Existing deflector hermetically-sealed construction pattern is various, it adopts TPE(Thermo Plastic Elastomer mostly, thermoplastic elastomer) encapsulate, polyamide skeleton, PP(polypropylene) textural association such as cover plate and foamed glue forms, and structure is more complicated and cost is higher.
The conflict that existing deflector hermetically-sealed construction exists cost and performance obviously, cost performance is lower, assembling difficulty and easily coming off, the shortcoming such as sound insulation value reduction after being dismounted for multiple times.
Utility model content
The technical problems to be solved in the utility model is the defect that overcomes prior art, and a kind of good seal performance is provided, and assembles simply, do not allow caducous automobile steering device sealing arrangement.
The technical scheme that the utility model adopts is:
A kind of sealing arrangement of automobile steering device, comprise: steering gear input shaft protective cover and steering gear input shaft seal closure, described steering gear input shaft protective cover is fixed in deflector, described steering gear input shaft seal closure is positioned at above described steering gear input shaft protective cover, and described steering gear input shaft seal closure is that elasticity interference fit is connected with described steering gear input shaft protective cover.
Further, described steering gear input shaft protective cover is by the steering gear input shaft axial location of bench mark and described deflector.
Further, described steering gear input shaft seal closure is that elastic deformation compression is connected with vehicle body sheet metal.
Further, described steering gear input shaft seal closure and vehicle body sheet metal are greater than 7mm for elastic deformation amount.
Further, described steering gear input shaft protective cover is lower circle, the design of upper elliptic.
Further, the opening profile of the profile of described steering gear input shaft seal closure and vehicle body sheet metal matches.
Further, vehicle vehicle body sheet metal via hole is oval, and described steering gear input shaft seal closure is oval.
Further, the material of described steering gear input shaft protective cover is PA66, and/or the material of described steering gear input shaft seal closure is EPDM.
The utility model provides a kind of novel automobile steering device sealing arrangement, by optimal design, makes the simple in structure of described sealing arrangement, and assembling easily.Experimental test by cae analysis and many wheels proves that the more satisfactory reduction driving engine of structure energy of this kind of sealing arrangement is delivered to the noise of operator's compartment.
Wherein, the profile of described protective cover adopts lower circle, the design of upper elliptic, and its Main Function is in described deflector, described steering gear input shaft seal closure being fixed, so require described steering gear input shaft protective cover will have certain physical strength.The opening profile of the profile of described steering gear input shaft seal closure and vehicle body sheet metal matches, and has guaranteed the sealing effectiveness of whole mechanism, so vehicle vehicle body sheet metal via hole is oval, so described steering gear input shaft seal closure also adopts elliptic design.On described steering gear input shaft seal closure and vehicle body fitting surface, have the sealing band design of three places, this structure can reduce noise transmission effectively, and the cavity design of body hollow type can weaken deflector vibration adverse effect to a greater extent.The material of described steering gear input shaft protective cover is PA66, and the material of described steering gear input shaft seal closure is EPDM(ethylene propylene diene rubber), with low cost, be easy to make, simple in structure, cost is low, good sealing effect, cost performance is high.
It is low that sealing arrangement of the present utility model not only has cost simple in structure, easy for installation, good sealing effect, and cost performance high, and make outstanding contributions reducing driving engine and be delivered on the noise of operator's compartment.
