Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Embodiment
The utility model embodiment provides steel spring assembly before a kind of automobile major-minor formula, see Fig. 1, before described automobile major-minor formula, steel spring assembly comprises center bolt 4, the main spring 5 be connected with center bolt 4, the anti-attrition pad 10 be connected with main spring 5 both ends, with the auxiliary spring 7 be connected bottom main spring 5, the clip 6 be arranged on main spring 5 two ends, is arranged on the grasswort 8 of main spring 5 front end, is arranged on the hanger 9 of main spring 5 rear end.
Main spring 5 comprises the 3rd carrier spring plate 3, second carrier spring plate 2 and the first carrier spring plate 1 superposing setting successively, 3rd carrier spring plate 3, second carrier spring plate 2 and the first carrier spring plate 1 are provided with pad between any two, and the 3rd carrier spring plate 3, second carrier spring plate 2 and the first carrier spring plate 1 two ends are provided with connecting bore.
Auxiliary spring 7 is made up of a plate spring, and its end is connected with downward support hanger 11, is connected to the below of the 3rd carrier spring plate 3 by center bolt 4.
Powder metallurgy lining is equipped with in grasswort 8 and hanger 9.
See Fig. 3, the second carrier spring plate, the 3rd carrier spring plate two ends punching press have long waist type noise reduction hole 12.
See Fig. 4, the 3rd carrier spring plate two ends punching press has conical rivet hole 13, to be suitable for press-fiting of two ends riveted joint clip.
Steel spring assembly before this automobile major-minor formula, comprise three carrier spring plates, pad and center bolts, main spring is fixedly connected with the combined action of pad; Center bolt runs through main spring in the straight center section of main spring; Main spring is made up of three plate springs, i.e. the 3rd carrier spring plate, the second carrier spring plate and the first carrier spring plate, auxiliary spring is made up of a plate spring, and a plate spring is equipped with in the below of the 3rd carrier spring plate, its one end connects a downward support hanger, and the other end is connected to the below of main spring by center bolt.Also pad is housed below auxiliary spring.Identical with the support pattern of most of automobile front plate spring, for one end adopts fixing grasswort, the other end and rear end adopt the hanger connection mode swung.
Before this automobile major-minor formula, steel spring assembly is made up of main spring and auxiliary spring; when automobile load is less time; main spring plays a major role; when automobile load is larger; main spring and auxiliary spring play a role simultaneously; vehicle vibration damping is effective, and can protect main spring, can improve again the Rigidity and strength of this steel spring.
Each carrier spring plate material is 22 × 90 flat flat 50CrVA, and through repeatedly roll forming, stress shot blasting process, forms after quenching heat treatment.Auxiliary spring steel plate materials is 15 × 90 flat flat 60Si2Mn, after repeatedly roll forming bending, form auxiliary spring lower support structure.Form with enamelling process finally by after quenching heat treatment.Auxiliary spring is very thick, and in order to keep good material quenching performance, lower bracket strictly should be pressed engineering factor technique and make.Last operation is that doing of steel plate spring assembly assembles front japanning, and press-fits assembling plate spring assembly, needs grease of graphiting during assembling between leaf spring.
