Abstract
The utility model discloses an automobile steering ball pin. The automobile steering ball pin comprises a ball pin body. The ball pin body comprises a cone, a threaded rod connected to one end of the cone and connected with a steering pull rod, and a ball end face connected to the other end of the cone. A groove is formed in the ball end face, and the depth of the groove is larger than the radius of the ball end face. By adopting the structure, the automobile steering ball pin has the advantages that pressure required in the cold extruding process is reduced, blank accuracy is improved, the service life of a mold is prolonged, and machining procedures are simplified; materials are saved, the requirement for the power of extruding equipment is low, and further the service life of the automobile steering ball pin is prolonged in the using process.
Description
Technical field
The utility model relates to automobile steering system technology, particularly a kind of automotive steering ball pin.
Background technology
Between the wheel of automobile and axletree, be interconnective by cue ball pin, simultaneously between wheel and deflecting bar also with turning to ball pin to be connected, existing cue ball pin and to turn to ball pin be to design a thread rod in path one end of taper radius stay, a solid sphere is designed in one end, large footpath of taper radius stay, especially the surface configuration of solid sphere part will have quite high dimensional accuracy and form accuracy, must just can reach requirement through fine grinding, this has just brought very large difficulty to processing, by existing general technology level, to manufacture blank by the mode of forging and stamping, then after tempered processing, finish turning moulding, again through quenching by row fine grinding, because forging blank precision is very low, so the stock left for machining of finish turning is larger, cause material, man-hour, artificial serious waste.For addressing this problem, be mostly to improve from processing technology aspect at present.More advanced improvement project of stage is to adopt the cold extruding mode blank that manufactures a product now, though this method can improve semifinished product precision, but for guaranteeing that material can be full of squeezing dies die cavity, must strengthen the injected volume of material, during matched moulds, unnecessary material produces serious burr along squeezing dies parting line place, both to following process, brought difficulty, affect again semifinished product precision, cause material serious waste simultaneously, because ball pin is solid sphere, during extruding spheroid, need larger pressure in addition, must select the extrusion dies that high-performance extrusion equipment and intensity are very high.Although so this technique can improve semifinished product precision, but still can not be satisfactory, and have increased the input of equipment and mold.
Utility model content
Technical problem to be solved in the utility model is, for the deficiencies in the prior art, provides a kind of pressure required while reducing cold extruding, improves semifinished product precision, increases die life, simplifies the automotive steering ball pin of machine up operation simultaneously.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of automotive steering ball pin, comprise ball pin body, described ball pin body comprises centrum, be connected to centrum one end the thread rod being connected with steering track rod, be connected to the pommel face of the centrum other end, described pommel face is provided with groove, and the degree of depth of described groove is greater than pommel radius surface.
Described groove diapire area is greater than the aperture area of described groove, and described slot opening is arc-shaped transition to the cell wall of groove diapire.
The utility model adopts said structure, has the following advantages: required pressure while 1, reducing cold extruding, improve semifinished product precision, and increase die life, simplify machine up operation simultaneously; 2, save material, not high to extrusion equipment power requirement, further improve the product life-span in use.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Fig. 1 is structural representation of the present utility model;
In Fig. 1,1, centrum; 2, thread rod; 3, pommel face; 4, groove.
The specific embodiment
An automotive steering ball pin, comprises ball pin body as shown in Figure 1, it is characterized in that: described ball pin body comprises centrum 1, be connected to centrum 1 one end the thread rod 2 being connected with steering track rod, be connected to the pommel face 3 of centrum 1 other end, and its external diameter is ￠ 25.Described pommel face 3 is provided with groove 4, and the degree of depth of groove 4 is greater than pommel face 3 radiuses.Groove is not less than 3mm.
Ball pin is a kind of important component part of automobile steering system, and its Main Function is to transmit force and moment between wheel and vehicle frame.Control arm or propelling rod are conventionally realized and being connected with other part by ball pin.These joints should meet following requirement: have less friction; Do not need to be maintained during use, to reduce use cost or to reduce labour intensity; Connection should have certain elasticity;
Adopt this structure can save in a large number metallic material, store grease volume and increase lubricating between raising ball pin and ball seat, pressure in the time of can reducing cold extruding in process of manufacture, to cold extruding press power requirement, die life improves, and actv. improves semifinished product precision, thereby simplifies machining process, enhance productivity and the stability of product, be especially applicable to producing in enormous quantities.
Required pressure when ball pin adopts this structure to reduce cold extruding, improves semifinished product precision, increases die life, simplifies machine up operation simultaneously.The advantage of this patent is, it saves material, not high to extrusion equipment power requirement, and die life increases, and semifinished product precision improves, and simplifies mechanical processing technique, further improves the product life-span in use.
The production technology of this ball pin is: adopt cold extrusion method by bar undergauge, pier cone and extruding, undergauge forms the blank of screw rod, through pier taper, become cone, then carry out essence and squeeze formation pit spheroid, can manufacture pit ball pin blank, by current domestic cold-extrusion technology level, this semifinished product precision can reach requirement completely, after turning back taper, and can direct smart face, thereby greatly reduce machinework, enhance productivity.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as the various improvement that adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
