Key Features:
- ISO/SAE Compliance: Components meet ISO 7638, SAE J1409, and ABS/EBS 4S/2M standards.
- Material Durability: Aluminum alloy, FKM/EPDM seals, and shielded cables ensure longevity in harsh environments.
- Critical Safety: Redundant pneumatic circuits, rapid pressure release (<0.3s), and EMI-resistant signal transmission.
This list includes core components for semi-trailer air brake systems compliant with EBS/ABS 4S/2M standards, covering pneumatic control, power supply, and signal transmission:
- ABS Combination Valve (4005000810): Real-time pressure regulation with gold-plated contacts for zero signal delay.
- 12m Power Cable (4491301200): Dual-layer EMI shielding, ISO 7638-compliant for stable power delivery.
- Hybrid Power Cable (4493792810): Integrates power and CAN signals, reducing wiring complexity (SAE J1939).
- 3m Sensor Cable (4497490300): 22AWG tinned copper ensures minimal signal loss over 3m.
- Handshake Connectors:
- Yellow (9522010010): Standard brake interface with EPDM seals (IP69K).
- Red (9522010020): Emergency brake redundancy with dual pneumatic circuits.
- Single Release Valve (9630060030): Rapid pressure exhaust (≤0.3s response), 45% lighter cast aluminum.
- Four-Port Relay Valve (9710020400): Auto-switching backup circuit, EPDM seals for 2M+ cycles.
- Quick Release Valve (9735000510): Instant pressure release with FKM seals for corrosion resistance.
Key Importance:
- Regulatory Compliance: ISO 1215/SAE J1409 certified for global compatibility.
- Material Impact:
- High Conductivity: Tin-plated copper reduces signal loss.
- Lightweighting: Aluminum/glass-fiber materials cut weight by 30-50%.
- Environmental Resistance: EPDM/FKM seals withstand -50℃~200℃ extremes.
Replacement Guidelines:
- Professional Installation: Pneumatic components require torque control (e.g., 35±5Nm for ABS valves).
- System Calibration: Post-replacement diagnostics via WABCO/Knorr-Bremse tools.
- OEM Parts: Non-genuine parts risk impedance mismatch or seal failure.
