Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in further detail with specific embodiment：
Embodiment one
As shown in figure 1, a kind of end wall structure of rail vehicle, including front end wall 1, energy absorbing component 2, rearward end frame 3, front end
Wall 1 and rearward end frame 3 are fixedly connected in the both sides of energy absorbing component 2 with energy absorbing component 2.
As shown in Figure 2 and Figure 5, front end wall 1 includes door pillar 4, end corner post 5, door entablature 6, end top bow 7, end wall panel
8th, pilot beam 9, end top bow 7 is fixedly connected with the top of door pillar 4 and end corner post 5, the two ends of door entablature 6 and the door of both sides
Column 4 is fixedly connected, and pilot beam 9 is fixedly connected with the bottom of door pillar 4 and end corner post 5, is thusly-formed the front end frame of closing.
End wall panel 8 is made up of top end wall panel 11 and bottom end wall panel 10, top end wall panel 11 and door entablature 6 and Men Li
It is fixedly connected between post 4, end top bow 7, is fixedly connected between bottom end wall panel 10 and door pillar 4, end corner post 5 and pilot beam 9,
The multiple bulging muscle of surface compression molding of top end wall panel 11 and bottom end wall panel 10 with strengthen rigidity, in top end wall panel 11
Meta installs column 12, strengthens the rigidity of top end wall panel 11, column 12 and end top bow 7, door entablature 6 and top headwall
It is fixedly connected between plate 11.
While end wall panel 8 is using drum gusset strengthen rigidity, the crossbeam between door pillar 4 and end corner post 5 is eliminated（In figure
Do not represent）, alleviate the weight of end wall structure.
As shown in Figure 4 and Figure 6, the section of pilot beam 9 is U-shaped, and its U-shaped opening is towards energy absorbing component 2, the U-shaped of pilot beam 9
The base of section is longer than top margin, due to hitch 9（Do not represent in figure）Effect, when car body is clashed into, the buffering of front end wall 1
The bearing capacity that beam 9 is born at first needed for Impact energy, therefore pilot beam 9 is higher, the rigidity of the section bar that pilot beam 9 is adopted and strong
Degree need to be bigger than other beam and columns of front end wall 1, or the beam and column of front end wall 1 is using the section bar with the same size of pilot beam 9.
As shown in Figure 3 and Figure 4, energy absorbing component 2 include several longitudinal beams, parallel longitudinal setting between each longitudinal beam,
Several longitudinal beams are fixedly connected with the edge of rearward end frame 3 and front end wall 1, and longitudinal beam includes top longeron 13, side girder
14th, bottom girder 15, push up longeron 13, side girder 14, bottom girder 15 by several certain lengths beam constitute, each longitudinal beam it
Between keep at a certain distance away.
Between the specification of longitudinal beam and each longitudinal beam the requirement according to client spaced apart by calculate and
The methods such as test determine, should both ensure can be realized under desired stroke speed to deform energy-absorbing, can have again certain intensity and
The weight of rigidity load-carrying skin 16 and whole front end wall 1.Thus the characteristic that energy absorbing component 2 passes through each longitudinal beam of change, such as
Spacing between form of fracture, wall thickness, length and each longitudinal beam, is adapted to the requirement of different energy absorptions, both may be used
Saving manufacturing cost again can compromise between security.
Because energy absorbing component 2 needs to be deformed energy absorption when clashing into, therefore the longitudinal beam of energy absorbing component 2 is adopted
Section bar ratio of rigidity front end wall 1 and rearward end frame 3 beam and column it is little, the section material section that longitudinal beam can be adopted be shaped as U-shaped,
Angular, box-shaped etc..
As shown in Figure 1 and Figure 4, rearward end frame 3 is to be fixedly connected shape by between top bow 17, heel post 18, sill 19
Into closed frame, the section bar that the beam and column of rearward end frame 3 is adopted will at least ensure itself and body framing（Do not represent in figure）
Intensity it is consistent, therefore top bow 17, heel post 18, the section of sill 19 are both preferably U-shaped.The section shape of rearward end frame 3
Shape and size are adapted with the shape and size of car body section.
As shown in figure 4, the U-shaped opening of sill 19 is towards energy absorbing component 2, the height of U-shaped opening is disconnected with bottom girder 15
Face is highly adapted.
Energy absorbing component 2 is fixedly connected to form integral frame structure with front end wall 1 and rearward end frame 3, vertical in energy absorbing component 2
It is fixedly connected with front end frame and rearward end frame 3 to beam, wherein fixed between top longeron 13 and end top bow 7 and top bow 17 connect
Connect；It is fixedly connected between side girder 14 and end corner post 5 and heel post 18；It is solid between bottom girder 15 and pilot beam 9 and sill 19
Fixed connection.
In 15 times setting side bars 20 of bottom girder, side bar 20 is the inverted trapezoidal structure of only one of which hypotenuse, and its inclined edge surfaces is backward
End frame 3, the top of side bar 20 is fixedly connected with bottom girder 15, and bottom is fixedly connected with the bottom of pilot beam 9, the He of bottom girder 15
The profile height sum of side bar 20 is highly adapted with the U-shaped opening of pilot beam 9, and the arrangement form of side bar 20 can be all
The bottom of bottom girder 15 is fixedly connected a side bar 20 or several bottom girders 15 and is fixedly connected with a side bar 20, and side bar 20 is water
Square to and perpendicular to bottom girder 15, it is also possible to be fixedly connected a side bar 20 in the bottom of each bottom girder 15.
Side bar 20 adopts skew wall towards one end of rearward end frame 3, is for energy absorbing component 2 and front end wall 1 and rearward end frame 3
Enclosed construction formed here after connection, it is to avoid the abrupt change of cross-section of bottom girder 15 and side bar 20 junction and cause bottom girder 15
The excessive situation of local stress, simultaneously because the profile size that pilot beam 9 is adopted is larger, the U-shaped opening of the section of pilot beam 9
Height is also higher, and the cross dimensions of bottom girder 15 is less than pilot beam 9, to connect pilot beam 9, bottom girder 15 and side bar 20
Globality afterwards more preferably, firmer, open by the profile height sum and the U-shaped of pilot beam 9 for preferably making bottom girder 15 and side bar 20
The height of mouth is adapted, and the base length of the channel section of pilot beam 9 is preferably identical with the base length of side bar 20, this
The mode of kind is also helped and for Impact energy to pass to body framing.
The outside of energy absorbing component 2 and side bar 20 in the integral frame structure for connecting arranges covering 16, and covering 16 is
One or several, covering 16 is fixedly connected with longitudinal beam and side bar 20, is fixedly connected between covering 16, and covering 16 is in longitudinal side
Two sides upwards are stretched out to front end frame and rearward end frame 3, solid between covering 16 and front end frame and rearward end frame 3
Fixed connection, forms end wall structure.
Mounted end wall structure is by rearward end frame 3 and body end portion（Do not represent in figure）Between connect, connected mode
It is fixedly connected using bolt, can quick dismounting and change after end wall structure is subjected to collision deformation.To ensure sealing, in back-end box
Fluid sealant is applied between frame 3 and body end portion.
Front end wall 1 and rearward end frame 3 make its surface more smooth using closed frame structure, with energy absorbing component 2 and car
Body end portion can be convenient when connecting, and the surface between more smooth rearward end frame 3 and body end portion can fit
More preferably, the better tightness between end wall structure and car body can be made.
To ensure the bulk strength of end wall structure, the connected mode in above-mentioned end wall structure between all parts is preferably adopted
With being welded to connect, the material of each part can be the body framing of the rail vehicles such as carbon steel, stainless steel, aluminium alloy in end wall structure
Conventional material.
