drawbar pull

The results show that when increasing the wheel load, drawbar pull accordingly increase and the tractive efficiency show downtrend before uptrend.

随着轮齿高度的增加，挂钩牵引力会随之增大，车轮的最大牵引效率有所降低；

When the drive slip is less than 0.05~ 0.30 percent, the drawbar pull in earth-moving machinery is good.

滑转率在0.05～0.30时，可使土方机械的驱动力达到最佳。

Drawbar pull-weight ratio

牵引杆拉力-重量比

The increase of lug height may result in the improvement of drawbar pull and driving efficiency.

增加齿高可以提高牵引力和驱动效率。

The predicting formula of the drawbar pull of driven wheels running on the sand is obtained by model test.

通过模拟试验，得出了驱动轮在砂地上行驶时的挂钩牵引力预测公式。

The maximum drawbar pull in earthmoving machinery is the one of main parameters in design and it is limited by the drive slip.

最大牵引力是土方机械设计的主要参数之一，其取决于对土方机械行走系统的滑转率的控制。
