Abstract

The utility model discloses a ball pin assembly of an automobile. The ball pin assembly comprises a ball seat, a ball sleeve, a ball and a dustproof sleeve. The ball seat is of an integral structure, and a limiting mechanism used for limiting the ball seat in axial movement is arranged on the ball seat. The ball seat is of the integral structure, so that a ball pin is guaranteed against being released from the lower side of the ball seat when under excessively high axial pressure, and the driving stability is guaranteed. The ball pin assembly has the advantages that the ball pin assembly is stable in structure and is safe and reliable, and the ball pin is flexible in running. The utility model is applicable to ball pin assemblies of various automobiles.

Description

Background technology

At present, automobile ball pin assembly commonly used mainly is comprised of ball seat, ball cover, ball pin main body, dust boot etc.Ball seat links to each other with swing arm by being press fit in the swing arm hole, and pin rod links to each other with steering swivel with locating dowel pin by nut.In the prior art, the rear end of ball seat is used for the ball seat sealing with rear pressing cover usually, and this kind structure is in vehicle traveling process, when ball pin is subject to axially excessive pressure, it may be deviate from from rear pressing cover, causes the ball pin main body to lose efficacy, thereby affects the safety performance of car load.

The utility model content

For solving the deficiencies in the prior art, the utility model provides a kind of automobile ball pin assembly, and ball seat is designed to integral structure, has guaranteed ball pin when being subject to axial excessive pressure, can not deviate from from the ball seat below, and then guarantee the stability of driving.

For achieving the above object, the technical scheme that adopts of the utility model is as follows:

A kind of automobile ball pin assembly comprises ball seat, ball cover, spheroid, dust protecting cap, and described ball seat is the integral type structure, and ball seat is provided be used to the stop gear that limits its axial motion.

As to improvement of the present utility model, described stop gear is the annular stop circle that extends radially outward of being located at the ball seat periphery.

As another kind of the present utility model is improved, described automobile ball pin assembly also comprises gland;

Described gland is sleeved on the ball neck place of ball pin main body, turns round 360 ゜ by L shaped cross section and is become structure, the radially clamping of buckling groove place between the outer end of described gland and ball seat on the ball seat inwall; The bottom end face of described gland contacts with the ball cover end face, and axial top end face contacts with the dust protecting cap bottom surface, and axial outside face contacts with the dust protecting cap inside face.

As further improvement of the utility model,

Anyhow the angle between two parts in the L shaped cross section of described gland is acute angle.

There is the gap between the axial vane surface of described gland inboard and the outer peripheral face of spheroid.

The utility model also has a kind of improvement, and the neck periphery of described ball pin main body is set be used to avoiding dust protecting cap to sink to the bracing ring of ball pin main body neck.

Further feature of the present utility model also has: described automobile ball pin assembly also comprises pin rod, is furnished with nut, locating dowel pin, fixes through nut and locating dowel pin when described pin rod and steering swivel assembling.

Owing to adopted technique scheme, the utility model compared with prior art, obtained technological advance is:

1. the utility model is designed to integral structure with ball seat, has guaranteed ball pin when being subject to axial excessive pressure, can not deviate from from the ball seat below, and can limit ball seat axial motion in the swing arm hole after increasing limit coil;

2. the setting of gland, played the effect to ball cover and dust protecting cap axial location, and gland is designed to " L " loop configuration, guaranteed that ball pin assembly has enough pendulum angles in ball cover, and can not cause pin rod and ball seat to interfere, and then guaranteed the stability of ball pin assembly moment;

3. the setting of bracing ring has guaranteed that dust protecting cap can not sink to ball pin main body neck position.

In sum, the utlity model has Stability Analysis of Structures, safe and reliable, characteristics that ball pin goes slick.

The applicable ball pin assembly of making various automobiles of the utility model.

Description of drawings

Below in conjunction with drawings and the specific embodiments the utility model is done further to describe in detail.

Fig. 1 is the utility model embodiment integral structure scheme drawing.

Among the figure: 1, ball seat; 2, ball cover, 3, spheroid; 4, gland; 5, jump ring; 6, dust protecting cap; 7, bracing ring; 8, nut; 9, locating dowel pin; 10, annular stop circle; 11, pin rod.

The specific embodiment

Embodiment

A kind of automobile ball pin assembly, structure comprise ball seat 1, ball cover 2, ball pin main body, gland 4, dust protecting cap 6 and bracing ring 7 as shown in Figure 1, and the ball pin main body comprises spheroid 2 and pin rod 11.Wherein:

Ball seat 1 is the integral type structure, and it realizes being connected with swing arm by being press fit in the swing arm hole.The periphery of ball seat 1 radially has outward extending annular stop circle 10, and described limit coil 10 is positioned in the swing arm hole, is used for restriction ball seat 1 at the axial motion in swing arm hole.

Ball cover 2 is installed on the inner chamber of ball seat 1, and spheroid 3 is positioned at ball cover 2 and can rotates within it.

Gland 4 is sleeved on the ball neck place of ball pin main body, is become structure by " L of angle acute angle " tee section turns round 360 ゜, and namely its axial position is the structure that extend oblique outer top, with the pivot angle angle.The outer end of gland 4 and the radially clamping of ball seat 1 inwall, bottom end face contacts with ball cover 2 end faces, axial top end face contacts with dust protecting cap 6 bottom surfaces, and axial outside face contacts with dust protecting cap 6 inside faces, has the gap between the outer peripheral face of axial inside face and spheroid 2.Dust boot 6 is positioned at the axial top of ball seat 1 and is fixed on the ball seat 1 by jump ring 5.Dust protecting cap 6 and ball cover 2 inside all are added with grease, realize lubricated.Gland 4 contacts with ball cover 2 and dust protecting cap 6, has played the effect to ball cover 2 and dust protecting cap 6 axial location, and gland 4 is designed to " L " loop configuration, has guaranteed that ball pin assembly has enough pendulum angles in ball cover 2.
