Background technique
At present, vehicle is transport facility the most widely, its braking ability plays vital effect to traffic safety, automobile pull rod joint mechanism is the important accessory in auto steerer, more be related to the Security of automobile, once automobile pull rod joint mechanism is impaired, not only make the steering gear operationally noise increase, and loosening of steering wheel can be caused, shake and return difficulty, serious have impact on traffic safety, but all as easy as rolling off a log wearing and tearing of most automobile pull rod joint mechanism on market, cause its working life shorter, easy wearing and tearing mainly because the material of ball seat, the ball seat that common iron is produced is all impact briquetting, and impact briquetting is difficult to the size and dimension precision ensureing ball seat, therefore this being difficult to ensures that high-precision ball stud carries out easily causing wearing and tearing in the process swung in ball seat, shorten the life-span of joint mechanism, although moreover be have now people in automobile pull rod joint mechanism, smeared grease, but cannot ensure that inner body is in lubricating status for a long time, once there is no grease lubrication effect, ball stud can be caused to swing jerky, more easily accelerate the wearing and tearing of pull bar, have a strong impact on the working life of joint mechanism.
Model utility content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide one effectively can improve working life, reduces the automobile ball pin rod head device of pull bar wearing and tearing.
For achieving the above object, the utility model adopts following technological scheme:
A kind of automobile ball pin rod head device, comprise ball stud and spherical shell, the pin rod that described ball stud comprises bulb and is connected with described bulb, described pin rod comprises the first pin rod be connected with described bulb and the second pin rod be connected with described first pin rod, described bulb is fixedly mounted on the inside of described spherical shell, the inside of described spherical shell is also provided with the ball seat that is close to bulb, the upper surface of described spherical shell is provided with perforate, the surface of described bulb is provided with oil groove, described perforate is connected with described oil groove, the bottom package of described spherical shell has an end cap mated with it, spring is provided with between described ball seat and end cap, described second pin rod is bolted with a hexagon nut, the upper edge place of described hexagon nut is provided with opening, described second pin rod is provided with the through hole corresponding with described opening, described through hole is interspersed with the latch be fixed on by described hexagon nut on described second pin rod, described first pin rod is socketed with the dust-proof cover matched with described spherical shell.
Preferably, the inwall of described perforate is provided with screw thread, and described perforate is provided with a bolt matched with it.
Preferably, described oil groove is semi-circle.
Preferably, the diameter of described oil groove is 14mm.
Preferably, described ball seat is No. 45 steel ball seat.
The beneficial effects of the utility model are as follows: this automobile ball pin rod head device effectively can improve working life, reduce pull bar wearing and tearing.Namely by being provided with the tapped hole leading to oil groove, can grease be increased in time voluntarily ball pin rod head, reduce the degree of wear of automobile ball pin pull bar, extend the working life of ball pin pull bar, solve simultaneously existing automobile pull rod also exist beat direction dumb, improve traffic safety.The inwall of perforate is simultaneously provided with screw thread, and is provided with the bolt matched with it, effectively can prevent entering in oil groove of dust.Ball seat is No. 45 steel ball seat simultaneously, effectively can improve the antiwear property of ball seat.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the better embodiment of a kind of automobile ball pin rod head of the utility model device.
Accompanying drawing illustrates: 1, hexagon nut; 11, latch; 2, ball stud; 21, bulb; 22, the first pin rod; 23, the second pin rod; 3, dust-proof cover; 4, ball seat; 5, end cap; 6, spherical shell; 7, spring; 8, oil groove; 9, perforate.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
Refer to Fig. 1, the utility model relates to a kind of automobile ball pin rod head device, its better embodiment comprises ball stud 2 and spherical shell 6, the pin rod that ball stud 2 comprises bulb 21 and is connected with bulb 21, pin rod comprises the first pin rod 22 be connected with bulb 21 and the second pin rod 23 be connected with the first pin rod 22, bulb 21 is fixedly mounted on the inside of spherical shell 6, the inside of institute's spherical shell 6 is also provided with the ball seat 4 that is close to bulb 21, the upper surface of spherical shell 6 is provided with perforate 9, the surface of bulb 21 is provided with oil groove 8, perforate 9 is connected with oil groove 8, the bottom package of spherical shell 6 has an end cap mated with it 5, spring 7 is provided with between ball seat 4 and end cap 5, second pin rod 23 is bolted with a hexagon nut 1, the upper edge place of hexagon nut 1 is provided with opening, second pin rod 23 is provided with the through hole corresponding with opening, through hole is interspersed with the latch 11 be fixed on by hexagon nut 1 on second pin rod 23, first pin rod 22 is socketed with the dust-proof cover 3 matched with spherical shell 6.
Before automobile ball pin rod head device does not also load onto dust-proof cover 3, curing grease is added by the perforate 9 being positioned at spherical shell 6 surface, even if after the grease therefore just added at first constantly touches down between the components and lost efficacy, wearing and tearing to each other are also made to accelerate without the need to worrying in-house part to be no longer in lubricating status.Because the grease be added in oil groove 8 can constantly be exuded to bulb 21 surface under ball stud 2 swings, and the grease on bulb 21 surface also can cover other part surfaces in constantly contacting with other parts, automobile ball pin rod head device is enable to be in lubricating status for a long time.When curing grease is used up, by the bolt on spherical shell 6 surface of outwarding winding, when adjusting ball stud 2 for vertical level, at this moment one of oil groove 8 correct and be connected with perforate 9, curing grease is injected to 8 li, oil groove by perforate 9, slow down the wearing and tearing between in-house part to the full extent, extend the working life of automobile pull rod joint mechanism.
The inwall of perforate 9 is provided with screw thread, and perforate 9 is provided with a bolt matched with it.Arranging of bolt can prevent external dust or remaining foreign matter from entering spherical shell 6 inside.Oil groove 8 is diameters is 14mm semi-circle, and the size of certain diameter can also be that other are not more than the value of the diameter of bulb 21.
Ball seat 4 is No. 45 steel ball seat, namely ball seat 4 is No. 45 steel forging moldings, and make through Overheating Treatment, fine finishing, size and the accuracy to shape of ball seat 4 can be ensured to the full extent, make the most precision of the assembling between ball seat 4 and other parts, prevent the generation owing to assembling the situation that discomfort causes the degree of wear to increase, extend the working life of automobile pull rod joint mechanism, ensure that travel safety.
For a person skilled in the art, according to technological scheme described above and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection domain of the utility model claim.
