Electric Trailer Axle

When selecting the right drivetrain for heavy-duty vehicles, reliability and efficiency come first. Our electric trailer axle is designed to support trucks and trailers that demand both high torque and long-lasting durability. By integrating dual permanent magnet synchronous motors (PMSM) directly into the axle, it provides consistent output while reducing the complexity of traditional driveline systems. For operators, this means smoother driving, safer handling, and optimized energy use.

With a rated load capacity of up to 16 tons and a maximum torque of 50,000 N·m, the electric trailer axle delivers the power needed for demanding road conditions while maintaining comfort and stability. Its compact integration also frees space for battery layout, making it practical for new energy vehicle platforms.

Our electric trailer axle incorporates multiple engineering features that align with the needs of today's transport industry. Dual-motor design allows uninterrupted gear shifting, supported by advanced electronic control systems. With IP68 protection, the axle is shielded against dust and water, making it dependable in diverse environments.

Another important aspect is the system output torque, which ensures trailers can manage heavy loads even on steep gradients. Wheel speeds of up to 6,200 r/min enable reliable highway operation, while optimized gear ratios provide efficient distribution of power across various driving conditions.

Operators looking at an electric trailer axle often prioritize three things: safety, efficiency, and maintenance cost. This axle delivers on all three. The integrated gear-shifting strategy ensures no loss of power during transitions, which makes the vehicle safer and more comfortable. Compared to central drive systems, it reduces overall vehicle weight by around 300 kg, directly increasing payload capacity.

Lower vehicle center of gravity also reduces the risk of rollover, improving stability when carrying heavy cargo. The electronic differential system extends tire mileage up to 100,000 km, significantly cutting operational expenses. In addition, its anti-slip driving function helps maintain traction in rain, snow, and other challenging conditions.

Our electric trailer axle is suitable for multiple vehicle configurations, including 4x2, 6x2, and 8x4 tractors. By supporting different load demands, it adapts well to logistics fleets, construction transport, and long-haul trailers. Its ability to handle both city routes and long-distance travel makes it an ideal choice for heavy-duty commercial operations that seek both performance and efficiency.

Every electric trailer axle undergoes rigorous research and testing before reaching the customer. Our R&D team focuses on integrating software-controlled electronic differential systems, ensuring optimized torque distribution. High-speed endurance tests, thermal simulations, and real-road validation all contribute to building a system that can withstand years of operation without performance loss.

We continuously refine motor design, gearbox ratios, and cooling systems, ensuring that the axle is ready for next-generation electric trucks and trailers. This ongoing development is not only about meeting current transport needs but also preparing for future efficiency and sustainability requirements.

Our manufacturing base in China is equipped with automated production lines, precision machining equipment, and advanced testing facilities. Every electric trailer axle is produced under strict quality standards to ensure consistent performance.

Traceability systems are applied across all stages, from raw material selection to final assembly. This allows each axle to meet the requirements of demanding heavy-duty fleets while maintaining the same high-quality level across all units. Customers can be confident that every product delivered matches the technical specifications promised.
