Abstract：A powertrain design based on planetary gear sets is developed to improve the transmission efficiency of hydraulic hybrid track-type vehicles. An automated modelling framework is built based on the planetary transmission characteristics to characterize the powertrain dynamics. Screening based on the physical property requirements limits the number of feasible designs. The straight driving and steering characteristics of these feasible designs are calculated to select the better designs compared with existing designs. Finally, a dynamic programming analysis of the typical driving cycle of track-type bull dozers is used to calculate the fuel economy. Simulations show that this powertrain gives better traction, steering performance and fuel economy than existing hydraulic track-type bull dozers.
