Foton Auman Hub Reduction Gear Module

The Foton Auman Hub Reduction Gear Module is a sophisticated and durable component designed for heavy-duty trucks. It is specifically engineered to enhance the performance and reliability of the vehicle’s rear axle system. The module is constructed from high-quality materials, ensuring longevity and robust operation under various conditions. The key components and their functions are detailed below.

Product Parameters of Foton Auman Hub Reduction Gear Module

Rear Axle and Hub Assembly
The rear axle of the Foton Auman Hub Reduction Gear Module is a 5.73 ratio, widened, and made from cast steel, providing exceptional strength and stability. The rear hub assembly includes the rear hub, wheel bolt, and wheel nut. These components are essential for securely mounting the wheels and ensuring smooth rotational movement. The module features multiple seal gaskets and a splash cover to protect the internal components from contaminants and moisture, maintaining optimal performance and extending the service life of the gear module.
Seals and Gaskets
Several seal gaskets are integrated into the module to ensure a tight and secure fit, preventing lubricant leaks and ingress of debris. The module includes shaft seal gaskets, which are crucial for maintaining the lubrication of the bearings and preventing contamination. These gaskets are strategically placed to ensure the highest level of protection for the internal components.
Bearings and Mounting Hardware
The module employs single row radial conical roller bearings, which are designed to handle high radial and axial loads, ensuring smooth and efficient operation. The mounting hardware includes hexagon head bolts, spacer rings, and cylindrical pins, which are used to secure and align the various components of the module. The bearings are precision-engineered to provide reliable performance and long service life.
Planetary Gear System
The hub reduction gear module features a planetary gear system, which includes the hub planetary wheel (Z=16), needle bearing, hub planetary wheel washer, planetary gear shaft, and internal gear ring (Z=57). The sun gear (Z=23) and sun gear washer (Z=23) are also integral parts of the system, working in tandem to achieve precise and efficient gear reduction. The shaft retaining ring and ring gear bracket assembly ensure the stability and alignment of the planetary gear system, enhancing the overall performance and reliability of the module.
Differential and Support Components
The module includes an inter-axle differential assembly, which consists of the differential lock assembly, inter-axle gear differential assembly, and inter-axle differential housing assembly. These components work together to distribute power evenly between the wheels, improving traction and handling. The lower thrusting rod support bases (LH and RH) and studs provide additional support and stability to the differential system, ensuring optimal performance under heavy loads.
Hydraulic and Control Components
The differential lock cylinder block, piston, O-ring seal, and cylinder gasket are essential components of the hydraulic system, which enables the differential lock to engage and disengage as needed. The shift rail, pressure switch, shift fork retracting spring, and shift fork are part of the control mechanism, allowing the driver to engage the differential lock manually. The hexagon head thin nut and tightening screw with slotted flat end are used to secure the control components, ensuring a secure and reliable operation.
Conclusion
The Foton Auman Hub Reduction Gear Module is a high-performance, robust, and reliable component designed to meet the demanding requirements of heavy-duty trucks. Its advanced design and high-quality materials ensure optimal performance, durability, and efficiency. Whether for on-road or off-road applications, this module is a critical component that enhances the overall performance and reliability of the vehicle’s rear axle system.
