winding ratios.
1. A method for producing a friction lining for clutches or brakes comprising:
at least one winding, the winding being wound from a plurality of plies of at least one impregnated yarn,
wherein a first predetermined number of plies with a first predetermined winding ratio, which form a first layer, a second predetermined number of plies with a second predetermined winding ratio, which form a second layer, and a third predetermined number of plies with a third predetermined winding ratio, which form a third layer, are wound, at least two of three layers having a different predetermined number of plies, wherein the first and the second and the third predetermined number of plies are between 3 and 7.
2. The method of claim 1 , wherein the first and the third predetermined number of plies are equal.
3. The method of claim 1 , wherein the second winding ratio is unequal to the first and the third winding ratio.
4. The method of claims 1 , wherein the second winding ratio is lower than the first and the third winding ratio.
5. The method of claim 1 , wherein the first and the third winding ratio are equal.
6. The method of claim 1 , wherein the first and the third winding ratio amount to between 1:4.5 and 1:5.0, and the second winding ratio amounts to between 1:1.0 and 1:1.3.
7. The method of claim 1 , wherein the first and/or or the third layer are/is wound from a friction yarn, and remaining layers are wound from a reinforcing yarn, the friction yarn having better frictional and/or wearing properties than the reinforcing yarn.
8. The method of claim 2 , wherein the first and the third predetermined number of plies are 4, and the second predetermined number of plies is 6.
9. The method of claim 1 , wherein the first and the third winding ratio amount to 1:4.72, and the second winding ratio amounts to 1:1.12.
10. A friction lining for clutches or brakes, comprising:
at least one winding, the winding consisting of a plurality of plies of at least one impregnated yarn,
wherein a first predetermined number of plies which arc wound with a first predetermined winding ratio form a first layer, a second predetermined number of plies which are wound with a second predetermined winding ratio form a second layer, and a third predetermined number of plies which are wound with a third predetermined winding ratio form a third layer, at least two of three layers having a different predetermined number of plies, wherein the first and the second and the third predetermined number of plies are between 3 and 7.
