The thesis is devoted to increasing the efficiency of application the tractors based on hydrovolumetric mechanical transmissions (HVMT) through the determination of influence of temperature modes on hydrovolumetric transmission (HVT) characteristics justification of parameters of cooling system in HVT. The influence on temperature of working fluid on the work of hydro system has been carried out. There have been determined the approaches in the determination of temperature modes of HVT. The parameters of cooling system of HVT have been justified. There has been developed the extended mathematical model which considers the temperature, kinematics and power modes of volumetric hydraulic gear in HVMT of the wheel tractor. There also has been developed the mathematic model as a matrix that includes the description of kinematic parameters of HVMT, power parameters and energy conversion efficiency of all gearing parts and thermal characteristics. The provided research approved the adequacy of developed mathematical model. The variation of temperature of working fluid in the working and transport gear may be described as a curve with a maximum in a special zone. There has been determined the influence of temperature on general and volumetric energy conversion efficiency for the each gear and the recommendation for choosing the cooling system that consider the redistribution of power fluids in HVMT were performed.

The dissertation is devoted to increasing the braking efficiency of wheeled tractors with steady hydrostatic transmission due to the method of braking, the choice of shape and duration of the change of the parameter of regulation. The complex mathematical model of the braking process to tractor KhTZ -21021 with hydrostatic transmission is made possible to model all possible methods of braking. From the existing mathematical model, the kinematic, power and energy parameters of the steady continuously variable transmission are different, as well as the description of the drum braking mechanism with the pneumatic system in the wheel tractor KhTZ-21021. On the basis of the optimization theory it is formalized that the rational change of the hydraulic control parameter for the hydrostatic transmission with the "differential on the outlet", in terms of the braking efficiency, is a curved form. At the hydrostatic transmission laboratory stand, it has been confirmed that the best braking performance during braking with the hydrostatic transmission regulation parameter (the minimum number of revolutions of the output shaft hydrostatic transmission, and, as a consequence, the minimum braking distance) is observed for curved forms of hydrostatic transmission control, regardless of the duration of the control effect.
