Maneuverability and off-road capability of a four-axle vehicle with swivel bogies and electrically driven wheels

Abstract

Problem. The issues of maneuverability and off-road capability in four-axle vehicles involve ensuring their efficient operation on rough terrain, in narrow or confined spaces, and under challenging operating conditions. Key challenges include reducing the turning radius, achieving even load distribution across axles, and minimizing energy losses during movement. Additionally, it is crucial to ensure the reliable performance of all drivetrain components, particularly under increased wear and exposure to external factors. Goal. The objective of the study is to develop and substantiate technical solutions aimed at improving the maneuverability and off-road capability of four-axle vehicles by optimizing the design of the running gear, implementing innovative drives, and enhancing the control system. This will ensure the efficient operation of vehicles under challenging conditions, improve their energy efficiency and reliability, and expand the scope of their applications. Methodology. The methodology for implementing the maneuverability and off-road capability of a four-axle vehicle with swiveling bogies and electric wheel drive includes the analysis and modeling of the vehicle's reaction to various operating conditions, as well as optimizing the drive and control systems to ensure high movement efficiency on challenging routes. Results. The results of the research on the maneuverability and off-road capability of a four-axle vehicle with swiveling bogies and electric wheel drive have improved the turning efficiency of such a vehicle on challenging terrain with steep slopes and uneven areas without road coverage. By optimizing the design of the bogies and implementing electric wheel drives, it was possible to reduce the weight and geometric parameters of the vehicle, allowing for more precise maneuvers in confined spaces while maintaining stable movement with sufficiently high off-road capability and aneuverability of the four-axle vehicle. Originality. The originality of the research lies in the comprehensive approach to improving the maneuverability and off-road capability of a four-axle vehicle with swiveling bogies and electric wheel drive. For the first time, innovative methods for optimizing the design of the running gear and implementing electric drives were applied, which significantly reduced energy losses and improved motion control on challenging terrain. New approaches to modeling movement ensured high maneuvering efficiency under various operating conditions. These results provide new opportunities for the application of such vehicles in specialized industries where the requirements for off-road capability and maneuverability are extremely high. Practical value. The practical significance of the research lies in the potential implementation of the developed technical solutions in the production of four-axle vehicles for operation in challenging conditions, such as construction, agriculture, and military applications. The improvements developed allow for enhanced equipment efficiency, reduced energy consumption, and high maneuverability and off-road capability on difficult routes.
