What is the Sitrak Version 20 Standard Weight Mixing Disconnecting Balance Suspension (14 Square/38t/12×23×1350/Frame 850_8+5_casting Cross Member/Mat16bg/Four Riders/Plate Spring Distance 1030)

  • Sitrak Version 20 Standard Weight Mixing Disconnecting Balance Suspension (14 Square/38t/12×23×1350/Frame 850_8+5_casting Cross Member/Mat16bg/Four Riders/Plate Spring Distance 1030): Heavy-Duty Performance for Unmatched Stability​
  • Engineered to meet the extreme demands of 38-ton heavy-duty mixing trucks, the Sitrak Version 20 Standard Weight Mixing Disconnecting Balance Suspension is a high-precision solution designed for maximum load-bearing capacity and stability. With specifications like 14-square configurations, 12×23×1350 plate spring dimensions, an 850 frame with 8+5 leaf spring setup, and a 1030mm plate spring distance, this suspension system integrates a comprehensive suite of components to ensure seamless operation, even under the most challenging conditions.​
  • Load-Bearing and Spring Components​
  • The Rear plate spring assembly forms the core of the suspension’s load-bearing capabilities. Comprising 12 robust leaf springs, each 23mm thick and 1350mm long, it evenly distributes the 38-ton load across the axles. The Four Riding Bolt Ball Iron Plate Spring Press Block, secured by Flange Nut M24*3 and Rear Spring Riding Bolt, compresses the springs, ensuring optimal tension and shock absorption. A Guide pin and Guide plate facilitate smooth movement, reducing friction and wear during dynamic operations.​
  • Structural Support and Limiting Mechanisms​
  • Limit Block Assembly and Limit bracket, fastened with Hexagon head bolts M14*1.5, prevent overextension of the springs, safeguarding the suspension from damage under heavy loads. The Balance shaft with housing assembly serves as the central pivot point, transferring forces between the axles and springs. Its high-strength alloy construction, combined with Lower thrust rod assembly, enhances lateral stability, minimizing body roll during sharp turns or uneven terrain traversal.​
  • Mounting and Fastening Systems​
  • The Rear leaf spring left rear bracket and Rear leaf spring right rear bracket (symmetrical with left part) provide secure mounting points for the leaf springs. These brackets, bolted with Hexagon head bolt M14*1.5, ensure a rigid connection to the vehicle frame. The Rubber support assembly, secured by Hexagon head bolt M22*1.5, cushions vibrations, reducing noise and protecting the frame from stress-induced damage.​
  • Thrust Rod and Anti-Loosening Components​
  • The V-type thrust rod assembly, connected by V-type thrust rod bolts and reinforced with an Anti-loosening sleeve, stabilizes the rear axles, preventing unwanted movement during acceleration, braking, or cornering. Hexagonal flange face bolts M20*1.5, Hexagonal flange face nuts M20*1.5, and Double head studs with Spring washers create a secure, vibration-resistant connection for the thrust rods. The Hexagonal flange bolts with teeth M16*1.5 and Type 2 hexagon nuts M16*1.5 further reinforce critical joints, ensuring long-term reliability.​
  • Precision Fasteners and Design Excellence​
  • A variety of precision fasteners, including Hexagon socket countersunk head screws and Hexagonal flange nuts with teeth M16*1.5, are used throughout the assembly to ensure tight, reliable connections. Each component, from the Thrust rod front left bracket to the Garden post pin–Pin GB119 A20*24, undergoes rigorous testing for strength and durability, meeting or exceeding industry standards. The system’s casting cross member (Mat16bg) and four-rider design optimize weight distribution, enhancing overall efficiency and reducing wear on tires and axles.​
  • SEO-Optimized Features for Commercial Relevance​
  • Keyword Precision: Prioritizes product model, technical specifications, and component names to dominate exact-match searches in parts catalogs and technical databases.​
  • Technical Depth: Highlights material science (alloy steel, rubber supports), load-bearing capacity, and anti-loosening technologies to attract mechanical professionals and fleet managers.​
  • Benefit-Driven Messaging: Emphasizes stability, durability, and reduced maintenance, addressing core concerns for operators of heavy-duty mixing trucks.​
  • In summary, the Sitrak Version 20 Standard Weight Mixing Disconnecting Balance Suspension sets a benchmark for heavy-duty performance, combining rugged construction, advanced engineering, and precision components. Trust in its reliability to keep your mixing trucks stable, efficient, and on the road—even under the most punishing loads and conditions.
