Dongfeng KR truck spare parts intake inlet pipe Upper bracket assembly 1109824-C5101

Built to solve the inefficiency of separate bracket components, this assembly features a pre-assembled, all-in-one structure that simplifies maintenance. It integrates four core parts: a Q355B steel main bracket, two EPDM rubber anti-vibration pads (10mm thickness), four galvanized mounting bolts, and two lock washers. Each component is pre-sized and pre-positioned—rubber pads are bonded to the bracket’s pipe cradle via heat-resistant adhesive, and bolts are sorted by length for chassis/pipe connections. This design eliminates the need for technicians to source or match parts, cutting installation preparation time from 45 minutes to 10 minutes. The integrated structure also reduces human error: pre-aligned bolt holes ensure the intake pipe is mounted at the correct 12° angle, avoiding airflow turbulence caused by misalignment

Engineered to bear the intake pipe’s weight and mitigate engine vibration, the assembly combines high structural strength with targeted shock absorption. The main bracket is made of Q355B high-strength steel (tensile strength 510-660MPa) with a 14mm-thick stress zone and integrated reinforcing ribs, supporting static loads up to 60kN without deformation. The EPDM rubber pads (Shore hardness 55±5) between the bracket and pipe reduce vibration transmission by 75%, preventing metal-to-metal wear and pipe fatigue. Finite element analysis confirms the assembly withstands 1 million vibration cycles (5-2000Hz, ISO 16750-3) without cracking, ensuring the intake pipe remains securely fastened even during off-road or heavy-load operation—avoiding air leaks that reduce engine power by 3-5%

The assembly’s performance is enhanced by CNC precision machining and a multi-layer anti-corrosion system. The bracket’s arc-shaped pipe cradle has a radius tolerance of ±0.3mm, ensuring full contact with the intake pipe (65mm outer diameter) and even load distribution. Bolt holes (M10 threads) are processed via rolling tapping, achieving 6H precision to prevent thread stripping. For corrosion resistance, the bracket undergoes zinc phosphate pretreatment, electrophoretic coating (80μm), and powder coating (60μm)—passing 1500-hour salt spray testing (ASTM B117) with no red rust. Rubber pads resist oil, coolant, and high temperatures (operating range -40℃ to 120℃), maintaining elasticity for ≥150,000km—matching the truck’s service life

Optimized for fleet efficiency, the assembly features a plug-and-play design that minimizes downtime. The pre-assembled bracket aligns with the engine compartment’s original mounting holes, and bolts require only a torque wrench (45-50N·m) for secure fixation. A single technician can complete installation in 20 minutes—50% faster than using separate components. Clear laser markings (“TOP”/“PIPE SIDE”) prevent reverse installation, and the integrated rubber pads eliminate the need for additional gaskets or adhesives. From a cost perspective, the assembly reduces total maintenance costs by 30%: it avoids the waste of mismatched parts, reduces labor time, and extends the intake pipe’s lifespan by preventing vibration damage. It comes with a 1-year/100,000km warranty, ensuring reliable performance for fleet operations
