Product Code:SAE J667 Title:Brake Test Code--Inertia Dynamometer (Cancelled Feb 2002) Issuing Committee:Brake Dynamometer Standards Committee Scope: This SAE Recommended Practice establishes a uniform laboratory procedure for evaluating performance and wear of automotive brakes and brake drums by an inertial dynamometer simulation of vehicle test and operating conditions. The code is applicable to hydraulic, air, or electrically actuated brakes. For electric brakes, 'ampere' values are substituted for 'line pressure' where specified in the procedure or on data and curve sheets. The procedure includes the following tests: 1. Torque output and deceleration (various speeds and brake input). 2. Evaluation of lining life (wear tests). 3. Brake characteristics (fade and recovery tests, noise, chatter, grabbiness). 4. Drum evaluation (wear, heat checking, scoring).【英文标准名称】:DrivingComponents;FlangedBearings,Fastenedwith4Screws 【原文标准名称】:传动元件.用四个螺钉紧固的法兰轴承 【标准号】:DIN503-1946 【标准状态】:作废 【国别】: 【发布日期】: 【实施或试行日期】: 【发布单位】:德国标准化学会(DE-DIN) 【起草单位】: 【标准类型】:() 【标准水平】:() 【中文主题词】: 【英文主题词】: 【摘要】: 【中国标准分类号】: 【国际标准分类号】: 【页数】: 【正文语种】:
