Abstract
The invention relates to a brake system for a wind turbine having a machine house rotatably mounted in horizontal plane on a tower, at least one stop brake (60) for locking the machine house and an electrical azimuth drive (40), wherein the stop brake (60) is connected to the azimuth drive (40) via means (50) for transferring moments and/or forces and/or movements in such a way that it can be actuated by means of a torsional moment generated by the azimuth drive (40) in order to yaw the machine house and/or a force and/or movement generated for this reason.
Claims15
Brake system for a wind turbine with a machine house supported on a tower in a manner of being rotatable in horizontal plane, wherein the brake system comprises at least one stop brake (60) for locking and/or for braking the machine house and an electric azimuth drive (40), characterized in that
- the stop brake (60) is connected to the azimuth drive (40) via means (50) for transferring moments and/or forces and/or movements in such a way that
- it can be actuated by means of a torsional moment generated by the azimuth drive (40) for yawing of the machine house and/or by means of a force and or movement generated for this purpose.
Azimuth drive (40) according to claim 11, wherein the ring gear (46H) of the planetary gear set (46) can only be rotated by a predetermined maximal angle relative to the housing (44) in positive or negative rotation direction.
Azimuth drive (40) according to claim 11, wherein the ring gear (46H) of the planetary gear set (46) is damped relative to the housing (44) by means of a hydraulic clutch (45).
Stop brake (60) for a machine house with at least one friction lining (66), a pressing stamp (30, 70, 78) and a restoring spring (74), wherein the stop brake (60) causes a locking and/or braking of the nacelle by means of the restoring force of the restoring spring (74) in installed state, and wherein a lever (50) directly or indirectly connected or connectable to the pressing stamp (30, 70, 78) reduces the restoring force of the restoring spring (74) during operation and thereby cancels the locking of the machine house, wherein the stop brake (60) is connected to the azimuth drive (40) by means (50) for transmitting moments and/or forces and/or movements, so that it is able to be operated by means of a torsional moment generated by the azimuth drive (40) for yawing of the machine house and/or a force and/or movement generated for this purpose.
Stop brake (60) according to claim 14, wherein the restoring effect of the restoring spring (74) is damped by means of a damper (80).
