The assembly includes a ball pin which has a global middle part and a friction pair outer ring which composes a friction pair with the spherical part. The assembly is characterized in: the spherical outer surface of the ball pin is a smooth surface or is disposed with an oil storage section; the outer ring of the friction pair is a ball casing shaped integrated structure with openings on both ends; and the outer surface of the friction pair outer ring is provided with an elastomer layer; Beneficial effects: the friction pair outer ring is an integrated structure, thereby the assembly of the utility model greatly simplifies structure, and improve work reliability and stability; the ball pin can work without oil groove on the spherical part, thereby lubrication is omitted; and the assembly of the utility model an be used in completely opened mode in harsh environment.
Description
Technical field
The utility model relates to a kind of automobile slide ball pin assembly, and relating in particular to a kind of friction pair outer ring is an integrally-built novel slide ball pin assembly.
Background technique
The distance rod assembly of heavy goods vehicle balance rear-pendant is the important stressed member of suspension system, and its higher spoilage is the problem of car load and component manufacturer headache always, and the main position of damage is at ball pin assembly.The tradition ball pin assembly adopts the polyurethane sliding motion structure, and the ball pin of this structure is very short in heavy duty and following life-span of impulsive load, and reliability is relatively poor; Usually adopt the ball pin assembly of whole sulfuration (rubber or polyurethane) structure now, the working life of this ball pin is longer than conventional construction, but the ball pin of whole sulfuration reversed, under the external force comprehensive functions such as deflection and extruding, the rubber of ball pin comes unstuck easily, tears and extrudes, finally cause ball pin failure, the another one defective of this structure is exactly that ball pin angle can't be adjusted by hand, and general assembly is difficulty comparatively, so also there is certain narrow limitation in this structure.
The ball pin assembly of present rubber material, reverse with the deflection operating mode under shearing force, tensile force and the partial high pressure of bearing can make ball that pin takes place to damage.Existing glide ball pin also must have lubricant oil to be lubricated, and just can work preferably.
Summary of the invention
The utility model has overcome the shortcoming of above-mentioned technical problem, and it is integrally-built novel slide ball pin assembly that a kind of not lubricating oil filling and friction pair outer ring are provided.
For achieving the above object, the utility model has adopted following technological scheme:
Novel slide ball pin assembly of the present utility model, comprise the position, intermediate portion be spheroid the ball pin and with the partner friction pair outer ring of friction pair of the spheroid of ball pin, its specialization is: the spheroid outer surface of described ball pin is a smooth flat or is provided with the oil storage mouth, described friction pair outer ring is the integrative-structure of the spherical shell shape of both ends open, and described friction pair outer ring outer surface is provided with one deck elastomer; Aforesaid friction pair outer ring is designed to integrative-structure, the functional reliability that has greatly improved this assembly has also been simplified the structure of assembly greatly, the spheroid outer surface at described ball pin middle part can process oil storage tank and also can be designed to smooth sphere, can cut down greatly the ball pin reverse with the deflection operating mode under shearing force, tensile force and the partial high pressure of bearing, avoided the damage of ball pin assembly effectively.
Novel slide ball pin assembly of the present utility model, described elastomeric two end part are provided with the end cap with ball pin coaxial line, and the purpose that end cap is set is to make that after ball pin assembly installed, elastomer was in confined state.
Novel slide ball pin assembly of the present utility model, described end cap and elastomer are structure as a whole through being sulfided into, and the elastomer sulfuration of described end cap and friction pair outer ring is structure as a whole, and makes that ball pin assembly of the present utility model is more firm.
Novel slide ball pin assembly of the present utility model, the outer side surface of described end cap be flatness, tubaeform or the band turnup structure shape, the shape of end cap is indefinite, can be designed to different shape, for example is designed to shape with flange and can realizes when mounted and the cooperating of seal ring.
Novel slide ball pin assembly of the present utility model, described elastomeric material is rubber or polyurethane.
Novel slide ball pin assembly of the present utility model, described friction pair outer ring is that metallic material and its internal surface are coated with rub resistance material, before extrusion modling,, make bearing be implemented in that friction factor also can be minimum under the unlubricated situation to applying rub resistance material as the blank of friction pair outer ring working surface.
The beneficial effects of the utility model are: (1) described friction pair outer ring is structure as a whole, and has simplified structure of the present utility model greatly and has improved the reliability and stability of its work; (2) spheroid of ball pin can not be provided with oil storage tank, has saved lubricated; (3) ball pin assembly of the present utility model can use under wide-open rugged environment.
