The article proves that the use of automobile trains, in comparison with single automobiles, allows to increase productivity and reduce the cost of automobile transportation. The use of an active trailed link allows to increase the dynamic properties of automobile trains. In addition, the use of an active trailed link makes it possible to increase the energy efficiency of automobile trains by increasing the efficiency of the wheel drive. It was established that increasing the efficiency of the wheel drive is possible due to the rational distribution of torque (traction moments) and power between the wheels of the tractor and the trailed link. According to the criterion of the maximum efficiency of the wheel drive, a method of determining the rational (optimal) distribution of traction moments and, accordingly, the power of the electric motors of the tractor and trailer (semi-trailer) is proposed. It was determined that the rational ratio of traction moments (power) is proportional to the ratio of the total circular stiffness of the tires of the tractor and trailer (semi-trailer). Various options for the distribution of traction moments (powers) for the combination of tractor vehicles and trailers (semi-trailers) with different combinations of the driving wheels number are considered. The presented results show that the ratio of the number of driving wheels of the tractor vehicle and the active trailed link has a significant influence on the choice of a rational ratio of traction moments on the specified links of road trains.
