Abstract
The utility model discloses a novel hub oil lubrication structure, which comprises a hub body with a bolt connection hole, a hub axle tube and bearings, wherein the bearings are arranged on the inner side and the outer side of the hub body. The inner sides of the two bearings are provided with oil baffle discs connected with the hub body, the outer sides of the two bearings are provided with oil seals, each oil baffle disc and the corresponding oil seal form a cavity which is used for sealing bearings, an oil access passage which is used for communication of the exterior of the hub body with a hub axle tube mounting hole is arranged in the bolt connection hole, and the hub axle tube mounting hole is communicated with the cavities. An existing bolt hole structure is ingeniously used for arrangement of the oil access passage, usage of parts such as oil feeding (discharging) bolts can be reduced, and part number can be decreased. By means of the oil baffle discs, lubricating oil which is thrown out at a high speed can change movement direction through retaining of the oil baffle discs to lead back injection, balls on the upper sides of the bearings can be lubricated completely in high-speed rotation of the bearings, lubrication dead spaces, dry grinding of the balls and the like due to defective lubrication can be avoided, and the service lives of the bearings can be effectively prolonged.
Description
Technical field
The utility model relates to automotive field, specifically a kind of novel hub oil lubrication structure.
Background technology
Automotive wheel is used for tight pulley tire inner edge, supporting tire and bears carload jointly with tire, and wheel supports through wheel hub and hub bearing, so the wheel hub performance plays an important role to traffic safety.Hub bearing is one of parts of most critical in the wheel hub, and in the driving, hub bearing is worked in high speed, high-mechanic, hot environment, and therefore good lubricating method played an important role to the life-span of bearing.At present hub bearing mostly adopts grease lubrication, but the grease lubrication wheel hub is relatively poor relatively to the lubricated and protective capability of bearing owing to receive that lubricant medium self flowing power is poor, heat-sinking capability is low, be prone to melt Effect on Performance such as inefficacys at a certain temperature.
Summary of the invention
Deficiency to the prior art existence; The utility model technical matters to be solved is; Provide a kind of simple in structure, with low cost; Through the bearing lubrication space of relative closure is set, improve the lubricated environment of bearing effectively, the novel hub oil lubrication structure in the service life of significant prolongation bearing.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of novel hub oil lubrication structure; Comprise hub body, hub axle tube with bolt connecting hole and the bearing of being located at these inside and outside both sides of hub body; Said two bearings inboard is provided with and hub body bonded assembly oil baffle disc; Be provided with the oil sealing that is used for the cavity of sealed bearings with said oil baffle disc formation one in the two bearings outside, in bolt connecting hole, offer the turnover oil passage that is communicated with hub body outside and hub axle tube mounting hole, said hub axle tube mounting hole is communicated with cavity.
The advantage of a kind of novel hub oil lubrication of the utility model structure is: a tapped through hole is set, is used to add (putting) lubricating oil, this structure can reduce to add the use of parts such as (putting) plug screw, reduces amount of parts.The ingenious structure of utilizing has the bolt hole structure, and the oily passage of turnover is set, and can reduce the use that adds parts such as (putting) whelk plug, reduces amount of parts; Wheel hub outer bearing place, arranged outside one oil sealing, the inboard is provided with an oil baffle disc; The hub inner bearing place adopts similar configuration, and this structure makes hub bearing form the lubricated environment of a relative leak free, and lubricating oil flows into through the gap between oil baffle disc and the hub axle tube; Lubricating bearings downside ball, along with the running of bearing, lubricating oil drives through ball; Make whole bearing all be in the oil lubrication state, with oil baffle disc and oil sealed unitized construction, for hub bearing provides an oil lubrication environment that relative closure is stable; Make bearing when high-speed operation, all balls all can obtain sufficient lubrication.And oil baffle disc adopts sheet steel to be stamped to form, and simple in structure, cost is lower, and this wheel hub oil lubrication structure is improved the lubricated environment of bearing effectively through the bearing lubrication space of relative closure is set, the service life of ability significant prolongation bearing.
Description of drawings
Fig. 1 is the full sectional view of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details;
As shown in Figure 1; A kind of novel hub oil lubrication structure; Comprise hub body 2, hub axle tube 3 with bolt connecting hole 1 and the bearing 4 of being located at the inside and outside both sides of this hub body 2; Two bearings 4 inboards are provided with and hub body 2 bonded assembly oil baffle discs 5; Be provided with the oil sealing 7 that is used for the cavity 6 of sealed bearings 4 with oil baffle disc 5 formation one in two bearings 4 outsides, in bolt connecting hole 1, offer the turnover oil passage 8 that is communicated with hub body 2 outsides and hub axle tube mounting hole 31, hub axle tube mounting hole 31 is communicated with cavity 6.The utility model adopts the oil lubrication structure, and adopts punching press oil baffle disc 5 and oil sealing 7 unitized constructions, and actv. has improved the lubricant effect of hub bearing 4, in the service life of ability significant prolongation bearing 4, improves travel safety.When bearing 4 high-speed operations; Bearing 4 upside balls get rid of oil at a high speed, be provided with oil baffle disc 5 can make the lubricating oil that throws away at a high speed through oil baffle disc 5 stop the change sense of motion, produces back and sprays phenomenon; When guaranteeing bearing 4 high-speed operations; Bearing 4 upside balls are fully lubricated, avoid occurring lubricated dead angle and ball because of the phenomenons such as dry grinding that insufficient lubrication produces, and prolonged the service life of bearing 4 effectively.
Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the utility model, the variation of making, remodeling, interpolation or replacement all should belong to the protection domain of the utility model.
