[0002] The present disclosure relates to a field of railway
vehicles, and in particular to a chassis component of a railway
vehicle, and a railway vehicle.
BACKGROUND
[0003] A chassis component which serves as a main bearing structure
of a vehicle body not only bears the weight of the vehicle body and
the weight of all devices in the vehicle, but also transfers a
traction force and a braking force as well as a complicated dynamic
stress. Therefore, the chassis component must have a sufficient
strength and the rigidity.
[0004] In a stainless steel vehicle body of the related art, the
chassis component includes two lower boundary beams and a plurality
of cross beams, the plurality of cross beams are provided along a
length direction of the lower boundary beam at an interval, a cross
section of each cross beam is of C-shaped, a metal floor covers the
cross beams and the lower boundary beams, the metal floor is
positioned above the cross beams and the lower boundary beams, and
an internal space of the vehicle is separated from an under-vehicle
device below the chassis component through the metal floor, so as
to achieve the effects of noise reduction and flame resistance.
However, due to a height limitation of the vehicle, when the floor
is paved above the cross beams and the lower boundary beams, the
internal space of the vehicle is limited accordingly, and the
mounting space requirements for a storage battery and other devices
cannot be met.
SUMMARY
[0005] Some embodiments of the present disclosure provide a chassis
component of a railway vehicle and a railway vehicle, intended to
solve the problem in the related art that an internal space of a
vehicle cannot be ensured on the premise of ensuring the connecting
strength between a cross beam and a floor.
[0006] To this end, some embodiments of the present disclosure
provide a chassis component of a railway vehicle. The chassis
component includes: a lower boundary beam, wherein there are 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 is 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 is into the mounting
cavity.
[0007] Some embodiments of the present disclosure provide a railway
vehicle. The railway vehicle includes a vehicle body structure and
a chassis component connected with the vehicle body structure, the
chassis component being the above chassis component.
[0008] By applying an embodiment of the present disclosure, the
cross beam component includes a first cross beam and a second cross
beam, the first cross beam and the second cross beam being provided
in sequence in the height direction of the lower boundary beam, so
that the first cross beam and the second cross beam are both
located in a space formed by the two lower boundary beams, and a
mounting cavity is formed between the first cross beam and the
second cross beam. Thus, when the floor is mounted in the mounting
cavity of the cross beam component, a height of an upper surface of
the floor is lower than a height of an upper surface of the each of
the lower boundary beams. Compared with the related art in which
the floor is directly paved above the cross beam, an embodiment of
the present disclosure enlarges the internal space of the vehicle
when ensuring that the height of the chassis component is not
increased. Further, the floor at least partially penetrates into
the mounting cavity, and the floor is sandwiched between the first
cross beam and the second cross beam, thereby improving the
mounting strength of the floor.

embodiments of the present disclosure, not all of the embodiments.
The following description of at least one exemplary embodiment is
only illustrative actually, and is not used as any limitation for
the present disclosure and the application or use thereof. On the
basis of the embodiments of the present disclosure, all other
embodiments obtained on the premise of no creative work of those of
ordinary skill in the art fall within the scope of protection of
the present disclosure.
[0019] It is to be noted that terms used herein only aim to

[0020] In some embodiments of the present disclosure, as shown in
FIG. 1, a length direction of a chassis component is an X
direction, and a width direction of the chassis component is a Y
direction.
[0021] As shown in FIG. 1 and FIG. 2, an embodiment of the present
disclosure provides a chassis component of a railway vehicle. The
chassis component includes a lower boundary beam 20 and a cross
beam component 40. There are two lower boundary beams 20, the two
lower boundary beams 20 being provided at an interval. The cross
beam component 40 is provided between the two lower boundary beams
20, there are a plurality of cross beam components 40, and the
plurality of cross beam components 40 are provided along a length
direction of each of the lower boundary beams 20, wherein at least
one cross beam component 40 includes a first cross beam 41 and a
second cross beam 42 provided below the first cross beam 41 in a
height direction of the each of the lower boundary beams 20, the
first cross beam 41 and the second cross beam 42 form a mounting
cavity, and a part of the floor 43 of the railway vehicle is
inserted into the mounting cavity.
[0022] In the present application, the cross beam component 40
includes a first cross beam 41 and a second cross beam 42, the
first cross beam 41 and the second cross beam 42 being provided in
sequence in the height direction of the each of the lower boundary
beams 20, so that the first cross beam 41 and the second cross beam
42 are both located in a space formed by the two lower boundary
beams 20, and a mounting cavity is formed between the first cross
beam 41 and the second cross beam 42. Thus, when the floor 43 is
mounted in the mounting cavity of the cross beam component 40, the
height of an upper surface of the floor 43 is lower than the height
of an upper surface of the each of the lower boundary beams 20.
Compared with the related art in which the floor is directly paved
above the cross beam, an embodiment of the present disclosure
enlarges the internal space of the vehicle when ensuring that the
height of the chassis component is not increased. In an exemplary
embodiment, at least a part of the floor 43 penetrates into the
mounting cavity, and the floor 43 is sandwiched between the first
cross beam 41 and the second cross beam 42, thereby improving the
mounting strength of the floor 43.
[0023] As shown in FIG. 2 and FIG. 3, in an embodiment of the
present disclosure, the first cross beam 41 includes a U-shaped
beam 411 and a connecting beam 412 connected with the U-shaped beam
411, the connecting beam 412 being connected with the floor 43.
[0024] In an exemplary embodiment, the U-shaped beam 411 includes
two opposite vertical segments and a horizontal segment connecting
the two vertical segments, wherein one of the two vertical segments
is connected with the connecting beam 412, and a height size of the
vertical segment is greater than a height size of the other
vertical segment.
[0025] By means of the arrangement, the strength of the U-shaped
beam 411 is good, and the strength requirements for the chassis
component of the railway vehicle are met. In an exemplary
embodiment, the connecting beam 412 is of a flat plate structure,
and the connecting beam 412 is in surface-to-surface contact with
the floor 43, so that the connecting strength between the first
cross beam 41 and the floor 43 is improved.
[0026] In an embodiment of the present disclosure, the U-shaped
beam 411 and the connecting beam 412 are connected together and
form a whole structure.
[0027] The arrangement ensures the overall strength of the first
cross beam 41, facilitates processing, and makes the integrity of
the first cross beam 41 good.
[0028] Of course, in an alternative embodiment not illustrated in
the present disclosure, the U-shaped beam 411 and the connecting
beam 412 may be separately provided, as long as the connecting
strength between the U-shaped beam 411 and the connecting beam 412
can be ensured.
[0029] As shown in FIG. 2 and FIG. 4, in an exemplary embodiment of
the present disclosure, the cross section of the second cross beam
42 is Z-shaped in the width direction of the chassis component.
[0030] The arrangement makes the strength of the second cross beam
42 high. Compared with the related art in which the cross beam is
usually C-shaped, the Z-shaped second cross beam 42 of an
embodiment of the present disclosure can better meet the strength
and rigidity requirements for the chassis component of the railway
vehicle.
[0031] As shown in FIG. 4, in an exemplary embodiment of the
present disclosure, the second cross beam 42 includes a first
horizontal beam 422, a vertical beam 423 and a second horizontal
beam 424 connected in sequence, the first horizontal beam 422 and
the second horizontal beam 424 are located on two sides of the
vertical beam 423 respectively, and the first horizontal beam 422
is connected with one side, away from the first cross beam 41, of
the floor 43.
[0032] In the embodiment, the first horizontal beam 422 and the
second horizontal beam 424 are provided on two sides of the
vertical beam 423, and a joint between the first horizontal beam
422 and the floor 43 is a surface-to-surface contact, so that the
connecting strength between the first horizontal beam 422 and the
floor 43 is better.
[0033] In an exemplary embodiment of the present disclosure, the
first horizontal beam 422, the vertical beam 423 and the second
horizontal beam 424 are connected together and form a whole
structure.
[0034] The arrangement ensures the overall strength of the first
cross beam 41, facilitates processing, and makes the integrity of
the first cross beam 41 good.
[0035] As shown in FIG. 4, in an exemplary embodiment of the
present disclosure, the second cross beam 42 is provided with a
wire passage groove 425, the wire passage groove 425 penetrating
through the second horizontal beam 424 and extending to the
vertical beam 423.
[0036] In an exemplary embodiment, a wire harness will pass through
a lower part of the chassis component. Since the second cross beam
42 is located below the floor 43 and the wire passage groove 425 is
provided on the second cross beam 42, the wire harness is
convenient to penetrate out of the wire passage groove 425, which
facilitates wiring of the railway vehicle and storage of the wire
harness. Further, the wire harness is received in the wire passage
groove 425, so that the wire harness is prevented from occupying a
space below the chassis component and ensuring the compact
structure and good integrity of the chassis component.
[0037] In an exemplary embodiment of the present disclosure, the
floor 43 is welded to the first cross beam 41, and the floor 43 is
welded to the second cross beam 42.
[0038] The arrangement ensures the connecting strength between the
floor 43 and the cross beam component 40, the connecting beam 412
of the first cross beam 41 is in surface-to-surface contact with
the floor 43, and the first horizontal beam 422 of the second cross
beam 42 is also in surface-to-surface contact with the floor 43,
thereby facilitating welding. In an exemplary embodiment, the floor
43 is sandwiched between the first cross beam 41 and the second
cross beam 42, the second cross beam 42 supports the floor 43, and
the floor 43 is firmly mounted.
[0039] In an exemplary embodiment of the present disclosure, the
floor 43 is a corrugated plate. The strength of the corrugated
plate is good, thereby ensuring the use strength of the floor
43.
[0040] As shown in FIG. 1, in an exemplary embodiment of the
present disclosure, two opposite ends of the first cross beam 41
correspond to the two lower boundary beams 20 respectively along a
width direction of the chassis component, and a distance between
the two ends of the first cross beam 41 is smaller than or equal to
a distance between the two lower boundary beams 20.
[0041] In an exemplary embodiment of the present disclosure, two
opposite ends of the first cross beam 41 are abut against the two
lower boundary beams 20 respectively. The arrangement ensures the
overall width of the chassis component, and the first cross beam 41
abuts against the two lower boundary beams 20. Not only the second
cross beam 42 supports the first cross beam 41, but also the lower
boundary beams 20 connected with the first cross beam 41 may also
support the first cross beam 41, so that the connecting strength
between the first cross beam 41 and each of the lower boundary
beams 20 is further ensured, and the structure and apparatus
provided at an upper part of the chassis component may be
effectively supported.
[0042] In an exemplary embodiment, an upper surface of the first
cross beam 41 is on a same plane with an upper surface of each of
the lower boundary beams 20.
[0043] The embodiment facilitates mounting of the device at the
upper part of the chassis component, the flatness is better, and
the device is steadily mounted. Further, the embodiment forms a
planar grid structure by the upper surface of the first cross beam
41 and the upper surface of the each of the lower boundary beams
20, the supporting strength is good, and the requirements for the
strength and rigidity of the chassis component are met.
[0044] The embodiment of the present disclosure also provides a
railway vehicle. The railway vehicle of the present embodiment
includes a vehicle body structure and a chassis component connected
with the vehicle body structure, the chassis component being the
above chassis component.
[0045] A mounting cavity is formed between the first cross beam 41
and the second cross beam 42 in some embodiments of the present
disclosure. Thus, when the floor 43 is mounted in the mounting
cavity of the cross beam component 40, the height of an upper
surface of the floor 43 is lower than the height of an upper
surface of the lower boundary beam 20. Compared with the related
art in which the floor is directly paved above the cross beam, some
embodiments of the present disclosure enlarges the internal space
of the vehicle when ensuring that the height of the chassis
component is not increased. In an exemplary embodiment, the floor
43 at least partially penetrates into the mounting cavity, and is
sandwiched between the first cross beam 41 and the second cross
beam 42, thereby improving the mounting strength of the floor 43.
Therefore, the railway vehicle having the above chassis component
also has the above advantages.
[0046] As shown in FIG. 5, a sectional view of mounting the floor
43 on the chassis component is shown. From FIG. 5, it can be
clearly seen that the height of the upper surface of the floor 43
is lower than the height of the upper surface of each of the lower
boundary beams 20 to form an embedded mounting structure. The
embodiment increases the internal space of the vehicle without
increasing the overall height of the chassis component.
[0047] The technical solution of the present application is
implemented by using the following mode: the cross beam component
of some embodiments includes a first cross beam 41 above and a
second cross beam 42 below. The floor 43 is sandwiched between the
first cross beam 41 and the second cross beam 42, and the floor 43
is located in a middle of the chassis component in the height
direction of the each of the lower boundary beams 20 and is a main
bearing structure of the entire railway vehicle. The floor 43 in an
embodiment is a metal corrugated plate, and the floor 43 is welded
to the first cross beam 41 and the second cross beam 42 in a
resistance spot welding manner. The joint between the floor 43 and
each of the lower boundary beams 20 on two sides is a folded edge
structure, the floor 43 and the each of the lower boundary beams 20
is connected into a whole by resistance spot welding, the first
cross beam 41 is welded to the each of the lower boundary beams 20
by L-shaped angle iron, and the second cross beam 42 is welded to
the each of the lower boundary beams 20 by L-shaped angle iron, so
as to complete assembling of the chassis component.
[0048] From the above description, it can be seen that the cross
beam component includes a first cross beam and a second cross beam,
the first cross beam and the second cross beam being provided in
sequence in the height direction of the each of the lower boundary
beams, so that the first cross beam and the second cross beam are
both located in a space formed by the two lower boundary beams, and
a mounting cavity is formed between the first cross beam and the
second cross beam. Thus, when the floor is mounted in the mounting
cavity of the cross beam component, the height of an upper surface
of the floor is lower than the height of an upper surface of the
each of the lower boundary beam. Compared with the related art in
which the floor is directly paved above the cross beam, the
embodiment enlarges the internal space of the vehicle when ensuring
that the height of the chassis component is not increased. Further,
the floor at least partially penetrates into the mounting cavity,
and the floor is sandwiched between the first cross beam and the
second cross beam, thereby improving the mounting strength of the
floor.
[0049] The above is only the preferred embodiments of the present
disclosure, not intended to limit the present disclosure. As will
occur to those skilled in the art, the present disclosure is
susceptible to various modifications and changes. Any
modifications, equivalent replacements, improvements and the like
made within the spirit and principle of the present disclosure
shall fall within the scope of protection of the present
disclosure.
