The article considers the ways to efficiently distribute power in terms of adhesion in a small utility vehicle under difficult road conditions with significant external resistance forces and a non-uniform support surface. Thus, four-wheel drive vehicles are usually used for operation under such road conditions, while adaptive redistribution of power supplied to the wheels is a promising method reserve for improving their energy efficiency and controllability. The paper presents a device and a mechanism to fold half-frames with the ability to control the angular speeds of rotation. A system has been modulate in the MATLAB Simulink environment. This system makes it possible to estimate the change in the position of two halves relative to their connection, depending on the applied control torque and the specified rotation angle. The developments presented in the article will improve the controllability of small-sized utility vehicles with an articulated frame and, as a result, improve the quality of the work performed. In addition, this development can be used in other types of equipment.
