13T Wheel Side Motor Axle: A Reliable E Axle Solution for Urban Bus Electrification

As a professional EV parts manufacturer dedicated to commercial vehicle electrification, our 13T wheel side motor axle is a field-validated e axle system built exclusively for electric transit buses. Designed to match the demands of high-frequency urban operation, it delivers an ideal balance of power, durability and efficiency for 10.5–12m city buses and 18m articulated coaches.

Core Performance Specifications

Built with dual permanent magnet synchronous motors, this electric drive axle delivers 2×160kW of peak output power and 2×9290N·m of maximum torque, supporting a rated axle load of 13,000kg. With a 540V rated voltage system and 18.58 speed ratio, it is optimized for the stop-and-go driving cycles typical of urban bus routes, delivering responsive acceleration and reliable gradeability.

Built for Reliable Commercial Operation

Engineered for real-world transit conditions, the axle features IP67 ingress protection, ensuring stable performance even in rainy, dusty and harsh operating environments. It is equipped with ventilated disc brakes for consistent, safe braking performance under heavy passenger loads. The wheel-side integrated design eliminates the traditional central drive shaft, reducing overall axle weight to 1070kg while freeing up valuable chassis space.

Ideal Application Scenarios

This 13T electric bus axle is perfectly suited for 10.5–12m city buses and 18m articulated buses, the mainstream models of urban public transport systems. Its compact structure supports full low-floor bus layouts, improving passenger accessibility and allowing more flexible battery packaging to extend driving range.

As a mature e axle systems solution validated by millions of kilometers of commercial operation, it helps bus OEMs and fleet operators accelerate electrification projects with lower R&D risk and reliable long-term performance.
