Dongfeng Xinjiang truck parts Front suspension fixed end bracket 2901249-T5WF01Y

Built to withstand the extreme mechanical forces of truck front suspension systems—including axial load, lateral torsion, and road impact—this bracket features a reinforced Q355B low-alloy high-strength steel structure. The main body (10mm thick) delivers a minimum yield strength of 355MPa and tensile strength of 470-630MPa, enabling it to handle peak dynamic loads of up to 50kN (equivalent to 5 tons) without permanent deformation. Key stress points—including the pivot bore periphery and mounting hole edges—are reinforced with 12mm-thick triangular gussets, which distribute torsional forces evenly and prevent cracking under heavy-haul conditions. Unlike ordinary carbon steel brackets, Q355B’s low-temperature toughness (-40℃ impact energy ≥34J) avoids brittle fracture in freezing winter environments, critical for trucks operating in cold regions. This robust design ensures the front suspension remains securely anchored, maintaining wheel alignment and reducing suspension wear during long-haul or off-road transportation

Designed to optimize front suspension functionality, the bracket undergoes advanced structural engineering and CNC machining to achieve strict dimensional accuracy. The pivot bore is precision-honed to a surface roughness of ≤0.8μm and a roundness tolerance of ±0.1mm, ensuring smooth rotation with the suspension’s pivot pin (reducing friction and wear on rubber bushings). Mounting holes are drilled with a concentricity error of ≤0.2mm, guaranteeing perfect alignment with the chassis frame and avoiding forced assembly that could damage threads or distort the bracket. The bracket’s profile is optimized for weight reduction (total weight: 4.2kg) without compromising strength, reducing unsprung mass and improving ride comfort. Additionally, the bracket’s edges are rounded (radius: 3mm) to prevent damage to adjacent suspension components (e.g., shock absorber hoses) during installation or suspension articulation. This precision and optimization ensure the suspension system operates with minimal friction and maximum stability

Engineered to resist corrosion from road salt, mud, rain, and chassis grease—major threats to front suspension components—the bracket features a professional three-layer anti-corrosion system. First, a zinc phosphate pretreatment layer (10μm) is applied to the steel surface to block rust at the substrate. Then, a high-temperature electrostatic powder coating (80-100μm) with epoxy-polyester composite is baked on, forming a scratch-resistant, waterproof barrier that resists peeling even after prolonged exposure to harsh chemicals or UV radiation. Finally, a clear chromate passivation layer enhances coating adhesion and chemical resistance. This system passes 1200-hour salt spray testing (per ASTM B117) with no red rust, ensuring durability for over 8 years in coastal areas, rainy regions, or winter roads with deicing salt. The pivot bore is coated with anti-seize compound, preventing rust buildup and ensuring smooth pivot pin movement during suspension flex

Designed for efficient installation and future maintenance, the bracket features a user-friendly design that simplifies setup and inspection. The package includes 5 galvanized M16×45 high-strength bolts (grade 10.9), lock washers, and flat washers that match the factory thread specifications for heavy load-bearing. Installation steps are straightforward: align the bracket’s pivot bore with the front suspension’s pivot pin, secure the bracket to the chassis frame using the included bolts, and torque to the recommended 200-220N·m with a torque wrench. No specialized tools are required, and one technician can complete installation in 40 minutes or less. The bracket’s design also allows easy access to the suspension’s rubber bushings for inspection or replacement (no need to remove the entire bracket), reducing maintenance time. For repair shops or truck operators, this easy installation and maintenance design reduces labor costs and minimizes chassis downtime—critical for commercial trucks relying on daily transportation tasks
