Product Description

Product Description (Universal for All Differential Gearboxes)
This differential gearbox is a core transmission component specially designed for electric tricycles and light commercial vehicles, supporting a wide range of motor power (500W–2200W) and fully compatible with 48V/60V/72V systems. It is an ideal drive solution for 3-open tricycles, cargo vehicles, and utility electric vehicles.
Built with high-strength housing and precision gear sets, it delivers stable high torque output to enhance climbing and load capacity, perfectly meeting the demands of heavy-duty transportation scenarios. Optimized gear pairing ensures low-noise, smooth operation even under continuous full load, providing a reliable and comfortable riding experience.
The modular or fully enclosed design enables easy maintenance and reduces repair costs. Worn parts can be replaced individually without replacing the entire unit, minimizing downtime for fleet use. The sealed, anti-rust housing provides excellent protection against water, dust, and corrosion, ensuring stable performance in harsh outdoor conditions.
With industrial-grade components and standardized interfaces, it ensures long-term reliable operation, reduces overall maintenance costs, and serves as a cost-effective transmission solution for electric vehicle manufacturers and after-sales markets.
