Abstract
The utility model relates to a low-gravity-center dump truck frame special for engineering. A general heavy truck chassis is designed specially, and the advanced rivet-welding combination technology is adopted to realize a constant-strength frame structure with variable thickness and variable cross section, a left longitudinal beam and a right longitudinal beam are adopted to replace a common channel beam structure in a horizontal H-shaped beam manner to realize the constant-strength requirement; the traditional auxiliary frame is removed to improve the truck stability, so that the dump truck frame can be well adaptive to a severe road environment in an engineering site, the height of the gravity center of the whole truck is reduced, the dead weight of the whole truck is reduced, and the probability of turning over of the truck on the severe road surface is reduced. The dump truck frame is wide in front part and narrow in rear part, and mainly comprises the left longitudinal beam, the right longitudinal beam, a second cross beam, a middle cross beam, a balanced shaft beam, a rear cross beam and a subplate.
Description
Technical field
The utility model relates to engineering dump truck dedicated vehicle frame, specially refers to dumping car vehicle frame.
Background technology
Heavy-duty tipper is the visual plant of heavy construction Site Soil cubic meter of stone work, and engineering ground road surface uneven, and car driving process often one is taken turns and lifted or sink, and vehicle frame is often turned round state in the limit.Existing market main flow dumping car vehicle frame generally adopts universalization vehicle frame to reequip design, and do not carry out according to carry out customizations design with car environment, therefore vehicle frame generation early fracture breakoff phenomenon is very general, and due to the too high vehicle's center of gravity of existing of subframe, make vehicle under this bad working environments, very easily cause rollover.
Summary of the invention
In order to overcome, prior art Heavy Tipper Frame coefficient of mass utilization is low, center of gravity is high, the not high defect of customizations degree, the utility model proposes a kind of major-minor engineering of integrating dump truck dedicated vehicle frame.The utility model vehicle frame comprises: left longeron, right vertical beam, front cross rail, second cross beam, intermediate transverse girder, balance shaft beam, transom beam and subplate; Wherein, longeron is low early and high after variable section equal strength, adopts top airfoil, lower aerofoil and web to be welded to connect, and longeron assembly adopts bolt or rivet to be connected with crossbeam and subplate; Wide layout before and after body frame structure for automotive, width is 865mm.
Further, the utility model engineering dump truck dedicated vehicle frame is taked the wide layout in front and back, and front overhang length is 1430mm, and rear overhang length is 1855mm, and wheelbase is 3800mm.
Further, frame assembly is cancelled subframe, adopts major-minor Integral frame, and longeron adopts " work " word girder construction to realize the design of variable section equal strength, cancels lining girder construction, adopts individual layer deepened beam structure, realizes generally the effect that center of gravity falls in loss of weight.
Further, cancel subframe, the integrated floor side member depth of section of major-minor is 370mm, and longeron top airfoil thickness of slab is 14mm, and lower aerofoil is 16mm, and web thickness of slab is 14mm, and employing is welded to connect overall yield strength and is greater than 500MPa.
The utility model low center of gravity engineering dump truck dedicated vehicle frame adopts " work " word girder construction, has well solved the equicohesive designing requirement of variable section, with existing, mark vehicle vehicle frame is contrasted and has realized loss of weight 3.18%; Major-minor integrated design makes vehicle to the mark car weight heart, reduce by 18.89%.The utility model frame assembly has not only been realized the designing requirement of lightweight, low center of gravity, guaranteed that structural strength is improved mark vehicle simultaneously, realized engineering of the present utility model special-purpose, can adapt to engineering site complex road condition condition, stability and the service life of improving vehicle, actv. is kept away the rollover probability that has reduced car load.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic three dimensional views of the utility model dumping car vehicle frame embodiment.
Accompanying drawing 2 is schematic top plan view of the utility model dumping car vehicle frame embodiment.
Accompanying drawing 3 is the utility model dumping car frame carling structure schematic diagrams.
Below in conjunction with drawings and the specific embodiments, the utility model low center of gravity engineering dump truck dedicated vehicle frame is further illustrated.
The specific embodiment
Accompanying drawing 1 is the schematic three dimensional views of the utility model dumping car vehicle frame embodiment, and in figure, 1 is left longeron, and 2 is front cross rail, and 3 is right vertical beam, and 4 is second cross beam, and 5 is intermediate transverse girder, and 6 is balance shaft beam, and 7 is tail boom, and 8 is subplate; As seen from the figure, the utility model low center of gravity engineering dump truck dedicated vehicle frame, comprising: left longeron assembly 1, right vertical beam assembly 3, front cross rail 2, second cross beam 4, intermediate transverse girder 5, balance shaft beam 6, transom beam 7, subplate 8 form; Wherein longeron assembly is connected by bolt or rivet with each crossbeam and subplate.And the upper and lower aerofoil of longeron and longitudinal-beam web plate are to be welded to connect, before and after well having solved longitudinal-beam web plate, cross section is different, the mechanical property that " work " word beam is good and the sheet material of thickening provide enough intensity, realized that major-minor is integrated have been increased vertical depth of beam but compared with there being the vehicle frame of subframe, overall height declines, and falls heavy successful.
Accompanying drawing 2 is birds-eye vieies of the utility model low center of gravity engineering special vehicle vehicle frame, and as seen from the figure, the utility model dumping car vehicle frame is the wide layouts in front and back, and before and after vehicle frame, width is 865mm, and front overhang length is 1430mm, and rear overhang length is 1855mm, and wheelbase is 3800mm.
Accompanying drawing 3 is schematic cross-sections of the utility model low center of gravity engineering special vehicle chassis side rail, in figure, 1 is that top airfoil, 2 is that web, 3 is lower aerofoil, as seen from the figure, top airfoil 1 thickness of longeron is 14mm, web 2 thickness are 14mm, lower aerofoil 3 thickness are 16mm, and vehicle frame top airfoil and lower aerofoil width are all 96mm, and top airfoil and lower aerofoil welding trailing web ala lateralis face length degree are 16mm.
In order to realize lightweight and low center of gravity designing requirement, the utility model engineering dump truck dedicated vehicle frame has adopted low early and high after longitudinal-beam web plate to realize variable section equal strength, and it is integrated to have cancelled subframe employing major-minor.Longitudinal-beam web plate is that individual layer thickening plate is cancelled lining beam, than girder lining girder construction, subtracts thick 2mm, but overall structure intensity is improved, use WL590 material can reach more than 500Mb intensity.
Through the customizations design requiring for engineering ground, this utility model engineering dump truck dedicated possesses low center of gravity, weight-saving advantage, use the engineering dump truck dedicated of this kind of model vehicle frame to have better comformability to the severe road conditions in heavy construction place, whole vehicle stability is better, and reduced the danger of vehicle rollover, novel longeron assembly structure mechanical property is obviously better than existing structure, and be improved significantly its service life.
