    Opis:
    Nowadays, increasing number of machines and off-road vehicles are equipped with elastomeric, mainly rubber, tracked chassis. Rubber tracks and belts combine the most important advantages of both: pneumatic tires and conventional tracks made from metal links. In spite of significant benefits, rubber tracked chassis is a novel and uncommon design solution, as the application of rubber tracks and belts still brings up many severe problems. Consequently, an urgent need to overcome these problems exists. In The Division of Off-Road Machine and Vehicle Engineering (DORMVE) an intensive research, pertaining to rubber-tracked chassis has been conducted for many years. In the very beginnings, the investigation was carried on in cooperation with German companies INTERTRACTOR, IAMT and IBAF. As a result, numerous original and innovative design solutions, which became a subject of European, American and Japanese patents, were developed. However, some issues have not yet been resolved. Present research of DORMVE is aimed at identification of problems concerning energy efficiency of rubber-tracked chassis. The main objective of current investigation is to improve the energy efficiency. To do so a comprehensive optimisation process is to be carried out. Within the following article, a classification of aforementioned problems will be discussed. Research facilities in laboratory of DORMVE and exemplary results, which have already been obtained, will be also presented.

    Opis:
    At the beginning of the paper, the analysis of energy efficiency indicators for freight electric locomotive with asynchronous traction drive feeding from AC network under various operating conditions including when working with trains of various masses is made. The movement on different railway sections is considered. The graphs of locomotive’s speed, traction force, consumed power, and power for the traction obtained by on-board recorder are shown. In addition, the dependence of the locomotive's energy efficiency from the degree of using of its available traction capacity has been experimentally obtained, the greater is the using of the locomotive’s capacity, the greater will be its efficiency. On the basis of the performed analysis of energy efficiency indicators for various operating conditions, the proposals for their improvement are formulated. The algorithm ensuring the stabilization of the instantaneous value of efficiency at partial load to its nominal level at full load is presented. This algorithm is the implementation of Scalable Power Control Technology with respect to the problem of reducing electricity consumption for electric locomotive traction. The direct the experimental confirmation of energy consumption reduction for freight electric locomotive due to the application of our proposals (under the same operating conditions of the locomotive) is obtained.
