Third Deneration Mini Spline Gearbox
Universal Compatibility
Perfectly adapted to 48V-72V wide voltage systems, compatible with 500W-3000W full-power range motors, and universally applicable to over 95% of electric tricycle rear axle interfaces on the market, with no modification required for installation.
Industrial-Grade Durability
It adopts high-strength cast aluminum / alloy shell and precision bearings. The industrial-grade component design ensures stable operation for more than 50,000 hours, with a long service life and low failure rate.
High Torque & Climbing Ability
The optimized gear ratio design enables quick starting and sufficient torque, easily handling heavy loads and uphill conditions in mountainous areas, ensuring stable and powerful operation even when fully loaded.
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.

Gearbox Advantages vs. Ordinary Products
| ✓ High-strength alloy housing, precision cast, impact-resistant and crack-proof | ✗ Ordinary cast iron/thin steel housing, prone to deformation and cracking |
| ✓ Precision gear set, wear-resistant material with high transmission efficiency | ✗ Roughly made gears, fast wear and large power loss |
| ✓ Low-noise design with sealed bearings, low operating decibel | ✗ No noise reduction design, loud operation and obvious vibration |
| ✓ Full-range compatibility for 48V-72V / 500W-2200W systems | ✗ Narrow voltage/power range with poor compatibility |
| ✓ Modular structure, easy to disassemble and maintain, reducing after-sales costs | ✗ Integrated structure, requiring full replacement for partial damage |
| ✓ Anti-rust and sealed treatment, waterproof/dustproof for harsh environments | ✗ No anti-rust sealing, prone to corrosion and jamming in humid/rainy conditions |
