What is the Shacman X6000 Rear Suspension (DC9X259521204)？

  • The Shacman X6000 Rear Suspension (DC9X259521204) is a rugged, high-performance system engineered to handle extreme loads, absorb road shocks, and deliver unmatched stability for heavy-duty trucks. Designed with precision components that prioritize durability and reliability, this suspension integrates advanced engineering to optimize ride quality and structural integrity. Below is a detailed breakdown of its key components:​
  • 1. V Rod​
  • The V Rod (vertical rod) serves as a critical linkage between the rear axle and the vehicle frame, transmitting vertical forces while maintaining proper suspension geometry. Constructed from forged high-strength steel, it features heat-treated ends to resist bending and fatigue, ensuring consistent load distribution during acceleration, braking, and cornering.​
  • 2. Hexagon Head Bolt – Fine Thread​
  • These fine-thread hexagon bolts (e.g., M14×1.5) are used for precision fastening in critical suspension joints, offering superior torque control to prevent over-tightening. The fine thread pitch reduces thread stripping risks, while the hexagon head design allows easy installation with standard tools, essential for maintaining secure connections in high-vibration environments.​
  • 3. DTF Hexagon Nut With Collar M18×1.5​
  • Engineered for heavy-duty applications, the DTF Hexagon Nut With Collar M18×1.5 features an integral collar that enhances load distribution across mating surfaces, reducing indentation and improving shear resistance. The DTF (Direct Thread Forming) technology ensures durable thread engagement, making it ideal for securing major suspension components like the axle and spring brackets.​
  • 4. Hexagon Bolt With Shoulder M7.015.01 M20×2×75-10.9-ZNPHR 3F​
  • This specialized bolt includes a precision-machined shoulder that acts as a 定位 pin, ensuring accurate alignment between components like the trunnion shaft housing and frame. Rated at 10.9 strength class with a zinc-phosphate coating (ZNPHR 3F), it offers exceptional tensile strength and corrosion resistance, vital for load-bearing joints.​
  • 5. Hexagon Flange Toothed Bolt – Fine Thread​
  • Featuring a serrated flange to grip surfaces and prevent rotation, these bolts provide vibration-resistant fastening for secondary components such as spring clamps and brackets. The fine thread design (e.g., M14×1.5) allows precise torque application, ensuring secure connections without compromising thread integrity.​
  • 6. Rear Leaf Spring Assembly​
  • The Rear Leaf Spring Assembly is the core load-bearing component, consisting of multiple layered steel springs that absorb shocks and distribute weight evenly. Heat-treated and shot-peened for enhanced fatigue resistance, it works with the rubber bolster assembly to dampen vibrations, improving cargo protection and ride comfort even on uneven terrain.​
  • 7. Trunnion Shaft Bracket & Housing​
  • The Trunnion Shaft Bracket provides a rigid mount for the trunnion shaft, while the Housing encloses the conical bearing to protect it from debris. Both components are fabricated from nodular cast iron, offering high strength and wear resistance. The shaft’s precision alignment ensures smooth suspension articulation under heavy loads.​
  • 8. Conical Bearing & Bearing Cover​
  • The Conical Bearing enables controlled rotation of the trunnion shaft, minimizing friction during suspension movement. Encased in a robust Bearing Cover, it is sealed to prevent dust and moisture ingress, extending service life. The bearing’s tapered design withstands radial and axial loads, critical for maintaining suspension efficiency.​
  • 9. U-Bolt & Spring Clamp​
  • U-Bolts securely fasten the leaf spring to the axle, while Spring Clamps maintain proper spring alignment and spacing. Made from quenched-and-tempered steel, these components feature a galvanized finish to resist rust, ensuring long-term reliability in harsh conditions. Their curved design distributes clamping force uniformly across the spring surface.​
  • 10. Spherical Seat Nut M27×2​
  • Designed for the suspension’s articulating joints, the Spherical Seat Nut M27×2 provides a smooth, low-friction interface for spherical bearings. The fine pitch (M27×2) allows precise adjustment of bearing preload, ensuring consistent movement and reducing wear on connected components like the V rod and lower I rod.​
  • 11. High Strength Washer-24​
  • These 24mm high-strength washers are placed under bolt heads and nuts to distribute clamping force over a larger surface area, preventing damage to mating components. Constructed from 硬化 steel, they enhance joint stability and reduce the risk of fastener loosening in high-stress applications.​
  • 12. Bumper Assembly & Rubber Bolster Assembly​
  • The Bumper Assembly acts as a mechanical stop to prevent over-compression of the leaf spring, while the Rubber Bolster Assembly cushions impacts during heavy loading. The rubber bolster’s dual-layer design absorbs high-frequency vibrations, reducing noise and protecting the suspension from sudden shocks, ideal for off-road operations.​
  • 13. Lower I Rod​
  • The Lower I Rod (lateral rod) stabilizes the rear axle laterally, preventing side-to-side movement during cornering. Fabricated from hollow extruded steel for a strength-to-weight balance, it features adjustable ends to fine-tune suspension alignment, ensuring optimal handling and tire contact with the road.​
  • 14. Self-locking Thin Nut​
  • Used in space-constrained areas, the Self-locking Thin Nut provides secure fastening without adding excess weight. Its nylon insert locks onto threads to prevent loosening from vibrations, making it ideal for secondary components like brake line brackets and sensor mounts where reliability and compactness are essential.​
  • 15. Hex Socket Head Bolt​
  • These bolts feature a recessed hexagonal drive for a flush, low-profile installation, often used in areas with limited clearance. The socket design allows high torque application without damaging the fastener, ensuring secure attachment of components like the bearing cover and trunnion brackets.​
  • The Shacman X6000 Rear Suspension (DC9X259521204) combines these components into a cohesive system that excels in load-bearing capacity, durability, and ride control. Each part is rigorously tested for fatigue resistance, corrosion tolerance, and dimensional precision, adhering to international standards for commercial vehicle suspensions. Regular maintenance—including torque checks for fasteners, lubrication of moving joints, and inspection of wear components—will maximize performance and extend the suspension’s service life, ensuring reliable operation in the most demanding heavy-duty applications.​
