Continuously variable hydrovolumetric mechanical gearbox for 220-240 hp tractors
Abstract
An original continuously variable two-engine hydrovolumetric mechanical gearbox with ГСТ-112 hydraulic units for wheeled tractor with breaking frame (of ХТЗ-220 class) and 220-240 hp motor is presented. It ensures tractor operation in four velocity ranges with continuously velocity variation in the limits of every range.

Initial data for the calculation of fluid flywheel for internal combustion engine fan drive
Abstract
Procedure of initial data generation for calculation and designing of fluid flywheel for internal combustion engine fan drive is given. Fans can be devices of air or fluid cooling, and cooling draught inlet can be axial and radial-axial. The central purpose is to generate algorithm and software for personal computer with maximal exploitation of analytical dependences instead of graphs.

A conceptually new textbook
Abstract
В начале 2013 г. в издательстве «Инфра-М» выходит из печати второе издание учебника «Тракторы и автомобили», принципиальное отличие которого от аналогичных состоит в том, что в нем наряду с теорией трактора впервые изложены методы оценки его технологических и тягово-динамических свойств. Ранее эти методы в вузах не изучались. Благодаря новым разделам предлагаемый учебник станет первым максимально приближенным к эксплуатационному направлению, по которому с.-х. вузы готовят специалистов инженерного профиля.
