摘要
为了研究采用动力差速转向机构的液压机械双流驱动系统履带车辆转向时的功率增长程度,该文对其载荷比和转向系数进行理论研究,并获得了两者之间的关系,与其他转向机构的载荷比-转向系数射线比较,分析了载荷比的增长情况。通过样机试验和计算获得了载荷比和转向系数的数值和关系,并绘制了载荷比-转向系数射线。载荷比与转向系数的关系可用来评价动力差速转向机构的转向性能。该文为进一步分析采用动力差速式转向机构的液压机械双流驱动系统的转向性能提供了参考。
In order to investigate engine power increases for tracked vehicle adopting differential steering mechanism in hydro-mechanical double-power driving system,the steering power ratio,turning coefficient and the relationship between them were theoretically studied.Compared with steering power ratio and turning coefficient radials（ξ-υ） of the other steering mechanisms,the power increasing rate was analyzed.The prototype was tested and the relationship between steering power ratio and turning coefficient was acquired through experiment and calculation.ξ-υ radials was acquired according to the experiment data.The turning performance of the differential steering mechanism was evaluated according to the study results.This research provides a reference for the advanced study on hydro-mechanical double-power driving system adopting differential steering mechanism for tracked vehicle.
