Abstract
The utility model provides a kind of steering rack dust-proof cover with arc surface, and described dust-proof cover comprises multiple crests and trough, and the fillet between described crest and trough is arc surface, and the radius of arc of described arc surface is R20-28.Said structure designs, and can strengthen tensile force and the decrement of dust-proof cover, reduces production cost, meanwhile, has extended the working life of product, is convenient to industrially application of product.
Description
Technical field
The utility model belongs to auto parts and components field, relates in particular to a kind of steering rack dust-proof cover with arc surface.
Background technique
The effect of automobile steering rack dust-proof cover is to prevent that dust, impurity etc. from entering the joint of front wheel shaft, also prevents that lubricant oil from therefrom overflowing simultaneously.As shown in Figure 1, it between the crest of automobile steering rack dust-proof cover of the prior art, is oblique straight flange, existing this oblique straight flange structure make the tensile force of dust-proof cover and the amount of tension property taken into account poor, and easily cause the joint between crest and trough to break, thereby affect the working life of dust-proof cover.
Given this, the utility model provides a kind of steering rack dust-proof cover with arc surface, the above-mentioned defect existing to solve dust-proof cover of the prior art.
Summary of the invention
The purpose of this utility model is to provide a kind of steering rack dust-proof cover with arc surface, the above-mentioned defect existing to solve dust-proof cover of the prior art.
In order to realize the purpose of this utility model, the utility model provides a kind of steering rack dust-proof cover with arc surface, described dust-proof cover comprises multiple crests and trough, and the fillet between described crest and trough is arc surface, and the radius of arc of described arc surface is R20-28.
The utility model, compared with prior art, provides a kind of steering rack dust-proof cover with arc surface, this kind of structural design, can strengthen tensile force and the decrement of dust-proof cover, reduces production cost, meanwhile, extend the working life of product, be convenient to industrially application of product.
Brief description of the drawings
Fig. 1 is the structural representation of automobile steering rack dust-proof cover in prior art;
Fig. 2 is structural representation of the present utility model;
In figure, 1-crest, 2-trough, the oblique straight flange of 3-, 4-arc surface.
Embodiment
In order to make the purpose of this utility model, technological scheme and beneficial effect clearer, below in conjunction with embodiment, the utility model is further elaborated.Should be understood to specific embodiment described herein only in order to explain the utility model, be not limited to protection domain of the present utility model.
As shown in Figure 1 and Figure 2, the utility model provides a kind of steering rack dust-proof cover with arc surface, and described dust-proof cover comprises multiple crests and trough, and the fillet between described crest and trough is arc surface, and the radius of arc of described arc surface is R20-28.
The utility model, compared with prior art, provides a kind of dust-proof cover with arc surface, and this kind of structural design can strengthen tensile force and the decrement of dust-proof cover, reduces production cost.
Through evidence, decrement of the present utility model and tensile force are splendid, for example, (ading up to example with 10 crests) is identical at maximum Wave crest and wave trough external diameter, under peak number amount same case, and the product that skew wall is circular arc can be that the product of facing directly can Duola be stretched 10mm than skew wall.And can multiple pressure contracting 3-5mm in the time of compression.(product that skew wall is circular arc in process of production effect in the wall thickness uniformity is better), the in the situation that of same outer diameter and expanded angle, it can be that the next crest Duola of situation who faces directly stretches 1-2mm and process evidence than transitional surface that crest changes arc surface into the excessive face of trough, when arc surface radian is between 20 ° to 30 ° time, can meet other parameter of product, and amount of tension and decrement the best.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
