商用挂车和半挂车备用轮中心立轴的性能

[中文适用范围]： 本 SAE 推荐实践的目的是为按照 SAE 规范制造的主销及其支撑结构建立测试程序和最低性能标准。 SAE J 700 中所示的尺寸将允许在安装条件下建立标准间隙，这反过来又允许第五轮制造商设计其产品，以与根据 SAE 规范制造和安装的任何主销建立互换性。 [外文原描述]： The purpose of this SAE Recommended Practice is to establish test procedures and minimum performance StandardDetails for kingpins and their supporting structure manufactured to SAE specifications. The dimensions shown in SAE J700 will permit the establishment of standard clearances in the installed condition which, in turn, will permit fifth wheel manufacturers to design their products to establish interchangeability with any kingpin made and installed to the SAE specification.Cross Reference: J700_202011
