Abstract

The utility model belongs to the technical field of microlight -type semi -mounted, full trailor, especially, relate to microlight -type semi -mounted, full trailer frame with abnormal shape longeron. The abnormal shape longeron includes two parallel arrangement's the roof beam body, and the roof beam position leads in the frame and expands outside the heterotypic roof beam duan chengxiang frame between guiding plate and suspension or the molding of contracting in the frame dorsad. The utility model discloses simple structure has changed the linearity of longeron, and special -shaped structure through the longeron improves self intensity of longeron, makes rationally lightening and do not influence its bearing performance from the beijing south maxpower technology co. Ltd of longeron, not only reduces steel and uses, has still increased the payload of vehicle, has improved the anti ability of jolting.

Description

It is provided with microlight-type semi-mounted, the full trailor vehicle frame of special-shaped longeron
Technical field
The utility model belongs to microlight-type semi-mounted, full trailor technical field, more particularly to the microlight-type for being provided with special-shaped longeron Semi-mounted, full trailor vehicle frame.
Background technology
As country keeps under strict control the road safety policy execution of overload, the research and development and production of lightweight vehicle are increasingly becoming vehicle The major tasks of manufacturing.Lightweight vehicle is mainly structure optimization to vehicle part, realizes the mitigation of quality, but by In longitudinal beam be the main supporting member of complete extensions/semitrailer, and the deadweight of longitudinal beam and holding for volume and extension/semitrailer entirely Beijing South Maxpower Technology Co. Ltd's power is directly proportional, so the deadweight of longeron cannot be mitigated, by taking 40 tons of vehicle heavy duty as an example, longeron is indulged from weighing about 1.5 tons or so Beam quality is too low, can cause serious potential safety hazard.In prior art, the substantially all employing of longitudinal beam of semi-mounted/full trailor Simple and practical linear pattern design, is easy to processing.Therefore, how the Mechanical Builds of longeron are improved, improve longeron Weight capacity, be those skilled in the art reduce with weight capacity vehicle rail conduct oneself with dignity R&D direction.
Utility model content
The purpose of this utility model is to provide a kind of microlight-type semi-mounted for being provided with special-shaped longeron, full trailor vehicle frame, this practicality New structure is simple, and the moulding to longeron is improved, and improves structural strength and anti-ability of jolting, and improves the load-bearing energy of longeron Power.
To solve above-mentioned technical problem, the technical solution adopted in the utility model is as follows:
Microlight-type semi-mounted, the full trailor vehicle frame of special-shaped longeron are provided with, the special-shaped longeron includes two beams be arrangeding in parallel Body, beam body is located between vehicle frame towing plate and suspension special-shaped beam section in extending out to vehicle frame or dorsad vehicle frame inside contracts moulding.
Preferably, the special-shaped beam section includes at vehicle frame towing plate front abnormal shape section and rear different at suspension Type section.Specifically, can be on the basis of the vehicle frame towing pin of semi-mounted/full trailor, backward about one meter is front special-shaped section, afterwards special-shaped section away from From longeron suspension about 3-30cm.
Preferably, the front abnormal shape section is identical with rear special-shaped segment structure, including the bending at horizontal segment and horizontal segment two ends Section, bending segment length is 3-30cm;Two bending sections composition V-shaped structure of forward and backward special-shaped section joint.
Preferably, connected by crossbeam between the flex point of the V-shaped structure of two beam bodies.
The outside tension force in longeron bottom when the crossbeam can be used to alleviate vehicle weight.
Preferably, the reinforcing plate that several spacing are 0.5-1m is provided between two beam bodies.
To prevent special-shaped longeron torsional deformation during vehicle heavy duty, in two longeron alien invasions (or interior facade)Install reinforcement additional Plate, the anti-yield force of riser in increase, the payload for making vehicle gets a promotion.
Preferably, the vehicle frame also includes the side bar frame of the frame-type being made up of two side girders and forward and backward side bar, special-shaped vertical Two, beam is one group and is set in parallel in side bar frame middle part with side girders.
The beam body thickness linear pattern longeron more of the prior art of special-shaped longeron described in the utility model is reduced, so reducing The consumption material and quality of longeron, but the defect of the remitted its fury caused to overcome beam body lower thickness, by longeron Special-shaped section(I.e. loading when longeron load-bearing section)Bending structure is designed to, rationally dispersion load-bearing pressure, improves special-shaped section beam body Load-bearing property, and then realize on the basis of the bearing capacity that beam body reaches design, reduce deadweight technical purpose.
The utility model compared with prior art, has the advantage that:Simple structure, changes the linearity of longeron, leads to The self-strength of the abnormally-structured raising longeron of longeron is crossed, the gravity energy of longeron is reasonably mitigated and is not affected its bearing Can, not only reduce steel and use, the payload of vehicle is also add, improve anti-ability of jolting.
Description of the drawings
Fig. 1 is the positive structure diagram of vehicle frame described in specific embodiment;
Fig. 2 is the overlooking the structure diagram of vehicle frame shown in Fig. 1.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only to explain The utility model, is not used to limit the utility model.
As shown in Figure 1-2, microlight-type semi-mounted, the full trailor vehicle frame of special-shaped longeron are provided with, the vehicle frame is also included by two Side girders 4 and front side beam 2, the side bar frame 1 of the frame-type of the composition of rear side bar 3, special-shaped longeron two is for one group and parallel with side girders The middle part of side bar frame 1 is arranged on, special-shaped longeron includes two beam bodies 8 be arrangeding in parallel, and beam body 8 is located at vehicle frame towing plate 5 and hangs Abnormal shape section 9 before special-shaped beam section is included at vehicle frame towing plate between system 7(Apart from the about 1m of towing pin 6)At close suspension Rear special-shaped section 10(Apart from suspension about 3-30cm), front special-shaped section 9 is identical with the rear structure of special-shaped section 10, including horizontal segment 11 And the bending section 12 at horizontal segment two ends, the length of bending section 12 is 3-30cm;Two bending section groups of forward and backward special-shaped section joint Into V-shaped structure 13, connected by crossbeam 14 between the flex point of the V-shaped structure 13 of two beam bodies, be provided between two beam bodies Several spacing are the reinforcing plate 15 of 0.5-1m.
The beam body thickness linear pattern longeron more of the prior art of special-shaped longeron described in the present embodiment is reduced, so reducing The consumption material of longeron and quality, but the defect of the remitted its fury caused to overcome beam body lower thickness, by the different of longeron Type section(I.e. loading when longeron load-bearing section)Bending structure is designed to, rationally dispersion load-bearing pressure, improves special-shaped section beam body Load-bearing property, and then realize reducing the technical purpose of deadweight on the basis of the bearing capacity that beam body reaches design.
The outside tension force in longeron bottom when crossbeam can be used to alleviate vehicle weight, while special-shaped during vehicle heavy duty to prevent Longeron torsional deformation, in two longeron alien invasions reinforcing plate is installed additional, the anti-yield force of riser in increase.
