Description
Technical field
The utility model relates generally to rail traffic vehicles parts, relates in particular to a kind of rail traffic vehicles torsion bar mechanism for preventing side rolling of train carriage.
Background technology
Along with the high speed development of track traffic in recent years, use to track traffic in daily life is more and more frequent, convenience, traveling comfort and security requirement to track traffic are more and more higher, not only require guideway vehicle parts function admirable, more need often key position part to be carried out to Inspection and maintenance, immediately find and eliminate safe hidden trouble.Anti-side rolling torsion rod is except more and more higher to reliability design requirement, also more and more higher to the convenience requirement of safeguarding, and convenient operation does not affect again its safety performance in the time of torsion bar entrucking and dismounting.
In prior art, torsion bar two ends assembling steel friction sleeve mode is taked interference fit, needs heating assembling, needs strictly to control the finish size of steel construction piece in fitting process, and the process of wanting monitor closely hot charging to join, prevents in fitting process because assembling magnitude of interference problem scratches torsion bar.And steel friction sleeve has assembled rear removal difficulty, if torsion bar assembly needs to be serviced or the wearing and tearing of steel friction sleeve are changed, adopt traditional approach to remove the steel friction sleeve torsion bar axle that is very easy to damage, cause part to be scrapped.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of rail traffic vehicles torsion bar mechanism for preventing side rolling of train carriage of simple in structure, easy to loading and unloading, long service life is provided.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of rail traffic vehicles torsion bar mechanism for preventing side rolling of train carriage, comprise torsion bar axle, described torsion bar axle is equipped with support sleeve in two ends outer cover, between described torsion bar axle and support sleeve, is provided with high molecular abrasion-proof layer, and described high molecular abrasion-proof layer is connected with torsion bar axle outer wall and support sleeve inwall respectively.
Further improvement as technique scheme:
The thickness of described high molecular abrasion-proof layer is d, 5mm≤d≤8mm.
Described high molecular abrasion-proof layer is PTFE coat.
Described high molecular abrasion-proof layer and torsion bar axle outer wall are bonding, and described high molecular abrasion-proof layer and support sleeve inwall are excessively connected.
Compared with prior art, the utility model has the advantage of:
Rail traffic vehicles torsion bar mechanism for preventing side rolling of train carriage of the present utility model, between torsion bar axle and support sleeve, be provided with high molecular abrasion-proof layer, high molecular abrasion-proof layer is connected with torsion bar axle outer wall and support sleeve inwall respectively, it is simple in structure, easy to loading and unloading, compared with conventional confguration, between this torsion bar axle and support sleeve, install high molecular abrasion-proof layer, replace traditional steel friction sleeve with high molecular abrasion-proof layer, one side is due to the wear resisting property of high molecular abrasion-proof layer, can ensure the effect of resistance to wearing, on the other hand, because high molecular abrasion-proof layer also has certain shrinkage, high molecular abrasion-proof layer and torsion bar axle and support sleeve all form and flexibly connect, eliminate because the interference problem that the trickle variation that rigging position and direction occur causes, there will not be the phenomenon of assembling difficulty or damage torsion bar axle and support sleeve, and in unloading process, high molecular abrasion-proof layer is also easily removed, can scratch torsion bar axle, improve the stability of torsion bar axle and support sleeve, extend the service life of this torsion bar device.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model rail traffic vehicles torsion bar mechanism for preventing side rolling of train carriage.
Fig. 2 is the A place structure for amplifying schematic diagram of Fig. 1.
In figure, each label represents:
1, torsion bar axle; 2, support sleeve; 3, high molecular abrasion-proof layer.
Detailed description of the invention
Below with reference to Figure of description and specific embodiment, the utility model is described in further details.
As depicted in figs. 1 and 2, the embodiment of the utility model rail traffic vehicles torsion bar mechanism for preventing side rolling of train carriage, this torsion bar device comprises torsion bar axle 1, torsion bar axle 1 is equipped with support sleeve 2 in two ends outer cover, between torsion bar axle 1 and support sleeve 2, be provided with high molecular abrasion-proof layer 3, high molecular abrasion-proof layer 3 is connected with torsion bar axle 1 outer wall and support sleeve 2 inwalls respectively, it is simple in structure, easy to loading and unloading, compared with conventional confguration, between this torsion bar axle 1 and support sleeve 2, install high molecular abrasion-proof layer 3, replace traditional steel friction sleeve with high molecular abrasion-proof layer 3, one side is due to the wear resisting property of high molecular abrasion-proof layer 3, can ensure the effect of resistance to wearing, on the other hand, because high molecular abrasion-proof layer 3 also has certain shrinkage, high molecular abrasion-proof layer 3 all forms and flexibly connects with torsion bar axle 1 and support sleeve 2, eliminate because the interference problem that the trickle variation that rigging position and direction occur causes, there will not be the phenomenon of assembling difficulty or damage torsion bar axle 1 and support sleeve 2, and in unloading process, high molecular abrasion-proof layer 3 is also easily removed, can scratch torsion bar axle 1, improve the stability of torsion bar axle 1 with support sleeve 2, extend the service life of this torsion bar device.
In the present embodiment, the thickness of high molecular abrasion-proof layer 3 is d, and 5mm≤d≤8mm, in the present embodiment, d is 8mm, arranges like this, makes high molecular abrasion-proof layer 3 keep good Joint strenght, meanwhile, again torsion bar axle 1 is played to fine buffer action, further improved the stability of torsion bar axle 1.
In the present embodiment, high molecular abrasion-proof layer 3 is PTFE coat, and PTFE polymer composite had both played the effect of wear-resistance and anti-corrosion, facilitates again removal to realize secondary and adheres to, and is conducive to the updating maintenance of high molecular abrasion-proof layer 3.
In the present embodiment, high molecular abrasion-proof layer 3 is bonding with torsion bar axle 1 outer wall, be that high molecular abrasion-proof layer 3 is attached to torsion bar axle 1 outer wall, do not need heating assembling, also the problem of while there will not be traditional interference assembling, torsion bar axle 1 being damaged, and high molecular abrasion-proof layer 3 is excessively connected with support sleeve 2 inwalls, eliminate the gap between support sleeve 2 and high molecular abrasion-proof layer 3, there will not be between steel structure phase mutual friction violent, shake strong problem, further improve the stability of torsion bar axle 1 with support sleeve 2, extended the service life of this torsion bar device.
Although the utility model discloses as above with preferred embodiment, but not in order to limit the utility model.Any those of ordinary skill in the art, in the situation that not departing from technical solutions of the utility model scope, all can utilize the technology contents of above-mentioned announcement to make many possible variations and modification to technical solutions of the utility model, or be revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not depart from technical solutions of the utility model,, all should drop in the scope of technical solutions of the utility model protection any simple modification made for any of the above embodiments, equivalent variations and modification according to the utility model technical spirit.
