Relationship between steering power ratio and turning coefficient of tracked vehicle adopting differential steering mechanism

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.
