PARAMETRICAL SYNTHESIS OF HYDROVOLUMETRIC-MECHANICAL TRANSMISSIONS FOR VEHICLES ACCORDING TO THE CRITERION OF MAXIMUM EFFICIENCY

Abstract

In the article there is implemented the problem of parametrical synthesis of continuously variable hydrovolumetric-mechanical transmissions (HVMT) of the wheeled and track-type vehicles that perform relatively stable processes. To solve the problem of parametric synthesis of HVTM specified machines is proposed to use the criterion of the middling-integral efficiency of trasmission. Also there is implemented the definition of parametrical synthesis problem for the kinematic scheme of HVMT as a synthesis of eigenvector of constructive parameters on the criterion of HVMT maximal middling-integral efficiency when satisfying the whole set of constructive and operational constraints for deformable shape of adjusting characteristic within the defined range of technological speeds. Such formulation of the problem gives the opportunity to find the most efficient constructive parameters of the HVMT from the point of view of the higher transmission efficiency and machine efficiency. At this the problem of parametrical synthesis of the general formulation is simplified compared to previously proposed variants of such problem.
