Description
Technical field
This utility model belongs to technical field of automobile, relates to a kind of ball stud assembly.
Background technology
Ball stud assembly is one of of paramount importance parts in automobile suspension system, and it is primarily subjected to load transmission and steering-effecting in vehicle traveling process, and control stability, ride performance and safety to vehicle play a key effect.
Such as Chinese patent literature discloses a kind of ball stud assembly [application number: 200920302137.7 for automobile；Authorization Notice No.: CN201424051Y], it includes ball pin, dust cover, ball pin set and ball pin seat, ball pin seat it is set with in ball pin is overlapped, in the middle part of this ball pin seat, there is the spherical groove that the bulb with ball pin matches, ball pin is combined with the spherical groove in the middle part of ball pin seat by its bulb and ball pin is sleeved on ball pin seat, the upper end of ball pin set is provided with annular groove, dust cover is connected in the cannelure of ball pin set by the flange collar that its lower end is arranged, the upper connection end of ball pin stretches out the upper surface of dust cover, and the upper end of ball pin is provided with limit pin hole.
The setting by limit pin hole of the above-mentioned ball stud assembly for automobile, it is avoided that ball pin comes off in the process of moving, improve safety, its ball pin seat is made up of upper ball base and lower ball base, lower ball base is sleeved in the lower end of upper ball base, existing ball pin seat is also made of one, but it is the best all to there is wearability, the problem that service life is shorter, the spherical groove that the most in use there is ball pin seat is bigger, and the problem that the ball head of ball stud is less, now need the ball stud of large-size for assembling, but the length of the shaft of the ball stud of large-size is also the longest, assembling can be affected, needs re-work, operation inconvenience.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, it is provided that a kind of wearability is good, the ball stud assembly of length in service life.
The purpose of this utility model can be realized by following technical proposal: a kind of ball stud assembly, including ball seat, ball stud, ball bowl and dust cover, described ball seat offers spherical groove, described ball bowl is positioned in spherical groove, the ball head of described ball stud is loaded in ball bowl, the lower end of described dust cover is fixed on ball seat by collar, the bar portion of described ball stud stretches out dust cover and arranges, it is characterized in that, the inner surface of described ball bowl is fixed with in glass layer that is bowl-shape and that be coated with by ball head.
The setting by glass layer of this ball stud assembly, improves the tensile strength of ball bowl, hardness and toughness, and wearability is good, extends service life.
In above-mentioned a kind of ball stud assembly, described bar portion has conical surface section, and the described conical surface section diameter near top, bar portion is little, and the upper end of described dust cover is tightly contacted in conical surface section by jump ring.So conical surface section is big in the diameter of bar portion center, can play the effect stopping that dust cover upper end is pressed down against, it is to avoid dust cover upper end is difficult to reset.
In above-mentioned a kind of ball stud assembly, bottom described ball seat, riveting has egative film, is fixed with support pad in described ball seat, and the lower surface of described support pad is contacted with egative film, and the upper surface of support pad is supported in the bottom of ball bowl.So during actual manufacture, the assembly space of ball head can be adjusted by support pad, it is not necessary to select large-size ball stud, easy to operate, decrease cost.
In above-mentioned a kind of ball stud assembly, described egative film protrudes to the bottom of ball seat and makes to be formed between egative film and support pad shoe cream room, the charging hole of connection shoe cream room is offered in the middle part of described egative film, the middle part of described support pad offers the oil through of connection shoe cream room, described ball bowl bottom offers through hole one, the bottom of described glass layer offers through hole two, and described oil through, through hole one are connected with through hole two.During use, can be stored in shoe cream room by lubricant grease by charging hole, then be blocked by charging hole with plug, lubricant grease flow to, at ball head, be lubricated ball head through oil through, through hole one and through hole two, and high lubricating effect extends service life.
Compared with prior art, this ball stud assembly convenient processing and manufacture, low cost of manufacture, and also wearability is good, high lubricating effect, and service life is long.
