HDE4.5t

High reliability: 17 years of experience in the forward development of electric drive axles; 1.5 million km of vehicle road testing in extreme cold, extreme heat, high humidity, and high-altitude environments, Significantly reducing vehicle failure rates and after-sales maintenance frequency, while improving overall vehicle operational availability.

High efficiency: Enhanced electric drive efficiency, optimized gear parameters + surface modification, and precision grinding treatment to reduce mechanical friction and churning losses, increasing transmission efficiency by over 5%; Reducing vehicle energy consumption and improving operational economy.

Lightweight design: Integrated design minimizes redundant structures and connectors; high-strength, lightweight materials are extensively applied to housings, brackets, and other components. Curb weight reduced by 15–30 kg.

Extended maintenance-free intervals: No initial maintenance required, long oil-change intervals of 120,000/300,000 km for the main reducer, and lifetime maintenance-free wheel ends.
