Dongfeng xinjiang truck parts Upper thrust rod bracket 2931247-HY22DNY

Built to withstand the extreme forces of truck suspension systems—including axial thrust, lateral torsion, and road impact—this bracket features a reinforced Q355ND low-alloy high-strength steel structure. The main body (12mm thick) delivers a minimum yield strength of 355MPa and tensile strength of 470-630MPa, enabling it to handle a maximum axial load of 80kN (equivalent to 8 tons) without permanent deformation. Key stress points—including the pin bore periphery and mounting hole edges—are reinforced with 8mm-thick steel ribs, which distribute torsional forces evenly and prevent cracking under heavy-haul conditions. Unlike ordinary carbon steel brackets, Q355ND’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 upper thrust rod remains securely anchored, maintaining proper wheel alignment and reducing suspension wear during long-haul transportation

Engineered to resist corrosion from road salt, mud, rain, and chassis grease—major threats to 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 or fading even after prolonged exposure to harsh chemicals. 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 the bracket remains corrosion-free for over 8 years in coastal areas, rainy regions, or winter roads with deicing salt. The pin bore is coated with anti-seize compound, preventing rust buildup and ensuring smooth thrust rod movement during suspension articulation

Designed to optimize suspension functionality, the bracket undergoes CNC machining to achieve strict dimensional accuracy and structural refinement. The pin bore has a tolerance of ±0.1mm and a surface roughness of ≤0.8μm, ensuring a tight fit with the thrust rod pin while allowing smooth rotational movement (critical for suspension flex). 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. The bracket’s profile is optimized for weight reduction (total weight: 3.2kg) without compromising strength, reducing unnecessary chassis load and improving fuel efficiency. Additionally, the bracket’s edges are rounded (radius: 3mm) to prevent damage to adjacent suspension components (e.g., rubber bushings) during installation or suspension movement. This precision and optimization ensure the suspension system operates with minimal friction and maximum stability

Designed for efficient installation and future maintenance, the bracket features a user-friendly design that simplifies setup and inspection. The package includes 4 galvanized M16×40 high-strength bolts, lock washers, and flat washers that match the factory thread specifications (grade 10.9 for heavy load-bearing). Installation steps are straightforward: align the bracket’s pin bore with the upper thrust rod, secure the bracket to the chassis frame using the included bolts, and torque to the recommended 180-200N·m with a torque wrench. No specialized tools are required, and one technician can complete installation in 30 minutes or less. The bracket’s design also allows easy access to the thrust rod bushing 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
