Research transmission’s operating modes of the medium-duty cargo vehicle

Abstract

The article presents the results of a study of transmission modes of the GAZon Next medium-duty cargo vehicle. The main goal of the presented scientific work is to obtain empirical data describing the operating modes of the engine and mechanical transmission in operational conditions. Engineers and programmers in the design of the kit, which includes automatic clutch and gearshift control mechanisms, as well as an electronic control unit for them, will use the obtained experimental correlations. Specialists of technical university have developed a measuring system that allows recording in time such parameters as: vehicle speed, acceleration, trajectory, engine operation parameters, loads that occur in the transmission and its drive, as well as the driver’s actions. This article provides a detailed description of the process of preparing vehicle components for research, as well as the installation of a measuring complex. The vehicle was tested at full weight, half of the maximum load and in curb weight to obtain more statistics on the operation of the transmission. In conclusion, the article presents the obtained experimental graphs.
