Electric Axle for Tram

1. Overview

Modern tram systems are evolving quickly as cities demand quieter, cleaner, and more reliable transportation. At the heart of this transition lies TRION electric axle for tram, a component that directly determines performance, passenger comfort, and long-term reliability. Instead of simply serving as a drivetrain, today’s electric axles are designed to integrate motor, gearing, and braking into a compact system that supports the needs of busy urban networks.

2. Product Introduction

TRION EA1100K model is a 9T steering electric portal axle engineered for modern trams that operate in dense urban corridors. It has been built with precision to manage both high torque delivery and smooth steering under frequent stop-and-go conditions. The axle combines dual PMSM (Permanent Magnet Synchronous Motors) with integrated braking and gear systems, ensuring that trams can handle daily service without compromising on efficiency.

With its rated axle load of 9,000 kg and peak torque of 2 × 350 Nm, the axle has proven itself in applications that require consistent power and responsive handling. The design also prioritizes serviceability, meaning operators can minimize downtime and keep fleets running with predictable maintenance schedules.

3. Core Components

Every electric axle for tram relies on its core elements to deliver real-world value:

• Dual PMSM Motors – Providing peak power of 2 × 90 kW and rated output of 2 × 55 kW, these motors allow for stable acceleration and hill-climbing ability, while their compact design supports underfloor integration.
• High-speed operation – With a maximum motor speed of 9500 r/min, trams benefit from efficient energy conversion and reduced vibration during operation.
• Air Disc Brake System – Safety remains central, and the air disc brake ensures reliable stopping power even in wet or variable conditions.
• Durable Gear Ratio (17.55) – Balances energy efficiency with power delivery, optimizing the overall traction system.

Each of these components has been selected not only for durability but also to fit seamlessly into tram designs, making the electric axle for tram a trusted solution for long-term operation.

4. Solution Features

Operators and vehicle manufacturers look for solutions that can stand up to daily operational demands. TRION EA1100K electric axle brings several features that directly respond to those needs:

• Compact structure that reduces installation complexity.
• IP67 protection level, ensuring dust and water resistance for long service life.
• Wide steering angle of ±18°, which improves maneuverability in narrow urban streets.
• Flexible tire compatibility (305/70R22.5, 385/65R22.5), allowing adaptability to different tram platforms.
• Energy efficiency, achieved through optimized gearing and motor control, lowering operating costs.

These advantages highlight why investing in a high-quality electric axle for tram is more than just a drivetrain choice—it’s about ensuring reliability and passenger satisfaction over years of service.

5. Product Applications

TRION EA1100K has been developed specifically for tram systems in cities and regional transport lines. It supports both new vehicle designs and modernization projects where existing fleets are upgraded with electric drivetrains. Whether operating in high-frequency downtown loops or longer suburban routes, the axle ensures stable performance across different duty cycles.

6. Research & Development

Behind the product is a dedicated R&D process that emphasizes simulation, bench testing, and road validation. Each electric axle for tram undergoes load testing to confirm torque consistency, endurance trials for more than 100,000 km equivalent mileage, and environmental checks to validate water and dust resistance. The result is a solution that aligns with international quality benchmarks and offers confidence to transport operators.

7. Manufacturing Excellence

Production of TRION EA1100K electric axle takes place in facilities equipped with automated machining, robotic welding, and digital quality inspection. Every axle is subjected to strict dimensional checks and dynamic performance testing before shipment. This manufacturing discipline ensures that the axle performs in real-world conditions exactly as designed.
