Core Functions & Product Advantages

1. Core Power Transmission & Precise High-Low Speed Switching

   As the core driven component of the auxiliary transmission mechanism, it receives power input from the driving gear, and realizes seamless switching between high-speed cruising and low-speed heavy-duty working conditions with the shifting mechanism. In low-speed mode, it greatly amplifies output torque to meet the demands of climbing, heavy-load hauling, field operation and off-road traction. In high-speed mode, it optimizes transmission efficiency, cuts fuel consumption and improves highway driving performance.

2. Integrated Forging Design, High Strength & Impact Resistance

   Made of high-quality alloy steel with one-piece hot forging molding, the gear and shaft body are integrally formed without splicing, completely eliminating the risk of tooth stripping and shaft fracture. With high-frequency quenching treatment, the tooth surface has high hardness and superior wear resistance, which can withstand long-term heavy-load impact and adapt to continuous operation in harsh working conditions.

3. High-Precision Machining, Smooth Transmission & Low Noise

   Adopting precision CNC machining, the tooth profile meets international accuracy standards, and the meshing clearance is precisely controlled. It ensures smooth and stable transmission, greatly reduces gearbox vibration and noise during operation, and extends the overall service life of the gearbox.

4. Standardized OEM Matching, Easy Installation

   Produced in strict accordance with OEM specifications, the spline, tooth profile and installation dimensions are perfectly matched with the original vehicle auxiliary transmission system. No secondary modification is required, it can directly replace the original parts, with strong compatibility and convenient installation.
