出租汽车计价器使用误差检定中影响轮胎修正值的因素有汽车载重,轮胎的型号、气压、花纹、新旧程度及摩擦等。例如,当汽车载重增加时,轮胎的变形增大。在路面上和在检定装置滚轮上的变形不同,路面上的变形较小,检定装置滚轮上的变形较大,从而引起车轮实际半径R的变化不同,增载后的A/B值变小,轮胎修正值C变小(绝对值增大,其值为负)。当轮胎新旧程度不同时,旧轮胎摩擦程度大,相 Taximeter use error correction test the value of tire correction factors include vehicle load, tire type, pressure, pattern, the level of old and friction and so on. For example, tire deformation increases as vehicle load increases. On the road surface and the deformation of the roller in the test device is different from the deformation of the road surface smaller, larger deflection on the test device wheel, resulting in the actual wheel radius R changes in different loading A / B value becomes smaller, The tire correction value C becomes smaller (absolute value increases, its value is negative). When the tire new and old different levels, the old tire friction degree, phase
