Further improve:
The position that is positioned at the compartment installation portion on the described every longeron is connected with respectively two hangers that are used for connecting the spring plate that hangs back axle.
Further improve:
Cross-connecting apparatus comprises front cross rail, center member and the after cross member of channel steel type structure, and rivet with two longerons respectively at the two ends of described front cross rail, center member, and rivet respectively at the two ends of after cross member and the two ends of rear tailstock.
The another kind of improvement:
The outside lower forequarter of the compartment installation portion of two longerons is hinged with respectively the chain stay frame.
Further improve:
The rear end of chain stay frame is provided with rear damping, and fixedly journal stirrup, midway location are provided with the wheel hub fixed orifice.
The utility model adopts such scheme, has the following advantages:
1, on the structure of chassis side rail and crossbeam, with according to car load and the plate stamping of custom-designed variable section forms the channel steel type structure and substituted section bar square tube and rectangular tube; Normalisation and universalization degree are high, and production efficiency is high, make the high conformity of vehicle frame and car load, are more conducive to large-scale production in enormous quantities;
2, on product manufacture, blanked part substitutes section bar, and science has guaranteed the strong rigidity of vehicle frame accurately, and material has been saved in maximization, thereby reduces cost;
3, substantially substitute welding to rivet between longeron and the crossbeam, safety, reliable, decrease quality accident, reduce negative effect and past-sale service expense to brand.
The utility model is described in further detail below in conjunction with drawings and Examples.
