【Abstract】 Hydro-mechanical differential turning integrates the excellent characteristics of hydraulic transmission and mechanical transmission, can realize stepless turning, reduce turning radius of tracked vehicles, and improve its mobility. In this paper, the steady state turning process of hydro-mechanical differential turning of tracked vehicles is analyzed, kinematic and dynamic models are established. According to the mathematical model, combined with Weichai WP13.550 engine and a type of tracked vehicle, the turning process is simulated and analyzed. Simulation and analysis results show that the matching parameters can meet the requirements of vehicle steering performance.更多还原
