Abstract
The utility model discloses a maintenance-free car hub which comprises a hub body. The hub body sleeves an axle tube. A hub bearing cavity is formed between the hub body and the axle tube. The maintenance-free car hub is characterized in that an integral bearing unit is disposed in the hub bearing cavity, the bearing unit comprises two bearings, lubricating grease and an oil seal, the lubricating grease is disposed in the bearings and sealed by the oil seal, one end of the bearing unit is provided with a locking nut for locking the bearings, the locking nut is matched with threads on the axle tube, and the hub bearing cavity is a straight-through cavity. The maintenance-free car hub has the advantages that the integral bearing unit is used, so that the maintenance cost of the hub is lowered greatly as compared with that of common hubs, and the low-cost and maintenance-free purpose is achieved.
Description
Technical field
The utility model relates to a kind of improvement invention of automotive hub, is specifically related to the improvement invention of the non-maintaining wheel hub of a kind of automobile.
Background technology
Between the two bearings of automotive hub, need the play that keeps best, the service life of guarantee bearing and the maintenance period of wheel hub.When installing on vehicle, traditional automotive hub assembles and adjusts play by installation personnel, easily produce error, and that play between bearing is crossed friction-tight is large, serious wear, the play between bearing is excessively loose, and bearing there will be and rocks when work, also can cause damage, thereby the service life of existing bearing is shorter, and the maintenance period of wheel hub is shorter, and use cost is very high.The bearing of wheel hub need to add lubricant when assembling simultaneously, also needs in use to add lubricant and is safeguarded, quite trouble.And the centre in hub bearing chamber has ledge structure, make wheel hub finish size tolerance and form and position tolerance be difficult to guarantee, reduced the assembly precision of wheel hub and bearing.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provide the setting of a kind of bearing unit integral type, assembling simple, without regulating play spacing and adding the non-maintaining wheel hub of automobile of lubricant.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme to realize: this kind of non-maintaining wheel hub of automobile, include hub body, described hub body is set in outside central siphon, between described hub body and central siphon, form hub bearing chamber, it is characterized in that: described hub bearing chamber is the setting of through type cavity, in described hub bearing chamber, be provided with the bearing unit that integral type arranges, described bearing unit comprises two bearings, grease and oil sealing, described grease is arranged in bearing by described oil sealing sealing, described bearing unit one end is provided with the jam nut of locking bearing, screw thread on described jam nut and central siphon matches.
The beneficial effects of the utility model are the non-maintaining wheel hubs of automobile after improving, hub bearing adopts integral metal, bearing clearance sets when bearing dispatches from the factory, during wheel hub assembling, do not need to adjust bearing clearance, directly bearing unit is pressed into wheel hub, reduced assembling and adjusted the impact of play error on bearing life, greatly improve the service life of bearing; Bearing includes special grease, does not need to add lubricant during assembling, in use also does not need to add lubricant, does not also need to safeguard; Because bearing adopts integral metal, hub bearing chamber is to have adopted straight-through structure, and there is ledge structure common wheel hub bearing bore centre, therefore wheel hub finish size tolerance is compared common wheel hub and is more easily guaranteed with form and position tolerance, improve the assembly precision of wheel hub and bearing, increased the service life of bearing.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Accompanying drawing has represented structure of the present utility model, further illustrates by reference to the accompanying drawings its details below again.The non-maintaining wheel hub of this automobile, include hub body 1, described hub body 1 is set in outside central siphon 2, and be connected with brake disc 6, between described hub body 1 and central siphon 2, form hub bearing chamber 3, in described hub bearing chamber 3, be provided with the bearing unit 4 that integral type arranges, described bearing unit 4 comprises two bearings, grease and oil sealing, play between described two bearings has been optimum efficiency Default Value, described grease is arranged in bearing and lives two-port by described oil sealing sealing, described bearing unit 4 one end are provided with the jam nut 5 of locking bearing, described jam nut 5 matches with the screw thread on central siphon 2, described hub bearing chamber 3 is the setting of through type cavity, in cavity without structures such as steps, and in common wheel hub bearing bore, be provided with step, so wheel hub finish size tolerance is compared common wheel hub and is more easily guaranteed with form and position tolerance.
Very convenient during the utility model assembling, because bearing unit is integral type setting, play between two bearings sets when bearing dispatches from the factory, during wheel hub assembling, do not need to adjust bearing clearance, can directly bearing unit be pressed into wheel hub, locking jam nut, has reduced assembling and has adjusted the impact of play error on bearing life, and greatly improve the service life of bearing; Bearing includes special grease, does not need to add lubricant during assembling, in use also does not need to add lubricant, does not also need to safeguard.
