DZ9114320287 Middle Axle Main Reducer Assembly Product DescriptionI. Product OverviewDZ9114320287 Middle Axle Main Reducer Assembly is a core transmission component specially designed for heavy-duty vehicles. It is mainly adapted to the middle axle drive system and undertakes the key functions of reducing speed, increasing torque and changing the direction of power transmission. It is widely used in various types of heavy-duty trucks, engineering vehicles and other models. It is a core assembly component ensuring efficient power transmission and stable driving of vehicles, with both reliability and practicality, suitable for various complex working conditions.II. Product Features

• Compact and Reasonable Structural Design: Adopting an integrated shell design, it integrates core components such as reducer shell, inter-axle differential, main reducer and wheel-side differential. The layout is scientific and the space occupation is small. At the same time, the internal structure is optimized to reduce friction loss between components, improve transmission fluency, and adapt to the limited installation space of heavy-duty vehicles.
• Advanced Gear Technology: The core transmission gears are forged from high-strength materials, processed through precision machining and heat treatment processes, with high tooth surface smoothness and excellent meshing accuracy. The driving bevel gear and driven bevel gear adopt a zero offset design, which can be post-heat trimmed through gear grinding process, greatly improving the gear transmission efficiency and service life, and reducing operating noise.
• Strong Load-bearing and Anti-load Capacity: Adopting the main reducer and wheel-side two-stage reduction structure, the maximum output torque of the whole axle can reach 70000N.m. Equipped with a cast axle housing, it has higher rigidity and smaller bending deformation, which can effectively bear the heavy load and impact load during the driving of heavy-duty vehicles, and adapt to high-intensity operation requirements under complex road conditions.
• Excellent Protection Performance: The shell adopts a sealed design, which is waterproof, dustproof and oil-proof, effectively isolating external impurities from entering the interior, protecting core components such as gears and bearings from wear, adapting to harsh working environments such as high temperature, humidity and dust, and reducing the failure rate.
• Optimized Differential Lock Design: Equipped with built-in inter-axle differential lock and wheel-side differential lock, it has a more compact structure, higher transmission efficiency and stronger self-protection ability. It can automatically or manually lock the differential according to road conditions, improve the passability of the vehicle under complex road conditions such as mud and climbing, avoid wheel slipping, and ensure driving stability.

IV. Product Advantages

• High Transmission Efficiency: The optimized gear meshing design and compact structural layout reduce energy loss during power transmission. The transmission efficiency is significantly higher than that of ordinary main reducers, which can effectively reduce vehicle fuel consumption, improve the stability and timeliness of power output, and at the same time reduce operating noise and improve driving comfort.
• Long Service Life: Core components are made of high-strength materials and advanced processing technology. The gears have excellent wear resistance and impact resistance. The sealed protection design is in place to reduce component wear, extend the service life of the assembly, and reduce the cost of later maintenance and replacement. At the same time, the application of post-heat trimming process further improves product consistency and durability.
• Wide Adaptability: Compatible with various heavy-duty vehicle middle axle systems, the gear ratio can be flexibly adapted to different transportation scenarios. Whether it is high-speed driving or low-speed heavy load, it can meet the vehicle power requirements. At the same time, the high ground clearance is suitable for complex operating environments such as fields and construction sites, with strong environmental adaptability.
• Easy Installation: Strictly mold-produced according to original vehicle data, with high dimensional accuracy. The mounting holes and connection parts are completely matched with the original vehicle, no additional debugging is required, the installation process is simple and efficient, the replacement and assembly can be completed quickly, saving maintenance man-hours, reducing installation costs, and adapting to the original vehicle maintenance and replacement needs.
• Outstanding Reliability: After strict performance testing and working condition simulation, the product has strong stability and low failure rate, and can withstand the test of long-term heavy load and complex road conditions. The self-protection function of the built-in differential lock further improves the reliability of product operation, reduces the downtime caused by faults, and ensures the normal operation of the vehicle.
• Excellent Cost Performance: Compared with similar products, while ensuring high strength and high reliability, it takes into account the cost advantage. The later maintenance is convenient and the maintenance cost is low, so the long-term use cost performance is higher. At the same time, the standardized design can be compatible with various control systems, with strong versatility, reducing the user's comprehensive use cost.
