What is the Sitrak MCP Center Axle Drive Assembly (I=1.333,Kv180)

  • The Sitrak MCP Center Axle Drive Assembly (I=1.333,Kv180) is a high-performance, precision-engineered component designed to provide exceptional power transfer and reliability for heavy-duty vehicles. With its advanced design and robust construction, this assembly is built to withstand the toughest operating conditions, ensuring smooth and efficient operation of the vehicle’s drivetrain.
  • The Name and Nameplate of the assembly serve as important identification features, providing essential information about the product. The Rivet for nameplate–Rivet GB827-86-2.5*6 securely attaches the nameplate, ensuring it remains in place during operation. The Bevel Gear Sub-parameter Table(28/21) offers detailed specifications for the bevel gears, enabling precise adjustment and maintenance.
  • A series of Lock nuts are used throughout the assembly to prevent components from loosening under high torque and vibration. The Passive cylindrical gear(Z=32) and Active cylindrical tooth assembly (Z=32) work in tandem to transmit power efficiently, while Tapered roller bearings 32313 BJ2, 32314 BJ2, 32017X, 32020, 31313, and 32215 provide stable support and reduce friction, enhancing the durability and lifespan of the assembly.
  • The Adjustment spacer set – Main reduction bearing and Adjustment shim set-main bevel gear allow for precise calibration of the gears, ensuring optimal meshing and power transfer. Spacer and Thrust shims further contribute to the proper alignment of components, while the Oil catch plate helps to collect and direct lubricating oil, ensuring proper lubrication of the moving parts.
  • The Center axle main reduction housing assembly forms the structural backbone of the drive assembly, providing a sturdy foundation for all components. The Differential housing and Interaxial differential housing house the Half shaft gear, Planetary gear, Cross shaft, and Planetary wheel shaft (188.6mm/85.8mm), facilitating smooth power distribution between the axles. The Planetary wheel spacer ensures proper spacing of the planetary wheels, optimizing the differential’s performance.
  • To ensure secure fastening, a variety of bolts and studs are used, such as the Hexagonal flange end studs with teeth M16X1.5X75-12.9-MAN183-PHR, Hexagonal flange face toothed bolt M8X16-10.9-MAN183-B1, 6RD-SCHRAUBE B M8X 35-8.8-MAN183-B1 Cylinder head attachment bolt, M82016-MAN222-Mk8-10.9-MAN183-B1 bolts, and Hexagon head bolts M12X1,5X 35-10.9-MAN183-PHR. These fasteners, along with Locking plate and Lock plate, ensure that all components remain firmly in place. 
  • The Engaging sleeve, Forks, Toggle Fork, and related components are crucial for the shifting mechanism, allowing for smooth engagement and disengagement of gears. The Cylinder head, Cylinder liner, 34X3 B-NBR 3-70 Piston O-ring, and other hydraulic components work together to provide the necessary force for gear shifting.
  • The Input shaft and Flange assembly KV180 are responsible for receiving power from the transmission and transmitting it to the drive assembly. The Thrust cylindrical roller bearing 70×100 supports the input shaft, reducing axial loads. The Oil seal prevents lubricating oil leakage, while the Oil shield protects components from dirt and debris.
  • The Rear half shaft gear assembly and S=4,00 shims play important roles in power transmission to the rear wheels. The Main reduction housing cover is secured with Locating pin and bolts, providing access for maintenance and inspection. The Hexagon socket head tapered screw plug DIN906-M24X1.5-st and Magnetic hexagon socket cone screw plug assembly M24x1.5 DIN158 are used for oil filling and draining, ensuring proper maintenance of the assembly.
  • In summary, the Sitrak MCP Center Axle Drive Assembly (I=1.333,Kv180) is a comprehensive and reliable solution for heavy-duty vehicle drivetrains. With its high-quality components, precise engineering, and robust construction, it offers excellent performance, durability, and ease of maintenance, making it an ideal choice for commercial vehicle operators seeking optimal drivetrain performance.
