Recently, domestic trailer parts manufacturers released new core components, including lightweight axles and high-strength suspension systems. The new components utilize high-strength aluminum alloy and wear-resistant steel, reducing axle weight by 20% compared to traditional products and increasing suspension system load capacity by 15%, making them compatible with various freight trailers. This batch of components underwent 18 months of research and development, completed 800,000 kilometers of real-vehicle testing, and passed certification from the National Automotive Quality Supervision and Inspection Center. Currently in mass production, they can help trailers reduce weight by over 300 kg and lower fuel consumption by 1.2 liters per 100 kilometers, helping logistics companies reduce costs and increase efficiency.
