制动力分配区域测试规程,针对卡车及巴士

[中文适用范围]： 本 SAE 推荐实践提供了现场测试程序和说明：仪器仪表和设备； b.车辆准备； C。空气制动单体和组合车辆的试验； d.制动力分配的计算；和 e。该测试程序旨在用作现场程序。如果需要使用实验室设备的更精细的方法，请参阅 SAE J1505。此程序提供了一种确定 GVWR 大于 4536 千克（10 000 磅）的卡车和公共汽车的制动力分配（制动系统有效性）的方法。 [外文原描述]： This SAE Recommended Practice provides a field test procedure and instructions for air braked single unit trucks, buses, and combination vehicles. Brake force distribution field testing with systems post-reduce stopping distance changes is still appropriate, however, vehicles with electronically controlled braking systems are not covered in this document and may need to be addressed in the future. It also provides recommendations for:aInstrumentation and equipment.bVehicle preparation.cTest of air-braked single and combination vehicles.dCalculation of brake force distribution.eThis test procedure is intended to be used as a field procedure. If a more refined method, utilizing laboratory equipment, is required, refer to SAE J1505.Cross Reference: J1505_202210,J1626
