Abstract
The utility model provides a light -duty semitrailer girder of strenghthened type, including the web, go up the pterygoid lamina, lower pterygoid lamina, the web face on open and to have the hole flanging, claw formula limit is designed into on the hole limit. The hole flanging can design to triangle -shaped, circular or oval, and the hole flanging is upper and lower or controls staggered arrangement, the utility model has the advantages of can show and alleviate the tare, reduction manufacturing cost, increase delivery economic benefits.
Description
Technical field
The utility model relates to automobile-used crossbeam, is specially a kind of reinforced light-duty semitrailer crossbeam.
Background technology
At present, traditional large girder construction is in order to strengthen the bearing capacity of crossbeam, and majority is made I shape or semi-shaped structure, and this crossbeam heaviness, abundant has increased the weight of vehicle itself virtually; Some producer is the weight that alleviates this crossbeam, and the web of grider is carried out to circular hole punching press, but circular edges is not done to any processing, although therefore alleviated crossbeam weight, but cannot ensure the bearing strength of crossbeam, the service life of having reduced crossbeam, and then also cause serious potential safety hazard.
Summary of the invention
For above-mentioned technical disadvantages, the utility model provides a kind of reinforced light-duty semitrailer crossbeam, in alleviating crossbeam weight, takes into account the bearing strength that improves crossbeam.
The technical solution of the utility model is: a kind of reinforced light-duty semitrailer crossbeam is provided, comprises web, upper flange, lower wing plate; On described web surface, have hole flanging, flange is designed to pawl formula limit.
Adopt this technical scheme, on web surface, have hole flanging and can significantly reduce the weight of crossbeam entirety, structural design is done in hole flanging limit simultaneously, be designed to pawl formula limit or erect limit, discharge stress, improve the bearing strength of crossbeam.
The further optimization of this programme, described hole flanging is triangle, circle or oval, and selected geometry depends on the width of web, and quantity makes a decision according to the length of web.
The further optimization of this programme, described hole flanging for up and down or left and right be staggered, geometric central point can be on web center line, the both sides up and down that are positioned at web center line that also can be symmetrical.
Advantage of the present utility model:
1, on web surface, have hole flanging and can significantly alleviate tare, reduce manufacturing cost, increase delivery economic benefit.
2, the bearing strength that strengthens crossbeam, extends its service life.
3, reduce vehicle body air resistance coefficient, and then reduce automobile-used oil consumption.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, 2, the utility model provides a kind of reinforced light-duty semitrailer crossbeam, comprises web (2), upper flange (3), lower wing plate (4); On described web (2) face, have hole flanging (5), flange (6) is designed to pawl formula limit. Hole flanging (5) design can suitably alleviate the weight of crossbeam, and then alleviates the weight of whole vehicle body, and the steel that stamp out can also further be recycled, and have reduced manufacturing cost; The design on limit, hole is in order to discharge stress, does not reduce the bearing strength of crossbeam (1).
Described hole flanging (5) can be designed to triangle, circle or oval, and selected geometry depends on the width of web (2), and quantity makes a decision according to the length of web (2).
The position of described hole flanging (5) can for up and down or left and right be staggered, the geometric central point of hole flanging (5) can be on web (2) center line, the both sides up and down that are positioned at web (2) center line that also can be symmetrical.
Design concept of the present utility model can be applied accordingly on automobile-used crossbeam or longeron.
The foregoing is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make distortion and improve, all should belong to protection domain of the present utility model.
Claims (3)
1. a reinforced light-duty semitrailer crossbeam, comprises web (2), upper flange (3), lower wing plate (4); It is characterized in that: on described web (2) face, have hole flanging (5), flange (6) is designed to pawl formula limit.
2. reinforced light-duty semitrailer crossbeam according to claim 1, is characterized in that: described hole flanging (5) is triangle, circle or oval.
3. reinforced light-duty semitrailer crossbeam according to claim 2, is characterized in that: described hole flanging (5) for up and down or left and right be staggered.
