Abstract
The utility model discloses a dust helmet for a sphere joint assembly. The inner wall of the upper part of a helmet body (1) is provided with a plurality of cowls (1.1) which can be hooped on a sphere joint pin; a round metal framework (3) is embedded at the bottom of the helmet body (1); a plurality of elastic metal sheets (3.1) are distributed on the inner wall of the metal framework (3); and the helmet body (1) is undulatory. The utility model has the advantages of simple manufacture, easy and convenient installation and simple structure.
Description
Technical field:
The utility model relates to a kind of dust proof member, specifically is that a kind of fine sand, dust etc. of can preventing enter the dust-proof cover on the ball joint assembly of being used for of ball joint assembly inside.
Background technique:
Ball joint assembly is a critical component in the present all kinds vehicle component, yet the Environmental Conditions of ball joint assembly makes dust, silt etc. be easy to enter into assembly inside, destroy the contact surface of ball stud and ball seat, cause ball stud flexible swinging degree to descend, shorten the working life of ball joint assembly greatly, and the use of dust-proof cover influences the flexibility of ball stud swing and the working life of ball joint assembly in order effectively to stop dust, silt etc. to enter into assembly inside just.
As shown in Figure 1, at present, for dust-proof cover can be connected between ball seat and the ball stud, prior art is used for the dust-proof cover of ball joint assembly when its cover body 1 upper inside wall is provided with some lips of holding tightly on ball stud 1.1, also on the outer wall of its cover body 1 bottom, be provided with the annular groove 1.2 that can place collar, and the inwall of cover body 1 bottom ringwise the projection 1.3.Notice of authorization number is called for the CN100368693 name and discloses a kind of and the similar dust-proof cover of said structure in the patent of invention of spherojoint.Though the dust-proof cover of said structure is made and structure is all fairly simple, more complicated, trouble but the assembling of this dust-proof cover but seems, promptly before assembling, the workman at first will cut out on ball seat and be used for the circular groove that cooperates with annular protrusion 1.3 together, and when assembling, the workman need use special tooling that the infraoral of cover body is strutted the circular groove position that is placed on ball seat, and then utilize special tooling that collar is strutted in the annular recess 1.2 that is placed in the dust-proof cover bottom, thereby dust-proof cover is closely linked to each other with ball seat and reach the purpose of sealing.
The model utility content:
The technical problems to be solved in the utility model is, provide a kind of not only make simple, and simple installation, the dust-proof cover that is used on the ball joint assembly simple in structure.
Technical solution of the present utility model is, a kind of dust-proof cover on the ball joint assembly of being used for following structure is provided: its cover body upper inside wall is provided with some lips that are connected on the ball stud; Described cover body bottom is embedded with a circular metal skeleton; Be distributed with a plurality of elastic sheet metals on the described metal frame inwall.
After adopting above structure, the utlity model has following advantage: be about to make in the mold cavity of dust-proof cover because the utility model when making, only need be placed on metal frame, inject rubber or polyurethane then and just can make the dust-proof cover moulding, therefore, production method of the present utility model is comparatively simple; In addition, the utility model when mounted, neither need on ball seat, cut out one circular groove, do not need to use special tooling and collar yet, it only needs the utility model is placed on the pressure head of hydraulic press or air press, slowly dust-proof cover being pressed ball seat with suitable pressure then gets final product, after dust-proof cover is in place, be distributed in that elastic sheet metal on the metal frame inwall will be squeezed power and natural torsion upwarps, after unclamping pressure head, it is that elastic sheet metal will rebound naturally that this bending upwarps the position, thereby infraoral of the present utility model is close on the ball seat and reaches the purpose of sealing, compared with prior art, this mode is very simple and convenient; Also have, compared with prior art, the utility model neither needs to be provided with annular groove under the situation that only increases a metal frame, also do not need to be provided with annular protrusion, so its structure is still fairly simple.
As a kind of improvement of the present utility model, described cover body can be the corrugated cover body.Length when cover body is arranged to corrugated and can be increased cover body and stretch, thus the sphere of activities of ball stud enlarged, strengthen the flexibility of ball stud activity.
