“…The current level of development of electric motors makes competitive options with a mechanical and electromechanical drive. In the latter case, the block concept of the drive, considered, for example, in [18], is of interest. However, in this case, the use of an interwheel controlled PDM is also implied.…”

“…Feedback is usually carried out according to the signals of the wheel speed sensors of the sides, or according to the signals from thermal accelerometers. In the Russian Federation, a number of technical solutions have been proposed to create alternative kinematic schemes and ensure the control of such controlled PDMs, and approaches to the design and production of such mechanisms have been described (works [15][16][17][18] and others).…”

“…Cross-wheel controlled PDMs are used mainly in transmissions of passenger cars, not necessarily all-wheel drive. There are works in which it is proposed to adapt a controlled PDM to work as part of the transmission of a tractor and other transport and traction machines, including skidders and forwarders, typical for the timber industry (see [15][16][17][18] and others).…”

“…In the domestic literature, despite the fundamental theoretical work in the field of the theory and design of differentials (see, for example, work [19]), the topic of controlled crosswheel controlled PDMs is represented by a few publications ( [15][16][17][18] and others).…”

“…When such vehicles are fully loaded, it is advisable to transfer up to 2/3 of the power to the wheels of more loaded drive axles, which can realize a greater traction force. In the application to a monohull all-wheel drive vehicle, a similar problem is considered, for example, in [18].…”

The article analyzes the experience of using gear controlled power distribution mechanisms in transport engineering as part of a dynamic stabilization system for high-speed ground vehicles. An overview of the sources on this issue is given. It is shown that the issue of increasing the lateral stability against skidding is relevant in modern conditions and has received a mathematical description mainly in the application to passenger cars. Attention is paid to theoretical studies of Russian scientists involved in the problem of power distribution control in transmissions of transport vehicles and tractors for various purposes. A solution to the problem of full control over the distribution of torques in a transmission containing several drive axles is proposed in the form of a structural diagram of a transmission based on the use of controlled gear power distribution mechanisms. The considered solutions are applicable for monohull vehicles and road trains with an active trailer link. Methods for determining external parameters (gamma of gear ratios) for interaxle and interwheel controlled power distribution mechanisms are proposed in the application to the case of turning a road train with an active trailer-dissolution having an electromechanical transmission.

The article presents the results of mathematical modeling of the stability of a logging machine with a vertically held tree when it is removed from the canopy of the forest. The calculation schemes for two positions of a vertically held tree are described. The substantiation of the idealization for the calculation schemes of a vertically held tree is given. The dynamic stability equations of a logging machine with a vertically held tree are constructed on the basis of second kind Lagrange equations system. Due to analyze the interrelationships between dynamic parameters and processes of a logging machine with a vertically held tree, motion differential equations were integrated taking into account external influences and initial conditions. Using the MATLAB program, the integration operations of second kind Lagrange equations system were carried out for two cases: 1) The vertical tree is rigidly fixed and repeats the deviations of the logging machine; 2) The tree is perfectly held vertically with any deviations of the logging machine. The input parameters for the calculation were the rigidity of the connections, the parameters of the logging machine, the gripping cutting device (GCD) and the tree. The parameters of the slope of the logging machine were set using the implementation of a Gaussian random process with a given correlation and variance. The dynamic stability study of a logging machine with a vertical tree showed that the ideal tree alignment in a vertical position leads to a decrease in the inertia moment of the system and to a significant decrease in the frequency of angular and linear oscillations compared with a rigidly fixed tree.
