Abstract
The utility model relates to a spiral adjustable structure, in particular to a stepped spiral adjustable structure for a shock absorber of an automobile. The stepped spiral adjustable structure for the shock absorber of the automobile comprises a spring seat, an adjusting spring seat, a spring and a spring plastic cushion. The spring seat is sleeved on an oil storage barrel, the spring plastic cushion is fixedly compressed with the top of the spring, and the spring seat is connected with the adjusting spring seat in a threaded manner and is matched with the adjusting spring seat. The stepped spiral adjustable structure has the advantages that five levels of pre-tightening force of the spring can be exerted by means of rotating the spring seat, and the stepped spiral adjustable structure is wide in application range and can be adjusted easily and conveniently.
Description
Technical field
The utility model relates to a kind of spiral adjustable structure, relates in particular to a kind of cascade spiral adjustable structure for automobile absorber.
Background technique
Along with expanding economy, the domestic logistics transport market is also thereupon flourish, has promoted medium and heavy Truck Market that earth-shaking variation occurs; Be main developing into take cab over engine as main from conventional cab; From medium-sized be that main to develop into heavy type be main; Along with the significantly lifting of truck active safety technology and passive security technology, from the simple satisfied requirement of driving, to the travelling comfort of more and more paying close attention to the driver, convenience; And the requirements such as the load-carrying of concern truck and Security.Now widely used cab vibration absorber can satisfy its requirement, but along with heavy goods vehicles development already, more and more higher to the requirement of vibration damper performance.
According to cylindrical spring compression and extension spring design calculation formula: F=K*f;
In formula: the amount of deformation under the work loads power (N) of F-spring, K-spring rate, the f-work loads;
Hence one can see that: the work loads power F of spring depends on the amount of deformation f under the spring work loads; Its spring rate K is constant, and f is larger when spring deflection, and then the work loads power F of spring is larger, i.e. spring hardening; Otherwise then F is less, i.e. weakening of spring.
Hence one can see that, and the work loads power F of spring directly depends on the amount of deformation f of spring in the constant situation of spring rate.
Because the structure of using on the present stage cab vibration absorber mainly relies on the spring of certain rigidity, fixing nut, its machining accuracy is relatively simple; Its spring deflection f is substantially constant, and the work loads power F of spring can not free adjusting, and therefore in the situation of different road conditions, its narrow application range can not satisfy the present stage automobile industry to the requirement of vibration damper.So how to make a kind of adjustable springs amount of deformation, make the using scope of vibration damper own become wide, just inventor's problem that will solve.
Summary of the invention
The utility model has solved the deficiencies in the prior art, and a kind of a kind of cascade spiral adjustable structure for automobile absorber that can the Regulation spring amount of deformation is provided.
Its concrete technological scheme is: a kind of cascade spiral adjustable structure for automobile absorber, comprise the spring seat, Regulation spring seat, spring, the spring plastic mattress that are set on the fuel tank, described spring plastic mattress, be fixed and clamped with the spring top, described spring seat is threaded and matches each other with described Regulation spring seat.
As preferably, described spring seat and described Regulation spring seat are respectively equipped with five sections adjustable ladder teeth.
The utility model can reach 5 grades of adjustable initial tension of spring by the rotating missile spring abutment, and Applicable scope is wider, and regulates simple and convenient.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment 1
Below in conjunction with Fig. 1 the utility model embodiment 1 is described in further detail:
A kind of cascade spiral adjustable structure for automobile absorber, comprise the spring seat 1, Regulation spring seat 2, spring 3, the spring plastic mattress 4 that are set on the fuel tank, described spring plastic mattress 4, be fixed and clamped with spring 3 tops, described spring seat 1 is threaded and matches each other with described Regulation spring seat 2.Described spring seat 1 is respectively equipped with five sections adjustable ladder teeth with described Regulation spring seat 2.Spring 3 is sleeved on the fuel tank, itself and spring seat 1 and Regulation spring seat 2 close-fittings, and spring plastic mattress 4 is fixed and clamped with the spring top, thereby forms cascade spiral adjustable structure.Spring 3 materials are TDSiMn, and shape is cylindrical, and its rigidity is constant, and length can freely be selected; Spring plastic mattress 4, material are PA6, are fixed and clamped with spring 3 tops, play the protection spring and avoid friction with the installation position.Spring seat 1 fabrication design becomes 5 sections adjustable ladder teeth are arranged, and material is 2A12, and its structure is the meshing adjusting point-to-point with Regulation spring seat 2.The same fabrication designs of Regulation spring seat 2 become 5 sections adjustable ladder teeth are arranged, and material is 2A12, and its structure is the meshing adjusting point-to-point with spring seat 1.During vibration damper work; travelling comfort and Security in order to satisfy the driver in different road conditions; the composite structure that can be rotated spring seat 1 and Regulation spring seat 2 is adjusted to suitable scope to the amount of deformation f of spring 3; because the rigidity of its spring 3 is constant; therefore the pretightening force F of spring 3 changes with the variation of f, and spring plastic mattress 4 has played protection spring 1 to avoid the friction with the installation position in this regulates in addition.By the application of cascade spiral adjustable structure on vibration damper, can reach 5 grades of adjustable initial tension of spring, thereby applicable different road conditions are wider.
Claims (2)
