Distributed Electric Drive Axle For Heavy Duty Truck

EA5000N

User value

Safety

Core strategy

Through distributed drive electronic differential control, it has the safety configuration of EASR (Electronic Acceleration Slip Regulation) and IESS (Intelligent Electronic Stability System), which reduces vehicle energy consumption and improves vehicle safety and handling stability under extreme working conditions. Electronic Differential lock can effectively achieve road escape.

Placement battery at the bottom of the vehicle to lower the center of gravity

Sufficient space is provided for the bottom layout of the battery, and the center of gravity of the battery is lowered by 1620mm, improving the roll stability of the vehicle.

Power does not interrupt when shifting gears

Dual-motor structure, combined with advanced shift control strategy, ensures no power interruption during shifting, making the vehicle safer and more comfortable to drive.

Economy

Maximum transmission efficiency increased by 4%

The transmission system has a simple structure and a short drive chain, and the maximum transmission efficiency of the system is increased by 4%.

Energy feedback increased by 100%

The forward and reverse torques of the gears are exactly the same, which improves the energy feedback efficiency and increases the driving mileage.

Reduced tire wear

The wheel motor electronic differential system reduces tire wear and reduces transportation costs.

Dynamic

The axle torque 51480N.m

The maximum output torque of the axle is 51480N.m, and the maximum motor feedback torque can also reach 51480N.m. It can reduce braking heat decay during downhill, so there is no need to add a water tank to cool the brakes.

Lightweight

Lose weight at least 300KG

The single axle weighs 920kg. For a 4×2 tractor, the distributed drive system is 462kg lighter than the direct drive system and 300kg lighter than the integrated axle system, increasing payload.

Compatible models

Heavy Duty Truck：8×4/6×4 Tractor, mixer truck, 18-ton sanitation truck

Coach：Intercity bus，tourist coach
