The present embodiment is to specific link position of the first crossbeam 12 on the first curb girder 11 and is not limited.Due to the first half frameworks 10
It is the main structure of bogie frame, bearing strength and stable tractive force transmittance process for guarantee bogie frame, first
The connection of curb girder 11 and first crossbeam 12, which can be, passes through welded connecting.Further, the first curb girder 11 and first crossbeam 12
Connection type and link position are equally applicable to the second curb girder 21 and second cross beam 22, no longer repeat one by one herein.
Further, the second end and first of the second end of first crossbeam 12 and the second curb girder 21 and second cross beam 22
Curb girder 11 is movable connection, so that between the second end of first crossbeam 12 and the second curb girder 21 and second cross beam 22
The junction of second end and the first curb girder 11 has to be extended along the first curb girder 11 and 21 length direction of the second curb girder, or perpendicular to the
The movable region that one curb girder 11 and 21 length direction of the second curb girder extend.
It should be noted that the middle part of the second end of first crossbeam 12 and the second curb girder 21 can be through fastener or can
Active connection connection, the middle part of the second end of second cross beam 22 and the first curb girder 11 are also possible to through fastener or movable
Connector connection, has the advantage that in this way: being the work for playing connection and transmitting load in locomotive car body based on bogie
With, when car body pass through irregularity or curved road when, the first curb girder 11 and second cross beam 22 and the second curb girder can be passed through
It is horizontal suitably to deform or adjust the first curb girder 11 and second in movable region for movable connection between 21 and first crossbeam 12
The direction of the connection angle of the connection angle of beam 22 and the second curb girder 21 and first crossbeam 12, deformation can be the first curb girder
11 and second curb girder 21 length direction, to make locomotive car body accommodation curve road.The direction of deformation can also be perpendicular to
The length direction of first curb girder 11 and the second curb girder 21 so that locomotive car body be made to adapt to concave-convex road surface, therefore guarantees steering structure
Frame has certain pliability, maintains the stabilization and support strength of car body.
As a kind of achievable embodiment, the end of the second end of first crossbeam 12 is equipped with the first swivel pin 121, the
The end of one swivel pin 121 is additionally provided with first node pressing plate 122, is provided in the outside wall surface of the second curb girder 21 hinged for first
The first mounting base 111 that pin 121 protrudes into.
First node pressing sleeve 112 is provided in first mounting base 111, the middle part of the first swivel pin 121 is threaded through first segment
In point pressing sleeve 112, first node pressing plate 122 moves inside first node pressing sleeve 112 for limiting the first swivel pin 121, with
The movable region of first crossbeam 12 is formed inside first node pressing sleeve 112.
It should be noted that the second end of first crossbeam 12 can with the first curb girder 11 referring to shown in attached drawing 6 and attached drawing 7
Flexible connection can be to be realized by articulated manner, and specific connection may is that the second end of first crossbeam 12 is provided with first
Swivel pin 121, the first swivel pin 121 is threaded through in first mounting base 111 at 21 middle part of the second curb girder, in the first mounting base 111
Portion is additionally provided with first node pressing sleeve 112, and the through-hole hingedly worn for first, the first hinge are offered in the middle part of first node pressing sleeve 112
Outbound 121 passes through 112 rear end of first node pressing sleeve and connects first node pressing plate 122, and first node pressing plate 122 limits first
Swivel pin 121 is only capable of moving inside first node pressing sleeve 112, and the end of first node pressing sleeve 112 is solid by fastening bolt 13
Fixed, moving direction can be with the center rotating of first node pressing sleeve 112, be also possible in horizontal, vertical or any angle side
It moves up, so that the movable connection between first crossbeam 12 and the second curb girder 21 is realized, so that bogie frame has
Pliability is to accommodation curve road or the traveling on uneven road surface.Further, first node pressing plate 122 and second node
Pressing sleeve 212 selects elastic component that the relative movement of first crossbeam 12 and the second curb girder 21 can be made to have certain elasticity fortune
The stress inside bogie frame is reduced to the greatest extent and is concentrated, steering structure is improved to adapt to deformation by a small margin in dynamic space
The bearing strength and service life of frame.
As a kind of achievable embodiment, the end of the second end of second cross beam 22 is equipped with the second swivel pin 221, the
The end of two swivel pins 221 is additionally provided with second node pressing plate 222, is provided in the outside wall surface of the first curb girder 11 hinged for second
The second mounting base 211 that pin 221 protrudes into.
Second node pressing sleeve 212 is provided in second mounting base 211, the middle part of the second swivel pin 221 is threaded through the second section
In point pressing sleeve 212, second node pressing plate 222 moves inside second node pressing sleeve 212 for limiting the second swivel pin 221, with
The movable region of second cross beam 22 is formed inside second node pressing sleeve 212.
It should be noted that referring to shown in attached drawing 7, the movable company of above-mentioned 12 second end of first crossbeam and the second curb girder 21
It connects mode and obtained technical effect is equally applicable to the second end of second cross beam 22 and the movable connection of the first curb girder 11,
And identical technical effect can be obtained, is no longer repeated one by one herein.
Further, the first curb girder 11 away from 12 side of first crossbeam and the second curb girder 21 deviates from second cross beam
22 sides are additionally provided at least one for installing braking flap seats 40 of brake assemblies, brake the end of flap seat 40 to bogie frame
Bottom extend.
Also, braking flap seat 40 is four, and four braking flap seats 40 are separately positioned on the horizontal away from first of the first curb girder 11
The both ends of 12 side of beam and the second curb girder 21 deviate from the both ends of 22 side of second cross beam.
Specifically, braking flap seat 40 include from top to bottom sequentially connected connector 41, be overlapped on connector 41 and plate
It two braking flap seat gussets 42 that face is oppositely arranged and is connected on two braking flap seat gussets 42 and plate face is opposite sets
The lower reinforcement plate 43 of two set.
The first braking flap seat mounting plate 44 having for brake assemblies installation is horizontally disposed between two braking flap seat gussets 42,
The second braking flap seat mounting plate 45 having for brake assemblies installation is horizontally disposed between two lower reinforcement plates 43, for making respectively
Brake assemblies are fixed in the two sides up and down of dynamic component.
It is arranged it should be noted that bogie frame provided in an embodiment of the present invention will brake flap seat 40 in the first curb girder 11
Deviate from 22 side of second cross beam away from 12 side of first crossbeam and the second curb girder 21, referring to shown in attached drawing 1 to attached drawing 3, braking
Flap seat 40 is the outside that the first curb girder 11 and the second curb girder 21 is arranged in, and is had the advantage that in this way, 11 He of the first curb girder
The outside installation space of second curb girder 21 is larger, convenient for braking 40 welding of flap seat and postwelding adjusting processing, is not only convenient for operating, also
Seam deformation be can be reduced to reduce the stress at weld seam concentration and concentrate, evenly distribute the effect being applied on bogie frame
Power, to improve the support strength of bogie frame.
It should be further noted that braking flap seat 40 provided in this embodiment is four, it is separately mounted to the first curb girder
