Abstract
The utility model provides a high-efficiency lubrication sealing ball pin which comprises a casing, a ball cup arranged in the casing and a ball head connected with the ball cup in a matched manner. The ball pin is characterized in that an upper sealing part is arranged on an oil storage chamber formed between the ball cup and the casing, and a lower sealing part is arranged at the lower end of the ball head. The utility model can effectively prevent the lubricant during the work from leaking, and meanwhile, prevent the earth water and the foreign impurities outside from entering to lead to wear and enables the stressed part to be always in the lubricated state, thereby thoroughly overcoming the defects of easy wear due to the poor lubrication of the prior ball pin, in addition, a buffer film with protection effect is naturally formed between the ball cup and the ball head, therefore, the service life of the ball pin is greatly prolonged. The utility model has the advantages of simple structure, easy processing and production, obvious lubricating effect, good sealing performance, low cost, flexible rotation, accuracy, sensitive operation, high stability and reliability, and the like.
Description
Technical field
The utility model relates to a kind of ball stud, especially a kind of ball stud with efficient lubrication and seal effect.
Background technique
Turn in big compact car, tractor, engineering machinery etc., in the suspension system, all will use and turn to ball stud flexibly, the frequent simultaneously ball stud that rotates also is parts easy to wear, after use one sets a term, must change, otherwise will bring significant impact traffic safety.The ball stud that uses can be divided into two kinds by internal structure at present: a kind of is to utilize spring force to promote the ball bowl, and the wearing clearance with between compensation ball bowl and the bulb can closely cooperate ball bowl and bulb.But this structure can not solve lubricated problem, is in the dry grinding state substantially between bulb and the ball bowl, and dry and astringent and have some setbacks during rotation, frictional force is bigger, serious wear, spring fatiguability and can fractureing, and complex structure simultaneously, cost height, poor reliability; Another kind is that the working of plastics integral body with moulding is wrapped on the bulb, to replace hard metal ball bowl.Though its structure is comparatively simple, and is cheap, when using in the steering suspension of inclement condition, working of plastics is easily stressed and be out of shape, thereby influences its working life.Also there are deficiencies such as waterproof and dustproof poor performance in existing ball stud.The basic reason that causes ball stud to damage is: under frequent stressed situation between bulb and the ball bowl, exist serious insufficient lubrication between its internal friction face, and this insufficient lubrication, except outside the Pass the performance with oiling agent itself has, more priorly be: because sealing is bad, often cause oiling agent to leak, time one is long, get back to the dry grinding state again, this of short duration lubricating, be difficult to prolong the working life of ball stud beyond doubt, poor sealing also can make muddy water, impurity etc. enter simultaneously, thus aggravation wearing and tearing.Therefore, be necessary fully prior art is improved.
Summary of the invention
Bad for overcoming the lubrication and seal that prior art exists because of force part between ball stud and the ball bowl, and bring the ball stud wearing and tearing big, lack working life, the high deficiency of cost, the utility model provides a kind of lubrication and seal effective ball stud.
The utility model is finished by following technical proposal: a kind of efficient lubrication and seal ball stud, comprise housing, place the ball bowl in the housing, the bulb that connects with the ball bowl, it is characterized in that being provided with Sealing on the accumulator that forms between ball bowl and the housing, and be provided with lower seal in the bulb lower end, to improve sealability.
The described Sealing of going up is made as sealed bolster plate, perhaps seal ring, perhaps oil sealing.
Described sealed bolster plate shape is made as circle, ellipse, rectangle or the polygonal that adapts with housing, to strengthen sealing effect.
Described lower seal is arranged in the following accumulator that forms between bulb and the ball bowl, so that under the situation that guarantees sufficient lubrication, improves sealability.
Described lower seal is made as sealed bolster plate, perhaps seal ring, perhaps oil sealing.
The internal surface of described sealed bolster plate is made as the concave surface that adapts with the bulb lower end, to guarantee their fluid-tight engagement.
The described Sealing of going up is provided with cover plate, so that the force part is in the lubricated state all the time.
The utility model compared with prior art has following advantage and effect: adopt such scheme; promptly Sealing is being set on the accumulator that forms between ball bowl and the housing; after simultaneously in the following accumulator that between the bulb of bulb lower end and ball bowl, forms lower seal being set; can prevent effectively that the oiling agent in the work from leaking; prevent outside muddy water simultaneously; impurity enters and aggravates to wear and tear; allow this force part be in all the time in the lubricated state; many deficiencies such as easy to wear that existing ball stud brings because of insufficient lubrication have fundamentally been solved; oiling agent forms the buffer film with protective action naturally between ball bowl and bulb in addition; greatly prolonged the working life of ball stud; the utlity model has simple in structure; be easy to processing; lubrication effect is outstanding; good seal performance, cost is low, rotates flexibly; accurately; manual dexterity, stability; the reliability advantages of higher.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The efficient lubrication and seal ball stud that the utility model provides, comprise housing 4, place the ball bowl 2 in the housing 4, the bulb 1 that connects with ball bowl 2, wherein on forming between ball bowl 2 tops and the housing 4, be provided with circular upper sealing panel 6 on the accumulator 5, to improve sealability, cover plate 7 is established in the top of upper sealing panel 6, after allowing oiling agent flow the force part is lubricated, set sealing gasket 3 in the following accumulator 13 that forms between bulb 1 lower end and ball bowl 2, the internal surface of sealing pad 3 is made as the concave surface that matches with bulb 1 lower end, so that under the situation that guarantees sufficient lubrication, improve sealability, be provided with ball bowl bracket 11 in the inboard of last accumulator 6.
Claims (6)
1, a kind of efficient lubrication and seal ball stud comprises housing, places the ball bowl in the housing, with the bulb that the ball bowl connects, it is characterized in that being provided with seal plates on the accumulator that forms between ball bowl and the housing, and is provided with lower seal in the bulb lower end.
2, efficient lubrication and seal ball stud according to claim 1 is characterized in that the described Sealing of going up is made as sealed bolster plate, perhaps seal ring, perhaps oil sealing.
