Description
Technical field
The auxiliary spring up-set type becomes the rigidity variable-section steel sheet spring, belongs to the automobile leaf spring field, is specifically related to a kind of change rigidity variable-section steel sheet spring.
Background technique
Leaf spring is one of major part in automobile suspension system, it connects wheel and vehicle frame, bear the weight of compartment and load, and bear because of the uneven caused impact in ground and vibrations, because its structural limitations exists empty wagons to jolt or is fully loaded with fracture failure two class defectives.Particularly for the back axle leaf spring of bearing high load, if adopt the leaf spring of single rigidity in the situation that the enough rigidity of design strength is too high, when unloaded, vehicle jolts, and control stability is poor; Although if do not jolt during the lower empty wagons of design strength, the leaf spring strength deficiency, during heavy duty, easy-rupturing lost efficacy, and traditional leaf spring is constant along sheet length direction width and thickness, leaf spring weight is heavier, not only affects Gross Vehicle Weight, make vehicle oil consumption higher and also the waste steel.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of reasonable in design, can improve vehicle performance stability and not high, auxiliary spring up-set type energy saving of easy-rupturing, intensity become the rigidity variable-section steel sheet spring.
the technological scheme that its technical problem that solves the utility model adopts is: this auxiliary spring up-set type becomes the rigidity variable-section steel sheet spring, comprise the main reed that multi-disc is superimposed, main reed integral body is arcuation, two ends are upturned and the top, two ends is equipped with grasswort, it is characterized in that: upper end, described main reed central position is fixedly mounted with backing plate between a major-minor, between major-minor, the backing plate upper end is supported the auxiliary spring sheet that multi-disc is superimposed is installed, clamping bolt vertically passes multi-disc master reed, between major-minor, backing plate and multi-disc auxiliary spring sheet also connect as one above each one, main reed and auxiliary spring sheet two ends all are equipped with the clamp that prevents that the horizontal mistake of reed from going out.Multi-disc auxiliary spring sheet is just being put on multi-disc master reed, when unloaded, only main reed work is stressed, can guarantee that empty wagons does not jolt, when the bearing capacity increasing, the stressed increasing of main reed, main reed is deformed to certain position, the auxiliary spring sheet contacts with fulcrum on vehicle frame or compartment, it is stressed that the auxiliary spring sheet begins participation work, and this moment, rigidity of plate spring became the complex stiffness that main reed rigidity adds auxiliary spring sheet rigidity, and in the time of can guaranteeing heavy duty, leaf spring is continuous.
The length that is shorter in length than main reed of described auxiliary spring sheet.
Described main reed totally 4 be superimposed, 4 main reed width equate, the thickness of main reed is attenuation gradually from the central position to two ends.Each point stress on main reed cross section equates, alleviates reed weight, stiffness degradation, and it is large that elasticity becomes, and travelling comfort improves, and bearing strength does not reduce simultaneously.
Described auxiliary spring sheet totally 3 be superimposed, 3 auxiliary spring sheet width equate, the thickness of auxiliary spring sheet is attenuation gradually from the central position to two ends.Each point stress on auxiliary spring sheet cross section equates, alleviates reed weight, stiffness degradation, and it is large that elasticity becomes, and travelling comfort improves, and bearing strength does not reduce simultaneously.
Described clamp shape for main reed and auxiliary spring sheet is identical, and the clamp of main reed is greater than the clamp of auxiliary spring sheet, and clamp can prevent that main reed and the horizontal mistake of auxiliary spring sheet from going out.
Compared with prior art, the beneficial effect that has of the utility model is:
1, improve vehicle performance stability and easy-rupturing, intensity are not high: multi-disc auxiliary spring sheet is just being put on multi-disc master reed, when unloaded, only main reed work is stressed, can guarantee that empty wagons does not jolt, when bearing capacity increasing, the stressed increasing of main reed, main reed is deformed to certain position, the auxiliary spring sheet contacts with fulcrum on vehicle frame or compartment, and it is stressed that the auxiliary spring sheet begins participation work, and this moment, rigidity of plate spring became the complex stiffness that main reed rigidity adds auxiliary spring sheet rigidity, intensity is high, and in the time of can guaranteeing heavy duty, leaf spring is continuous;
2, the each point stress on multi-disc master reed and auxiliary spring sheet cross section equates, alleviates reed weight, stiffness degradation, and it is large that elasticity becomes, and travelling comfort improves, and bearing strength does not reduce simultaneously;
3, compare leaf spring weight saving 30% left and right of wide uniform thickness, namely saving steel 30%, and complete vehicle weight alleviates, fuel consumption reduction.
Description of drawings
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structure plan view.
Wherein: 1, backing plate 5, clamp 6, auxiliary spring sheet between main reed 2, clamping bolt 3, grasswort 4, major-minor.
Embodiment
Fig. 1 ~ 2nd, most preferred embodiment of the present utility model is described further below in conjunction with 1 ~ 2 pair of the utility model of accompanying drawing.
With reference to accompanying drawing 1 ~ 2: this auxiliary spring up-set type becomes rigidity variable-section steel sheet spring, comprise the main reed 1 that multi-disc is superimposed, main reed 1 integral body is arcuation, two ends are upturned and the top, two ends is equipped with grasswort 3, totally two of clamps 5, symmetry is arranged on main reed 1 two ends, goes out to prevent the horizontal mistake of main reed 1.Main reed 1 upper end, central position is fixedly mounted with backing plate 4 between a major-minor, between major-minor, the auxiliary spring sheet 6 that multi-discs are superimposed support to be installed in backing plate 4 upper ends, and totally two of clamps 5, symmetry are arranged on auxiliary spring sheet 6 two ends, to prevent that the horizontal mistake of auxiliary spring sheet 6 from going out, the length that is shorter in length than main reed 1 of auxiliary spring sheet 6.Clamping bolt 2 vertically passes between multi-disc master reed 1, major-minor backing plate 4 and multi-disc auxiliary spring sheet 6 and above each one is connected as one.
