130301000100A Transfer Case Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

130301000100A Transfer Case Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 130301000100A transfer case is an original core power distribution component, specially designed for Sany construction machinery equipment (compatible with SY series and other models). As the “power hub” of the four-wheel drive system, it can rationally distribute engine power to the front and rear axles, realize flexible switching between two-wheel drive and four-wheel drive, and is widely used in heavy construction machinery such as excavators and cranes. It is suitable for complex working conditions such as mines and construction sites, solves pain points such as uneven power distribution and switching jams, improves equipment passability, and extends the service life of the transmission system.
This transfer case boasts significant advantages. Constructed from a single piece of high-strength alloy steel, it features a built-in precision gear set and rigid locking structure, combining rigidity and distribution precision to achieve a 50:50 balanced power distribution. It also features torque amplification, significantly increasing wheel-end torque for low-speed four-wheel drive, easily handling complex road conditions. Optimized gear meshing design ensures smooth and noiseless transmission, while an internal lubrication system reduces wear. A sealed structure prevents dust and moisture ingress, and a standard mounting interface allows for quick connection to the gearbox and driveshaft; installation is as simple as bolting, improving assembly efficiency.
The product strictly adheres to original manufacturer standards and ISO international specifications, undergoes rigorous testing, and is resistant to high and low temperatures, aging, and corrosion. It is suitable for extreme operating conditions ranging from -40℃ to +120℃ and can operate stably in harsh environments for extended periods. Surface electrophoretic rust prevention treatment resists corrosion, and an internal lubrication system reduces maintenance frequency. Balancing practicality and economy, it is suitable for the high-intensity operation requirements of heavy equipment, preventing component damage caused by power distribution imbalances.

Core technical parameters:

-Model: 130301000100A
– Material: High-strength alloy steel (body) + precision alloy steel gears (internal core components)
– Surface treatment: Electrophoretic rust prevention, corrosion resistance, anti-aging, IP54 protection rating.
– Rated torque: 800-3000 N·m (suitable for power distribution requirements of heavy equipment)
– Operating temperature: -40℃～+120℃, suitable for extreme high and low temperature conditions.
– Power distribution ratio: Default 50:50, which can be flexibly adapted according to working conditions.
– Torque amplification ratio: 2.5:1-4:1 (low-speed four-wheel drive mode, improves off-road capability)
