120 kW / 185 kW Electric Motor + 2-Speed AMT E-Powertrain for Bus & Truck

This 120 kW / 185 kW electric motor with a 2-speed AMT offers a cost-effective and versatile e-powertrain solution for city buses from 12 meters to 13 meters, highway coaches from 10 meters to 12 meters, and electric trucks from 12 tons to 18 tons.

The system features a lightweight design, weighing about 30-40% less than comparable direct-drive products. This weight reduction not only enhances vehicle efficiency but also supports higher payload capacity.

The motor and transmission are designed as an integrated unit, which helps reduce both motor and controller costs. The system also eliminates the need for costly transmission matching, further lowering the overall drivetrain cost.

3. Solution Features

The e-powertrain assembly features the AMT rated for over 2 million gear shifts and a design lifespan exceeding 8 years or 1 million kilometers. The AMT is precisely calibrated with the motor in an integrated configuration and features a PTO. This design ensures short shift intervals and smoother, more consistent power delivery.

Lightweight aluminum-alloy design: Approximately 30-40% lighter than comparable direct-drive systems, enhancing vehicle efficiency and performance.
2-speed pure electric system: Optimizes the motor's operating point through gear shifting, improving overall efficiency and reducing energy consumption by 3-5% compared to similar products under combined operating conditions.
High torque & strong gradeability: Delivers up to 3380 N.m of peak output torque, enabling powerful performance for heavy-duty applications. Achieves a maximum gradeability of over 25% under full load, ensuring strong climbing capability and reliable operation on steep terrains.

4. How Do We Ensure the Reliability of the AMT?

To maximize transmission reliability, our 2-speed AMT, specifically designed for pure electric vehicles, undergoes a comprehensive series of environmental and durability tests. Through these interative tests and optimizations, our pure electric AMT achieves a service life exceeding 1 million kilometers, delivering reliability comparable to direct-drive systems.

Environmental testing: waterproof, dustproof, high/low temperature, salt spray, and vibration tests.
Torque endurance: static torque tests exceeding 3x the rated torque.
Durability testing: rigorous comprehensive endurance tests, including over 1 million shift cycles per gear.
Bench simulation: over 200,000 km of chassis dynamometer testing simulating real vehicle operation.
Real-world road testing: more than 50,000 km of on-road trials.
Consistency verification: full-vehicle consistency tests across 50 assembled units.
