Contact with described coupler hook body；Wherein, described buffer unit is used for slowing down described coupler hook body at laterally pendulum
The impulsive force brought time dynamic, thus improve the stability that vehicle runs；Reduce the abrasion of hitch and striker,
Thus increase the service life of hitch and striker.
Accompanying drawing explanation
A kind of railway freight-car striker that Fig. 1 provides for one embodiment of the invention matches with coupler hook body
Structural representation；
The part sectioned view of a kind of railway freight-car striker that Fig. 2 provides for one embodiment of the invention.
Detailed description of the invention
One embodiment of the invention provide a kind of railway freight-car striker, be arrange on striker body slow
Flushing device, buffer unit can slow down the impulsive force that described coupler hook body brings when teeter, thus carry
The stability that high vehicle runs；Reduce the abrasion of hitch and striker, thus increase making of hitch and striker
Use the life-span.
For making the purpose of the application one embodiment, technical scheme and advantage clearer, below in conjunction with this Shen
Please accompanying drawing in embodiment, the technical scheme in the embodiment of the present application is clearly and completely described, aobvious
So, described embodiment is some embodiments of the present application rather than whole embodiments.Based on this Shen
Embodiment in please, the institute that those of ordinary skill in the art are obtained under not making creative work premise
There are other embodiments, broadly fall into the scope of protection of the invention.
For enabling those skilled in the art to understand the present invention in more detail, below in conjunction with accompanying drawing, the present invention is carried out
Describe in detail.
As it is shown in figure 1, a kind of railway freight-car striker that the embodiment of the present invention provides, with coupler hook body phase
Coordinating, described striker includes:
Striker body 1, the center of described striker body 1 is provided with places the accommodating logical of described coupler hook body 3
Road 11, the described striker body 1 of described holding channel 11 both sides is respectively equipped with a chamber resettling；Described
Striker body 1 is foundry goods；
Buffer unit 2, described buffer unit 2 is arranged in described chamber resettling, and described buffer unit 2 is close
One end of described holding channel 11 contacts with described coupler hook body 3；
Wherein, described buffer unit is for slowing down the impulsive force that described coupler hook body brings when teeter.
Further, as in figure 2 it is shown, described buffer unit 2 includes:
Buffer spring 21, described buffer spring 21 is arranged in described chamber resettling；
Top cover 22, described top cover 22 is done body 1 with described impact and is matched, by solid for described buffer spring 21
Being scheduled in the space of told top cover 22 and the formation of described chamber resettling, described buffer spring 21 one end is fixed on
On described striker body 1, the other end contacts with the inner side of described top cover 22, outside described top cover 22
Side contacts with described coupler hook body 3；
Wherein, described top cover 22 for making described buffer spring 21 when described coupler hook body 3 teeter
Compress the most laterally.
