The air spring limiting device disclosed by the embodiment of the invention can be used for tensioning and limiting through the limiting connecting rope 310 in the overcharged state of the air spring 300 to prevent the height of the magnetic suspension vehicle from being excessively increased, and can play a role in supporting the weight of the magnetic suspension vehicle when abnormal load or the air spring 300 is not aerated.
Compared with the prior art that the threaded rod is matched with the limiting device of the cotter pin to restrain the upper limiting backstop and the lower limiting backstop of the air spring, the steel wire rope of the air spring limiting device disclosed by the embodiment of the invention is a flexible part, can adapt to the position deviation between the swing bolster and the air spring support beam along the radial direction of the steel wire rope, and is strong in deflection adaptability to the air spring, simple in structure installation and convenient to overhaul.
The swing bolster 100 is provided with a fixing hole for fixing the air spring limiting device, a fixing nut 101 is arranged in the fixing hole, a first connecting piece is used for being in threaded fit with the fixing nut 101, and in order to realize the fixing function of the first connecting piece, the first connecting piece comprises a first threaded connection part 311 used for being connected with the swing bolster 100 and a first pressing part 313 used for being connected with a steel wire rope 317.

The second connector further comprises a second profile fitting 315 for fitting with a tool to rotate the second threaded connection 316, the second connector being screwed to the limit support by rotating the second profile fitting 315.
The first profile engaging portion 312 and the second profile engaging portion 315 may be both of an outer hexagonal structure. It can be understood by those skilled in the art that the outer surfaces of the first profile matching part 312 and the second profile matching part 315 can be driven to rotate with following by the action of the dismounting tool as long as they are non-circular cross sections, and the outer hexagonal structure is only a common profile structure, but not the only structure.
In one embodiment of the present disclosure, the limit support is a fastener 334 that is threadedly engaged with the second threaded portion 316. The fastener 334 may be a nut for threaded connection with the second connector. The limit support portion is used for blocking the lower limit stop assembly 330 so as to prevent the lower limit stop assembly 330 from coming off downwards along the axial direction of the steel cable 317. And allows the lower limit stopper assembly 330 to limit the air spring 300 along with the limit connection rope 310.
Referring to FIG. 6, to limit the compression limit of air spring 300, upper limit stop assembly 320 includes an upper limit stop 322 and a building block. The wire rope 317 penetrates through the upper limit stopper 322, and the upper limit stopper 322 is used for limiting a first limit gap of the compression limit of the air spring 300.
Because the spacing connecting rope 310 is provided with the flexible steel wire rope 317, one end of the first connecting piece cannot be locked by applying torque to one end of the second connecting piece during installation, and therefore, enough torque fastening space is obtained for installation of the first connecting piece by reducing the size of the upper limiting stop 322 and increasing the splicing pad. Specifically, the splice pad is disposed between the upper limit stopper 322 and the joist limiting portion 201, and has a pad via hole through which the steel wire rope 317 passes, and the splice pad has a rope embedding channel communicated with the pad via hole to be embedded into the steel wire rope 317.
When the first connecting piece of the limit connecting rope 310 is fixed with the swing bolster 100, one end of the limit connecting rope 310, provided with the first connecting piece, sequentially penetrates through the joist limiting part 201 (a joist perforation used for penetrating through the steel wire rope 317 is arranged on the joist limiting part 201) and the upper limit stop block component 320, at the moment, an assembling cushion block is not installed firstly, a larger rotating space is reserved for the first profile matching part 312, the first profile matching part 312 is rotated to be fastened with the fixing nut 101, and finally the assembling cushion block is installed between the upper limit stop 322 and the joist limiting part 201, and the steel wire rope 317 is embedded into the cushion block through hole from the rope embedding channel, so that a first limit gap for limiting the compression limit of the air spring 300 is formed between the upper limit stop block component 320 and the swing bolster installation part 104. And the assembly cushion block is arranged at last, so that a larger installation space can be provided for fastening the first connecting piece, and during disassembly and assembly, the assembly cushion block can be disassembled at first, and then the disassembly and assembly operation of the limiting connecting rope 310 is carried out.
Those skilled in the art will appreciate that the rope-embedding channels of the building blocks may be channels that communicate directly with the block via holes, as long as the steel cables 317 are able to penetrate the block via holes from the outer surface of the building blocks.

First installation divides cushion 324 to have first cushion half-hole and first joint portion, and second installation divides cushion 325 to have second cushion half-hole and second joint portion, first joint portion and second joint portion joint to make first cushion half-hole and second cushion half-hole form the cushion via hole. When the first mounting sub-spacer 324 is engaged with the second mounting sub-spacer 325, the first mounting sub-spacer is disposed between the upper limit stopper 322 and the joist spacing portion 201, and limits the first limit gap of the compression limit of the air spring 300 together with the upper limit stopper 322. When the first mounting sub-spacer block 324 and the second mounting sub-spacer block 325 are separated, a gap between the first mounting sub-spacer block 324 and the second mounting sub-spacer block 325 is a rope insertion passage so that the wire rope 317 can be inserted from between the first mounting sub-spacer block 324 and the second mounting sub-spacer block 325.

Specifically, the first installation sub-cushion block 324 and the second installation sub-cushion block 325 can be installed in an elastic clamping manner, that is, when the first installation sub-cushion block 324 and the second installation sub-cushion block 325 are close to each other, when the clamping protrusions (the first clamping protrusions and the second clamping protrusions) are embedded into the clamping grooves (the first clamping grooves and the second clamping grooves), the clamping protrusions deform themselves, so that the clamping protrusions can pass through the narrow openings of the clamping grooves, and after the clamping protrusions completely enter the clamping grooves, the shapes of the clamping protrusions are restored, and a clamping structure is formed.
The first installation sub-cushion block 324 and the second installation sub-cushion block 325 can be installed in an inserted mode, namely the first installation sub-cushion block 324 moves along the direction that the upper direction or the lower direction of the second installation sub-cushion block 325 is close to the second installation sub-cushion block 325 along the axial direction, so that clamping protrusions (first clamping protrusions and second clamping protrusions) are gradually inserted into clamping grooves (first clamping grooves and second clamping grooves) through end faces, the clamping protrusions do not need to deform, installation can be completed, and a clamping structure is formed.
