Abstract

The utility model discloses an aluminum alloy light-weight self-unloading car, which comprises a chassis, a sub-frame and a carriage, wherein the main body of the carriage is made of the high-strength aluminum alloy material. A connection device for a soleplate of the carriage and the sub-frame is of an out-cross connection device, a longitudinal beam of the soleplate is arranged at the outer side of a longitudinal beam of the sub-frame, and a carriage limiting seat is fixed between the sub-frame longitudinal beam and the soleplate longitudinal beam. The carriage is made of the high-strength aluminum alloy which belongs to the non-heat-treatment alloy and has good welding performance and good corrosion resistance, so the weight of the carriage is reduced to be one third of the ordinary steel carriage with the same size. The connection device for the soleplate of the carriage and the sub-frame is of an out-cross connection device, so the core of the carriage is reduced by about 120 mm, the weight utilization rate of the vehicle is remarkably increased, and the running stability and the lifting stability of the hydraulic system are greatly improved; and the lateral movement of the carriage is restricted, and the lateral stability of the vehicle is improved.

Description

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.
