Abstract
The utility model relates to a novel ball seat of a ball pin, which comprises a ball main body (2), the ball pin (5), a ball seat body (1) and a dust cover (6); the ball seat body (1) is arranged in the ball main body (2); the head part (4) of the ball pin is in contact with the ball seat body (1); bulges (3) or concave pits are arranged on the inner surface of the ball seat body (1). The novel ball seat solves the problems of short service life and too high use cost of a conventional product, thereby having a wide market prospect.
Description
Technical field
The utility model relates to the automobile mechanical technical field, is specially a kind of Novel ball pin ball seat.
Background technique
At present, the ball-head tension rod in automobile steering system, will have the design of ejecting force when increasing load, and the restriction of dial-out power will be arranged when vibration.The original design service life of this product is that the continuous pivoting friction of ball stud in the plastics ball seat will reach 1,000,000 times, and the surface of contact of sphere and ball seat will reach more than 60%.Owing to not storing grease in ball seat, be put on that oil on ball pin can run low very much and residual spheroid in drier oil fat become Fen Droplets heavy wear ball seat, and dust-proof cover is after use a period of time, dust and sewage can enter in ball seat the wearing and tearing of accelerating ball seat when ball pin swing work, can not reach like this 1,000,000 times of life-span of design the working life of ball seat far away.
Summary of the invention
The utility model easily weares and teares for the ball seat that solves in existing automobile steering system, and the technical problem that working life is short, provide a kind of Novel ball pin ball seat, to overcome the deficiencies in the prior art.
For solving the problems of the technologies described above the technical solution of the utility model be: a kind of Novel ball pin ball seat, comprise bulb main body, ball stud, ball seat, dust-proof cover, described ball seat is arranged in the bulb main body, described ball stud head contacts with ball seat, it is characterized in that: described ball seat internal surface is provided with projection or pit.
Described projection be shaped as spherical or conical.
Described pit be shaped as circle.
The height of above-mentioned projection is 0.3-0.8mm.
The degree of depth of above-mentioned pit is 0.3-0.8mm.
The beneficial effects of the utility model are, the utility model is under the function of product itself and the constant prerequisite of attribute, by being set at the ball seat internal surface, projection and pit increase the oil storage space of ball seat, make the swing of product more smooth, the conduit of the formation between ball point and ball point can increase a large amount of oil storage space, oil residue and the outside dust foreign material that enter that become powder Droplets of also attracting deposits can be discharged to the duct, bottom along with swinging, make ball seat be difficult for being worn, increase the 2-3 in original working life doubly.Recessed round pool principle is the same, but oil residue and the outside dust foreign material that enter that become Fen Droplets of attracting deposits can be kept in recessed round pool, the utility model all small sphere of exterior rearviews by setting up oil storage space and projection with ball stud the sphere friction reduced the friction factor of bulb and ball seat, can significantly improve product working life, have wide popularization space.
Description of drawings
Fig. 1 is the utility model embodiment 1 structural representation.
In figure, 1 is ball seat, and 2 is the bulb main body, and 3 is projection, and 4 is the ball stud head, and 5 is ball stud, and 6 is dust-proof cover.
Specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.As shown in Figure 1, a kind of Novel ball pin ball seat, comprise bulb main body 2, ball stud 5, ball seat 1, and described ball seat 1 is arranged in main body 2, ball stud head 4 contacts with ball seat 1, and described ball seat 1 internal surface is provided with globule or the small cylinder 3 that height of projection is 0.5mm.
The utility model will be further described below in conjunction with accompanying drawing.A kind of Novel ball pin ball seat, comprise bulb main body 2, ball stud 5, ball seat 1, and described ball seat 1 is arranged in main body 2, and ball stud head 4 contacts with ball seat 1, and described ball seat 1 internal surface is provided with the circular pit that cup depth is 0.6mm.
Because ball stud the head 4 and globule of ball seat 1 protrusion or the ball point smooth surface of small cylinder 3 becomes relative rolling friction, ball seat and ball stud are worn hardly, and a large amount of oil storage space coefficient of reducing friction is arranged, can increase the service life, the principle of recessed round pool the same and also can the attract deposits oil residue that becomes Fen Droplets and the outside dust foreign material that enter make foreign material do not participate in wearing and tearing to ball seat and ball stud increase working life 3-5 doubly.
The above; it is only the better embodiment of the utility model; but the utility model protection domain is not limited to this; be equal to according to the technical solution of the utility model and inventive concept thereof any relief pattern of replacing or changing, within all should being encompassed in protection domain of the present utility model.
Claims (5)
