Abstract

The dynamic turning process of tracked vehicle is the transition turning process. The hydro-mechanical differential turning system is the new turning system of tracked vehicle using hydro-mechanical stepless transmission theory and being made up of hydraulic transmission and gear transmission. The hydro-mechanical differential turning theory is analyzed. Basing on turning dynamics and kinematics of tracked vehicle, the simulated model of hydro-mechanical differential dynamic turning process of tracked vehicle is established. The variety trend of turning angular velocity and turning radius with displacement ratio of hydraulic turning close loop system and transmission ratio of transmission case is obtained in this paper. The simulated results can be used to design the steering system of tracked vehicle.
