Problems solved by technology

[0006] However, Figure 3 is also obvious, that is, due to the existence of the thin layer of rubber 19, the electrical conductivity of the axlebox rubber pad cannot be realized by connecting the upper and lower liners with wires, thus There may be a potential difference between the vehicle and the ground and the track, which will bring safety hazards to the vehicle operators standing on the ground

Embodiment 1

[0028] Figure 4 It is a structural schematic diagram of an embodiment of the axle box rubber pad of the present invention, Figure 5 for Figure 4 A partial enlarged view of the A region in the combined Figure 4 and Figure 5 As shown, the axle box rubber pad of this embodiment can be used for the bogie of a railway freight car, which can include an upper liner 16, a lower liner 17, and a rubber layer 18 formed between the upper and lower liners by vulcanization, respectively formed on the upper and lower liners. A thin layer of rubber 19 on the outer surface of the liner, a glue injection hole 20 , and a conductive mechanism built in the glue injection hole 20 .

[0029] Specifically, the glue injection hole 20 can be arranged at the middle position of the axle box rubber pad, and the glue injection hole 20 can include a cavity formed in the rubber layer 18, a first hole on the upper liner and a first hole on the lower liner respectively. The second hole on the top, the...

Embodiment 2

[0047] This embodiment provides a bogie, the bogie includes a bolster, a side frame and a wheel set, the side frame is connected to the wheel set through a bearing saddle provided at the end of the wheel set; the side frame is connected to the wheel set Axle box rubber pads for elastic buffering are arranged between the bearing saddles.

[0048] The main difference between the bogie in this embodiment and the bogie in the prior art is that the axlebox rubber pad can be the axlebox rubber pad described in the first embodiment. By adopting the axle box rubber pad, the electrical conduction between the side frame and the bearing saddle can be realized while the surface of the liner is provided with a thin layer of rubber, which not only overcomes the high manufacturing precision requirements of the upper and lower liners and the tendency to wear, It is not easy to have poor contact with the side frame and the bearing saddle, but it can also realize the conductive function.

Abstract

The invention provides a rubber gasket of a journal box and a bogie. The rubber gasket of the journal box comprises a rubber injection hole and a conductive mechanism, wherein the rubber injection hole comprises a hollow cavity, a first hole and a second hole, the hollow cavity is formed in a rubber layer, the first hole is formed on an upper lining board, the second hole is formed on a lower lining board, and the hollow cavity, the first hole and the second hole are communicated; and the conductive mechanism is arranged in the rubber injection hole, and both ends of the conductive mechanism penetrate out from the first hole and the second hole respectively and contact with the two conducted components. By the rubber gasket of the journal box and the bogie of the embodiment of the invention, the rubber gasket of the journal box not only can overcome the defects of high requirement on the manufacturing accuracy of the upper lining board and the lower lining board, easy abrasion and easy poor contact with a side frame and an adapter, but also can realize a conductive function.

Description

technical field [0001] The invention relates to railway vehicle component technology, in particular to an axle box rubber pad and a bogie. Background technique [0002] Railway freight cars generally include parts such as car body, bogie and braking device. Among them, the most common bogies on railway wagons are two-axle cast steel three-piece bogies. like figure 1 as shown, figure 1 It is a structural schematic diagram of a bogie in the prior art. The bogie includes a bolster 11 , two side frames 12 and two wheel sets 13 . [0003] Wherein, the end of the wheel set 13 is provided with a bearing saddle 14 , and the side frame 12 can be connected with the wheel set 13 through the bearing saddle 14 . In order to improve the dynamic performance of the vehicle, an axle box rubber pad 15 can be installed between the side frame 12 and the bearing saddle 14, and the axle box rubber pad 15 can realize elastic positioning between the wheel set 13 and the side frame 12, reducing...
