Abstract

A method for manufacturing a friction lamella by way of the following steps: a steel sheet is supplied, which is provided with macrostructuring on at least one face, a friction lamella blank is separated out from the steel sheet and further processed into an annular lamella body.

Claims

exact text as granted — not AI-modified
1 . A method for manufacturing a friction lamella comprising the following steps:
 a steel sheet is supplied, which is provided with macrostructuring on at least one face,   a friction lamella blank is separated out from the steel sheet and further processed into an annular lamella body.   
     
     
         2 . The method according to  claim 1 , characterized in that the friction lamella blank is annealed. 
     
     
         3 . The method according to  claim 1 , characterized in that the macrostructuring is rolled onto both faces of the steel sheet. 
     
     
         4 . The method according to  claim 3 , characterized in that the macrostructuring rolled onto one face is offset from the macrostructuring on the other face. 
     
     
         5 . The method according to  claim 1 , characterized in that the macrostructuring is a honeycomb pattern. 
     
     
         6 . The method according to  claim 1 , characterized in that the macrostructuring has a structure depth in the range of 0.05 to 0.9 mm. 
     
     
         7 . The method according to  claim 1 , characterized in that a structural element has a width in the range of 0.1 to 4 mm. 
     
     
         8 . The method according to  claim 1 , in that the lamella body is provided with at least one clearance. 
     
     
         9 . The method according to  claim 8 , characterized in that that the lamella body is provided with from 1 to 40 clearances. 
     
     
         10 . The method according to  claim 8 , characterized in that the clearance is a slit. 
     
     
         11 . The method according to  claim 10 , characterized in that the slit starts and ends at a distance from a circumferential edge of the friction lamella. 
     
     
         12 . The method according to  claim 10 , characterized in that the slit starts at a circumferential edge of the friction lamella and ends at a distance from a circumferential edge of the friction lamella. 
     
     
         13 . The method according to  claim 10 , characterized in that the slit extends from one circumferential edge of the friction lamella to the other circumferential edge of the friction lamella. 
     
     
         14 . The method according to  claim 10 , characterized in that the slit has a width in the range of 0.1 to 5 mm. 
     
     
         15 . The method according to  claim 10 , characterized in that the slit is at an angle of 0 to 70° to a radius of the friction lamella. 
     
     
         16 . The method according to  claim 10 , characterized in that the slit extends straight, curved or in a wave. 
     
     
         17 . The method according to  claim 8 , characterized in that the clearance is located at least in part in a region of the lamella body at a distance from a circumferential edge corresponding to more than 10% of the width of the lamella body. 
     
     
         18 . The method according to  claim 1 , characterized in that the lamella body forms a flat, planar disc. 
     
     
         19 . The method according to  claim 1 , characterized in that the lamella body is composed of a plurality of segments. 
     
     
         20 . The method according to  claim 1 , characterized in that microstructuring is superposed on the macrostructuring. 
     
     
         21 . The method according to  claim 20 , characterized in that the microstructuring is introduced by a grinding process.
