Dongfeng Xinjiang X7 truck parts bumper Central middle bracket assembly 8406230-TXGG01Y

Built to serve as the core load-bearing component for the X7’s front bumper, this bracket assembly delivers exceptional support performance. It is fabricated from Q355B low-alloy high-strength steel (8mm thick for the main body, 10mm thick for stress-concentrated areas) with a tensile strength of ≥470MPa and yield strength of ≥355MPa—enabling it to bear the bumper’s central weight (up to 40kg) plus distribute lateral/vertical forces from road impacts. The bracket’s structure integrates a crosswise reinforcement beam (spanning 280mm) and two vertical support legs, forming a triangular load-bearing system that prevents the bumper from sagging or tilting under long-term use. Unlike ordinary carbon steel brackets, Q355B’s low-temperature toughness (-40℃ impact energy ≥34J) ensures stability in freezing regions, critical for the X7’s all-weather operation

Designed to absorb and disperse impact energy during minor collisions, the bracket assembly features a factory-optimized impact-resistant structure. The central reinforcement beam is engineered with a slight arc (radius: 150mm) that deforms elastically under low-impact forces (≤600N), reducing damage to the bumper’s plastic shell and the chassis frame. Key connection points (between the bracket and chassis) are equipped with 3mm-thick rubber gaskets that act as shock absorbers, damping 30% of impact vibrations before they transfer to the chassis. Additionally, the bracket’s edges are rounded (radius: 5mm) to avoid puncturing the bumper’s protective coating during deformation—extending the bumper’s service life. In impact tests, the bracket maintains structural integrity after 50+ minor collision cycles (equivalent to low-speed contact with obstacles), minimizing repair costs

Engineered to resist corrosion from road salt, rain, mud, and stone chips (common in the bumper’s central position), the bracket assembly features a professional three-layer anti-corrosion system. First, a zinc phosphate pretreatment layer (12μm) is applied to the steel surface to block rust at the substrate. Then, a high-temperature electrostatic powder coating (90μm) with epoxy-polyester composite is baked on—forming a scratch-resistant, waterproof barrier that resists peeling even after prolonged UV exposure. Finally, a clear chromate passivation layer enhances coating adhesion and chemical resistance. This system passes 1500-hour salt spray testing (per ASTM B117) with no red rust, ensuring durability for over 10 years in coastal areas, snowy regions, or construction sites. All mounting holes are pre-coated with anti-seize compound, preventing thread rust and enabling easy disassembly during maintenance

Designed for efficient installation on the Dongfeng Xinjiang X7, the bracket assembly undergoes CNC cutting, drilling, and bending to achieve strict dimensional accuracy (length/width tolerance: ±0.3mm, hole position tolerance: ±0.1mm). The package includes 6 M10×25 galvanized bolts (for bumper connection) and 4 M12×35 grade 10.9 high-strength bolts (for chassis attachment)—matching the X7’s factory hardware specifications. Installation steps are straightforward: align the bracket’s chassis holes with the X7’s front central beam pre-drilled points, secure with M12 bolts (torque to 55-60N·m), then attach the bumper’s central section to the bracket using M10 bolts (torque to 30-35N·m). No specialized tools are required, and a professional technician can complete the process in 30 minutes or less. The bracket also includes engraved alignment marks (“CENTER” and “TOP”) to prevent incorrect installation, ensuring the bumper’s central position is precise on the first attempt—reducing labor costs and minimizing truck downtime
