Abstract:

The article presents the types of rational working torque characteristics of the engine ensuring its operation in economy mode. We have given a brief description of the test track, with the results of motion simulation of a military tracked vehicle used to select the operating characteristics of the moment. The basic factor for choosing the working torque characteristics is fuel consumption while driving on the track. The paper reveals the results of calculating the movement of the military tracked vehicle with the electromechanical transmission on the test track for four types of working torque characteristics of the engine and substantiates the most suitable option. The main results of calculating the operating modes and loading of motor transmission compartment units through the operation of the military tracked vehicle in four average conditions are presented. The calculation is made for the military tracked vehicles with electromechanical transmission and with manual transmission. Comparison of the calculation results shows the significant advantage of the electromechanical transmission over the mechanical transmission in terms of mobility and fuel efficiency in different operating conditions.
