The evolution of electric commercial vehicle chassis is moving toward higher integration, smarter control and safer performance. TRION INDUSTRIAL officially launches a brand-new distributed drive + distributed electromechanical brake (EMB) system, tailored for heavy-duty electric trucks. This innovative electric truck axle solution has completed full bench validation, setting a new benchmark for safety, efficiency and reliability in the electric drive axle for truck sector.
Core Specifications of TRION Distributed Drive Axle
As a highly integrated distributed drive axle, this product delivers extraordinary power performance to meet the full-scenario demand of 49-ton heavy-duty trunk logistics trucks:
Peak power of the drive axle: 360kW (2×180kW)
Peak output torque of the drive axle: 51480Nm (2×25740Nm)
Matching EMB electromechanical brake: Maximum braking torque 22000Nm
This electric vehicle rear axle abandons the traditional transmission structure, realizing direct power output at the wheel end, which greatly improves transmission efficiency and chassis space utilization.
Rigorous Bench Test Validation for EMB Distributed Braking
TRION has carried out comprehensive and extreme bench tests on the EMB actuator to ensure long-term reliability under heavy-duty working conditions:
2 million full-stroke brake reliability tests: The EMB actuator maintains stable performance after 2 million full-stroke operations, meeting the long-cycle operation requirements of commercial vehicles.
30g high-intensity vibration test: In accordance with commercial vehicle non-elastic body vibration test standards, the system passes vibration tests up to 30g, adapting to harsh road conditions such as mining areas and construction sites.
Ultra-high thermal stability control: When the brake disc temperature reaches 370℃+ during continuous braking, the EMB unit remains at around 40℃, effectively avoiding thermal decay and ensuring braking stability.
Full-condition performance testing: Complete braking performance, response speed, continuous braking and other multi-scenario tests to ensure all-weather stable operation.
Industry-Leading Safety Performance: 10m Shorter Emergency Braking Distance
Compared with the traditional ABS + air brake system, TRION distributed drive + EMB solution shows obvious advantages in braking efficiency. Taking a 49-ton heavy-duty trunk logistics truck as an example:
When braking at an initial speed of 100km/h, the emergency braking distance is shortened by about 10m, greatly improving driving safety.
In addition, the system has successfully passed IESS (electronic body stability), EASR (E-Acceleration Slip Regulation) and ABS (anti-lock braking system) performance tests, realizing full-dimensional active safety protection for heavy-duty electric trucks.
Technical Value of TRION Distributed Drive + EMB Solution
This innovative truck drive axle solution breaks the limitations of traditional chassis design:
Higher transmission efficiency: The distributed drive structure eliminates intermediate transmission loss, making full use of motor power.
Safer braking response: EMB electromechanical brake has faster response speed than air brake, with shorter braking distance and higher stability.
Better durability: Ultra-long bench test verification ensures the system's service life and reduces later maintenance costs.
Smarter control: Integrated with electronic stability and anti-skid systems, it lays a foundation for intelligent driving of electric trucks.
Conclusion
TRION INDUSTRIAL's distributed drive + EMB distributed braking system represents the future development direction of electric drive axle truck technology. With leading power performance, extreme reliability and industry-leading safety advantages, it provides a core chassis solution for the upgrading of heavy-duty electric commercial vehicles, helping the high-quality development of the new energy commercial vehicle industry.
