The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
As one aspect of the present invention, provide and returned structure in a kind of vehicle.Like Fig. 5 and shown in Figure 6, return structure in this vehicle and comprise: casing 10; Poroid support portion 20, poroid support portion 20 comprises a plurality of mesh 21, and each mesh 21 is the polygons that surrounded by a plurality of stay bearing plates 22, and polygonal limit number is more than or equal to five; Connecting panel 30, poroid support portion 20 is connected with casing 10 through connecting panel 30.Preferably, polygon is an equilateral polygon, and polygon can not be an equilateral polygon also certainly.Preferably, the stay bearing plate 22 of the poroid support portion 20 of at least a portion is provided with opening 23, thereby reaches the purpose of expendable weight and material, has guaranteed that also poroid support portion 20 has enough mechanical properties simultaneously.Preferably, polygonal limit number is five or six.On technology, should adopt the mode of bending and molding as far as possible, when the angle between the stay bearing plate 22 of poroid support portion 20 is 120 °, have the advantages that to be easy to bending and molding, the destruction that can avoid weld defect to cause like this for important stressed member.
Like Fig. 5 and shown in Figure 6, the poroid support portion of returning in this vehicle in the structure 20 forms cellular structure, has broken through quadrangle reticulation of the prior art and radial structure.Owing to adopted cellular structure; Improved the uneven problem of stress distribution of returning the inside configuration stay bearing plate in the vehicle; Guaranteed to return in the vehicle structure and under 360 ° of revolution operating modes, all had intensity, rigidity and anti-deformation preferably, improved and returned structure bearing capacity in the vehicle.Simultaneously, also alleviated weight, reduced cost, optimized the ratio of the ratio that returns the intensity of structure and quality in the vehicle, rigidity and quality, alleviated the following heavy of vehicle, made vehicle satisfy the requirement of road running more easily.
As preferred embodiment a kind of, like Fig. 5 and shown in Figure 6, return structure in the vehicle and also comprise dividing plate 40 and supplemental support portion 50, dividing plate 40 is arranged on the inside of casing 10, and poroid support portion 20 and supplemental support portion 50 are separately positioned on the both sides of dividing plate 40.At this moment, return structure in the vehicle and have double-layer structure, promptly poroid support portion 20 and supplemental support portion 50, wherein, poroid support portion 20 is positioned at the upper strata, and supplemental support portion 50 is positioned at lower floor, is provided with dividing plate 40 between two-layer up and down.Like this, just can make upper strata (being poroid support portion 20) bear main working load, to guarantee under 360 ° of revolution operating modes, all having intensity, rigidity and anti-deformation preferably according to returning the distribution of stress characteristics of structure under working load in the vehicle; Simultaneously, also can select (for example selecting) multi-form understructure according to the loading characteristic of lower floor's (being supplemental support portion 50) of different vehicle (for example car hosit and crawler crane) according to effective bang path of power.Further, also can be designed to the form more than three layers or three layers, with further intensity, rigidity and the anti-deformation of improving with returning structure in the vehicle.
For example, a kind of preferred embodiment in, supplemental support portion 50 (being lower floor) can adopt radial supporting construction.As shown in Figure 7, supplemental support portion 50 comprises a plurality of stay bearing plates 51 that are radial setting.Preferably, supplemental support portion 50 comprises inner ring body 52, and stay bearing plate 51 is connected with casing 10 with inner ring body 52 respectively.The supplemental support portion 50 of this form is applicable in engineering trucks such as car hosit, using.
For example, in another preferred embodiment, supplemental support portion 50 (being lower floor) can also adopt the cancellate supporting construction of square.As shown in Figure 8, supplemental support portion 50 comprises a plurality of stay bearing plates 53, and a plurality of stay bearing plates 53 of supplemental support portion 50 are lined up a plurality of quadrangles.The supplemental support portion 50 of this form is applicable in engineering trucks such as crawler crane, using.
Preferably, can be provided with hole 41 by dividing plate 40, further to reach the purpose of expendable weight.In addition, guaranteeing that supplemental support portion 50 has under the prerequisite of enough mechanical properties, stay bearing plate that can also at least a portion supplemental support portion 50 is provided with one or more openings, thereby reaches the purpose of expendable weight and material.
Owing to adopted layering (for example two-layer or three layers) supporting construction; Therefore; Return structure in the vehicle and can bear multi-form working load respectively through different layers (for example the upper and lower); So that respectively the concrete structure of each layer is designed separately, be easy to make full use of the mechanical property of steel according to every layer load-carrying capacity.
FEM calculation shows; Under the condition of identical weight: return structure in the vehicle of (1) quadrangle grating texture and can't be implemented in to make under 360 ° of revolution operating modes and return structure in the vehicle and have stronger bending resistance torsion stiffness; Promptly only in several turning circles, have bending resistance torsion stiffness preferably, the bending resistance torsion stiffness is relatively poor in other turning circles.At this moment, return the restriction that structure bearing capacity receives local stiffness in the vehicle.Through FEM calculation, the resistance to deformation rigidity of cellular structure under 360 ° of revolution operating modes is compared with the quadrangle grating texture, has promoted 8%-15%.(2) return structure in the radial vehicle under 360 ° of revolution operating modes, stress mainly is distributed on the minority stay bearing plate, thereby it is serious uneven to cause integrated stress to distribute.Under 360 ° of revolution operating modes, the internal stress distribution of cellular structure is more even, structurally is beneficial to realization to the making full use of of steel mechanics performance, and avoids the uneven phenomenon of distribution of stress, this be radial and quadrangle grating texture can't realize.In addition, " in return " of cellular structure compared the bending resistance torsion stiffness and promotes 9%-13% with the radiation platy structure.
