Description
Technical field
The utility model relates to trailer technical field, relates in particular to a kind of semi-trailer frame with special structure, and specifically a kind of lightweight semi-trailing car frame, is mainly used in unpowered vehicle.
Background technology
Superimposed trailer is a kind of own unpowered, with the common vehicle of tractor truck and cargo weight, and relies on tractor truck to draw the vehicle travelling.The advantages such as compared with " monomer-type " automobile, it is high that superimposed trailer has conveying efficiency, and the low and oil consumption of traffic cost is low, therefore the proportion in transport vehicle is constantly soaring.But existing superimposed trailer is because self structure design is unreasonable, cause weight excessive, adopt steel too much in producing, not only can increase productive costs, and can accelerate the wearing and tearing of the parts such as vehicle bridge, tire, improved use cost.In the time of the steel of the weight such as employing, charge capacity is often lower.In not affecting body construction intensity, reduce car body weight and become following developing direction.
Utility model content
The purpose of this utility model is to provide a kind of lightweight semi-trailing car frame, has fundamentally solved the problems such as existing semi-trailing car frame weight is large, low bearing capacity, tooling cost is high, processing technology is loaded down with trivial details.There is the advantages such as light weight, high capacity, low cost of manufacture.
The purpose of this utility model is achieved in that this lightweight semi-trailing car frame comprises the collar tie beam of rectangle, be arranged on the trailer coupling in collar tie beam, its technical essential is: in described collar tie beam, be welded with two that be parallel to each other and perpendicular to the wherein longeron of a pair of frame of collar tie beam, vertically run through longeron be equidistantly provided with some be parallel to each other be welded on the main beam on collar tie beam, main beam is W type beam, longeron is variable section structure, leading portion sectional area is less than back segment, longeron is by upper, lower wing plate and respectively with upper, the web that lower wing plate is vertical forms, trailer coupling is welded between the leading portion of two longerons, between the back segment of two longerons, be vertically welded with some secondary crossbeams, trailer coupling is the I-shaped structure of the vertical frame composition of the horizontal frame of traction and traction.
For enhancing productivity, improve vehicle frame stability, described web equal intervals is provided with the through hole matching with main beam.
For realizing best load-carrying capacity, reduce manufacturing cost, extend vehicle frame service life, described longeron is made up of Q960 shape steel plate.
The advantage the utlity model has and positive technique effect are: adopt W type beam as main beam, both reduced the weight of single-beam, improve again the bearing capacity of single-beam, thereby can in the situation that bearing capacity is identical, reduce vehicle frame overall weight, minimizing main beam quantity; Can, in the situation that total weight is certain, increase main beam quantity, improve bearing capacity.Main beam is equidistantly fixed in collar tie beam, has not only effectively shared the load of weight on vehicle frame, and can longeron be firmly fixed in collar tie beam by main beam.Longeron all adopts Q960 type structural steel and iron, because it has advantages of high strength, low weight, can in reducing weight, improve load-carrying capacity.Secondary crossbeam is set between longeron, further longeron is fixed.First weight on vehicle frame oppresses collar tie beam and longeron, and longeron is shared load on each main beam equally again, and because longeron has adopted high-intensity pressure-resistance structure steel plate, therefore can be on the basis that keeps configuration abundant share load.

Detailed description of the invention
Describe content of the present utility model in detail below in conjunction with Fig. 1 ~ 4.This lightweight semi-trailing car frame comprise rectangle collar tie beam 1, be arranged on the parts such as the trailer coupling 3 in collar tie beam 1.Wherein, in collar tie beam 1, be welded with two that be parallel to each other and perpendicular to collar tie beam 1 wherein the longeron 2(of a pair of frame preferably adopt Q960 shape steel plate to make), main beam 5 is W type beam, longeron 2 is variable section structure, leading portion sectional area is less than back segment, longeron 2 by upper and lower wing plate and respectively the web vertical with upper and lower wing plate form, the upper surface of web and the welding of upper flange lower surface align center, the front end of web aligns with upper flange; The lower surface of web and the welding of lower wing plate upper surface align center, the front end of web aligns with lower wing plate.Web equal intervals is provided with the through hole matching with main beam 5, and main beam 5 vertically runs through being welded on collar tie beam 1 that longeron 2 is parallel to each other.Trailer coupling 3 is welded between the leading portion of two longerons 2, is vertically welded with some secondary crossbeams 4 between the back segment of two longerons 2, and trailer coupling 3 is for the horizontal frame 6 of traction and draw the I-shaped structure that vertical frame 7 forms.The upper surface of trailer coupling 3 is concordant with the upper surface of longeron 2.Adopt after said structure, under equal load-carrying capacity, required steel weight can reduce approximately 20%.
