The patent description was published: December 15, 1977 86088 MKP B60m 1/22 Int. Q2. B60M 1/22 Creators of the invention: Stanislaw Adamiak, Norbert Klar, Henryk Szmidt, Eugeniusz Zawiasa The holder of the patent: Centralne Biuro Studiów i Projektów Budownictwa Kolejowego, Warsaw (Poland) Electric traction network for rail vehicles Technical field. Power lines and equipment along the tracks for electric traction vehicles. State of the art. The electric traction network for rail vehicles used hitherto consists of a lifting rope suspended from the supporting structures and a contact wire suspended from the booms placed on the supporting structures. Apart from the booms, the contact wire is suspended from the lifting rope by means of hangers. The jib keeps the contact wire in the plan and the lifting rope and hangers vertical. The lifting rope and hangers create conditions enabling the flexible cooperation of the electric current collector of the traction vehicle with the contact wire, that is, the flexibility of the network. Equalizing the elasticity of the network increases the driving speed of the traction vehicle. The existing solutions for equalizing the elasticity of the traction network envisage the use of Y-type auxiliary lines, flexible hangers, building a net of two or more lines. These methods are ineffective, limit the speed of the current collector and create a number of assembly difficulties. The essence of the invention. Electric traction network for railway vehicles is composed of a lifting rope made of separate ropes connected to each other in the transmission and branched at the supporting structures. The upper part of the branched lifting rope is suspended on the support structure and the lower part of the branched rope hangs freely. The contact wire is suspended to the boom directly by using hangers, for a carrier rope, in the transmission to the common carrier rope and in the case of supporting structures for the dangling part of a branched carrier rope. The subject of the invention is shown schematically in the drawing in which Fig. 1 shows the electric traction network in the view of the ditches 2 is a traction network perpendicular to the track axis. An example of the invention implementation. The upper part of the branched lifting rope 1 hangs on the extension 2. The lower part of the branched lifting rope 3 hangs freely. The contact wire 4 is suspended from the boom 5 attached to the supporting structure 6, and then by the hangers 7 to the overhanging part, the lower, branched lifting rope 3 at the supporting structures and the common lifting rope 8 in the delivery. 2 86 088 EN
