In bright first embodiment, the effect when dismounting in dismounting portion 41 is best.
Preferably, above-mentioned overlapping regions includes the first end and the second end, and lock ring body 41 is arranged to circular ring, overlapping regions
Corresponding central angle is b, wherein, 30 °≤b≤90 °.
Central angle b corresponding for overlapping regions is arranged to 30 °≤b≤90 °, the overlapping regions of brake shoe lock ring can be made to expand, from
And make brake shoe lock ring be not easily susceptible to external force deformation and produce opening, and then prevent brake shoe lock ring from being deviate from by installation site.
The central angle b that in first embodiment of the invention, overlapping regions is corresponding, value be b=60 °.B is arranged to 60 °, can
Also will not be too small so that overlapping regions is the most excessive such that it is able to ensure overlapping regions has enough Guan Bis when closed state
Elasticity, but overlapping regions is opened by the personnel that will not hinder one's work.
It should be noted that above-mentioned brake shoe lock ring uses high strength steel to make, it is preferable that the steel wire that spring steel is made can be used
Make above-mentioned brake shoe lock ring.Wherein, a diameter of 30mm of the lock ring body 41 in first embodiment of the invention, gauge of wire
For 2.5mm.But the diameter of the lock ring body 41 of the present invention and steel wire diameter are not limited to dimensions above, it is being applied to different knot
During structure, can the corresponding diameter changing lock ring body 41 and gauge of wire, even change shape and the steel of lock ring body 41
The cross sectional shape of silk.
Further, above-mentioned dismounting portion 42 can be arranged to linear type or shaped form.
The present invention is not limited to above-described embodiment, as shown in Figure 4 and Figure 5, in second embodiment of the invention, and above-mentioned dismounting portion 42
It is two, is separately positioned on the two ends of lock ring body 41.It is respectively provided with dismounting portion 42 at the two ends of lock ring body 41, pin can be made
The overlapping regions of ring body 41 easily facilitates staff's manual unlocking, thus reaches to be easy to the purpose of brake shoe lock ring dismounting.
It should be noted that in addition to features described above, in second embodiment of the invention, other features are all identical with first embodiment.
The embodiment of the present invention additionally provides a kind of bogie, including brake shoe, brake head, brake shoe key and above-mentioned brake shoe lock ring.
Specifically, brake shoe being provided with installing hole, brake head is provided with mating holes, the free end of brake shoe key sequentially passes through peace
Filling hole and mating holes and extend out to the outside of brake head, brake shoe lock ring is detachably secured to the free end of brake shoe key, to limit
The displacement of brake shoe key.
When mounted, staff manually applies external force to dismounting portion 42, overlapping regions to be opened by dismounting portion 42.Lock
It is provided with a through hole on the free end of watt lock ring.In installation process, this through hole is penetrated by the free end dismounting portion 42, and passes through
The passage that overlapping regions is formed slips in lock ring body 41, and makes lock ring body 41 and brake head clamping, to limit brake shoe key
Movement.During dismounting, operating process is contrary with above-mentioned installation operation, and here is omitted.
The embodiment of the present invention additionally provides a kind of railway freight-car, including above-mentioned bogie.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect:
Arranging dismounting portion, overlapping regions can be opened by staff by dismounting portion is manual, and makes brake shoe lock ring be installed to coordinate
Workpiece on such that it is able to reach to be easy to the manual purpose dismounting brake shoe lock ring.
Further, central angle b corresponding for overlapping regions is arranged to 30 °≤b≤90 °, the overlap of brake shoe lock ring can be made
Territory expands, so that brake shoe lock ring is not easily susceptible to external force deformation and deviates from from installation site.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for those skilled in the art
For, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of being made, etc.
With replacement, improvement etc., should be included within the scope of the present invention.
