Abstract
The invention discloses an abrasion-resisting automobile hub with an oil nipple. The abrasion-resisting automobile hub comprises a hub body, wherein one end of the hub body is provided with an integral flange, and a rolling path matched with a bearing inner ring is arranged at the transition position of the flange and the hub body. The abrasion-resisting automobile hub is characterized in that an inner abrasion-resisting sleeve and an outer abrasion-resisting sleeve are fixedly sleeved in the hub body, an inner hole of the inner abrasion-resisting sleeve and the annular outer wall of the outer abrasion-resisting sleeve are in matched conical shapes, and the inner abrasion-resisting sleeve and the outer abrasion-resisting sleeve form a cylindrical shape through interference fit. An oil filling hole is formed in the position of the hub body corresponding to the rolling path, and the oil nipple is installed in the oil filling hole. The inner abrasion-resisting sleeve and the outer abrasion-resisting sleeve which are in interference fit are added in the hub body, so that the abrasion resistance of the automobile hub is strengthened. In addition, lubricating oil is filled into the hub by using the oil nipple with the special structure at regular periods, and the lubricating effect is good.
Description
Technical field
The present invention relates to the automotive hub structure, specifically a kind of wear-resistant automotive hub with oil nozzle.
Background technology
Wheel hub is the important component part of automobile, and motor tire itself is software, and the drum-shaped structure of wide support tire in tire just is wheel hub.Because bearing and wheelboss flange are installed together mutually, there is error in installation process, cause wheel hub and bearing size precision low.So, the direct raceway that coordinates with bearing inner ring of design on present automotive hub, make between wheel hub and bearing easier for installation, the increase dimensional accuracy.But, exist defect easy to wear, that lubricity is bad etc.
Summary of the invention
The present invention, in order to make up the defect in prior art, provides a kind of wear-resistant automotive hub with oil nozzle, and it has good resistance to abrasion and good lubricant effect.
For addressing the above problem, the present invention adopts following technical scheme:
A kind of wear-resistant automotive hub with oil nozzle, include hub body, one end of hub body is provided with the flange of one, the intermediate location of flange and hub body is provided with the raceway coordinated with bearing inner ring, it is characterized in that: in described hub body, fixed cover is equipped with inside and outside wear-resistant sleeve, the endoporus of interior wear-resistant sleeve and the annular outer wall of outer wear-resistant sleeve are cooperatively interact coniform, after described inside and outside wear-resistant sleeve interference fit, are cylindric; On described hub body, corresponding raceway position has oil hole, and oil nozzle is installed in oil hole.
Oil nozzle includes the oil nozzle body, in the oil nozzle body, has stepped hole, and the upper oral part fixed cover of stepped hole is equipped with oiling tube, and the outer end plug-in mounting of described oiling tube enters in described oil hole; In described oil nozzle body, the stepped portions of stepped hole is provided with the guide pipe of cone shape, between guide pipe and oiling tube, is provided with spring, in described guide pipe, is provided with globoid, and the globoid upper end is against on spring.
During use, the muzzle of oil gun is inserted in the through hole of oil nozzle body, by globoid and guide pipe jack-up carry out oiling simultaneously, so, has increased the sectional area of oil-feed, accelerated oil-feed speed.
Advantage of the present invention:
The present invention, by increase the inside and outside wear-resistant sleeve of interference fit in hub body, has strengthened the resistance to abrasion of automotive hub, in addition, by the oil nozzle that uses this special construction, regularly in wheel hub, injects lubricating oil, high lubricating effect.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The structural representation that Fig. 2 is oil nozzle.
The specific embodiment
Referring to accompanying drawing.
A kind of wear-resistant automotive hub with oil nozzle, include hub body 1, one end of hub body 1 is provided with the flange 2 of one, the intermediate location of flange 2 and hub body 1 is provided with the raceway 3 coordinated with bearing inner ring, in hub body, fixed cover is equipped with inside and outside wear- resistant sleeve 4,5, the annular outer wall of the endoporus of interior wear-resistant sleeve 4 and outer wear-resistant sleeve 5 is cooperatively interact coniform, after described inside and outside wear- resistant sleeve 4,5 interference fit, is cylindric.On described hub body 1, corresponding raceway position has oil hole, and oil nozzle 6 is installed in oil hole.
