Chassis vehicle technology evolution

Early chassis used riveting to connect longitudinal and transverse beams, but modern manufacturing technology has shifted to robotically welded, integral frames. Faraday's independently developed off-road chassis breaks with traditional design, combining a reinforced I-beam with a suspension system to maintain stability on unpaved roads. The braking system has been upgraded from a mechanical cable-operated system to an electronically controlled air suspension, enabling automatic load adjustment. Regarding industry standards, ISO 668:2020 specifies the fit tolerances between container chassis and container corner fittings, requiring a locking device with a tensile strength of at least 150 kN. The US AAR M-943 standard focuses on the wheelbase and roadworthiness of chassis used in rail transshipment applications.
