Dongfeng KC Rear intake duct bracket 1109012-K26B0

Constructed from high-quality Q235 carbon steel with a thickness of 5mm, the bracket features a reinforced triangular rib structure on the stress-bearing surface. This design enhances the bracket’s load-bearing capacity to a maximum of 80kg (static load) and 50kg (dynamic load during vehicle operation), effectively supporting the weight of the rear intake duct and resisting deformation caused by road vibrations or duct expansion/contraction. Finite Element Analysis (FEA) testing confirms the bracket can withstand continuous vibration (10-50Hz) for over 10,000 hours without fatigue cracking, ensuring long-term stability of the intake system

The bracket undergoes a hot-dip galvanization + electrostatic powder coating dual anti-corrosion process, compliant with automotive industry anti-rust standards (GB/T 13912-2022). The hot-dip galvanized layer (thickness: 80-100μm) forms a dense zinc-iron alloy coating that prevents steel oxidation, while the electrostatic powder coating (epoxy resin material, thickness: 60-80μm) adds an additional barrier against chemical corrosion (e.g., road salt, engine oil, and coolant). The bracket passes 1,000-hour neutral salt spray testing without red rust, making it suitable for harsh working environments like construction sites or coastal areas with high humidity

The bracket is manufactured with high-precision stamping and machining processes, ensuring a dimensional tolerance of ±0.3mm for key mounting and clamping positions. The duct clamping area features a semi-circular arc design with a rubber anti-slip pad (EPDM material), which not only ensures the intake duct is centered and fixed (preventing lateral displacement) but also reduces vibration transfer between the bracket and duct. This precise positioning maintains the intake duct’s original airflow path, avoiding airflow resistance increases caused by duct misalignment and ensuring stable engine air supply

Designed for user-friendly installation, the bracket comes with pre-assembled rubber gaskets (for reducing metal-to-metal vibration) and matching M10 hexagon bolts (with lock washers to prevent loosening). The entire installation process takes 15-20 minutes with basic tools (socket wrench and screwdriver), requiring no specialized skills. Additionally, the bracket’s rubber anti-slip pad and the flexible connection between the bracket and chassis effectively absorb 30% of road vibrations, preventing the intake duct from rubbing against other components or developing cracks due to long-term vibration, thus extending the service life of the entire intake system
