Braking structure of aerogenerator driftage calliper

The utility model discloses a braking structure of aerogenerator driftage calliper relates to the aerogenerator field, a serial communication port, including calliper seat, piston and braking piece, the calliper seat is equipped with at least one through -hole, the piston wear to establish with in the through -hole, the piston with form the face contact during braking of braking piece. The utility model discloses beneficial effect: be equipped with at least one through -hole on the calliper seat, the piston wear to establish with in the through -hole, the piston forms the face contact with braking piece when braking, adopts the form of face contact, and in the braking, braking piece atress is even, local atress situation can not appear and damages the braking piece, has promoted braking effect greatly, has avoided the braking piece frequently to change, practices thrift the maintenance cost.
