Development of the Concept of Energy Saving Traction Drive of the Locomotive

Abstract

The relevance of improving existing and developing new traction drive systems for locomotives is shown. The development of the concept of an energy-saving traction drive is considered. For electric current traction amplifiers, a device for increasing the traction of a wheel with a rail is proposed, which has a contactless capacitive current collector. Several designs are proposed that make it possible to place an inductor of sufficient size and weight on the axis of the wheelset. As a design requiring minimal changes in the carriage, a chordal arrangement of the inductor is proposed when using a ferromagnetic core to enhance the magnetic flux. The design of the body supports is proposed, the use of which will increase the coefficient of using traction weight, reduce power losses and increase the efficiency of energy conversion and the realization of traction properties of the drive.
