Mounting post 23 is metalwork.
The earthed system 100 of the rail vehicle of the present embodiment simplifies the structure of earthing or grounding means 1, reduces earthing or grounding means 1
Volume so that rail vehicle is in the process of running, earthing or grounding means 1 is not easy to the object interference of surrounding, it is ensured that leads
The close contact of electric piece 12 and earth orbit 2, guarantees the ground connection performance of earthing or grounding means 1, reduces earthing or grounding means 1 and earth orbit 2
Contact area extends the service life of earthing or grounding means 1 so as to reduce the abrasion of conductive sheet 12.And it is possible to simplify ground connection
The mounting structure of rail 2 eliminates the mounting rack that traditional earth orbit 2 uses, so that the easier for installation and reduction of earth orbit 2
Cost, while can guarantee that enough distances can be kept between the contact surface 211 of earth orbit 2 and track girder, so as to
The earthing or grounding means 1 contacted with earth orbit 2 is further reduced to interfere with track girder.
