乘用车和轻型卡车轮用螺母座强度试验方法和性能要求

[中文适用范围]： 本SAE推荐实践提供了评估乘用车和轻型卡车（除双轮外，双轮由SAE J1965涵盖）和多用途乘用车售后市场紧固系统的统一程序和性能要求。紧固系统包括车轮、车轮螺栓和车轮螺母，以及车辆配合面。提供了基于可用信息的钢和铝配合面的摩擦系数。设计和验证车轮附件时，必须考虑许多因素。当该程序用于原始设备应用时，车辆制造商的规格优先于本文件中提到的规格。 [外文原描述]： This SAE Recommended Practice provides a uniform procedure and performance requirements for evaluating fastening systems for normal highway use on aftermarket passenger cars and light trucks (except dual wheels, which are covered by SAE J1965) and multipurpose passenger vehicles. The fastening system includes the wheel, wheel bolts, and wheel nuts, as well as vehicle mating surface. The coefficients of friction for steel and aluminum mating surfaces are provided based on information available. Many factors must be considered in design and validation of wheel attachments for each specific vehicle. Where the procedure is used for original equipment applications the vehicle manufacturers specifications supersede those noted.Cross Reference: J1102_201304,J1965_201503,J2283_201210
