Abstract
The analysis malfunctions of the main modules of the traction and motor-vehicle rolling stock components operated in the regional branch of "Southern Railway" PJSC "Ukrainian Railway" has been confirmed. It is noted that the traction drive accounts for almost a third of all malfunctions of rolling stock. The urgency of research and development works aimed at improving the designs of existing traction drives is grounded in order to increase their reliability. The existing approaches to the classification of traction drives are described. The mentioned disadvantages of the classification, taking into account only the degree of subgrade of the traction electric motor and gearbox. An approach to the modular description of the design of a modern traction drive is considered. Using the principles of hierarchy and blocking (decomposition), a new modular-decomposition description of traction drives is proposed. At the same time, five hierarchical levels with a certain amount of decomposition elements were allocated on each of them. At the first level, the description of the design is the most generalized. In turn, the decomposition elements of the fifth level are the constituents of the design of the main modules, which are accepted by the base ones. This description allows to consider separate structural elements included in the main modules (for example, for the module of traction gear transmission the basic elements adopted the upper and lower gear casing, mounting elements, gear, gear shaft, gear, sealing elements). Of particular importance is the use of the proposed approach in solving complex scientific and technical problems associated with increasing the reliability of the functioning of traction drives. An example of the application of the proposed description in the analysis of faults of elements of the traction tooth gear unit of the traction drive of the motor wagon rolling stock of the EP series is given.
