Abstract
A lower limiting plate of an automobile shock absorber piston valve comprises a piston valve assembly. Through circulating holes are formed in the piston valve assembly, an upper limiting plate is arranged on the upper portions of the circulating holes, a lower limiting plate body is arranged on the lower portions of the circulating holes, and the end, close to the circulating holes, of the lower limiting plate body is provided with an arc end face with a protruding middle. The lower limiting plate of the automobile shock absorber piston valve has the advantages that bending deformation points can be limited by the arc of the lower limiting plate body when piston adjusting pieces are bent and deformed at various speeds through the arc design of the lower limiting plate body of a shock absorber piston, and thus the problem of stress concentration caused by one-point supporting in the valve piece deformation process can be solved. In the using process, the indicator diagram of a shock absorber is fuller and smoother, more work is done, and a better shock absorption effect is achieved.
Description
Technical field
The present invention relates to the lower limiting board of automobile shock absorber piston valve.
Background technique
Along with the fast development of automobile industry, people are more and more higher to the requirement of car comfort.Vibration damper is vibration isolation, reduction shake original paper important in automobile, has ensured travelling comfort and the operational stability of vehicle.And the internal performance of raising vibration damper, the working life of increase vibration damper.It is the new problem that our vibration damper industry faces.
Summary of the invention
The object of this invention is to provide a kind of automobile shock absorber piston valve lower limiting board, in use damper indicator diagram is fuller, round and smooth, more a lot of better effectiveness in vibration suppression that arrived of doing work.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of automobile shock absorber piston valve lower limiting board, it is characterized in that: comprise piston valve assembly, described piston valve assembly is provided with the opening of perforation, described opening top is provided with upper limit plate, described opening bottom is provided with lower limiting board, and described lower limiting board is provided with near one end of opening the curved end that protrude at middle part.
The radian of above-described curved end is π/5-π/3.
The invention has the beneficial effects as follows: the design of the arc of damper piston lower limiting board can make piston adjustment sheet in the time of bending deflection under each speed bending deflection point limited by the arc of lower limiting board, can reduce like this valve block distortion time, a bit support the concentrated problem of stress that causes.In use damper indicator diagram is fuller, round and smooth, more a lot of better effectiveness in vibration suppression that arrived of doing work.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
In figure: 1. upper limit plate; 2. opening; 3. piston valve assembly; 4. lower limiting board; 5. curved end.
Embodiment
From accompanying drawing 1, the present invention includes piston valve assembly 3, described piston valve assembly 3 is provided with the opening 2 of perforation, described opening 2 tops are provided with upper limit plate 1, described opening 2 bottoms are provided with lower limiting board 4, described lower limiting board 4 is provided with near one end of opening 2 curved end 5 that protrude at middle part, and the distortion of piston adjustment sheet is changed along with the radian of the curved end 5 of lower limiting board 4.Be π/5-π/3 o'clock at the radian of curved end 5, the distortion variation of piston adjustment sheet reaches desirable.
Lower limiting board 5 of the present invention adopts powdered metallurgical material to make, and better plasticity, can realize valve block and prolong cambered surface bending deflection, and in use damper indicator diagram is fuller, round and smooth, more a lot of better effectiveness in vibration suppression that arrived of doing work.
