What is the Sitrak C7h-F Cab Suspension (Coil Springs/850/Lower +80/Engine Suspension Forward 70/Wp)

  • The Sitrak C7h – F Cab Suspension (Coil Springs/850/Lower +80/Engine Suspension Forward 70/Wp) is a high – performance suspension system meticulously engineered to deliver superior stability, durability, and comfort for commercial vehicles. This advanced suspension setup integrates a comprehensive range of components, each designed to withstand the rigors of heavy – duty use while optimizing vehicle handling and ride quality.
  • At the core of the system, the Front Suspension Coil Spring Damper Assembly for L32 Series Cabs and L32/40 series cab rear suspension coil spring damper assembly work in harmony to absorb shocks and vibrations from the road. These assemblies feature robust coil springs that provide the necessary elasticity, while the dampers ensure controlled movement, reducing bounce and sway. The Front Suspension Limit Plate and Limit washer play crucial roles in preventing over – extension of the suspension components, safeguarding the system from damage during extreme conditions.
  • A variety of brackets and mounting components are essential for the proper installation and function of the suspension. The Cab Rear Suspension Lower Bracket Assembly(C7H/850/WP), Cab Rear Suspension Left Upper Bracket Welding Assembly(C7 Low Floor/WP), and Cab rear suspension right upper bracket welding assembly (C7 low floor/WP) (symmetrical with the left part) form the structural foundation for the rear suspension. Similarly, the Cab front suspension damper left upper bracket, Cab front suspension damper right upper bracket, Cab front suspension arm assembly, and related brackets such as the Low – floor cab front suspension arm bracket, Cab front suspension arm right transition bracket, and Cab Front Suspension Arm Left Transition Bracket are key elements of the front suspension setup. These brackets are constructed from high – strength materials, ensuring they can withstand the immense forces exerted during vehicle operation.
  • To ensure a secure and stable installation, an array of specialized fasteners is utilized. Hexagonal flange bolts with teeth in various sizes, including M12*1.25, M16*1.5, and M14*1.5, along with their corresponding Hexagonal flange nuts with teeth, provide a high – torque, vibration – resistant connection. For example, the Hexagonal flange bolts with teeth M14*1.5 and Hexagonal flange nuts with teeth M14*1.5 are repeatedly employed across different components, ensuring a uniform and reliable fastening system. Other fasteners such as Hexagon head flange bolts (MAN222 – M12X1,5X25H – MK14X4 – 10.9 – MAN183 – B1), Hexagonal flange face bolts M10, and All – metal hexagonal flange lock nuts further enhance the integrity of the assembly. The Embedded lock washers (M16) and Limit washer add an extra layer of security, preventing nuts and bolts from loosening over time.
  • Additional components contribute to the overall functionality and safety of the suspension. The Hydraulic lock assembly provides enhanced control and stability, while the Noise Reduction Block/81962100462 minimizes unwanted vibrations and noise, creating a quieter cabin environment. The Lift cylinder replacement warning sign serves as a safety reminder during maintenance, ensuring technicians follow proper procedures.
  • In summary, the Sitrak C7h – F Cab Suspension is a cutting – edge solution that combines robust construction, advanced engineering, and secure fastening systems. With its carefully selected components and precise design, this suspension system offers commercial vehicle operators reliable performance, improved handling, and extended component lifespan, making it an ideal choice for demanding transportation applications.
