货车和客车制动力分布试验程序

[中文适用范围]： 本 SAE 推荐做法提供了空气制动单体卡车、公共汽车和组合车辆的测试程序和说明。它还提供了以下方面的建议：仪表和设备、车辆准备以及制动力分配的计算。此程序提供了一种方法来确定 GVWR 大于 4536 千克（10 000 磅）的卡车和公共汽车的制动力分配和阈值压力。其他设备和程序可用于确定车辆制动器吸收的近似相对功或能量。 A.“基于性能的制动测试仪”可以测定不同制动器的低压/低速扭矩。 “温度/热平衡”可以显示制动器的相对温度，从而指示吸收的大致能量。 [外文原描述]： This SAE Recommended Practice provides the test procedure and instructions for air braked single unit trucks, buses, and combination vehicles. Brake force distribution testing with systems post-reduced stopping distance changes is still appropriate; however, vehicles with electrononically 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.cCalculating distribution of brake force.Cross Reference: J1626,J1854_201309
