Description:
The NX series tractor adopts extended front two-leaf springs with newly calibrated suspension stiffness for better matching performance.
The rear suspension applies four-leaf springs with main and auxiliary spring combined structure. It optimizes suspension frequency under both empty and full load states, effectively avoiding resonance and greatly boosting riding comfort. This front 2-leaf plus rear 4-leaf spring layout realizes vehicle lightweight design, cutting overall weight by more than 70 kilograms.
HOWO tractor units are fitted with multiple mature and reliable engines, covering power outputs from 371 HP to 430 HP. The sturdy and durable chassis lowers maintenance and repair frequency even in harsh working environments, helping operators raise economic benefits.
The optimized drive axle reduces rotational speed at rated running speed, effectively lessening component wear. Its excellent transmission efficiency brings stronger running performance and lower fuel consumption.
