“…The mining companies Rio Tinto in Australia and Codelco in Chile together with machine-building companies Komatsu (Japan) and Caterpillar (USA) have become the pioneers in the introduction of such technologies; in recent years, Hitachi, a manufacturer of dump trucks, has also joined them. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. The created samples of autonomous dump trucks are designed for transporting rock mass (overburden and minerals) in the conditions of open pit and open-cut mines with the use of unmanned technologies.…”

The article discusses the issues of feasibility study of R&D in the field of design and implementation of mining dump trucks with autonomous traffic control. A review of the current state of the world shows that the use of autonomous equipment in open-pit mining is acquiring industrial scale and developing at a rapid pace. Autonomous mining dump trucks have the following advantages: they can work 24/7, since such technology is deserted, make it possible to reduce the width of the roadway, provide an increase in the angle of ascent, and do not require a position for turning, increase productivity, and ensure the safety of mining operations.

“…When designing a dump truck (DT), the parameters and characteristics of the components of the hydraulic system (HS) are to be determined [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. The HS of a modern DT includes many elements, the characteristics of which are interrelated with each other.…”

At the initial stage of designing a dump truck it is necessary to determine the main units and assemblies of the vehicle, their parameters and dimensions. One of the systems of the dump truck is the hydraulic system. When creating new dump trucks, there is a necessity to define parameters and characteristics of hydraulic system components. The peculiarity of quarry dump trucks, in contrast to dump trucks, which are used on public roads, is that the modes of their operation are different. Therefore, when creating new dump trucks, it is necessary to develop an algorithm for selecting and justifying the parameters of the hydraulic system at the early stages of design. The article substantiates the necessity of developing an algorithm for determining the parameters of the hydraulic system. The main hydraulic consumers are defined and the requirements of each of the consumers are presented. The algorithm of justification of the parameters of the hydraulic system of the quarry dump truck is described. Determination of the required pump capacity of the hydraulic system is described. The use of the described algorithm for justification of the hydraulic system parameters of the dump truck contributes to the reduction of terms of development of design documentation at the early stages of design.

Traction battery vehicles (TBV) are currently gaining more and more popularity and are gradually replacing vehicles with ICE and traditional transmissions. The usage of an electric traction drive as part of TBV solves a number of problems that manufacturers of this type of equipment face today: reducing harmful emissions into the atmosphere, reducing noise, used lubricants recycling, and the increase of the energy efficiency. From the point of view of the scientific research, this type of wheeled vehicles is also of high interest due to the large number of problems and tasks that have formed at the moment. It is a common knowledge, that one of the main problematic issues for the TBV is a rather limited range. In cargo electric vehicles and buses, in order to reduce the size and increase the usable volume of the passenger compartment or cargo space, as well as to unify the products of the power unit and drive, there are used the transmissions, which are the combination of mechanical and electrical components with appropriate control systems. The mechanical component includes a gearbox with one or more gear ratios, an inter-wheel differential, axle shafts, bearings and other components. The electrical component is a traction motor located directly in the drive axle (integrated) or on the outside of the crankcase, as well as a voltage converter with a control system and the necessary switching elements. Similar implementations of the driving axles of vehicles with traction batteries are called mechatronic transmissions.
