Abstract
A wind energy plant with a hydraulically actuated rotor brake for a drive train, which has at least one hydraulically actuated brake cylinder, the braking moment of which gets stronger when the hydraulic pressure increases, wherein a volume of hydraulic fluid is tensioned by a pressure reducing valve in the brake cylinder and in the pressure line thereof when the brake is actuated, wherein an accumulator with hydraulic fluid is provided, which is connected to the pressure line.
Claims13
A wind energy plant with a hydraulically actuated rotor brake for a drive train, which has at least one hydraulically actuated brake cylinder (38), the braking moment of which gets stronger when the hydraulic pressure increases, wherein a volume of hydraulic fluid is tensioned by a pressure reducing valve (20) in the brake cylinder (38) and in the pressure line (24, 36) thereof when the brake is actuated, characterised in that an accumulator (28) with hydraulic fluid is provided, which is connected to the pressure line (24, 36).
