Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and working principle, the manufacturing process of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present invention, technological scheme had more complete, accurate and deep understanding to help those skilled in the art.
As Fig. 4, Fig. 5 and the expressed structure of the present invention of Fig. 6, the present invention is a kind of ball socket structure of automotive tie-rod end, comprise and be provided with ball pin 1, dust-proof cover 2, spherical shell 3, ball seat 5 and the capping 7 that connects bulb, described connection bulb places in the spherical shell 3, and the bar portion of described ball pin 1 stretches out from spherical shell 3.
In order to solve the problem that exists at the described present known technology of this specification background technique part and to overcome its defective, realization improves the goal of the invention of the andfrictional conditions of bulb and ball seat, and the technological scheme that the present invention takes is:
As shown in Figure 6, the ball socket structure of this automotive tie-rod end provided by the present invention, ball seat 5 of the present invention is a loop configuration, be located between the bulb of the inboard of capping 7, spherical shell 3 and ball pin 1, its end face contacts with the inner side surface of described capping 7, the material of described ball seat 5 is plastics, for example high strength such as acetal plastic, teflon, wear-resisting engineering plastics.
Inboard in spherical shell 3 and capping 7 has added ball seat 5, and described ball seat 5 adopts acetal plastics to constitute, and has avoided attenuating interior metal and metal friction and produces the heat that rubs, influences its total quality; The lubricant oil of need not annotating makes designs simplification, and it is convenient to bring for the Consumer in use.This ball seat impact strength changes very little between-40 ° and 110 °.The dimensional stability height, friction factor is little, and endurance significantly improves its performance.
From view of production technology,, on friction factor, obviously reduce because ball seat 5 has adopted polyoxymethylene to add the material of oiling agent.So quality is controlled easily during heat treatment, the unbalanced stress of the sphere of having avoided spherical shell hole R face and ball pin 1 when high frequency heat is handled, there are fusing point, roughness to increase and problem such as wear no resistance.
Be concrete exemplifying embodiment of the present invention below, supply those skilled in the art's reference when enforcement is of the present invention:
The structure embodiment of capping 7:
The sealing configuration of whole plate is adopted in capping 7 of the present invention.
Because the material of described ball seat 5 adopts acetal plastic, has avoided interior metal and metal friction, so, oil nozzle need be set as auxiliary oil-filling device in capping 7, make designs simplification, and sealing effect is better, uses convenient.
Connection bulb of the present invention is that diameter is less than the described ball pin neck that is connected bulb with the bar portion joint of described ball pin 1, the bar portion of described ball pin 1 stretches out from spherical shell 3 at described ball pin neck place, and the opening that described spherical shell 3 is positioned at described ball pin neck place is the conical bore of collar extension greater than internal orifice.
Adopt the design concept of full-shape at its pivot angle place, spherical shell 3 is designed to the full-shape structure, thereby the damage of having avoided the friction of spherical shell pivot angle place to be caused influences its flexibility that turns to and whole performance, and the corner angle is bigger, plays the effect of buffering when the vehicle racing.Rational in infrastructure, good manufacturability.
Dust-proof cover 2 be connected and fixed embodiment:
As shown in Figure 4 and Figure 5, the material of dust-proof cover 2 of the present invention is a flexible material, and an end of described dust-proof cover 2 is enclosed within on the spherical shell 3, and the other end is enclosed within on the body of rod of ball pin 1; Described dust-proof cover 2 is enclosed within on the cylindrical of spherical shell 3 one ends, establishes an annular groove, is provided with big collar 8 in this groove, and described dust-proof cover 2 chuckings are fixed on the spherical shell 3; Described dust-proof cover 2 is enclosed within on the cylindrical of the other end on the body of rod of ball pin 1, establishes the groove of an annular, is provided with lesser calorie circle 9 in this groove, and described dust-proof cover 2 chuckings are fixed on the body of rod of ball pin 1.
The dust-proof cover 2 lesser calorie circle by its upper/lower terminal 9 and big collar 8 again is fixing, sees through and enters the damage that product inside causes thereby reduce water and silt, has improved the sealability of product.
During assembling,, again it is packed in the spherical shell 3, load onto capping 7, use special-purpose riveting machine riveted good then, the dust-proof cover 2 that packages lesser calorie circle 9 is enclosed within on the spherical shell 3, put big collar 8 at last ball pin 1 ball seat 5 of packing into.
On the fitting surface of spherical shell 3 of the present invention and dust-proof cover 2, with described big collar 8 relevant positions, establish the groove of an annular, described big collar 8 is clamped on dust-proof cover 2 in this groove.
The setting of said structure makes dust-proof cover 2 tight and solid and reliable more with being connected of spherical shell 3.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technological scheme carry out; or design of the present invention and technological scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
