    The paper considers a current scientific and technical problem pertaining to creation of multi-bridge wheeled chassis for highly efficient modular sugar beet harvesters of large cargo capacity and, in particular, to selection of main parameters of chassis and wheeled drive. Such machines are designed for operation under complicated soil and climatic conditions during sugar beet harvesting. Methodological rules and regulations have been developed for solution of problems pertaining to scientifically sunstantiated selection of a manufactured or developed wheeled chassis model, building-block parameters of a working device and a chassis, rational control algorithm of the unit running system while using a specified (domestic or foreign) semi-mounted equipment for beet harvesting. While solving the problem theoretical provisions for wheeled vehicles regarding specific features of a wheeled chassis for modular sugar beet harvesters with extensive mechanical or hydrostatic wheel drive of a multi-bridge propulsion system have been developed in the paper. Calculated and theoretical expressions for determination of main parameters for a wheeled chassis have been obtained and they include physical quantities of operational conditions that explicitly determine its working process. Such approach has made it possible to realize the obtained expressions as a software application which is suitable for analysis of main parameters in respect of the investigated harvester chassis and rational parameters of a branch wheel drive and also for a complete set of tires in the case when a sugar beet harvester is designed on the basis of wheeled chassis according to the selected scheme. Investigations have theoretical significance and represent practical interest for development spesialists of new modular multi-bridge sugar beet harvesters.Статья посвящена актуальной научно-технической проблеме создания многомостовых колесных шасси высокоэффективных модульных свеклоуборочных комбайнов большой грузовместимости, в частности выбору главных параметров шасси и колесного привода. Такие машины предназначены для эксплуатации в сложных почвенноклиматических условиях уборки сахарной свеклы. Разработаны методические положения решения задачи научно обоснованного выбора модели колесного шасси из числа выпускаемых или разрабатываемых, параметров агрегатирования рабочего аппарата и шасси, рационального алгоритма управления ходовой системой агрегата при работе с заданным (отечественным или зарубежным) полунавесным оборудованием для уборки свеклы. При решении задачи развиты положения теории колесных машин применительно к специфике колесных шасси модульных свеклоуборочных комбайнов с механическим или гидрообъемным разветвленным приводом колес многомостового движителя. Получены расчетно-теоретические выражения для определения главных параметров колесного шасси, включающие в явном виде определяющие его рабочий процесс физические величины эксплуатационных условий. Это позволило реализовать полученные выражения в виде программного приложения, удобного для анализа главных параметров исследуемого шасси комбайна и рациональных параметров разветвленного привода колес, а также комплектации шинами в случае проектирования свеклоуборочного комбайна на основе колесного шасси выбранной схемы. Исследования имеют теоретическое значение и представляют практический интерес для разработчиков новых многомостовых модульных свеклоуборочных комбайнов
