Fail-Safe Shaft Thruster Brake

Work cycle process:

     Release brake (operating state): The thruster is powered on, the motor drives the centrifugal pump to establish oil pressure, the piston rod extends, and the main spring is compressed by the lever mechanism, causing the brake pads on both sides to detach from the brake wheel, and the mechanism can operate.

     Brake (braking state): When power is cut off or pressure is lost, the motor stops and the oil pressure disappears. The main spring releases its elastic force to push the lever, forcing the brake pad to tightly press against the brake wheel, generating friction torque to achieve deceleration or parking braking. ‌‌

Key components:
     Electric hydraulic thruster: converts electrical energy into hydraulic thrust and is responsible for providing "release" power.
     Brake frame and lever system: amplifies thrust and transmits motion to achieve the opening and closing of tiles.
     Main spring: Provides normally closed braking force to ensure fail safe power-off.
Brake pad: asbestos free pad, directly rubs against the brake wheel to generate braking torque. ‌‌
