Sufficient passenger comfort requirement.In addition, the frame structure for resisting snakelike damper base 13, first crossbeam 12, sleeper beam 10 and side bar 5 to form
The longitudinal force of train can be transmitted, vertical force when vehicle carries out trolley operation by damper base can be also transmitted, improve rail
The structural stability of road vehicle.
Referring to Figure 1, the setting table vehicle seat 14 on resisting snakelike damper base 13.In turn, snakelike shock absorber bearing is resisted not only may be used
Resist snakelike damper to play the role of installing bogie, is also equipped with the function of lift vehicle.Also, for from structure, anti-snake
The frame that shape damper base 13, sleeper beam 10, side bar 5 and first crossbeam 12 form, can be improved chassis of rail vehicle or even vehicle
The longitudinal strength and overall stiffness of body.
It should be noted that only giving the structure of wherein one end of chassis of rail vehicle in Fig. 1.Under normal circumstances, rail
Road floor underframe for vehicle two-end structure is identical and is to be symmetrical arranged on the car body, therefore chassis of rail vehicle is omitted here
The structure of the other end.That is, sleeper beam 10 also can be set in the other end in chassis of rail vehicle, and sleeper beam 10 connects one group and resists
Snakelike damper base 13." one group resists snakelike damper base 13 " herein resists snakelike damper base 13 including at least two, and divides
The inside of two side bars 5 is not set.
One of embodiment according to the present utility model resists the alien invasion of snakelike damper base 13 and the interior of side bar 5 to stand
It is fixed between face.In addition, first crossbeam 12 and resisting can weld between snakelike shock absorber bearing.
In Fig. 2, the longitudinal section of side bar 5 is up gradually reduced from middle part, and the longitudinal section of side bar 5 gradually subtracts down from middle part
It is small.That is, the maximum longitudinal section of side bar 5 is formed in the intermediate altitude of side bar 5.Wherein, the middle part of side bar 5 is its opposite upside
With for the downside namely middle part of side bar 5 can be along in short transverse closer to the position of the upside of side bar 5, can also
Be along in short transverse closer to the position of the downside of side bar 5.
Wherein, specific location stress according to suffered by it of the maximum longitudinal section of side bar 5 is designed.It is corresponding at maximum stress
The maximum longitudinal section of side bar 5.Also, the plane for being perpendicular to paper that " longitudinal section of side bar 5 " refers to intercepts obtained by side bar 5
Plane.
One of embodiment according to the present utility model, side bar 5 connect lower floor 8 by rounding off structure 9.
In the case of this kind, when chassis of rail vehicle is installed to vehicle body of railway vehicle, entire rail vehicle can be promoted
Stability, influence of the beam wind to vehicle is effectively reduced.
In Fig. 3, towards the direction close to the lower floor 8, the longitudinal section of rounding off structure 9 is gradually reduced.This kind
In the case of, while controlling the weight of rail vehicle, it is ensured that the structural strength of rail vehicle.
One of embodiment according to the present utility model, chassis of rail vehicle pass through the double-deck profile using the double-deck profile
Use, it is ensured that the structural strength of chassis of rail vehicle, and can to chassis of rail vehicle carry out variable cross-section design.
One of embodiment according to the present utility model, in side bar 5, lower floor 8 and rounding off structure 9 extremely
It is one of few to be prepared using aluminium alloy extrusions, including double-layer aluminium alloy plate, and be arranged between double-layer aluminium alloy plate

Intensity.Also, since stress is different at chassis of rail vehicle different location, and then can also be according to suffered stress design reinforcing rib
Distribution.
In Fig. 2, lower floor 8 includes upper layer aluminium alloy plate and lower layer's aluminium alloy plate.
Wherein, since the distance from bottom ground of lower layer's aluminium alloy plate is closer, meeting when rubble or gravel on track fly up
The bottom of lower layer's aluminium alloy plate is caused to impact.Also, external environment is also easier to cause the bottom of lower layer's aluminium alloy plate
It influences, such as rainwater will lead to the bottom corrosion of lower layer's aluminium alloy plate.Therefore, the bottom of lower layer's aluminium alloy plate is provided with anti-corrosion
Wearing layer.
In addition, acoustic material, coldproof material and damping material are arranged between upper layer aluminium alloy plate and lower layer's aluminium alloy plate
One or more of when.
One of embodiment according to the present utility model provides a kind of vehicle body of railway vehicle, including side wall and above-mentioned rail
Road floor underframe for vehicle.Wherein, middle layer floor 2 is provided with above lower floor 8, the lower section on middle layer floor 2 is provided with second cross beam 3.
This kind of vehicle body of railway vehicle, vehicle body are divided into upper layer guest room 1 and lower layer guest room 4, upper layer from middle layer floor 2
Seat or sleeping berth can be respectively set in guest room 1 and lower layer guest room 4, and then can greatly improve the conevying efficiency of rail vehicle.
Further, since the lower section on floor 2 is provided with second cross beam 3 in middle level, and then upper layer guest room 1 and lower layer guest room 4 can be improved
Bearing capacity guarantees the structural strength of vehicle body of railway vehicle.
Wherein, middle layer floor 2 is for bearing 1 all devices of upper layer guest room and the vertical load of personnel, in middle level under floor 2
Side's setting second cross beam 3, increases the rigidity on middle layer floor 2 and the stability of track vehicle body structure.Further, pass through
Second cross beam 3 is set, improves the stiffness and strength in upper layer and lower layer space, it is not set to reduce chassis of rail vehicle sunk area
Risk brought by crossbeam.
One of embodiment according to the present utility model, side bar 5 and side wall and side bar 5 and rounding off structure 9 it
Between grafting.
Fig. 4 is referred to, passes through the first connector and the second connector grafting between side bar 5 and side wall.Wherein, the first connector includes
Backwards to the first grab 6 of setting, the second connector includes the second grab 7 being oppositely arranged, the first grab 6 protrude into the second grab 7 it
Between and with the second grab 7 be clamped.By the cooperation of grab (the first grab 6 and the second grab 7), in addition to may be implemented side bar 5 with
The connection of side wall can also avoid forming protrusion between car side and side bar 5, guarantee vehicle body of railway vehicle interior surface
Planarization.
Wherein, it after the first grab 6 and the second grab 7 are clamped, is formed between the second grab 7 and the first joint body
Weld seam, and then can also further strengthen the bonding strength between side bar 5 and side wall by welding.
Rapid and convenient and reliable is assembled in the case of this kind, between side bar 5 and the other components of car body.
In Fig. 2, mounting platform is extended on the inside of side wall, middle layer floor 2 is overlapped on mounting platform and fixes.Wherein, pacify
Assembling platform includes overlap joint step, and the two sides on floor 2 are formed with the first overlap edge and the second overlap edge in middle level, and then pass through first
Overlap joint cooperation is formed between overlap edge and the second overlap edge and overlap joint step, that is, ensure that between mounting platform and middle layer floor 2
The rapidity of connection in turn ensures the reliability of junction between mounting platform and middle layer floor 2.
Certainly, the lap joint form between mounting platform and middle layer floor 2 has in very much, disclosed in any one prior art
Lap joint form can be applied in the utility model.
