[detailed description of the invention]
For the ease of understanding the present invention, the present invention will be described more fully below.But, the present invention can be to be permitted
The most different forms realizes, however it is not limited to embodiment described herein.On the contrary, providing the purpose of these embodiments is to make
Understanding to the disclosure is more thorough comprehensively.
Shown in reference Fig. 1-Fig. 4, a kind of frame beam structure that the present invention provides, including two parallel main longitudinal griders 1, vertically
Connect some main beams (not shown) of main longitudinal grider, two parallel support stringers 2 described in two, be connected to support stringer 2 described in two
The buttress brace 3 of rear end and the some support crossbeams 5 being parallel to each other with described buttress brace 3.Wherein, the two ends of described main beam are divided
Lian Jie not fix main longitudinal grider 1 described in two, and along the longitudinally arrangement of described main longitudinal grider 1.Described support crossbeam 2 is positioned at described in two
Between main longitudinal grider 1.
On the longitudinally of described main longitudinal grider 1, described main longitudinal grider 1 is divided into front-axle beam 11, oblique from the rear end of described front-axle beam 11
Bending downwards extends the tie-beam 12 formed and from the back rest 13 of the horizontal-extending formation in rear end of described tie-beam 12.Before described
Beam 11 is parallel to each other with the back rest 13, and the end face of described front-axle beam 11 is positioned at the top of the end face of the described back rest 13 and both spacing are big
In 300mm.
Described support stringer 2 is set up on the described main beam connecting described front-axle beam 11, and the rear end of described support stringer 2
Extending outside described front-axle beam 11, described support stringer 2 is mutually perpendicular to described main beam.
Described buttress brace 3 is mutually perpendicular to described support stringer 2, and the bottom shelf of described buttress brace 3 is located at the described back rest 13
On, described support stringer 2, buttress brace 3 and the back rest 13 entirety are one step-like.
Described support crossbeam 5 is set up on the described back rest 13, described support crossbeam 5 be positioned at described buttress brace 3 away from institute
State the side of support stringer 2 and along the longitudinally parallel arrangement of the described back rest 13.
With reference to shown in Fig. 1, described support stringer 2 is connected and fixed on the bottom of envelope front floor 41, in order to described support
Envelope front floor 41.Described support crossbeam 5 is connected and fixed on the bottom of envelope heel slab 42, after supporting described envelope
Portion's base plate 42.Described buttress brace 3 side is connected and fixed on the rear end of support stringer 2 described in two, after opposite side connects fixing envelope
Portion, described buttress brace 3 top is connected and fixed on the bottom of described envelope front floor 41, thus in step-like support stringer 2,
Buttress brace 3 and the back rest 13 form firm support to the envelope after improving.Receiving area 40 is then to increase after envelope improves
The part of article containing space.
The present invention provides frame beam structure, and the bending of main longitudinal grider reaches more than 300mm, adaptive improve after with the level
Envelope；The support level of support stringer, buttress brace, back rest composition, forms firm support to the envelope with the level after improving；Main
Longeron is continuous structure, and middle free of discontinuities, intensity is high；In the case of total height is constant, envelope volume can be made to increase, can be adaptive
Envelope with the level after improvement and guarantee frame strength.
In present embodiment, described buttress brace 3 includes strengthening upper beam 31 and being fixed on adding bottom described reinforcement upper beam 31
Strong underbeam 32.The two ends of described reinforcement upper beam 31 connect respectively fixes the rear end of support stringer 2 described in two, described reinforcement underbeam 32
Bottom shelf be located on the described back rest 13.Thus, the reinforcement upper beam of small cross-sectional size specification, reinforcement underbeam can be beneficial to existing mold
And frock carries out mass production, comparing buttress brace global formation, it is not necessary to additionally offer mould, cost puts into low, intensity not
Reduce.
In present embodiment, more specifically, described reinforcement upper beam 31 and reinforcement underbeam 32 are square metal tube.By
This, it can be ensured that strengthen upper beam and strengthen underbeam and support stringer and the connection fixed effect of envelope.
In present embodiment, in the vertical direction, described main longitudinal grider 1 includes upper flange 101, is set in parallel in described upper limb
Lower wing plate 103 immediately below plate 101 and the vertical web 102 connecting described upper flange 101 and lower wing plate 103.With reference to Fig. 4 institute
Showing, the cross section of described main longitudinal grider 1 is I-shaped.Thus, main longitudinal grider is that whole frame beam structure provides basis well
Support effect, and improve the intensity of whole vehicle frame.
In present embodiment, more specifically, the bottom surface of described upper flange 101 is convexly equipped with downwards accepting groove 104, described
The end face of lower wing plate 103 is convex is provided with lower accepting groove 105.Top and the bottom of described web 102 are divided by the way of full weld
It is not fixed in described upper accepting groove 104 and lower accepting groove 105.Thus, upper flange, lower wing plate, web connection the most firm,
The service life of main longitudinal grider is longer.
In present embodiment, more specifically, described upper flange 101, web 102 and lower wing plate 103 are all integrated into
Type.Thus, both it had been easy to shape extrusion, had improved again the structural strength of main longitudinal grider.
In present embodiment, described support stringer 2 with support crossbeam 5 cross section all in I-shaped.Thus, both reduce
Material cost, provides again good support strength.
In present embodiment, described frame beam structure is made up of aluminium alloy.Thus, the weight of vehicle frame is reduced, simultaneously
Ensure that the intensity of vehicle frame, with aluminum envelope adaptation while, reduce further the overall weight of railway carriage or compartment car.
Compared with correlation technique, the present invention mainly has the beneficial effects that, envelope after adaptive adjusting and guarantee vehicle frame
Intensity.
Above-described is only embodiments of the present invention, it should be noted here that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, it is also possible to make improvement, but these belong to the protection model of the present invention
Enclose.
