Aluminum alloy lightweight dumping truck
Technical field
The utility model belongs to heavy dump truck, is specifically related to a kind of aluminum alloy lightweight dumping truck.
Background technology
The compartment of tradition dumping truck all adopts steel plate class material, and thickness of slab will reach the strength and stiffness that respective standard could guarantee the compartment, but this has increased the quality in compartment simultaneously, is subjected to great restriction in many-sides such as conveying efficiency and fuel oil consumptions.Alleviate curb mass and just mean and to improve loading mass, promptly increased charge material amount factor of utilization.Generally speaking, car mass whenever alleviates 10%, and fuel oil consumption can reduce 6%-8%, and this is extremely helpful for raising conveying efficiency, reduction traffic cost, also helps reducing simultaneously fuel cost, energy savings.
The height of gravitational center of big volume dumping car directly influences the riding stability and the unloading stability of dumping car, and the fit system in known subframe and compartment is difficult to accomplish to lower the center of gravity on the basis of guaranteed performance.
The utility model content
In order to overcome the above-mentioned defective that the known technology field exists, the purpose of this utility model is, a kind of aluminum alloy lightweight dumping truck is provided, and adopts the novel high-strength light material, packing quality in the reduction; Provide a kind of new cabin floor structure and subframe to be used, reduce the compartment center of gravity, simple in structure, reasonable in design.
The aluminum alloy lightweight dumping truck that the utility model provides, comprise chassis, subframe, compartment, the header board in described compartment, cat ladder, hanger, side plate, base plate, back plate, subframe and wing plate all adopt the high-strength aluminum alloy material manufacturing, all the other important load parts still adopt the steel plate manufacturing, make bolt together with the steel junction.The base plate in described compartment and the connecting device of subframe are outer straddle type connecting device, the underframe longitudinal member, base plate limit crossbeam, base plate center member, subframe longeron, base plate bearing beam, the compartment limit base that comprise the compartment, described underframe longitudinal member is across the outside of subframe longeron, underframe longitudinal member, base plate limit crossbeam, base plate center member are connected to one, and form framed structure; The compartment limit base is fixedly installed between subframe longeron and the underframe longitudinal member; The cross-sectional plane of base plate bearing beam is the L type, and vertically pad and joins with the inboard of underframe longitudinal member on the base plate center member, and its inner plane and subframe longeron are accepted, and bearing all base plate center members before in compartment fuse by the base plate bearing beam.
The aluminum alloy lightweight dumping car that the utility model provides, the compartment material therefor is a high strength aluminum alloy, belongs to non-heat treated alloy, has good welding performance and good resistance to corrosion, carriage weight is reduced to 1/3rd of unidimensional common iron compartment.The base plate in compartment and the connecting device of subframe are outer straddle type connecting device, and the compartment center of gravity reduces about 120 millimeter, and the quality utilization rate of vehicle obviously increases, and has improved conveying efficiency, has reduced traffic cost; Roadability and hydraulic efficiency pressure system lifting stability increase substantially; Limit the side travel in compartment, improved the lateral stability of vehicle.

The specific embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, the aluminum alloy lightweight dumping truck that the utility model is provided is described in detail.
Embodiment
With reference to Fig. 1-Fig. 3, the aluminum alloy lightweight dumping truck of present embodiment, comprise chassis 1, subframe 2, compartment, the header board 3 in described compartment, cat ladder 4, hanger 5, side plate 6, base plate 7, back plate 9 and fender guard 13 all adopt the high-strength aluminum alloy material manufacturing, all the other important load parts such as hinge seat 8, hinge arms 10, open-and-close mechanism 11, back guardrail 12 etc. still adopt the steel manufacturing, make bolt together with the steel junction.The base plate 7 in described compartment is outer straddle type connecting device with the connecting device of subframe 2, the underframe longitudinal member 18, base plate limit crossbeam 14, base plate center member 15, subframe longeron 19, base plate bearing beam 21, the compartment limit base 20 that comprise the compartment, described underframe longitudinal member 18 is across the outside of subframe longeron 19, underframe longitudinal member 18, base plate limit crossbeam 14, base plate center member 15 are connected to one, and form framed structure; Compartment limit base 20 is fixedly installed between subframe longeron 19 and the underframe longitudinal member 18; The cross-sectional plane of base plate bearing beam 21 is the L type, and vertically pad and joins with the inboard of underframe longitudinal member 18 on base plate center member 15, and its inner plane and subframe longeron 19 are accepted, and compartment bearing 17 all base plate center members before fuse by base plate bearing beam 21.
The aluminum alloy lightweight dumping truck of present embodiment, the high-strength aluminum alloy material of employing belongs to non-heat treated alloy, has good welding performance and good resistance to corrosion; Section bar and sheet material are handled at machine up front surface initial oxidation, the oxidation film layer densification, and wear-resisting, postwelding does not need the processing of spraying paint, and has saved operation in attractive and durable yet, has shortened the vehicle production cycle, has improved production efficiency.
