Sum it up, the present invention is that the structural member quality that the vehicle frame of existing car launcher is present is larger, vehicle barycenter to solve
It is higher, the problem of partial structurtes power stream transitivity is poor there is provided a kind of layer-stepping vehicle frame for car launcher.By using big
The mode that type rectangular tube bottom frame assembly is combined with truss structure, has both participated in unitized frame and comes from frame interior and outer
The various complex loads on boundary, will bend, turn round stretching and compression stress that the load transfer such as anti-is rod member, improve vehicle frame to external world
The attraction power of load, overcomes the defect of local force stream diversity difference.
It is main based on rectangle mount structure in bottom frame assembly 1, will not occur diamonding.In bottom frame assembly 1
Most vertical load in bullet/arrow and each assembly is assume responsibility for by the mechanical characteristic of heavy in section rectangle pipe material, while in bullet/arrow
Rise it is perpendicular during relatively big load at Erecting organ lower fulcrum has been evacuated by the arrangement of rod member.Installation place is hung to carry as the external world
Lotus enters the access point of vehicle frame, by left top layer frame assembly 3 and right top layer frame assembly 4 and left buttress brace 34 and right buttress brace
44 realize the scattered of power stream, it is to avoid defect of the load concentration at the hanger of suspension crossbeam 27.Installed in after-poppet assembly 7
Play perpendicular relevant pivoting support with bullet/arrow, rise it is perpendicular during, pass to the load of vehicle frame by pivoting support, it is total through after-poppet
Longeron 73 and second time raker beam 78 of longeron 76 and the 4th realize the evacuation of power stream on into first in 7.By in middle level bone
The both sides of frame assembly 2 construct the cargo space of sufficiently large installation equipment, can make in the prior art loaded on each at the top of vehicle frame
Equipment is loaded in cargo space by its functional requirement, reduces barycenter.The particularity that middle level frame assembly 2 is installed according to bullet/arrow,
U-shaped space is formd by reasonable Arrangement support post 24 and suspension column 25, coordinates the 3rd raker beam 29 of both sides, disperses
Bullet/arrow load, improves the uniform force of vehicle frame rod member.As can be seen here, the present invention is the car launcher for being equipped with compound energy,
Enough cargo holds and bullet/arrow installing space are designed in vehicle body frame structure, it is ensured that each assembly, which installs rear, relatively low barycenter.
The loading and size born according to vehicle frame different parts, by using the rod member of different specification size, realizes vehicle frame
Structure lightened purpose.In actual applications, bottom frame assembly 1 is primarily subjected to bending and torsional load, generally uses
160*60*8mm rod member, to lift its bending strength and torsional rigidity.Middle level frame assembly 2 is mainly undertaken from bullet/arrow
Vertical load, generally using 100*60*5mm rod member, and passes through support post 24 and suspension column 25 and bottom frame assembly
1st, left top layer frame assembly 3 and right top layer frame assembly 4 are rigidly connected, it is ensured that the uniformity of vehicle frame integrated carrying.It is left
Main load of the carrying from suspension of top layer frame assembly 3 and right top layer frame assembly 4, at the same be also subjected to a small amount of bending and
Torsional load, left buttress brace 34 and right buttress brace 44 are using 80*60*6mm rod member, and the 3rd lateral connection beam the 31, the 3rd is left to be indulged
To the right longitudinally connected beam 33 of tie-beam the 32, the 3rd, the right longitudinal direction of left longitudinally connected beam 42 and the 4th of the 4th lateral connection beam the 41, the 4th
Tie-beam 43 uses 80*60*3mm rod member.As can be seen here, the present invention is meeting intensity by improving tubing specification
And under the requirement of rigidity, realize the lightweight purpose of vehicle frame.Bottom frame assembly 1 and middle level frame assembly 2 are set by correspondence
The first raker beam 16 and the second raker beam 28 are put, the first-order modal frequency of vehicle frame is greatly improved, it is ensured that vehicle frame has foot
Enough antitorque allowances.As can be seen here, the present invention is by improving modal frequency numerical value, it is to avoid resonate.
Above example is only the description carried out to the preferred embodiment of the present invention, and model not is claimed to the present invention
Enclose and be defined, on the premise of design spirit of the present invention is not departed from, technology of this area engineers and technicians according to the present invention
In the various forms of deformations that scheme is made, the protection domain that claims of the present invention determination all should be fallen into.
