Abstract
Provided is an oval spring for an automobile air valve. The oval spring for the automobile valve is made of a steel wire in a winding mode, and is spiral. A cross section of the steel wire is an oval. The extending direction of a short shaft of the oval is the same as the axial direction of the oval spring, a ratio between a long shaft and the short shaft of the oval is 1.25:1, and a cross sectional area of the steel wire is 4square millimeters-9square millimeters. Compared with the prior art, due to the fact that the cross section of the steel wire is oval, compared with a spring with a round cross section of the same cross sectional area, the oval spring for the automobile valve can reduce solid height of an air valve spring, reduces the area of the spring, reduces size and weight of the automobile, and meanwhile is long in service life.
Description
Technical field
The utility model relates to a kind of deformed spring, is specifically related to a kind of automobile air valve elliptic spring.
Background technique
The cross section of the steel wire of existing valve spring of automobile engine is normally circular, yet, because the continuous renewal of car engine machine technology is regenerated, require valve spring in limited length range, can produce larger elastic acting force, and require spring itself to have long working life.Existing section of steel wire be circular valve spring, has larger volume, be difficult to satisfy existing engine weight gently, the requirement of miniaturization.
The model utility content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of automobile air valve elliptic spring, and its installation volume is little, and long service life can satisfy usage requirement.
For achieving the above object, the utility model adopts following technological scheme:
The automobile air valve elliptic spring, this spring is the helical that is formed by steel wire wound, the cross section of steel wire is an ellipse, the bearing of trend of the minor axis that this is oval is axial consistent with this spring, and the ratio of major axis that should ellipse and the length of minor axis is 1.25:1, and the cross sectional area of steel wire is 4 square millimeters-9 square millimeters.
The central diameter of this spring is 14.5mm-17.5mm.
The beneficial effects of the utility model are:
Than prior art, valve spring of the present utility model, the cross section ovalize of its steel wire, the steel wire that contrasts same sectional area is the spring of circular cross-section, it can reduce pressure and the height of valve spring, reduce the volume of spring, alleviate the volume and weight of motor car engine, have simultaneously the advantages such as long service life.
Description of drawings
Fig. 1 is the structural representation that the utility model automobile air valve is used elliptic spring;
Fig. 2 is the sectional view of Spring Steel Wire shown in Figure 1.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
As shown in Figure 1, 2, be a kind of automobile air valve elliptic spring of the utility model, this spring is the helical that is formed by steel wire wound, the cross section of steel wire is an ellipse, the bearing of trend of the minor axis that this is oval is axial consistent with this spring, and the ratio of major axis that should ellipse and the length of minor axis is 1.25:1, and the cross sectional area of steel wire is 4 square millimeters-9 square millimeters.
The central diameter of this spring is 14.5mm-17.5mm.
To one skilled in the art, can make other various corresponding changes and deformation according to technological scheme described above and design, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
