Research of Shifting Quality of Dual Hydro-mechanical Transmission
Abstract
The hydro-mechanical transmission（ HMT） is obtained by connecting hydraulic transmission and mechanical transmission in parallel. It has the advantages of high torque of hydraulic transmission and high mechanical transmission efficiency. The dual hydro-mechanical transmission（ DHMT） is connected by two sets of double flow. The components of the DHMT system are modeled and the shifting control strategy of DHMT system is proposed based on the established dynamics model. The co-simulation model of DHMT is built based on AMEsim and Simulink. Finally,the simulation results are analyzed and the correctness of the shifting control strategy is verified.
