Abstract
The utility model discloses a lubricating device of an automobile steering ball joint. The lubricating device comprises a ball pin (2) with a ball head (4) and a ball seat (5), wherein the ball head (4) is rotatably engaged inside the ball seat (5). The lubricating device is characterized in that a vertical through hole (9) is axially arranged on the ball pin (2); a horizontal through hole (8) arranged on the ball head (4) is communicated with the vertical through hole (9); an oil nozzle (1) is connected with the end portion of the ball pin (2) far away from the ball pin (2); and the oil nozzle (1) is communicated with the vertical through hole (9). After the lubricating device adopts the structure, lubricating oil inside the ball seat is continuously supplemented as the mutually communicated vertical through hole and the horizontal through hole are arranged inside the ball pin, thereby strengthening wear resistance of a contact surface of the ball head and accordingly further prolonging the service life of the ball joint. Additionally, after the hole is arranged inside the ball pin, the weight of the whole ball pin is lightened.
Description
Technical field
The utility model relates to the auto parts and components field, specifically is the lubricating fitting that a kind of motor turning ball that is used for heavily blocking automobile and all kinds of engineering vehicle steering system connects.
Background technique
The divert ball joint head assembly is the parts of a key in the automobile steering system, and especially in second bridge of heavy-duty car, the steering ball joint also plays the reciprocal effect of the push-and-pull of servo-cylinder.At present, motor turning spherojoint assembly commonly used mainly is made up of joint, ball stud, dust-proof cover, ball seat, last ball bowl, following ball bowl, spring, bottom etc., earlier last ball bowl is linked in the ball seat, the ball head of ball stud is placed in goes up in the ball bowl, bottom is a tight fit in the ball seat and is positioned at the below of bulb, one end of spring is against in the bottom, the other end is against down on the ball bowl, make down ball bowl and bulb form Elastic Contact, load onto dust-proof cover at ball seat and bulb pin rod portion then, load onto joint at bulb pin rod afterbody.Because last ball bowl, following ball bowl and bulb all adopt rigid material to make, there is machining error inevitably, thereby when bulb and last ball bowl or following ball bowl cooperation, there is matching gap, abrasion differed when the surface of contact inequality will cause using, and enhance faster wear causes reduce the working life of whole spherojoint assembly, so generally in ball seat, inject lubricant oil in advance, thereby guarantee lubricating between bulb and last ball bowl or the following ball bowl.But there is following shortcoming in the lubricating fitting of the spherojoint assembly of this structure: because in ball tipping timing, before bottom, spring, following ball bowl are loaded onto, in ball seat, inject a certain amount of lubricant oil earlier, and then install down ball bowl, spring and bottom, the amount of the lubricant oil in the ball seat is along with the time of using slowly reduces like this, at last until using up, this moment, lubricant oil can not be compensated, thereby increased the friction ractor of sphere, aggravate the wearing and tearing of bulb surface of contact, caused the ball joint assembly shortening in working life.
The model utility content
Technical problem to be solved in the utility model is, providing a kind of can constantly add lubricant oil toward sphere, thus the lubricating fitting that the motor turning ball that can increase the service life connects.
For solving the problems of the technologies described above, the lubricating fitting that the motor turning ball that the utility model provides connects, comprise ball stud, ball seat with bulb, described bulb is rotatably assorted in ball seat, described ball stud axially is shaped on vertical through hole, be shaped on cross through hole on the described bulb, described cross through hole communicates with vertical through hole; Described ball stud is connected with oil nozzle away from the end of bulb, and described oil nozzle communicates with vertical through hole.
After adopting above structure, the utility model compared with prior art, have the following advantages: owing in ball stud, be shaped on vertical through hole and the cross through hole that is interconnected, therefore, when bulb rotates in ball seat and following ball bowl, lubricant oil constantly injects in the vertical through hole from the oil nozzle of ball stud end, arrive in the ball seat by cross through hole again, thereby flow in the gap of bulb and ball seat or following ball bowl, lubricant oil in the ball seat constantly is compensated, strengthen the wear resistance of bulb surface of contact, thereby prolonged the working life that ball connects more; In addition, in ball stud, after the punching, make the weight saving of whole ball stud.
As improvement, described ball stud also is shaped on the waist cross through hole that communicates with vertical through hole, and described waist cross through hole is positioned at the ball seat top.After adopting this structure, lubricant oil is flow in the contact gap of ball seat and bulb from the ball seat top, more can increase the wear resistance of sphere, more can prolong the working life of ball joint assembly.
Description of drawings

Fig. 2 is the structural representation of the lubricating fitting that connects of the utility model motor turning ball.
Wherein: prior art: 2 ', ball stud; 4 ', bulb; 5 ', ball seat; 6 ', bottom; 7 ', following ball bowl; 10 ', spring; 11 ', go up the ball bowl;
The utility model: 1, oil nozzle; 2, ball stud; 3, waist cross through hole; 4, bulb; 5, ball seat; 6, bottom; 7, following ball bowl; 8, cross through hole; 9, vertical through hole; 10, spring.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
The structural representation of the lubricating fitting that is connect by prior art motor turning ball shown in Figure 1 as can be known, it comprises ball stud 2 ', ball seat 5 ', last ball bowl 11 ', following ball bowl 7 ', spring 10 ' and the bottom 6 ' with bulb 4 ', the described ball bowl 11 ' of going up is linked in the ball seat 5 ', described bulb 4 ' is rotatably assorted in last ball bowl 11 ', bottom 6 ' is a tight fit in the ball seat 5 ' and is positioned at the below of bulb 4 ', described spring 10 ' one end is against in the bottom 6 ', the other end is against down on the ball bowl 7 ', described ball bowl 7 ' and bulb 4 ' Elastic Contact down.
The structural representation of the lubricating fitting that connects by the utility model motor turning ball shown in Figure 2 as can be known, it comprises ball stud 2, the ball seat 5 with bulb 4, described bulb 4 is rotatably assorted in ball seat 5.Described ball stud 2 axially is shaped on vertical through hole 9, is shaped on cross through hole 8 on the described bulb 4, and described cross through hole 8 communicates with vertical through hole 9.Described ball stud 2 is connected with oil nozzle 1 away from the end of bulb 4, and described oil nozzle 1 communicates with vertical through hole 9.Described ball stud 2 also is shaped on the waist cross through hole 3 that communicates with vertical through hole 9, and described waist cross through hole 3 is positioned at ball seat 4 tops.
The movement process that the utility model ball connects is such: turriform spring 10 compressions in the ball seat 5 produce axial pressure, axial pressure acts on the surface of contact of inner ball surface of bulb 4 outer spherical surfaces of ball stud 2 and ball seat 4, make it produce moment by swing or rotation ball stud, and the lubricant oil in the ball stud will automatically compensate on the surface of contact that ball connects each parts, thereby realize the acting of ball joint assembly, finally reach the function that ball joint assembly is realized universal and push-and-pull.
