E Axle for Tram: Powering Efficient and Reliable Rubber-Tire Metros
For urban transit systems, especially rubber-tire virtual rail metros, the choice of propulsion system defines operational success. An electric drive axle - integrating the motor, transmission, braking, and steering into a unified unit - reimagines how trams deliver power, efficiency, and adaptability. Unlike traditional drivetrains relying on separate components, our e axle for tram (model EA1100K) is engineered to meet the unique demands of modern public transport: tight turning radii, frequent stops, and strict emission standards. Let's explore how this system transforms performance for operators and passengers alike.
Electric motors
Permanent magnet synchronous motors, or PMSMs
Reduction gearing
To match motor speed to wheel speed
Power electronics
For motor control and energy management
Sensors
For torque, temperature, and fault monitoring
Tram e axles solve unique challenges for rubber-tired metros through four core strengths:
01
±18° Steering Flexibility
The EA1100K's integrated steering system allows trams to weave through tight urban spaces, eliminating the need for wide turning radii.
02
Dual-Motor Power (2×90 kW, 2×350 N·m)
The electric motor with axle design delivers consistent torque for smooth starts/stops, even with heavy passenger loads.
03
IP67 Protection for Urban Durability
Rated IP67, the axle resists water, dust, and debris-vital for trams operating in all weather conditions.
04
Low-Floor Accessibility via Portal Design
The portal layout (motor above the wheel) enables low-floor trams, enhancing accessibility for passengers with mobility needs.

FAQ: Your Tram E Axle Questions Answered
Q1: Can the e axle for tram handle tight turns at high speeds?
The EA1100K is optimized for urban speeds (≤50 km/h). At higher speeds, the steering system stabilizes automatically to prevent instability.
Q2: How does IP67 protection benefit tram operations?
IP67 resists dust and temporary water immersion (e.g., puddles), reducing downtime from environmental damage.
Q3: Is the e axle system compatible with different tram designs?
Yes. We customize e axle components (torque, steering angle, voltage) for larger/smaller trams.
Q4: How does the electric motor with axle improve energy efficiency?
Regenerative braking captures energy during stops, reducing consumption by up to 20% vs. non-regenerative systems.
