Centralized Electric Drive Axle Solution for Trucks
As truck electrification moves beyond pilot projects and into large-scale production, OEMs and EV builders are increasingly focused on production-proven electric drive axle solutions that offer reliable performance, predictable costs, and long-term durability. Our electric drive axle solution for trucks is built on platforms that have already entered SOP and mass deployment, supporting 4.5-ton to 49-ton light-, medium-, and heavy-duty truck applications.
Based on a centralized, highly integrated e-axle architecture, this solution delivers high reliability and stability under demanding operating conditions. Designed with an emphasis on system integration and lightweight optimization, it improves overall drivetrain efficiency while giving OEMs the flexibility to adapt the system across different truck platforms and use cases.

Electric Truck Powertrain Architecture Considerations
Conventional Motor + Transmission + Axle
Typically considered when:
- Proven mechanical layouts and long-term durability are prioritized
- Existing chassis and driveline architecture are retained
- Fast deployment with minimal system redesign is required
Key characteristics:
- Mature and easy to implement
- Lower integration, limited regenerative braking efficiency
Integrated Centralized Electric Drive Axle
Typically considered when:
- System-level integration and efficiency are prioritized
- Packaging simplicity and battery space optimization are critical
- OEMs target scalable electric platforms for series production
Key characteristics:
- High integration of motor, transmission, and axle
- Simplified drivetrain layout with improved energy efficiency
When to Choose a Centralized Electric Drive Axle Solution
Centralized electric truck axles are a strong choice when the operating profile and platform objectives align with the following conditions. If your project matches most of the criteria below, this architecture is typically a rational and low-risk option.
Resource Transportation (Aggregates, Coal, Ore)
A centralized electric drive axle is a good fit when:
- Operating routes are predictable and combine loading yards with regional roads, highways, or expressways
- Uneven road conditions are localized, without sustained deep ruts or extreme ground clearance risks
- The project targets a balanced trade-off between acquisition cost, efficiency, and durability
Key decision signals:
- Ground clearance should be >260 mm at axle level
- PTO integration is needed for tipping or hydraulic systems
- Multi-speed gearbox (3-4 speeds) is required to cover start-up, gradients, and cruising
Express & Line-Haul Logistics
A centralized electric drive axle is a good fit when:
- Vehicles operate primarily on highways with stable road conditions and limited surface variability
- Annual mileage is high, making energy efficiency a primary cost driver
- Duty cycles are consistent, with limited extreme-grade requirements
Key decision signals:
- Energy consumption per kilometer is a critical KPI
- 2-speed transmission is sufficient due to limited steep climbing
- Lightweight drivetrain design supports efficiency-focused operation
