Abstract
The present invention proposes a kind of commercial vehicle longitudinal beam structure, the longitudinal beam is trench structure, double wrapped is integrated inside and outside point, the endothecium structure of the longitudinal beam is that aluminum alloy material forms girder, outer layer is steel structure, wherein the steel structure of outer layer is divided into the upper and lower gap Wai Liang again and is correspondingly arranged, and upper and lower outer beam bends inwards and section is L-shaped, and the endothecium structure of aluminum alloy material is wrapped up and pass through riveting and is integrated by the L-shaped structure of upper and lower outer beam.The form that the present invention is combined using steel aluminium is on the basis of meeting frame strength, reduce vehicle frame weight, main body material system of the aluminium alloy as longitudinal beam, beam outside steel is riveted on the outside of the stringer to improve the intensity of vehicle frame, and the girder thickness that the aluminum alloy material is formed is greater than the thickness of outer layer steel structure outer beam above and below；Because the density of aluminium alloy be 2.8g/cm3 be less than steel density be 7.85g/cm3, so stringer overall weight mitigate.
Description
Technical field
It is to longitudinal beam light-weight design structure, specifically a kind of commercial vehicle stringer the present invention relates to commercial vehicle stringer
Structure.
Background technique
Commercial vehicle mainly applies to cargo transport, and loading capacity is big, and applying working condition is complicated, and phenomenon of rupture easily occurs in vehicle frame；
It is all using increase vehicle frame thickness, the method increases vehicle frame weight, reduces vehicle charge material currently in order to improving frame assembly intensity
Amount.
With the fast development of technology, the requirement to commercial vehicle lightweight, reliability is higher and higher, it is desirable that vehicle frame have compared with
High intensity, at the same time it is wished that vehicle frame is light-weight.
Application number 201720908400.1 discloses a kind of aluminium alloy bicycle frame structure of new-energy automobile, can be convenient for group
Dress, and can enhance the fastness after assembling, has buffer capacity, can slowing down vibration power, structure is simple, easy to use, at
This is low.
Application number 201611257790.7 discloses a kind of Combined aluminum alloy vehicle frame of light truck, including main body of vehicle frame, electricity
Attachment device between pond group side hanging device and main body of vehicle frame and motor, main body of vehicle frame include the aluminium that two sections are I-shaped
The aluminum alloy cross beam of several section I-shapeds of two stringers of alloy stringer and connection.Vehicle frame light weight increases electronic
Automobile course continuation mileage.
Vehicle frame is made that in above-mentioned patent and the file having disclosed and is correspondingly improved, to reach different effects
Fruit, but just to need new structure that could use for commercial vehicle.
Summary of the invention
Capacity of vehicle is big, applying working condition is poor when the present invention is in order to solve commercial vehicle transport cargo, and vehicle frame is in use process
Easily there is fracture, bends phenomenon in middle carrying section；Lightweight structure design is carried out to commercial vehicle stringer, spy proposes that a kind of commercial vehicle is vertical
Girder construction.
Thus the technical scheme is that, a kind of commercial vehicle longitudinal beam structure, including longitudinal beam, the longitudinal beam
For trench structure, a point inside and outside double wrapped is integrated, it is characterised in that: the endothecium structure of the longitudinal beam is aluminum alloy material
Girder is formed, outer layer is steel structure, and wherein the steel structure of outer layer is divided into the upper and lower gap Wai Liang again and is correspondingly arranged, upper and lower outer
Beam bends inwards and section is L-shaped, and the endothecium structure of aluminum alloy material is wrapped up and passed through by the L-shaped structure of upper and lower outer beam
Riveting is integrated.
Further improvement is that the height of the upper outer beam middle front part is greater than the height at the upper rear portion Wai Liang, it is corresponding lower outer
The height at beam rear portion is greater than the height of lower outer beam middle front part.
Further improvement is that the aluminium alloy girder uses extrusion forming, top is circular arc, and with it is upper and lower outer
The circular arc of Liang Zhejiaochu is effectively bonded, and is formed main outer beam and is combined as a whole structure.
Further improvement is that the girder thickness that the aluminum alloy material is formed is outer above and below greater than outer layer steel structure
The thickness of beam.
The utility model has the advantages that
Stringer girder uses aluminum alloy material, stringer weight saving in the present invention；The outer beam of riveting steel on the outside of stringer girder simultaneously
The performance for efficiently using steel improves stringer integral strength；Outer beam is divided into two panels up and down, convenient for stringer synthesis assembly；Aluminium alloy master
Beam uses extrusion forming.
For outer beam is divided into upper and lower outer beam convenient for riveting, while upper and lower outer beam improves bending resistance to infolding, for convenient for zero
Part is installed, and outer depth of beam is big greatly, under rear portion for outer depth of beam on middle front part.
Aluminium alloy girder uses extrusion forming, at the top of circular arc be effectively bonded with circular arc at upper and lower outer beam dog-ear, formation
Main outer beam is combined as a whole structure, reasonable stress, while infolding raising integral bending.
The form that commercial vehicle frame carling structure of the present invention is combined using steel aluminium reduces on the basis of meeting frame strength
Vehicle frame weight, main body material system of the aluminium alloy as longitudinal beam rivet beam outside steel on the outside of stringer to improve the intensity of vehicle frame,
The girder thickness that the aluminum alloy material is formed is greater than the thickness of outer layer steel structure outer beam above and below；Because the density of aluminium alloy is
It is 7.85g/cm3 that 2.8g/cm3, which is less than steel density, so stringer overall weight mitigates.
