Patent ID: 8550769

Claim:
A wind turbine comprising a tower and a nacelle which is rotatably mounted on the tower and whose alignment is adjustable by means of a yaw system ( 2 ), wherein the yaw system has at least one adjusting drive ( 18 ), a rotatable yaw bearing ( 10 , 12 ), at least one brake disk ( 16 ) and at least two brake units (B 1 to B 14 ) which can exert a braking torque on the brake disk, characterised in that at least one of the brake units (B 1 , B 14 ) has a first brake pad ( 17 ) with a first coefficient of friction, and at least one of the brake units (B 2 to B 13 ) has a second brake pad ( 17 ) with a second coefficient of friction, wherein the first and the second coefficient of friction are different from each other.
