Abstract

Every year the number of selfpropelled machines equipped with hydrovolumetric mechanical transmissions increases. In the process of creation of new hydrovolumetric mechanical transmission the designers faced a number of difficult issues: the choice of optimal structural chart, determination of necessary parameters of hydrovolumetric transmission, etc. The article examines the influence of hydromotor volume on the main parameters of hydovolumetric mechanical transmissions working according to the scheme "output differential."  The article represents the kinematic scheme of hydrovolumetric mechanical transmissions with different connection of mechanical and hydraulic strand with units of planetary train (sun gear, crown gear, cage). There are definitions of kinematic, force and energy parameters of given transmission, efficiency of hydrovolumetric transmission and transmission in general at different volumes of hydromotors. The analysis of hydrovolumetric mechanical transmission with output differential showed that using hydromotor of maximum volume of 250 cm3 instead of 130 cm3 we can observe the reduction of the maximum pressure to 0.04 - 17.92% , the maximum power output to0.14 - 6.54%, the maximum angular velocity of hydromotor shaft to 36.96 - 49.74%, the  increase of maximum angular velocity of the shaft of hydropump to 0.0 - 15.72%, the change of maximum efficiency value in the range 2.23 - 0.80%, the change of maximum angular velocity of satellites in the range -48.45 - 4.15%.
