FIELD: mining machines.
SUBSTANCE: invention relates to mining machines. The electromechanical transmission of a dump truck contains a traction generator connected to an internal combustion engine, two capacitor units, asynchronous motors of the left and right wheel motors, two electric braking units, two current sensors and two DC voltage sensors, two angular speed sensors, two connected to each other CAN bus. Each bus is connected to a yaw rate sensor, an inverter, a DC voltage sensor and a current sensor, a control unit connected to both CAN buses and a high-level controller that is connected to an internal combustion engine controller, a voltage regulator. Additionally, a limiting unit, a second voltage regulator and two measuring transducers of the amplitude value of an alternating voltage are introduced, connected to the generator windings and to the second voltage regulator. The control input of the limiting unit is connected to the output of the control unit.
EFFECT: quality of regulation in the electric drive system is improved.
