Electro-hydraulic brake module

摘要

An electro-hydraulic brake module (M) for a wind energy plant (W) has at least one spring accumulator brake cylinder (Z) with an electronic control unit (C) to control the hydraulic pressure acting on the cylinder via a connected valve assembly. The brake module implements proportional braking control if the power supply fails by controlling outlet to a tank (T) using a proportional, solenoid (15) activated, pressure limiting control valve (V1) and supply using a switching valve (V2) activated by a black-white magnet (17) in a parallel line (6) to the brake cylinder.
