Abstract
The invention discloses a vehicle axle wheel hub system. The vehicle axle wheel hub system comprises a wheel hub, an outer bearing, an inner bearing and a framework seal ring, wherein the outer bearing and the inner bearing are installed in a wheel hub cavity; the wheel hub cavity is internally provided with a first oil retainer ring; the inner bearing is positioned between the first oil retainer ring and the framework seal ring; a cavity between the first oil retainer ring and the framework seal ring forms a grease collecting cavity for gathering lubricating grease of the inner bearing into the cavity; the wheel hub cavity is internally provided with a second oil retainer ring and the third retainer ring; the outer bearing is positioned between the second oil retainer ring and the third retainer ring; a cavity between the second retainer ring and the third retainer ring forms a grease collecting cavity for gathering lubricating grease of the outer bearing into the cavity. According to the invention, the lubricating grease is gathered to the parts of the inner bearing and the outer bearing, so that the using quantity of lubricating grease is reduced greatly, and the lubricating grease utilization ratio is high; lubricating grease can enter the bearings easily, and can be supplied well for the bearings, so that the lubricating grease utilization ratio is improved, and the service life of the bearings is prolonged.
Description
Technical field
The present invention relates to axle hub structure, relate in particular to the bearing lubrication structure in wheel hub.
Background technique
In existing axle hub system, particularly be applied in the hub system of semitrailer axle, bearing lubrication structure in wheel hub is reasonable not, and lubricating grease is dispersed in whole wheel hub cavity, can not concentrate on the position at bearing place, cannot be bearing supplemental lubrication fat well, reduce bearing life, and lubricating grease consumption is very large, the wheel hub cavity of every axle need inject 0.8～1.2kg lubricating grease conventionally, lubricating grease utilization ratio is low, causes waste.
Summary of the invention
The object of this invention is to provide a kind of axle hub system, to improve the utilization ratio of lubricating grease, and can extend the working life of bearing.
The present invention is achieved in that a kind of axle hub system, comprise wheel hub, be arranged on the outer bearing in wheel hub cavity, inner bearing and backbone sealing ring, the first oil deflector is installed in wheel hub cavity, inner bearing is between the first oil deflector and backbone sealing ring, cavity between the first oil deflector and backbone sealing ring forms concentrates collection chamber in the inner by the lubricating grease of inner bearing, the second oil deflector and the 3rd oil deflector are installed in wheel hub cavity, outer bearing is between the second oil deflector and the 3rd oil deflector, cavity between the second oil deflector and the 3rd oil deflector forms concentrates collection chamber in the inner by the lubricating grease of outer bearing.
As further improvement or preferred forms, the present invention can also adopt following attached technological scheme.
Described the first oil deflector, the second oil deflector are provided with the groove that holds lubricating grease.
Described the first oil deflector is clamped between the outer ring and the boss on wheel hub cavity inwall of inner bearing, and described the second oil deflector is clamped between the outer ring and the boss on wheel hub cavity inwall of outer bearing.
Described the 3rd oil deflector is installed with on the bearing lock nuts of axle shaft end.
Outer limited ring and interior limited ring are installed in wheel hub cavity, described outer bearing, inner bearing, backbone sealing ring, the first oil deflector, the second oil deflector and the 3rd oil deflector being installed with on bearing lock nuts concentrate between outer limited ring and interior limited ring jointly, and the internal diameter of outer limited ring is less than the external diameter of the 3rd oil deflector.
Advantage of the present invention is that lubricating grease concentrates on the position at inner bearing and outer bearing place, can greatly reduce lubricating grease use amount, lubricating grease utilization ratio is high, and lubricating grease is easy to enter in bearing, can be bearing supplemental lubrication fat well, improve lubricating grease utilization ratio, extend bearing working life.
Accompanying drawing explanation
Fig. 1 is general structure schematic diagram of the present invention.
Embodiment
Referring to Fig. 1, according to a kind of axle hub system of the present invention, comprise wheel hub 1, be arranged on outer bearing 2, inner bearing 3 and backbone sealing ring 4 in wheel hub cavity.The first oil deflector 5, the first oil deflectors 5 are installed in wheel hub cavity to be clamped between the outer ring 3a of inner bearing 3 and the boss 6 of wheel hub cavity inwall.Inner bearing 3 is between the first oil deflector 5 and backbone sealing ring 4.Cavity between the first oil deflector 5 and backbone sealing ring 4 forms concentrates collection chamber in the inner by the lubricating grease of inner bearing.The second oil deflector 7 and the 3rd oil deflector 8 are installed in wheel hub cavity.The second oil deflector 7 is clamped between the outer ring 2a of outer bearing 2 and the boss 9 of wheel hub cavity inwall.Outer bearing 2 is between the second oil deflector 7 and the 3rd oil deflector 8.Cavity between the second oil deflector 7 and the 3rd oil deflector 8 forms concentrates collection chamber in the inner by the lubricating grease of outer bearing.The first oil deflector 5 and the second oil deflector 7 respectively global formation have the groove 10 that holds lubricating grease, to lay in more lubricating grease.
The 3rd oil deflector 8 of the present embodiment and bearing lock nuts 11 global formations of axle shaft end, the nut of a flanged dish of formation, the 3rd oil deflector 8 is exactly the flange plate of this nut.The 3rd oil deflector 8 can also adopt together with welding manner is installed with bearing lock nuts 11.In addition, the 3rd oil deflector 8 can also be a packing ring or the similar part being independent of outside bearing lock nuts.Between bearing lock nuts 11 and the inner ring of outer bearing 2, accompany lock washer 14.
As preferred forms, the present embodiment is provided with outer limited ring 12 and interior limited ring 13 in wheel hub cavity, outer bearing 2, inner bearing 3, backbone sealing ring 4, the first oil deflector 5, the second oil deflector 7 and the 3rd oil deflector 8 being installed with on bearing lock nuts concentrate between outer limited ring 12 and interior limited ring 13 jointly, and the internal diameter of outer limited ring 12 is less than the external diameter of the 3rd oil deflector 8.Outer limited ring 12 and interior limited ring 13 can adopt jump ring, and jump ring is stuck in the groove of wheel hub cavity inwall.The advantage of this preferred forms is, in the time of dismounting bearing lock nuts 11, can be by being installed with limited ring 12 outside the 3rd oil deflector 8 top pressures on nut, by outer limited ring 12, drive wheel hub 1 together with interior limited ring 13 again, by outer bearing 2, the second oil deflector 7, the first oil deflector 5, inner bearing 3, backbone sealing ring 4 is pulled out and is unloaded from axletree together, dismounting is very convenient, and the outer bearing 2 unloading from axletree, the second oil deflector 7, the first oil deflector 5, numerous component such as inner bearing 3 and backbone sealing ring 4, still be integrated in wheel hub cavity, avoided bearing and lubricating grease by the extraneous grains of sand, the foreign substance pollution such as dust and steam, maintenance or maintenance qualities have been improved.
