The Development of a Multi-Axle All-Terrain Vehicle with a Hydrostatic Transmission

This article considers the relevance of developing a multifunctional all-terrain vehicle with hydrostatic transmission. All-terrain 8?8 vehicles are presented. An analysis of the parameters is performed (engine power, specific power, load capacity, average pressure on the ground and fully loaded weight), and the rational parameters for a future vehicle design are selected. Examples of multi-axle vehicles with continuously variable electro-mechanical and hydrostatic transmissions are given. These transmissions are able to provide an individual adjustment actuator for each wheel and allow the vehicles to realize the maximum adhesion capabilities. Basic formulas for the calculation of hydrostatic transmission parameters are presented. Examples of the obtained dynamic characteristics are given. Based on the results of the numerical simulation, the authors analyze the operational efficiency and fuel consumption of the multifunctional all-terrain vehicle for various control laws of the hydrostatic transmission driveline. The data indicates that the relative increase of movement efficiency can reach 10%, and the relative decrease in the fuel consumption can reach 18% when the hydrostatic transmission control system with different control algorithms is used to operate the vehicle on terrain.
