摘　　要：通过台架试验法试验研究检测汽车制动性能,提出举升式汽车加载制动检验台的安置角及转鼓中心距、安装与举升高度等关键技术参数的指标和技术要求。研究结果表明:转鼓中心距的设计计算以承载重量、车轮直径、安置角为基本依据,对应额定载荷为100、130 kN的转鼓制动台,转鼓中心距分别为450、470 mm,误差均为±10 mm;转鼓加载制动台安装时,转鼓上母线距地水平面高度应为40~45 mm,加载举升高度距地水平面不小于200 mm。该研究可为举升式汽车加载制动台的设计、生产、使用和产品检验提供参考。The automobile braking performance is tested by bench test,and the requirements for key parameters of the lift-mode vehicle load braking test bench including formed angle,roller central distance and height of install and lift,etc are proposed.The results indicate that the design of the roller central distance should be based on the load capacity,wheel diameter and formed angle.For the roller brake bench with rated load capacity of 100 N and 130 N,the roller central distance should be 450 mm and 470 mm with±10 mm error.When installing the bench,the suitable height from the ground to the auxiliary roller is 40-45 mm,and the loading lift height from the ground should be no less than 200 mm.The study can provide reference for the design,production,use and product ispection of lift-mode vehicle load braking test bench.
