四轮驱动拖拉机转差率计算方法的研究

Study of Computing Method of Four-wheel Drive Tractor Slip Ratio

介绍了国内外常用的两种四轮驱动拖拉机转差率的计算方法。目前国内常见的方法是基于通过经验值得出的动力半径来计算转差率,欧洲常见的方法是基于轮胎滚动周长,通过实地测量或制造商提供的数据计算转差率,并对两种计算方法进行了对比和分析。

The two common computing methods are introduced for four-wheel drive tractor slip ratio at home and abroad. At present, the common method in China is that the dynamic diameter obtained from empirical value is used to calculate the slip ratio. The common method in Europe is that the slip ratio is calculated based on tire rolling circumference, which is provided from field measurement or manufacturer. And then the comparison between these two methods is carried out.
