Study on Transmission System Scheme of Electric Drive Tracked Vehicles

In order to improve the utilization rate of the motor power for electric drive tracked vehicles, based on the improved bilateral independent motor drive scheme,a driving scheme based on power cou-pling mechanism is proposed to make the steering regeneration power to flow back as much as possible in mechanical means.Models of kinematics and dynamics of the scheme are built,and the high speed side steering input and output powers are comparatively analyzed.Meanwhile,modeling simulation analysis by using RecurDyn is done to verify the feasibility of the transmission scheme of coupling mechanism.The results show that using the scheme can significantly reduce the power requirements of motor.
