Abstract
The present invention provides an journal box rubber pad and a bogie, wherein the journal box rubber pad comprises a glue-injection hole and a conductive mechanism: the glue-injection hole comprises a cavity formed in a rubber layer, a first hole formed on an upper wear liner and a second hole formed on a lower wear liner. The cavity, the first hole and the second hole are communicated with each other; the conductive mechanism is placed internally in the glue-injection hole; the two ends of the conductive mechanism pass through the first hole and the second hole respectively and be in contact with two conducted apparatuses. The journal box rubber pad and the bogie of the present invention have the advantages that: the journal box rubber boxes not only can overcome the disadvantages that the upper and the lower wear liners are easy to be abraded and have poor contact with a bogie side frame and an adapter because of the requirements of high manufacturing accuracy but also can realize conductive function.
