OPTIMISATION SELECTION OF A SYSTEM SOLUTION OF HYDROMECHANICAL TRANSMISSION WITH A HYDROSTATIC TRANSFORMER FOR OPERATING AGRICULTURAL TRACKED TRACTORS

摘要

Permanently existing difference in steering mechanism of agricultural tracked tractors and tractors with wheels, showed over the ergonomical characteristics in advantage of tractors with wheels, leads to radicaly new system solutions of steering tracked tractors. In this case theoretical and experimental bases are given in projecting hydromechanical system of transmitting power - HMSTP with hydrostatic torque transformer - HSTT for power and steering of tracked tractor.
