What is the Sitrak Mat16 Center-Axle Drive Unit (I=1.381, Xsφ180, Output Xsφ165)

  • Sitrak Mat16 Center-Axle Drive Unit (I=1.381, Xsφ180, Output Xsφ165)

  • The Sitrak Mat16 Center – Axle Drive Unit with the specifications of I = 1.381, Xsφ180, and an output of Xsφ165 is a state – of – the – art product designed to provide efficient power transmission and reliable performance in heavy – duty vehicles. This drive unit is composed of a series of carefully engineered components that work in synergy to ensure smooth operation.
  • At the core of the unit is the MAT16 center bridge middle section with a gear ratio of i = 1.381 and an input shaft diameter of XSφ180. This middle section is the heart of the power – transfer mechanism, precisely designed to distribute torque effectively and optimize the vehicle’s driving performance.
  • The thru – axle plays a vital role in connecting different parts of the drive unit. It provides a stable and continuous path for power transmission, ensuring that the rotational force is transferred smoothly from the input to the output.

  • Sitrak Mat16 Center-Axle Drive Unit (I=1.381, Xsφ180, Output Xsφ165)

  • The flange assembly is used to connect various components securely. It provides a reliable interface between different parts, minimizing the risk of power loss due to loose connections. The bearing cap is installed to protect the bearings and maintain their proper alignment. It helps to reduce friction and wear, thereby extending the lifespan of the bearings.
  • Flange nuts are used to fasten the flange assembly tightly. Along with the cotter pin, they ensure that the connection remains secure even under high – stress conditions. The cotter pin prevents the flange nut from loosening due to vibrations, adding an extra layer of safety to the drive unit.
  • Double row tapered roller bearings are employed to support the shafts and handle the radial and axial loads. These bearings are designed to withstand heavy – duty applications, providing high – precision rotation and reducing energy losses.

  • Sitrak Mat16 Center-Axle Drive Unit (I=1.381, Xsφ180, Output Xsφ165)

  • Hexagon head bolts M10, along with spring washers, are used for general fastening purposes. The spring washers help to maintain the tension of the bolts, preventing them from coming loose over time.
  • The sliding engagement sleeve and the fixed engagement sleeve are essential for the smooth engagement and disengagement of gears. They allow for seamless gear changes, enabling the vehicle to adapt to different driving conditions.
  • Thrust wires are used to provide additional support and stability to the components, especially in high – load situations. Shaft seals are installed at various points to prevent lubricant leakage and keep contaminants out. This helps to maintain the integrity of the drive unit and ensure its long – term performance.

  • Sitrak Mat16 Center-Axle Drive Unit (I=1.381, Xsφ180, Output Xsφ165)

  • The nameplate provides important information about the drive unit, such as its specifications and model number. It is securely attached using nameplate rivets (Rivet GB827 – 86 – 2.5*6), which are designed to provide a strong and durable connection.
  • In summary, the Sitrak Mat16 Center – Axle Drive Unit is a comprehensive and high – performance solution that combines advanced engineering and high – quality components. Each part is carefully designed and manufactured to ensure the reliability, efficiency, and longevity of the drive unit, making it an ideal choice for heavy – duty vehicles.
