Hydrodynamic Coupling with Brake Wheel
Integrated Transmission & Braking · Overload Protection · Heavy-Duty Precision Stopping

Hydrodynamic Coupling with Brake Wheel is an all‑in‑one power transmission device that merges fluid coupling flexibility with a robust mechanical brake. Unlike external brakes that add complexity, our design integrates the brake wheel directly into the coupling housing. This gives you two critical functions in one compact unit: smooth, shock‑absorbing power transmission and active, controllable braking. The result is ideal for heavy‑duty equipment that needs precise stopping, frequent start‑stop cycles, and enhanced operator safety — such as mining hoists, overhead cranes, and downhill conveyors.

✔ Why the Brake Wheel Design Stands Out

• Faster, more positive braking – The brake wheel offers a larger friction surface than a disc, providing stronger braking torque and better heat dissipation during repeated stops.

• Lower maintenance than dry shoe brakes – Oil splash from the fluid coupling keeps the brake wheel surface clean and reduces wear, extending lining life.

• Smooth starts even under full load – The fluid coupling eliminates shock, protecting belts, chains, and gearboxes while the brake wheel holds the load when stopped.

• No external brake caliper or linkage required – The compact, enclosed design saves space and simplifies installation.

• Ideal for regenerative loads – On downhill conveyors or lowering winches, the brake wheel provides controlled retarding without overheating.

• Wide temperature tolerance – Engineered with high‑temperature resistant seals and oil, it operates reliably from -20°C to +80°C.

⚙️ How the Brake Wheel Coupling Works

The unit contains a standard fluid coupling circuit (pump wheel + turbine) plus a brake wheel fixed to the output side. During normal operation, hydraulic fluid transmits torque smoothly, allowing the motor to start under no load and the load to accelerate gradually. When braking is needed, an external actuator (pneumatic or hydraulic caliper, or a band brake) compresses the brake wheel’s friction surface. Because the brake wheel is directly connected to the output shaft, stopping torque is applied instantly. Meanwhile, the fluid coupling continues to slip, absorbing residual kinetic energy and preventing sudden mechanical lock‑up. This two‑stage deceleration – fluid slip then mechanical hold – gives a much smoother stop than a conventional brake alone, reducing shock to the downstream machinery.

? Where the Brake Wheel Coupling Excels

This design is the preferred choice for equipment that requires both soft start and positive holding:

• Mine hoists & shaft winders – Smooth acceleration and precise stopping prevent rope slip and cage overshoot.

• Overhead travelling cranes – Allows micro‑speed positioning and emergency braking without damaging gearboxes.

• Downhill belt conveyors – Regenerative braking is managed smoothly, avoiding belt tear and motor overspeed.

• Marine winches & capstans – Corrosion‑resistant versions withstand salt spray and high humidity.

• Large elevators & vertical lifts – Provides fail‑safe braking and smooth starts for heavy payloads.
