一、影响机动车检测结果的因素1.滚筒表面附着系数JJG906-2009《滚筒反力式制动检验台检定规程》规定:滚筒表面当量附着系数≥0.70。由于不同生产厂家生产的制动试验台滚筒表面的附着系数各不相同,即使是同一制动台新、旧滚筒的附着系数也不同,不同的附着系数对机动车检测结果有直接影响。试验表明附着系数越大,制动试验台测力能力也越大,测出的制动力效果也越好。目前,国内制造的滚筒反力
First, the factors that affect the test results of motor vehicles 1. Roller surface adhesion coefficient JJG906-2009 “drum reaction force brake test station verification procedures” provides: drum surface equivalent adhesion coefficient ≥ 0.70. Because different manufacturers have different adhesion coefficients on the drum surface of the brake test stand, the adhesion coefficient of the old drum is different even for the same brake pad, and the different adhesion coefficients have a direct impact on the test results of the motor vehicle. The test shows that the greater the adhesion coefficient, the greater the capacity of the brake test stand for measuring force and the better the measured braking force. At present, the drum made in China is reactionary
