Kurchev, Registration Date 24-09-2007 Organization Tavria State Agrotechnical academy popup.description2 The hydravlic drive of propel systems of automotive agricultural machines was investigated in a work? because the gain in performance of using the mobile agricultural machines is greatly determined with implementation of hydraulics in their propel systems. The fulfilled analysis of foreign mobile agricultural machines shows that practically all the technology is equipped with hydrostatic transmissions (HST) of propellers. High operational qualities of HST are established in the testsof different types of combines. The engine of an automotive machine has significant reserve of the power, that is why the HST set on it can work in the different regimes of load determining the temperature regime, and consistently, the operability of details and the durability of hydravlic aggregates. At the maximum flow rate of the pump and equal torques, the effeciency of the whole HST amounts 88% for three-aggregate scheme of the hydrostatic drive of propel systems and 82% - for two-aggregate scheme/ Product Description popup.authors popup.nrat_date 2020-04-02 Close
