Description
Technical field
The utility model relates to aluminum superimposed trailer manufacturing technology field, relates in particular to a kind of light-weighted semi-trailer longeron.
Background technology
Vehicle frame is made up of two longeron and some crossbeams, side bar and diagonal braces etc. that are positioned at the right and left, and longeron is commonly called as crossbeam, and is consistent with the motor vehicle length direction, and crossbeam connects into crash-resistant rigid frame with riveted joint, bolted connection or welding process and two side girders.Whether the connection of longitudinal and cross beam firmly is related to complete vehicle structure stability, compressive strength and service life.
Existing longeron is many to be formed with steel plate welding or shaped steel, and section is generally I-shape.The double-tee longeron comprises upper flange and the lower wing plate that is in upper and lower sides respectively, and two ends respectively with upper and lower wing plate bonded assembly web; Crossbeam passes web or disconnection and web welding.
In use for some time, or after standing violent bump, vehicle frame is prone to by load impacting distortion or fracture, and especially in crossbeam and longeron junction, fracture probability is higher.
The utility model content
The utility model embodiment provides a kind of light-weighted semi-trailer longeron, 1, can enlarge the area of contact between crossbeam and longeron, make be difficult between crossbeam and the longeron breaking away from, fracture, optimize the overall load-carrying properties of vehicle frame.2, T type groove makes things convenient for the installation of bracing device.
For realizing above-mentioned purpose, the utility model embodiment provides following technical scheme:
A kind of light-weighted semi-trailer longeron comprises the upper flange and the lower wing plate that are in upper and lower sides respectively, and two ends respectively with said upper flange and said lower wing plate bonded assembly web, on the said web several projections is set, said projection is vertical with said web.
Preferably, the length of said projection is the 1-80mm of crossbeam.
Preferably, the position of said projection is crossbeam and said web contact surface place.
Preferably, said projection is arranged on the one-sided or bilateral of said web.
Preferably, said web and said lower wing plate junction are provided with T slot, and said T slot is arranged on the one-sided or bilateral of said web.
Preferably, said lower wing plate edge is provided with reinforced rib.
Compared with prior art, the utlity model has following beneficial effect:
1, firm crossbeam: the projection on the web generally is on the outward flange that runs through crossbeam and said web contact surface, supports in the outside, stablizes crossbeam, with dispersive stress, prevents the flexural deformation of crossbeam;
2, one-shot forming: reinforced rib on the several projections on the web, T slot, the lower wing plate and the one-shot forming of longeron body, can realize through the aluminium section bar fashion of extrusion, improved the intensity and the stability of longeron; And when having avoided the crossbeam diagonal brace to install, need destruction such as perforate or welding girder work on web and lower wing plate;
3, module design: projection, T slot as the structure that longeron itself carries, are made the simplification that is connected of longeron and crossbeam, bracing device can directly be assembled into one.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use among the embodiment below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the structural representation of the utility model embodiment two;
Wherein, 1, upper flange, 2, lower wing plate, 3, web, 4, projection, 5, T slot, 6, reinforced rib.
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment strengthen the Joint strenght of longeron and crossbeam, bracing device, and this three and longeron is integrally formed through on the web of superimposed trailer longeron, setting up projection, T slot, reinforced rib, has improved longeron stability.It below is specific embodiment.
Embodiment one, referring to Fig. 1.
A kind of light-weighted semi-trailer longeron comprises the upper flange 1 and lower wing plate 2 that are in upper and lower sides respectively, and two ends respectively with said upper flange 1 and said lower wing plate 2 bonded assembly webs 3, on the said web 3 several projections 4 is set, said projection 4 is vertical with said web 3.
The position of projection 4 is in crossbeam and the said web 3 contact surface places.Projection 4 is on the outward flange of contact surface, and projection 4 may be stuck in the bottom of crossbeam, increases area of contact, reduces stress, and behind welding or riveted joint, the bolted connection, projection 4 can be placed crossbeam effectively and moved.
The length of projection 4 can be 1-80mm, looks actual demand and decides.Obviously, the long more more firmly crossbeam of projection 4, but long boss, the boss upper surface needs certain downward radian, to allow certain beam deformation, reduces stress concentration.
Longeron can adopt high-intensity 6XXX line aluminium alloy material: like 6082/6061/6005A/6063 etc.Projection 4 can be one-body molded through aluminium section bar fashion of extrusion and longeron.
Embodiment two, referring to Fig. 2
On the basis of embodiment one, web 3 is provided with T slot 5 with said lower wing plate 2 junctions.T slot 5 is the big groove of young internal diameter, can the chimeric objects wherein such as bolt of diagonal brace be stuck in T slot 5 inside securely, makes its difficult drop-off.T slot 5 on the web 3 can be integrated itself and longeron the chuckings such as bracing device of longeron side, and steadiness is stronger, and makes longeron module design, simplification, has avoided simultaneously destroying girder work at secondaries such as 3 perforates of longeron lower wing plate or welding.
Preferably, the angle of the rotational symmetry line of T slot 5 and lower wing plate 2 inside faces is 30-75 °, is preferably about 40 °.Make T slot 5 both within reason near web 3, divide to press close to lower wing plate 2 only, concrete angle and width are selected according to the actual requirements.
In addition, on the basis of embodiment one or embodiment two, lower wing plate 2 edges are provided with reinforced rib 6.Reinforced rib 6 can be one-body molded through the aluminium section bar fashion of extrusion with longeron, strengthens steadiness.Lower wing plate 3 bears huge tensile stress under load-up condition, and because to be connected area little with web, self is with totally the vehicle frame torsional property is poor.Utilize the advantage of aluminium extrusion, the stress of lower wing plate can significantly be optimized, reduced to the lower wing plate reinforced rib of an extrusion forming, increases the torsional property of longeron simultaneously.
More than a kind of light-weighted semi-trailer longeron that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper the principle and the embodiment of the utility model are set forth, the explanation of above embodiment just is used to help to understand the method and the core concept thereof of the utility model; Simultaneously, for one of ordinary skill in the art, according to the thought of the utility model, the part that on the specific embodiment and field of application, all can change can know that to sum up this description should not be construed as the restriction to the utility model.
