TRION Industrial has launched a distributed drive axle system integrating dual motor propulsion and electromechanical braking, developed for heavy duty electric truck applications.
The system delivers a combined peak power of 360 kW and peak torque of 51,480 Nm through a dual motor configuration. By eliminating the conventional transmission layout and enabling direct drive at the wheel end, the design improves transmission efficiency and optimizes chassis space.
The integrated electromechanical braking system provides up to 22,000 Nm braking torque and supports faster response compared to conventional air brake systems. In testing with a 49 ton truck at 100 km per hour, emergency braking distance was reduced by approximately 10 meters.
Validation testing included 2 million full stroke brake cycles, vibration resistance up to 30 g, and thermal performance under brake disc temperatures exceeding 370°C. The braking unit maintained stable operating conditions during continuous load scenarios.
The system also integrates electronic stability and traction control functions, including ABS and slip regulation, supporting active safety performance in heavy duty vehicle operation.
The development reflects a shift toward integrated electric axle architectures combining propulsion, braking, and control systems within a single platform.
