Fuwa rear Brake Chamber Double
1. Function
• Dual Braking Function:
• Service Brake : When compressed air enters the service chamber ("11" port), it pushes the diaphragm, activating the brake through the pushrod.
• Parking Brake : When the parking chamber ("12" port) is depressurized, the stored energy spring releases, pushing the diaphragm and engaging the brake.
• Emergency Brake Safety: In case of air supply failure, the parking brake automatically engages, ensuring vehicle immobilization.
• Load-Adaptive Braking: The dual-chamber design allows independent adjustment of service and parking brake forces, adapting to different loads and driving conditions.
2. Specifications
• Chamber Configuration:
• Service Chamber : For dynamic braking during vehicle operation.
• Parking Chamber : For static braking when parked or in emergency situations.
• Ports:
• "11" Port: Service brake air inlet.
• "12" Port: Parking brake air inlet/exhaust.
• Mounting: Typically bolted to the rear axle brake assembly, with flanges or brackets for secure attachment.
3. Material
• Chamber Body: High-strength aluminum alloy or cast iron for durability and pressure resistance.
• Diaphragm: Rubber or polymer-based flexible membrane to separate air chambers and transmit force.
• Spring: High-tensile steel spring for energy storage and parking brake actuation.
• Seals: Rubber or synthetic seals to prevent air leakage and ensure long-term reliability.
4. Key Parameters
• Working Pressure:
• Service Chamber: 8–10 bar (116–145 psi).
• Parking Chamber: 8–10 bar (116–145 psi) for release, 0 bar for engagement.
• Brake Force:
• Service Brake: Typically 11,000–15,000 N (2,473–3,372 lbf) at rated pressure.
• Parking Brake: 10,000–14,000 N (2,248–3,147 lbf) via spring force.
• Pushrod Stroke: 40–65 mm (1.57–2.56 in), depending on model.
• Temperature Range: -40°C to +80°C (-40°F to +176°F), ensuring operation in extreme climates.
• Cycle Life: ≥1,000,000 cycles (service brake), with spring fatigue resistance tested for long-term use.
• Weight: Approximately 8–12 kg (17.6–26.5 lbs), varying by size and configuration.
5. Additional Features
• Corrosion Resistance: Coated body and stainless-steel fasteners for extended lifespan in harsh environments.
• Modular Design: Allows easy replacement of individual components (e.g., diaphragm, spring) without full chamber replacement.
• Compliance: Meets international standards such as SAE J1402, ECE R13, and FMVSS 121 for brake system safety.
