Embodiment Construction

[0024] The bogie traction device of the present embodiment, such as Figure 3-5 As shown, the composition includes: traction center pin 1, traction center seat 2, traction rubber pile 4, anti-overcharge stopper 3, lifting pad 5, which also has a hanging pad 7 fixed under the lifting pad 5, and the outside of the hanging pad 7 The diameter is greater than the distance between the anti-overfill stopper 3, and the maximum width of the traction center seat 2 is smaller than the distance between the anti-overcharge stopper 3. In the middle and lower positions, the lifting pad 7 cooperates with the filling stopper 3 to realize lifting. The hanging pad 7 is fixed to the lifting pad 5 by the lifting pad fastening bolt 9, and the hanging pad fastening bolt 9 is screwed into the lifting pad 7 and the lifting pad 5 from bottom to top, and the lower surface of the hanging pad 7 is tightly connected to the lifting pad. Adjustment pads 8 are arranged between the upper surfaces of the fixed...

Abstract

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.

Description

technical field [0001] The invention relates to a bogie traction device, which belongs to the technical field of rail vehicle bogies. Background technique [0002] The Metropolis series bogies all adopt traction rubber pile-type traction device, which is located in the center of the bogie frame beam, which can realize the functions of anti-overfill and integral lifting. like Figure 1-3 As shown, the device includes a traction center pin 1, a traction center seat 2, an overcharge prevention stopper 3, a traction rubber pile 4, a lifting pad 5, a lifting pad fastening bolt 6, and an overfilling prevention bolt 10. The traction center pin is connected to the car body through bolts. When the car body is hoisted, the traction center pin and the traction center seat are driven, and finally the overfill prevention stopper on the bogie is supported by the anti-overfill bolt installed on the traction center seat. The whole bogie is hoisted up. like figure 2 As shown, the tractio...
