Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model, below in conjunction with accompanying drawing pair
The utility model is further detailed.
See shown in Fig. 2-8, a kind of cantalever tube beam fixed structure providing for the utility model embodiment, including vehicle frame 1
With pipe beam 2, wherein, this programme improvement is, by the mounting bracket of integral type before, to make two parts into, it is to avoid one piece rigid
Connecting, anti-seismic performance is poor, causes the problem that pipe beam root easily occurs fracture.Specifically, the present embodiment uses fixing pipe 3 and peace
Dress support 4 realizes the fixing of pipe beam 2 root；Wherein, fix the root that pipe 3 is sleeved on pipe beam 2, then can weld realization further
Fixing pipe 3 closely cooperates with pipe beam 2, and the both sides of fixing pipe 3 are extended outward horizontally so as to form two first installing plates 5 respectively；Install
The side of support 4 is fixed on vehicle frame 1, and the opposite side of mounting bracket 4 is connected with two first installing plate 5 levels by bolt 8, its
In, mounting bracket 4 can use common structure, and such as horizontal vertical structure stand, i.e. vertical section are fixed on vehicle frame, and horizontal segment is respectively
It is connected with two first installing plate bolts.The present embodiment uses fixing pipe, mounting bracket two parts to realize that Guan Liang's is fixing, and two
Part is with bolts, and certain pooling feature can be played in junction, can be prevented effectively from the fracture of root of Guan Liang.
In order to ensure the reliability that fixing tube and tube beam connects, in conjunction with shown in Fig. 7, Fig. 8, fixing pipe 3 in this programme by
Symmetrical two parts are opposed installs composition, the first installing plate 5 that each several part all includes a semi-circular tube with the both sides being located at semi-circular tube,
Multiple first installing hole 51 is offered on described first installing plate 5.During assembling, two halves pipe welds with pipe beam 2 respectively, uses spiral shell
Bolt 8 is connected with mounting bracket 4 after sequentially passing through the first installing hole 51 of fixing pipe 3 both sides.
Mounting bracket 4 in such scheme, when design, should be descended to ensure mounting bracket in the situation saving material as far as possible
Intensity, in conjunction with shown in Fig. 2-6, mounting bracket 4 in the present embodiment, further with improvement, comprising: the gusseted plate of both sides
41, the top of two triangle gripper shoes 41 is connected by a plate 42；The bottom of two triangle gripper shoes 41 all horizontally outward extends
Having the second installing plate 43, the first installing plate 5 is just arranged by the second installing plate 43, on each second installing plate 43 offer respectively multiple
Second installing hole 44；Bolt 8 is connected with a nut 6 after sequentially passing through the first installing hole the 51st, the second installing hole 44, it is achieved installs and props up
Frame 4 and the connection of fixing pipe 3, namely achieve the fixing of pipe beam 2 root.When fixing with vehicle frame 1, can directly weld or second
Installing plate 43 is just being bent to form downwards bracket fixture portions 45, wherein, bracket fixture portions 45 and described connecting plate to the side of vehicle frame 1
42 is coplanar, and bracket fixture portions 45 all offers multiple fixing hole on described connecting plate 42.When being connected fixing with vehicle frame, use
Bolt realizes, this fixed solution facilitates the dismounting of mounting bracket 4.
Wherein, between the first installing plate 5 and the second installing plate 43, also can set up guide pipe 7, in order to the installation of bolt 8 with
And reduce the stress of bolt 8.Wherein, guide pipe 7 is fixed on the bottom of the first installing plate 5, and just arranges the first installing hole 51.
Fixing employing bolt pattern employing flexible connected between pipe 3 and mounting bracket 4, for improving bolt 8 life-span, usually
Reduce bolt 8 rigidity, can reach to reduce the maximum of bolt 8 total pulling force, i.e. reduce the purpose of stress amplitude, thus improve bolt
8 life-spans.For reducing bolt 8 rigidity, can suitably increase the length of bolt 8.Or use waisted bar bolt or hollow bolt, or at spiral shell
Female flexible member installed below, such as elastomeric pad, as shown in Figure 6, during installation, with nut 6 against employing bullet bottom elastomeric pad
Property pad, reduce stress at bolt, improve the life-span of bolt further.
In sum: pipe beam root stress is big and frequent vibration, uses this attachment structure form, and position easy to crack is by Guan Liang
Being transferred at root run at bolt, the life-span of whole pipe beam assembly is guaranteed, and can avoid pipe beam fracture of root, improve pipe
The life-span of beam assembly；Even if it the bolt fracture of easy fracture, is easily replaced, and replacement cost is low；Bolt is used to flexibly connect, can
It is prevented effectively from cantilever beam fracture；Meanwhile, the structure of mounting bracket, has some strength and rigidity, can improve spiral shell to a certain extent
The bolt life-span.
By way of explanation, only describe some one exemplary embodiment of the present utility model above, undoubtedly, for
Those of ordinary skill in the art, in the case of without departing from spirit and scope of the present utility model, can be with various different
