The utility model is characterized in that: the transmission device comprises a brush holder which is fixed by insulated supports and is provided with cable connecting terminal, three brush boxes of built-in electric brush are arranged on the upper equal part of the circumference, the circle center of the circumference is the circle center of the brush holder, the terminal of the electric brush is connected with the brush holder through a soft wire splice, and a compression spring is arranged between the terminal of the electric brush and the brush holder which enables the electric brush terminal and the circular friction tray to be closely contacted. The utility model has the advantages of rational structure, perfect application effect, and effective realization of the safe grounding of the electric locomotive, simultaneously, protection of the bearing and good market prospect.
Description
Technical field
The utility model relates to a kind of earth system, specifically is a kind of electric locomotive earth system.
Background technology
At present, in order to guarantee the electric current normally of electric locomotive circuit on side of overhead contact line, loop current flows into wheel by car body through bearing, and then through the rail safety ground, but, easily cause bearing failure owing on bearing, be added with voltage for a long time.
Summary of the invention
The utility model provides a kind of electric locomotive earth system for the earthing mode that solves present electric locomotive and adopt easily causes the problem of bearing failure.
The utility model is to adopt following technical scheme to realize: a kind of electric locomotive earth system, comprise the circular friction disc that is fixed in electric locomotive axletree end, and be fixed on the locomotive axle box with circular friction disc over against the power transmitting device of installing, described power transmitting device comprises and supports with axle box fixing by insulation, which is provided with the brush holder of cable eye, it is equal brush box of the built-in brush that is provided with of portion on the circumference in the center of circle with brush holder center (being brush holder and axletree corresponding point) that brush holder is provided with three, brush is terminal to be connected with brush holder by soft line, and is provided with the compression spring that makes brush head end and circular friction disc closed contact between brush end and the brush holder.During use, cable eye on the brush holder of the earth cable of electric locomotive circuit on side of overhead contact line and power transmitting device is linked to each other, loop current transfers to brush holder through earth cable like this, transfer to brush through soft line again, finally via with the circular friction disc of brush friction (under the effect of compression spring, brush and circular friction disc closed contact, in the locomotive traveling process, circular friction disc rotates with wheel, axletree, with brush friction) transfer to axletree, and transfer to rail through wheel, realize the purpose of safety ground.
Compared with prior art; the utility model is by being provided with the fit structure of circular friction disc and power transmitting device at the axletree two ends; circular friction disc can reach 30 years wear-resisting service life; the power transmitting device conductive capability is strong; rated current reaches three times (being 600A) of prior art; can protect bearing by actv., realize the purpose of electric locomotive safety ground simultaneously.
The utility model is rational in infrastructure, and result of use is good, and the protection bearing has good market outlook when effectively realizing electric locomotive safety ground purpose.
