Description
Technical field
The utility model belongs to the auto parts machinery technical field, relates to a kind of automobile connection fittings, particularly a kind of automobile ball head.
Background technique
Automobile ball head is to be used for the steering direction device of automobile and the link of deflecting roller, is one of accessory of automobile most critical, is the safety member that turns to and beat that guarantees steered wheel.Automobile ball head design and manufacture level are embodied directly on the cruising characteristic of steering wheel, and bad design and fabrication technology can produce steering wheel and become flexible, shakes or problem such as return difficulty, even also can cause steering failure.
Automobile ball head is made up of ball pin, spherical shell, dust-proof cover, ball seat and capping at present; The hatch frame of spherical shell is oblong; Can be implemented on the direction significantly the swing and crisscross on swing by a small margin; In order to solve the gap that wearing and tearing cause, between ball seat below and the spherical shell spring is installed.But the ball seat of this automobile ball head and spherical shell are metal friction, and be easy to wear, and the spherical shell place gets into water and sand easily in rugged environment in addition, causes product short working life.
People have made various designs and improvement to the problem that exists to automobile ball head, and some has also applied for patent, and for example the Chinese patent documents and materials disclose a kind of ball socket structure [application number: 200910144097.2 of automotive tie-rod end; Publication number: CN101603562A], it comprises ball pin, dust-proof cover, spherical shell, ball seat and the capping that is provided with the connection bulb, connects bulb and places in the spherical shell; The bar portion of ball pin stretches out from spherical shell; Ball seat is a loop configuration, is located between the bulb of inboard and ball pin of capping, spherical shell, and the end face of ball seat contacts with the inner side surface of capping; The material of ball seat is plastics, and the sealing configuration of whole plate is adopted in capping.
The ball socket structure of above-mentioned automotive tie-rod end is in when assembling, with the ball pin ball seat of packing into, ball seat packed in the spherical shell again, loads onto capping, rivet with special-purpose riveting machine then, is enclosed within on the spherical shell overlapping the dirt-proof boot of getting well little collar, puts big collar at last.Because capping adopts riveting machine to be connected with spherical shell,, can destroy the surface treatment protective layer of product like this so the textured surface of arc can appear in riveted joint place; Riveted joint causes the permanent deformation of metal in addition; So can't change the part in the spherical shell, can only disposablely use, can not keep in repair.
Summary of the invention
The purpose of the utility model is to the problems referred to above that exist in the existing technology, and a kind of automobile ball head of protecting surface-treated layer, detachable convenient for maintaining is provided.
The purpose of the utility model can realize through following technical proposal: a kind of automobile ball head; Comprise housing, ball seat, shrouding and be shaft-like ball pin with receiving cavity; The inner of described ball pin is the receiving cavity that sphere-like and this inner are positioned at housing; Housing is stretched out in the outer end of ball pin, and described shrouding is fixed between the inner of bottom and shrouding and ball pin of housing and is fixed with ball seat, it is characterized in that; The inwall that described housing is positioned at offers annular locating slot, and the edge of described shrouding embedded in the locating slot when described shrouding and housing bottom were connected.
Before shrouding in this automobile ball head was unassembled, that arches upward slightly in the middle part of shrouding is was tabular.During assembling, ball pin, ball seat are packed in the housing, afterwards shrouding is placed the bottom of housing, make shrouding press deformation, the edge of shrouding is embedded in the locating slot of housing bottom, so just accomplished assembling through press, easy to assembly quick.In use for some time, after ball seat or the wearing and tearing of ball pin, press the outer end of ball pin; Active force is delivered on the shrouding through the inner, the ball seat of ball pin, and shrouding is ejected from the locating slot of housing, and this moment can be according to actual conditions; Ball pin or ball seat are changed, are ressembled good shot pin, ball seat afterwards, with new shrouding with housing bottom shutoff again; So just, need not the integral replacing automobile ball head, reduced user cost.In addition since housing do not rivet distortion, so the electrophoresis of surface of shell, the lacquer these surface treatment protective layers can not be destroyed.
In above-mentioned a kind of automobile ball head, be provided with the elastic component that ball seat is contacted with the inner of ball pin all the time between described shrouding and the ball seat.Elastic component provides elastic force to make ball seat contact with the inner of ball pin all the time, keeps the motion moment of torsion of bulb, has guaranteed the performance accuracy of this automobile ball head.
In above-mentioned a kind of automobile ball head, described elastic component is spring or dish spring.One end of spring or dish spring acts on the shrouding, and the other end acts on the ball seat.
In above-mentioned a kind of automobile ball head, be fixed with the dirt-proof boot of the outer end of passing the ball pin on the described housing, an end of described dirt-proof boot is anchored on the top of ball pin through garter spring, and the other end of dirt-proof boot is clamped in the top of housing through snap ring.The setting of dirt-proof boot avoids silt and water to enter into housing, and good airproof performance has improved working life.
In above-mentioned a kind of automobile ball head, described ball seat adopts powder metallurgy to process.Ball seat adopts copper molybdenum powder metallurgy to process, and the wear resistance of ball seat is good, long service life.
Compared with prior art, a kind of automobile ball head of providing of the utility model has the following advantages:
1, shrouding and housing are connected through locating slot in this automobile ball head, and be easy to assembly like this, and replaceable ball pin or parts such as ball seat, spring, convenient for maintaining, and user cost is low.
2, the bottom of this automobile ball head middle shell need not to rivet processing, so housing do not rivet distortion, so the electrophoresis of surface of shell, these surface treatment protective layers of lacquer and can not be destroyed.
3, the good airproof performance of dirt-proof boot in this automobile ball head avoids silt and water to enter into housing, has improved working life.
4, ball seat adopts powder metallurgy to process in this automobile ball head, and the wear resistance of ball seat is good, long service life.
