Podrigalo N. Conception of performance engineering and control of motor transaxle functional stability of transport hauling equipment

The thesis is devoted to solving the problem of efficiency and control the functional stability of the motor transaxle of transport hauling equipment and is aimed at improving their efficiency both at the designing stage, and repair with modernization, as well as follow-up of functional stability during its performance with the help of an integrated indicator - efficiency. The results obtained concerning the development of the conception of efficiency and control the functional stability on the stage of design, manufacture and operation of transmission systems for transport and traction machines. To evaluate the unnecessary loss of energy motor transaxle used criterion - transmissions efficiency. With the efficiency criterion is developed methods of diagnosing motor-gear units under operating conditions and in the manufacture of transport and traction machines. The scientific significance of the work lies in the formation of the conception of increasing the functional stability of the motor transaxle of transport and traction machines and the development of the existing theory of estimation of unproductive energy losses in internal combustion engines. The practical significance of the results is to develop a set of guidelines to improve the transmission efficiency on the design stage and test methods of traction with the acceleration and coasting on test-bed and in the road conditions of operation of transport and traction machines.
