The invention discloses a draft gear of a
bogie. The draft gear comprises a traction central pin, a traction central seat, a traction rubber
pile, anti-overfilling dogs and a lifting pad, and the draft gear further comprises a lifting pad which is fixedly arranged at the lower part of the lifting pad, wherein the outer
diameter of the lifting pad is larger than a space between the anti-overfilling dogs, the maximum width of the traction central seat is smaller than the space between the anti-overfilling dogs, the anti-overfilling dogs are arranged at the middle lower position of a mounting hole wall of the draft gear of the
bogie, and the lifting pad and the anti-overfilling dogs are matched to realize a lifting operation. According to the draft gear of the
bogie, disclosed by the invention, based on the original structure, on the premise of not changing other component joints of the bogie, the structure of the bogie is optimized so that the draft gear can be assembled without overturning the bogie; and therefore, a bogie overturning
assembly step is omitted, the
assembly process is simplified, the production efficiency is improved and the production cost is saved.
