The problem of import-substituting components for the support-axial traction drive of an electric train with a wheel diameter of 950 mm is considered. As a result of the analysis, the disadvantages of the drive using foreign components are revealed: a high unsprung mass, which worsens the impact of the crew on the track, the difficulty of providing the required dynamic properties with elastic support of the motor-gear unit on the axle, the complexity of manufacturing and assembling the drive. The inexpediency of copying foreign solutions to create a domestic analogue of a traction drive is established. Variants of technically possible traction drive adapted for domestic production and easier to manufacture are considered. It is proposed to use a traction drive with a high-torque support - frame traction engine, with an increased outer diameter and the same circumferential speed of the rotor and an axial gearbox. It is proved that in this case, due to a decrease in the speed of the drive shaft, the design of the gearbox is simplified, which can be made single-reduction, and it becomes possible to use the developed and studied domestic flat rubber-cord couplings. A new design of the transverse rubber-cord coupling is proposed. For the case of using a domestic high-speed traction electric motor in the drive, it is proposed to use an aggregate-type traction drive. Two utility model patents are obtained for the proposed technical solutions and a patent application is filed.
