Jurisprudence analysis: the carriage adopts high-strength cold plate, with special equipment and mold, which is light in weight and high in strength. At the same time, the car board is treated by pickling and phosphating, which improves the oil-gas adhesion and reduces the self-weight of the product. Door opening structure: automatic door opening structure, manual safety design, flexibility, simplicity, safety and reliability. Suspension system: adopt a unique new suspension system with high strength and strong impact resistance; The load of each axis is balanced, and the angle of the system pull rod is designed reasonably. In the process of frequent bumps, the instantaneous friction and sliding distance between the tire and the ground decrease, effectively reducing tire wear. At the same time, the adjustable pull rod can adjust the wheelbase, which can effectively avoid tire eccentric wear and gnawing. The shaft clamp is integrally cast, and the lower clamp is a patented product.
