Abstract

The disclosure provides a chassis component of a railway vehicle, and a railway vehicle, the chassis including two lower boundary beams, the two lower boundary beams being provided at an interval; and a cross beam component, the cross beam component being provided between the two lower boundary beams, wherein there are a plurality of cross beam components, and the plurality of cross beam components are provided along a length direction of each of the lower boundary beams at an interval, wherein at least one cross beam component includes a first cross beam and a second cross beam provided below the first cross beam in a height direction of the each of the lower boundary beams, the first cross beam and the second cross beam form a mounting cavity, and a part of a floor of a railway vehicle penetrates into the mounting cavity.

First claim

What is claimed is:

1. A chassis component of a railway vehicle, the chassis component comprising:
two spaced lower boundary beams ( 20 ); and
two spaced sleeper beams ( 10 ), provided between the two lower boundary beams ( 20 ) along a length direction of the lower boundary beams ( 20 ), at least one of the sleeper beams ( 10 ) comprising:
a web structure ( 14 );
a center pin ( 11 ), connected with a bogie of a railway vehicle; and
a mounting frame, connected with the web structure ( 14 ), the center pin ( 11 ) being provided on the mounting frame, the mounting frame comprising a plurality of vertical plates ( 12 ), and the plurality of vertical plates ( 12 ) being spaced along an outer wall surface of the center pin ( 11 ), the plurality of vertical plates ( 12 ) are provided on the outer wall surface of the center pin ( 11 ) in an X shape, each vertical plate ( 12 ) being welded to the outer wall surface of the center pin ( 11 ).

2. The chassis component as claimed in claim 1 , wherein the at least one of the sleeper beams ( 10 ) comprises two web structures ( 14 ), the mounting frame being located between the two web structures ( 14 ).

3. The chassis component as claimed in claim 2 , wherein the at least one of the sleeper beams ( 10 ) further comprises a plurality of rib plates ( 13 ), each of the web structures ( 14 ) comprises two spaced webs ( 141 ), and the plurality of rib plates ( 13 ) are provided between the two webs ( 141 ) at intervals.

4. The chassis component as claimed in claim 3 , wherein the web structure ( 14 ) is connected with at least one of the vertical plates ( 12 ) of the mounting frame through at least one of the plurality of rib plates ( 13 ).

5. The chassis component as claimed in claim 3 , wherein at least one rib plate ( 13 ) in the plurality of rib plates ( 13 ) is provided with a weight-reducing through hole ( 132 ).

6. The chassis component as claimed in claim 5 , wherein each of the webs ( 141 ) is provided with a wire passage hole ( 142 ).

7. The chassis component as claimed in claim 3 , wherein the at least one of the sleeper beams ( 10 ) further comprises an upper cover plate ( 15 ) covering the web ( 141 ), the upper cover plate ( 15 ) is provided with a plurality of through holes ( 151 ), at least one of the rib plates ( 13 ) is provided with a bulge ( 131 ), and the bulge ( 131 ) matches the corresponding through hole ( 151 ).

8. The chassis component as claimed in claim 7 , wherein the upper cover plate ( 15 ) is provided with a first penetration-out hole ( 152 ), and one end of the center pin ( 11 ) penetrates out of the first penetration-out hole ( 152 ).

9. The chassis component as claimed in claim 8 , wherein the at least one of the sleeper beams ( 10 ) further comprises a lower cover plate ( 16 ) provided at a lower part of the two webs ( 141 ), the lower cover plate ( 16 ) being fixedly connected with each rib plate ( 13 ).

10. The chassis component as claimed in claim 9 , wherein the lower cover plate ( 16 ) is provided with a second penetration-out hole ( 161 ), and the other end of the center pin ( 11 ) penetrates out of the second penetration-out hole ( 161 ).

11. The chassis component as claimed in claim 3 , wherein the at least one of the sleeper beams ( 10 ) further comprises two spaced inner boundary beams ( 17 ), the two inner boundary beams ( 17 ) being in one-to-one corresponding connection with the two lower boundary beams ( 20 ).

12. The chassis component as claimed in claim 11 , wherein each of the inner boundary beams ( 17 ) is connected with the two webs ( 141 ) of at least one of the web structures ( 14 ).

13. The chassis component as claimed in claim 4 , wherein each of the sleeper beams ( 10 ) further comprises two spaced inner boundary beams ( 17 ), the two inner boundary beams ( 17 ) being in one-to-one corresponding connection with the two lower boundary beams ( 20 ).

14. The chassis component as claimed in claim 5 , wherein each of the sleeper beams ( 10 ) further comprises two spaced inner boundary beams ( 17 ), the two inner boundary beams ( 17 ) being in one-to-one corresponding connection with the two lower boundary beams ( 20 ).

15. The chassis component as claimed in claim 6 , wherein each of the sleeper beams ( 10 ) further comprises two spaced inner boundary beams ( 17 ), the two inner boundary beams ( 17 ) being in one-to-one corresponding connection with the two lower boundary beams ( 20 ).

16. The chassis component as claimed in claim 7 , wherein each of the sleeper beams ( 10 ) further comprises two spaced inner boundary beams ( 17 ), the two inner boundary beams ( 17 ) being in one-to-one corresponding connection with the two lower boundary beams ( 20 ).

17. The chassis component as claimed in claim 8 , wherein each of the sleeper beams ( 10 ) further comprises two spaced inner boundary beams ( 17 ), the two inner boundary beams ( 17 ) being in one-to-one corresponding connection with the two lower boundary beams ( 20 ).

18. A railway vehicle, comprising a vehicle body structure and a chassis component connected with the vehicle body structure, wherein the chassis component is the chassis component as claimed in claim 1 .
