摘要： 当前商用车底盘各总成虽已做防腐与耐候性设计，但在售前库存期或使用 1 年左右仍 出现不同程度锈蚀，常见于车架、板簧、底盘安装支架等处，严重影响整车安全性、可靠性、 使用寿命及外观。为提升底盘防腐性能，文章分析其锈蚀现状与原因，以某 18 t 平台 4×2 纯 电动洗扫车项目为基础，总结有效的防腐整改措施，阐述底盘关键总成的防腐方案及整车设 计层面的防腐性能提升方法，为商用车防腐性能研究提供参考。

Abstract: Although all assemblies of current commercial vehicle chassis are designed with anticorrosion and weather resistance, different degrees of rust still occur during pre-sales storage or after about one year of use, commonly on frames, leaf springs, chassis mounting brackets and other parts, which seriously affects the safety, reliability, service life and appearance of the whole vehicle. To improve the anti-corrosion performance of the chassis, this paper analyzes the current situation and causes of its rusting, summarizes effective anti-corrosion rectification measures based on a 18 t platform 4×2 pure electric road sweeper project, expounds the anti-corrosion schemes for key chassis assemblies and the methods to improve anti-corrosion performance from the perspective of vehicle design, and provides a reference for the research on anti-corrosion performance of commercial vehicles.
