The key components of the chassis, such as the longitudinal beams, cross beams and connecting brackets, are all made of high-strength steel or carbon fiber composite materials, ensuring that they are not prone to deformation or fracture when subjected to huge impact forces and torsional forces. The application of these materials enhances the overall rigidity and corrosion resistance of the chassis, enabling it to adapt to harsh off-road environments and long-term high-intensity use, and ensuring the reliability and durability of the vehicle.
