摘 要:文章主要研究车门玻璃与导槽安装配合偏差对玻璃升降的影响。考虑玻璃与导槽在Y向的配合偏差,建立玻璃升降轨迹方程和导槽模型,推导出玻璃在升降过程中,玻璃中线距导槽中线的Y向偏移量,进而得到玻璃受到的导槽密封条挤压力公式及升降摩擦力。并在此基础上,以某车型为例子,计算玻璃与导槽出现Y向配合偏差后,玻璃在上升过程中,玻璃受到的导槽密封条的挤压力以及摩擦阻力,并分析对玻璃升降的影响。关键词:配合偏差;Y向偏移量;挤压合力;上升阻力中图分类号:U463.8 文献标识码:B 文章编号:1671-7988(2019)01-49-04

Abstract: The paper investigates the effect of assembly deviation between door glass and guide on lifting of glass. Consider -ing the assembly deviation between door glass and guide in Y direction, the motion equation of door glass and the mathema -tical model of the guide is established respectively, and then the offset in Y direction between the two is obtained during lifting and dropping of glass at any point, furthermore, the formula of resultant force of the whole door glass pressed by guide sealing strip is derived. Finally, The curve of resultant force and lifting resistance of door glass caused by guide sealing strip is simulated and the effect on lifting is analyzed by taking one car for example.Keywords: Assembly Deviation; Offset in Y Direction; the Resultant Force; Lifting ResistanceCLC NO.: U463.8 Document Code: B Article ID: 1671-7988(2019)01-49-04
前言
車门玻璃升降困难、升降慢、升降卡滞是市场反馈较多的问题。玻璃升降系统是一个较复杂的系统,主要包括玻璃升降器、车门玻璃、导槽、导槽密封条、车门。影响玻璃升降顺畅因素多,各零件的安装配合偏差是较关键的因素之一[1-4]。玻璃在升降过程中,玻璃沿着导槽运行,导槽密封条唇边压缩变形对玻璃两侧产生压力,见图1所示。理想情况下,玻璃运行轨迹与导槽弧度一致,玻璃Y向两侧受到的导槽密封条内外唇边压缩合力为零,玻璃只受到重力和导槽密封条的摩擦力。
当玻璃与导槽配合存在偏差时,玻璃运行轨迹与导槽弧度不一致,见图2,导槽密封条两侧唇边变形压缩量不同,会造成玻璃Y向两侧受到的压缩合力不为零,玻璃受到额外的压力,并且两侧阻力不同,影响正常升降[5]。本文定量化分析了车门玻璃与导槽配合出现偏差,玻璃运行轨迹与导槽中线的偏移量及玻璃受到导槽密封条的挤压力和摩擦阻力,并分析对玻璃升降的影响。……
