In the article, the task of expanding the range of work in speed and moment of traction electric drive of an agricultural tractor is considered. We propose to achieve this goal through the use of a two-stage gearbox based on a three-row planetary gear. It is proposed to shift gear ratio by eliminating one row of the gearbox from the process of converting mechanical energy. Evaluation of the effect of the proposed solution was tested on a refined mathematical model, in which the electric drive is presented as a complex “frequency converter with vector control - motor - working body. The obtained simulation results allow us to argue that with the correct operation of the system in long-term operation, energy savings of up to 12% can be achieved (for various types of soil and operating modes: arable land, driving), and for transient processes - 7-8%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
