Abstract
The invention discloses a kind of framework section bar attachment structure, including at least side with the hollow material of chute, described chute two side roof part is provided inwardly with hook, and hook forms groove with chute inwall intersection；The slide block of the W shape that also include connector, can slide in chute, is provided with screw in the middle part of described slide block, slide block both sides are adjacent to groove and engage, and connector is connected with the screw of slide block.The present invention application by combinative structure, replaces welding or riveting so that bonding strength will not decline, and maintenance or the replacing of parts are simple, are not susceptible to corrosion, do not destroy the integrity of section bar, is beneficial to produce the rapid transition with vehicle in enormous quantities.
Description
Technical field
The invention belongs to a kind of framework section bar attachment structure.
Background technology
During modern bus produces, aluminum body frame is gradually adopted to carry out loss of weight, to meet the light-weighted requirement of passenger vehicle.Aluminum closes
The connected mode of gold framework section bar is generally welded, rivets and is spirally connected.
In Chinese patent CN102815338A, disclose a kind of body frame entirety and use aluminum alloy materials to be welded
Vehicle body framework construction, the advantage of this kind of connected mode is to save material, reduce tare, but owing to aluminium section bar welding can shape
Become heat affected area to cause bonding strength to reduce, and welding structure is not easy to maintenance and the replacing of parts.
Chinese patent CN102211615A discloses a kind of structure connected mode by L-shaped aluminum corner brace Yu riveting transverse beam, should
Structure needs to punch in advance on section bar, the integrity that destroys section bar, the use intensity reducing material, rivet/spiral shell simultaneously
Silk directly contacts with section bar and easily comes in contact corrosion, thus reduces the service life of material.The make pair it addition, punch in advance
Loading precision requires height, is unfavorable for the fast transition of vehicle.
Along with transit trip mode is popularized energetically and promoted by country, the demand of passenger vehicle is increasing.And lead to
Normal body frame structure connected mode is difficult to meet the requirement that passenger vehicle is produced in enormous quantities and vehicle changes rapidly.
Summary of the invention
For the problems referred to above, it is desirable to provide the maintenance high, parts of a kind of bonding strength fall is changed conveniently, is difficult to send out
The framework section bar attachment structure that raw burn into is easy to connect.
The present invention solves the technical scheme of problem: a kind of framework section bar attachment structure, including at least side with chute
Hollow material, described chute two side roof part is provided inwardly with hook, and hook forms groove with chute inwall intersection；
The slide block of the W shape that also include connector, can slide in chute, is provided with screw, slide block both sides and ditch in the middle part of described slide block
Groove is adjacent to and engages, and connector is connected with the screw of slide block.
In such scheme, hollow material is connected by bolted mode, it is to avoid welding stress, corrosion etc. lack
Falling into, mounting structure is simple, it is easy to safeguard.
Described connecting-piece structure form has multiple, between two hollow materials connected as required relative to position not
With, the bending aluminium sheet of optional different angles is as connector.Such as, it is vertical between two hollow materials needing connection
During relation, optional L-type aluminum corner brace is as connector.
Further, the outer surface of described section bar has toothed surface, to increase the friction of section bar and skin, and more conducively two
The laminating of person.
Preferably, the tip of described hook is stretched out obliquely, and the angle between trenched side-wall is less than 90 degree；
The slide block of described W shape is provided with groove, the lowest part laminating of the tip of hook and groove.Purpose is to make slide block permissible
Preferably be nested in chute, particularly when bolt tighten, slide block by tightening force produce elastic deformation time can preferably prevent
Slide block is deviate from from chute.
The remarkable result of the present invention is:
1., by the application of combinative structure, replace welding or riveting so that bonding strength will not decline, and does not destroy the complete of section bar
Property, it is beneficial to produce in enormous quantities and the rapid transition of vehicle.
2. directly not contacting with section bar due to bolt, section bar itself is difficult to get rusty, and antirust, rust cleaning puts into and reduces.
3. after losing efficacy, can realize the quick-replaceable of trouble unit, change and be easier to, the recovery of trouble unit is more thorough
The end, reach the requirement of energy-conserving and environment-protective.
4. body frame section bar is connected by connector and slide block, it is achieved that the partial thickening of section bar junction, enhances
The entirety of the bonding strength of section bar, beneficially section bar is thinning, is proven section bar thickness and can reduce to 3 millimeters, has reached in the industry
The limit thought.
And, with bolts, there is a tensile force in advance, when vehicle body shakes, good compared with the shock resistance of riveting.
5. having abandoned the medium-and-large-sized welding equipment of welding manner, investment, production cost reduce, and assembly technical requirement declines.

Detailed description of the invention
As shown in figures 1-4, a kind of framework section bar attachment structure, including both sides with the hollow material 1 of chute 2, described type
The outer surface of material 1 has toothed surface 4.
2 liang of side roof parts of described chute are provided inwardly with hook 5, and hook 5 forms groove 3 with chute 2 inwall intersection.
The slide block 6 of the W shape that also include connector 8, can slide in chute 2.It is provided with screw 7, slide block in the middle part of described slide block 6
6 both sides are adjacent to groove 3 and engage, and connector 8 is connected with the screw 7 of slide block 6.
The tip 51 of described hook 5 is stretched out obliquely, and the angle between groove 3 sidewall is less than 90 degree.
The slide block 6 of described W shape is provided with groove 61, fits with the lowest part of groove 61 in the tip 51 of hook 5.
Described connector 8 version has multiple, between two hollow materials 1 connected as required relative to position not
With, the bending aluminium sheet of optional different angles is as connector.Such as, when need connect two hollow materials 1 between be
During vertical relation, optional L-type aluminum corner brace is as connector.
The structure of described section bar 1 also can make the change approximated, as it is shown in figure 5, according to real needs, can be only at side band
There is chute 2.
The connection of section bar is by putting in chute 2 by slide block 6, is then affixed on by connector 8 outside the chute 2 of two section bars 1
End, finally by bolt by fixing tight to slide block 6 and connector 8.
Owing to during assembling, slide block 6 in chute 2 slidably can be deacclimatized the fixed position of connector 8, therefore assemble
Flexibly, mounting technology difficulty is little, efficiency of assembling is high, the most beneficially the rapid conversion of vehicle.It addition, when after component malfunction,
The convenient maintenance of vehicle body can be realized by the way of demounting bolt, replacing parts.
