Formation of technical requirements for mechatronic transmissions components of modern eco-friendly vehicles

Abstract

In electric modern energy efficient trucks and buses, transmissions with an electric motor and inverter located directly in the drive axle are increasingly used to increase the useful volume of the passenger compartment or cargo space and improve performance. This highly integrated electromechanical unit is called a mechatronic transmission. The procedure for forming technical requirements for the parameters and operating modes of traction electric motors is relevant and different from that of energy efficient trucks with traditional transmission in this case [1, 2]. Thus, the purpose of this study is to determine the requirements for different values of traction electric motor power as components of mechatronic transmission based on the analysis of the driving modes of vehicles with internal combustion engines and mechanical transmission. In the course of the work, a number of representative recorded cycles of movement of mainline modern energy efficient trucks of PJSC KAMAZ on the roads of the Russian Federation were studied and a synthesis of a generalized cycle with identical statistical characteristics was carried out. In addition, the article provides a comparative analysis of the formulated requirements with the parameters of similar samples of mechatronic transmissions from global manufacturers.
