Description
Technical field
This utility model relates to a kind of automobile hub bearing, especially relates to a kind of eco-friendly car hub-bearing unit.
Background technology
Bearing, as the vitals of each transmission portion of automobile, generally uses alloy manufacture, and the stability of automobile and safety etc. are had important function and meaning.Development especially with automobile industry, automotive performance improves constantly, quality and performance requirement to each parts also improve constantly, the most especially tackle various run up, the stability of high loaded process lower bearing, wearability, lubricity and safety etc. increasingly constitute the important subject of current automobile industry.Chinese patent discloses a kind of automobile bearing (Authorization Notice No.: CN 203431035 U), it includes outer ring, rolling element, retainer, inner ring and sealing lid, in wherein rolling element is uniformly arranged on retainer, outer ring, retainer, inner ring and sealing lid are installed the most successively, the both sides, outer face of outer ring are provided with fin, inner face both sides, outer ring are provided with aluminium alloy heat absorbing sheet, fin passes through with aluminium alloy heat absorbing sheet to be connected inside and outside heat-conducting block realization, on the inner surface of outer ring, lower end is provided with heat conduction bar, and the stem of heat conduction bar is all connected with heat-conducting block with afterbody；The end face sealing lid offers an oil groove；The connected mode sealing lid and outer ring is interference fits；Fin, aluminium alloy heat absorbing sheet and heat conduction bar are connected with outer ring by the way of welding.But this automobile bearing is more inaccurate to the location of steel ball, easily producing and beat, transmission efficiency is relatively low, and the sealing of whole bearing, lubrication are the most thorough.
Utility model content
This utility model is to provide a kind of eco-friendly car hub-bearing unit, its automobile bearing mainly solved existing for prior art is more inaccurate to the location of steel ball, easily producing and beat, transmission efficiency is relatively low, and the technical problem that the sealing of whole bearing, lubrication are the most thorough etc..
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals:
A kind of eco-friendly car hub-bearing unit of the present utility model, including a pair inner ring, the outside of described inner ring is provided with outer ring, and inside and outside circle is designed with raceway groove, is provided with steel ball in raceway groove, steel ball is spacing by retainer, being provided with black box between inner ring and outer ring, raceway groove the inner of inner ring is provided with spacing rubber ring, and the section of spacing rubber ring is swallow-tail form, it is embedded at the inclined-plane of channel-end tip, and the end of spacing rubber ring withstands on retainer.Spacing rubber ring is designed as swallow-tail form, and it can be stuck at the inclined-plane of channel-end tip, and with retainer as fulcrum, carries out spacing to steel ball.The outer surface of spacing rubber ring is the arc surface of laminating steel ball surface.
As preferably, described black box includes the metallic framework of the pair of L-shaped being connected on outer ring, and it is attached with sealing member, and sealing member is provided with three sealing lips.The structure of sealing member is relatively simple, and it has three sealing lips just can play dust-proof effect.
As preferably, one of them described inner ring offering oil duct, the outer end of oil duct is provided with horn mouth, and horn mouth offers the distributing damper that polylith becomes divergence form to be distributed.Horn mouth can inject oils and fats easily, but in order to prevent pressure of grease excessive, therefore arranges distributing damper, it is possible to reduce oil pressure, it is ensured that inner ring is properly functioning.
Therefore, this utility model utilizes spacing rubber ring steel ball can be carried out spacing work, such that it is able to very prevent steel ball from beating to limits, thus increase transmission efficiency, utilize and oil duct is set at inner ring, strengthen the lubrication to steel ball, and ensure that steel ball runs intensity, simple and reasonable for structure.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model；
Accompanying drawing 2 is a kind of structural representation of this utility model black box.
Parts, position and numbering in figure: inner ring 1, outer ring 2, raceway groove 3, steel ball 4, retainer 5, spacing rubber ring 6, metallic framework 7, sealing member 8, oil duct 9, horn mouth 10, distributing damper 11.
Detailed description of the invention
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment: a kind of eco-friendly car hub-bearing unit of this example, such as Fig. 1, including a pair inner ring 1, the outside of inner ring is provided with outer ring 2, raceway groove 3 it is designed with on inside and outside circle, being provided with steel ball 4 in raceway groove, steel ball is spacing by retainer 5, is provided with black box between inner ring and outer ring, raceway groove the inner of inner ring is provided with spacing rubber ring 6, the section of spacing rubber ring is swallow-tail form, and it is embedded at the inclined-plane of channel-end tip, and the end of spacing rubber ring withstands on retainer.Such as Fig. 2, black box includes the metallic framework 7 of the pair of L-shaped being connected on outer ring 2, it is attached with sealing member 8, and sealing member is provided with three sealing lips.Offering oil duct 9 on one of them inner ring, the outer end of oil duct is provided with horn mouth 10, and horn mouth offers the distributing damper 11 that polylith becomes divergence form to be distributed.
During use, this utility model is loaded front hub of vehicle.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and change or the modification made all are contained among the scope of the claims of the present utility model.
