Eaton has launched the EV Truetrac differential, a new helical-gear limited-slip differential designed specifically for electric vehicles (EVs), addressing the unique challenges of EV propulsion systems.
Key Innovations:
- Low-Viscosity Oil Compatibility: Redesigned with micro-geometry tuning for durability in EVs’ water-like oils, which are shared with the motor system.
- Noise Reduction (NVH): Refined gear design minimizes noise, crucial for EVs lacking engine noise to mask drivetrain sounds.
- High Torque Durability: Engineered to handle EVs’ instant high torque delivery while maintaining seamless traction control.
- Material Upgrades: Advanced materials ensure longevity and performance in high-stress, high-torque environments.
Market Focus:
- Targets pickup trucks and SUVs for daily driving, off-roading, and towing.
- Offers a passive, automatic traction solution, unlike Eaton’s electronically controlled ELockers.
- Meeting rising demand in North America and Asia for rugged EV drivetrain components.
The goal of Eaton’s EV Truetrac is to bring proven traction tech into the electric era, tailored for the quiet, high-torque, and efficiency-driven demands of modern EVs.
