What is the Sitrak MAT16ZG Rear Axle Hub And Brake(Wheelbase 1850,Abs,Wear Alarm)

  • The Sitrak MAT16ZG Rear Axle Hub And Brake system with a wheelbase of 1850, equipped with ABS and wear alarm, is a state – of – the – art component designed for high – performance and reliability in heavy – duty vehicles. This assembly is a complex combination of numerous parts, each playing a crucial role in ensuring the efficient operation of the rear axle.
  • The Rear Hub Assembly (ABS) is at the core of this system. It integrates advanced ABS technology to enhance braking safety. The Seal Ring is used to prevent the leakage of lubricants and contaminants, maintaining the integrity of the hub assembly. The Spacer assembly (ABS) precisely positions components within the hub, ensuring proper alignment for the ABS system to function optimally.
  • The Axle Seal and Oil Retaining Disk work together to keep the axle lubricated and free from debris. Tapered roller bearings 30222 and 32222 provide smooth rotation and support the weight of the vehicle. These bearings are designed to handle high radial and axial loads, ensuring long – term durability.
  • Fastening components are equally important. Hexagon socket cone screw plug DIN906 – M24X1.5 – st and Magnetic hexagon socket cone screw plug assembly M24x1.5 DIN158 are used to seal openings and prevent the ingress of dirt. The End cap assembly, along with the End cap top pin, protects the inner components of the hub. Hexagon head bolts M10 secure various parts together, providing a stable connection.
  • The Wheel side reducer housing assembly is a key part of the power – transmission system. Inner gear ring (Z = 57), Sun wheel (Z = 23), and related components like the Shaft retaining ring, Gear ring holder assembly, and Sun wheel washer work in harmony to reduce speed and increase torque.
  • On the braking side, the Rear brake drum is the main friction surface for braking. Brake dust covers (left and right) protect the braking components from dust and debris. Plug DM8mm, Hexagon head bolt M8, and Spring washers are used for securing the dust covers.
  • The Brake Base Plate provides a stable platform for the braking mechanism. The ABS sensor output protection sleeve safeguards the ABS sensor, while the Limit warning device alerts the driver when the brake pads are worn.
  • Brake shoe with lining assembly, Pivot pin, Flexible Cylindrical Pins, Roller, and Return springs are all part of the braking actuation system. Brake camshafts (left and right) are responsible for applying the braking force, and the Automatic brake clearance adjusting arms (left and right) ensure consistent braking performance.
  • Camshaft bracket assemblies (left and right) support the camshafts, and various pins, bushings, and retaining rings keep the components in place. Washers, Adjusting washers, and Spring retainer for shaft are used for fine – tuning the assembly.
  • Hexagon head bolts M161.535 are used for heavy – duty fastening, and Type 1 hexagonal nut M8 is used in conjunction with the M8 bolts. Grease nipple assembly (AM8*1 D71412) allows for easy lubrication.
  • Adjustment shims and gaskets of various thicknesses, such as Adjustment shim (Thickness 0.1), Adjustment shim (Thick 0.15), Adjustment shim (Thick 0.4), Adjustment gasket (Thick 1.0), are used to achieve the precise clearance and alignment required for optimal performance. Hexagon head bolts M14*1.5 are also employed in different parts of the assembly for secure fastening.
  • In conclusion, the Sitrak MAT16ZG Rear Axle Hub And Brake system with its wide range of components is a highly engineered solution that offers superior performance, safety, and durability for heavy – duty vehicles.
