CONTACT INSERT OF SUSPENSION ELECTRIC MOBILE COMPOSITION

Utility model for line collectors

power supply of electric vehicles, in particular

to the contact inserts of the electro-current collectors

composition, and can be used for railway and

city electric transport.

Known contact insert current collector electromotive

composition described in clause of the Russian Federation No. 2104884 "Electrically conductive

contact insert of current collectors of vehicles according to cl.

B60L 5/00, 5 / 20.3. 10.24.94, op. 02/20/98.

Known contact insert is made in the form of a removable plate

from carbon-carbon material, for example, KIMF,

used in space rocket technology and is very

wear-resistant, but very expensive.

Known contact insert current collector electromotive

composition described in a. from. USSR No. 1047743 "contact plate

for current collector according to cl. B60L 5/08, c. 16.11., Op. 10/15/83.

Known contact insert contains a body of sintered

the material in which the reinforcing element is made, made

in the form of perforated and corrugated in the longitudinal

direct the plates.

A disadvantage of the known insert is the difficulty of manufacturing

(rolling) and the relative complexity of the design.

trolley bus collectors and conductive composite material for its manufacture according to cl. B60L 5/08, c. 06/03/97, op. 05/20/99.

The well-known insert u) is intended for trolley buses and is made in the form of a plate of pressed powder composite material based on graphite with a working part corresponding to the profile of the contact wire, while it is made of a two-layer - top layer, which is 65-70% of the volume of the insert and made of composite graphite-based material, and a lower layer comprising 30-35% of the insert volume and made of a graphite-based composite material with a metal additive in the form of a powder with a particle size n more than 150 microns.

A disadvantage of the known insert is the complexity of its design and the complexity of the composition in terms of the different materials used. Closest to the technical nature of the claimed is the contact insert described in a. from. USSR No. 337281 Material for current collector inserts for current collectors for electric rolling stock in class. B60L 5/20, c. 07.26.63, op. 05/31/72 and selected as a prototype.

The known contact insert is made on the basis of a carbon-graphite composition from coke-graphite grinding and phenol-formaldehyde resin and is a body pressed along the insert profile.

A disadvantage of the known contact insert is its low wear resistance, which is explained by the fact that when the insert is pressed, its base always has a slight convexity, which does not provide reliable contact with the current collector run, full current collection and accelerates wear of the insert.

The purpose of the claimed utility model is to increase the wear resistance of the insert and improve current collection by ensuring reliable contact with the runner slip. This goal is achieved by the fact that in the contact insert of the current collector of electric rolling stock, which is a composition based on graphite and phenol-formaldehyde resin and made in the form of a profile plate with a working surface and a base, ACCORDING TO THE USEFUL MODEL, the base is made with a milled surface.

The implementation of the contact insert with a milled base allows to improve the contact of the insert with the current collector skid, which reduces wear and reduces current collection.

The inventive contact insert has a novelty in comparison with the prototype, distinguishing itself from it by such an essential feature as milling of the surface of the base, ensuring the achievement of a given result.

The inventive contact insert of the current collector of electric rolling stock can be widely used in electromotive railway and urban electric vehicles, and therefore meets the criterion of "industrial") availability.

The inventive utility model is illustrated in the drawing, which shows a General view of the contact insert.

The inventive contact insert of the current collector of the electric rolling stock is a profile plate 1 with a working surface 2 and a milled base 3, made on the basis of graphite and phenol-formaldehyde resin.

In the process, the working surface 2 of the insert touches the wire of the contact line and removes current from it for transmission through the base to the electric locomotive for consumption. Thanks to even and smooth after

milling the surface of the base 3 there is more contact of the insert with the runner slide, better current collection and less wear.

In comparison with the prototype of the inventive contact insert is more durable and provides improved current collection.
