High-Performance Brake Discs for Enhanced Vehicle Safety

Brake discs engineered specifically for Li Xiang (Li Auto) vehicles address the unique braking requirements of extended-range electric vehicles (EREVs) that combine electric motor regeneration with conventional friction braking. These rotors must accommodate the distinctive weight distribution and powertrain characteristics of models like Li Xiang ONE and Li Xiang L9, which typically weigh 2,500-2,800 kg due to battery systems while maintaining refined braking feel expected from premium vehicles. Engineering considerations focus on thermal management for the blended braking system where friction components may see reduced but more inconsistent use compared to conventional vehicles. Material selection typically utilizes high-carbon iron alloys with enhanced thermal conductivity and specific heat capacity to handle the heat generated during full friction braking events when regenerative braking is unavailable or insufficient. Rotor designs often incorporate internal vane configurations optimized for directional cooling airflow, with vane shapes and counts specifically calculated for Li Xiang's hub and knuckle assemblies. A documented case from fleet operators demonstrates how application-specific brake discs resolved premature thickness variation issues in Li Xiang vehicles used for ride-sharing services with high urban stop frequency. Surface treatment options include geometric coating protection for corrosion resistance on non-friction surfaces—particularly important for electric vehicles that generate less braking heat to burn off surface oxidation. Noise vibration harshness (NVH) characteristics receive particular attention through chamfered cooling vanes and balanced mass distribution to prevent low-frequency brake moan common in heavy vehicles. Our manufacturing process includes specialized runout control during machining to meet Li Xiang's precise compatibility requirements with electronic parking brake systems. Performance validation involves testing on inertia dynamometers simulating the vehicle's specific weight distribution and regeneration patterns. For application-specific brake discs compatible with Li Xiang vehicle models, we provide comprehensive technical documentation including installation procedures, bedding recommendations, and performance characteristics through our EV components division.
