Abstract
The utility model discloses a vehicle globe joint structure, which comprises a ball-and-socket joint, a ball cup, a tie-in, a dust preventive cover and a clip ring. The utility model is characterized in that the ball cup is a one-molding plastic piece, the inner diameter of the lower part of the inner wall of the ball cup is smaller than the sphere diameter of the ball-and-socket joint, the plastic ball cup undergoes obliged transformation, after the ball joint is assembled as required, to produce an inner force that keeps supporting the ball-and-socket joint upwardly and tightly to maintain the good matching status between the ball-and-socket joint and the ball cup. The utility model adopting the one-molding plastic ball cup to replace the original piece with an upper and a lower separated parts, not only simplifies the structure of the product, but also ameliorates the friction tolerance feature between the ball-and-socket joint and the ball cup, with raised life span of the product.
Description
Technical field
The utility model relates to the auto parts machinery technology, is specifically related to a kind of automobile-used ball-joint structure.
Background technique
Ball-joint is to use more mechanical structured member in the auto parts machinery, is usually used in positions such as suspension arms, knuckle.Existing automobile-used ball-joint generally is made of ball pin, upper ball base, lower ball base, joint, clearance compensating spring, bottom and dust-proof cover etc., and wherein ball pin and ball seat are metallic article.Ball-joint in the course of the work between ball pin and the ball seat mutually friction be easy to wearing and tearing, " becoming flexible " phenomenon appears, " becoming flexible " phenomenon appears for fear of ball-joint, generally adopt the method that clearance compensating spring is set in the existing automobile-used ball-joint in the ball-joint structure, rely on spring tension to make ball pin and ball seat be in " closely " contact condition all the time, thereby reach the effect of improving the ball-joint usability.But although rely on the effect of clearance compensating spring can improve the usability of ball-joint relatively, but working life is still not long, and complex structure, overall volume are big.
The model utility content
The purpose of this utility model provides a kind of simple in structure, overall volume is less, working life is relatively long automobile-used ball-joint structure.
The technical solution of the utility model is:
Automobile-used ball-joint structure is made of ball pin, ball seat, joint, dust-proof cover, collar, bottom, it is characterized in that: described ball seat is a plastics once-through product, and ball seat inwall underpart internal diameter is less than the spherical diameter of ball pin.
Ball seat inwall underpart internal diameter is less than the effect of the spherical diameter of ball pin, after the ball-joint structure is assembled on request, the plastics ball seat is subjected to imposed deformation and can produces all the time to the internal force that tightens holder ball pin, make and keep good cooperating between ball pin and the ball seat, as seen this is identical with clearance compensating spring role in the existing product, so the utility model need not to use clearance compensating spring.
In order to increase the intensity of ball seat lower end plastic thin wall structure, the outer surface in its underpart is provided with some stiffening ribs.
Because the plastics ball seat matches with the Metal Ball pin, wearing and tearing between the two are very little, and it is few to consume lubricant grease, once fill with grease and can satisfy long-term use when the assembling ball-joint, therefore need not as the reason product pump nozzle to be set on bottom.
The utility model adopts plastics once-through ball seat to substitute the ball seat of the upper and lower split in the existing product, has both simplified product structure, has improved the wear-resisting property between ball pin and the ball seat again, has improved working life.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, automobile-used ball-joint structure is made of ball pin 1, ball seat 2, joint 5, dust-proof cover 4, collar 3 and collar 6, bottom 7, fills with lubricant grease 8 in the ball-joint Seal cage.Wherein ball pin 1 is a Steel Work, and ball seat 2 is a plastics once-through product.Even still can keep good fit state in order to make between ball pin 1 and the ball seat 2 under the situation of slightly wearing and tearing, the design size of ball seat 2 inwall underpart internal diameters should be less than the spherical diameter of ball pin 1.Ball seat 2 inwall underpart internal diameters are that less than the effect of the spherical diameter of ball pin 1 after the ball-joint structure was assembled on request, plastics ball seat 2 was subjected to imposed deformation, can produce all the time to the internal force that tightens holder ball pin 1, make good the cooperating of maintenance between ball pin 1 and the ball seat 2.In order to increase the intensity of ball seat 2 lower end plastic thin wall structures, the outer surface in its underpart is provided with equally distributed six stiffening ribs.
Claims (3)
1. an automobile-used ball-joint structure is made of ball pin, ball seat, joint, dust-proof cover, bottom, collar, it is characterized in that: described ball seat is a plastics once-through product, and ball seat inwall underpart internal diameter is less than the spherical diameter of ball pin.
2. automobile-used ball-joint structure according to claim 1 is characterized in that: described one-time formed plastics ball seat, the outer surface of its underpart is provided with some stiffening ribs.
3. automobile-used ball-joint structure according to claim 1 is characterized in that: do not establish pump nozzle on the described bottom.
