Abstract: To address the bottleneck in lightweight design of the classical balanced suspension for heavy-duty trucks, this paper proposes an innovative balanced suspension design scheme. Focusing on this new suspension, the study analyzes its structural differences from the classical design, its functional mechanisms, its contribution to vehicle lightweighting, and assesses its economic benefits from the dual perspectives of manufacturers and users. Comparative analysis shows that the new balanced suspension demonstrates significant advantages in structural integration, system lightweighting, and economic efficiency. Empirical results indicate that applying this suspension system can achieve a weight reduction of 118 kg per vehicle, reduce production costs by 2 292 yuan, and generate an additional profit of 49 560 yuan for users over a six-year service cycle. In conclusion, this new balanced suspension holds broad prospects for application and promotion in the heavy-duty truck standard-load transportation sector.
