Abstract
The utility model relates to a connecting base of a frame assembly of a truck with a circular tube-shaped crossbeam. The connecting base comprises an electrophoretic overflow launder, reinforcing ribs and circular holes used for connection, and is formed by punching alloy steel or casting cast steel, wherein at least one electrophoretic overflow launder is provided. By adopting the mode of connecting the base provided with the electrophoretic overflow launder with the circular tube-shaped crossbeam, electrophoretic ink in a tube beam or a tube cavity, and the like can be guaranteed to flow out in time so that the coating manufacturability of the frame assembly can be increased and the rigidity of the entire truck can be enhanced, thereby creating necessary conditions for realizing the self weight reduction of the entire truck as well as the great reduction of manufacturing cost. The connecting base has good application prospects in the aspects of increasing the coating manufacturability of the frame assembly, reducing the self weight and the production cost of the entire truck, increasing the rigidity and the accuracy of manufacturing of the frame assembly, and the like.
Description
Technical field
The utility model relates to field of mechanical technique, particularly relates to a kind of improvement of truck frame assembly.
Background technology
Domestic and international medium and heavy commercial vehicle/comm..vehicle frame assembly present stage is adopted " side bar formula " substantially, and promptly two longerons and the some crossbeams by the left and right sides constitutes, and adopts riveted joint or bolted connection by connecting panel between the two.Crossbeam and connecting panel generally adopt alloy-steel plate to strike out flute profile, and the crossbeam aerofoil is connected with the connecting panel aerofoil, and the connecting panel outside of belly is connected with the longeron outside of belly.The shortcoming of this structure is crossbeam, connecting panel parts manufacturing cost height; Scantling of structure is big, material is thick, causes the car load deadweight bigger; Vehicle frame riveting process process labour intensity is big.
Along with the development that lightweight of truck car load and high quality and low cost require, it is had higher requirement to each side such as chassis side rail structure, beam structure and materials.By adopting pipe shape crossbeam and being connected the base welded structure, the rigidity of frame assembly is promoted, thereby can reduce capacity weight and dynamic property and fuel economy that the car load deadweight improves truck.
Adopt pipe shape crossbeam and be connected the welded frame assembly of base, because pipe crossbeam particularity, when frame assembly carries out whole electrophoresis, easily enter electrophoresis liquid in the electrophoresis process pipe crossbeam, influence electrophoresis baking operation process, influence the final lacquer painting quality of vehicle frame, and electrophoresis is easily located residual electrophoretic fluid at tube cavity etc. after finishing.
In the world, tubular cross bearer be connected the base welded structure and certain application arranged at medium and heavy truck, it connects not carry potential overflow groove of understructure, but external frame assembly generally adopts each parts elder generation electrophoresis, carry out frame assembly stack-mounted technology mode afterwards again, there is following defective in this technology mode: parts transhipment and production process need effectively protect each parts lacquer painting, increase cost; Frame assembly must adopt the bolted connection of surperficial anti-rust treatment simultaneously, and its productive costs connects far above rivet; And production efficiency is low, is not suitable for operation in enormous quantities.
So need the structure of improvement connection base, to realize the parts eletrophoretic mode of assembling back frame assembly integral body earlier.
The utility model content
At the problems referred to above, the connection base of a kind of circular pipe type crossbeam truck frame assembly that the utility model proposes comprises electrophoresis overflow groove, reinforced rib, connection circular hole, is alloy steel punch forming or cast steel casting, one of electrophoresis overflow groove minimum number.
Described electrophoresis overflow groove is shaped as circular arc or triangle or rectangle or irregularly shaped.
Described electrophoresis overflow groove is connecting arrangement and position on base and the longeron bonded assembly plane, with respect to connecting 4 of base line of centers symmetric arrangement; Or, arrange 3 for triangle distributes; Or, arrange 2 with respect to connecting base line of centers skew distribution.
Described alloy steel punch forming, i.e. electrophoresis overflow groove, reinforced rib, connection circular hole punch forming;
Described cast steel casting, promptly the reinforced rib casting is cast the part, back and is carried out machinework, processes the electrophoresis overflow groove, connects and use circular hole.
Technique effect of the present utility model:
The connection understructure of similar external not charged swimming overflow groove structure is suitable for the technology mode of assembling frame assembly behind the parts elder generation electrophoresis, and this technology mode production efficiency is low, cost is high.
The utility model has electrophoresis overflow groove structure by employing and connects base, is suitable for the vehicle frame riveted joint and carries out electrophoresis for behind the assembly, and the lacquer painting that can obviously reduce in the parts logistics transport process protects cost, and the production efficiency height, is fit to produce in enormous quantities operation.Connect understructure and can guarantee in the frame assembly electrophoresis process pipe crossbeam tube chamber etc. that place's electrophoresis liquid in time flows out, need not open stream lacquer hole in addition at the longeron outside of belly, also need on the pipe crossbeam, not open stream lacquer hole in addition, the timely outflow of electrophoresis liquid, boiling and jet phenomenon have prevented to boil in the drying course, guaranteed that frame assembly lacquer painting quality is unaffected, guaranteed the structural strength of crossbeam.
The utility model is guaranteeing that factory has now under vehicle frame rivet line, the vehicle frame paint line main technique flow process unmodified situation, produces with original grooved beam structure frame assembly mixed flow.
The enforcement of this kind structure can effectively reduce manufacturing cost, improves the frame assembly coating process, improves frame assembly rigidity and accuracy of manufacture, reduces the car load deadweight, improves capacity weight and the dynamic property and the fuel economy of truck, has good application prospects.
