标准摘要
[中文适用范围]: 本SAE推荐规范为所有新的卡车、公共汽车和组合车辆(设计用于道路使用并符合以下分类)的制动系统结构完整性测试建立了一种方法: a. 卡车和公共汽车:超过4500公斤(10000磅)GVWR b. 组合车辆:牵引车辆超过4500公斤(10000磅)GVWR 测试包括两个不同的测试:结构耐久性测试和结构极限强度测试。 注:这两个测试源自不同的程序,并在此推荐规范中合并。每个测试都可以被视为对服务制动结构的独立评估。根据可用时间、成本限制、所需评估和可用历史数据,这些测试中的任何一个都可以被视为对制动结构的完整评估。 1.1 目的 本文件的主要目的是评估车辆制动系统的结构完整性。然而,测试过程中也可以评估其他区域,如转向或悬挂系统,前提是不以任何方式修改以下详细的标准和程序。为了可重复性,建议尽可能使用制动施加装置,因为它可以消除不同操作员在施加时间和力度上的变化。 [外文原描述]: This SAE Recommended Practice establishes a method of testing the structural integrity of the brake system of all new trucks, buses, and combination vehicles designed for roadway use and falling in the following classifications:aTruck and bus: Over 4500 kg (10000 pounds) GVWRbCombination vehicle: Towing vehicle over 4500 kg (10000 pounds) GVWRThe test consists of two distinct tests: a structural endurance test followed by a structural ultimate strength test.NOTE: These two tests originated from separate procedures, and were combined in this recommended practice. Each test can be considered to be an independent evaluation of the service brake’s structure. Based on time available, cost limitations, and the desired evaluation and historical data available, either of these tests could be considered as a complete evaluation of the brake’s structure.Cross Reference: FMVSS105,FMVSS121,J1404_201411,J1626
