The work presents the design of a traction electric equipment set of an electromechanical drivetrain (EMD) to be used with 300-hp-class agricultural wheeled tractors. Comparative characteristics of various drivetrain types used in agricultural tractors are presented; and the advantages of using EMDs in tractors are discussed. The EDM advantages are as follows: improved technical and economic parameters of the tractor; reduced dynamic loads on the tractor and diesel units; reduces wheel slippage; reduced fuel consumption (by up to 30%); continuous variation of speed of the tractor and aggregated implements; reduced expenses on maintenance, repair and spare parts; increased total reliability, controllability and comfort; possibility to use the tractor as a power source (optionally). Considered in combination, all these advantages clearly speak in favor of using electromechanical drivetrains.

An electro-hydraulic servo system makes the basis for a mechatronic locomotion module (LM) and for a complex comprising an LM and an undercarriage of a vehicle. The servo system of the wheel module/LM complex is a combination of the information and power channels of the electro-hydraulic wheel drive within the steering system. A combination of the servo systems makes up a complex of servo systems of the steering system of the multi axis wheel mover of the vehicle. Theoretical and experimental studies of the functioning all-wheel steering were aimed on substantiation the rational algorithmic maintenance of the automatic control system. The results of the study allowed formulating the basic principles of designing and calculating the functionality algorithms for the steering system of the complex of mechatronic modules of the multi-axis vehicle.
