Description
Technical field
The utility model belongs to steering axle of automobile technical field, and in particular to a kind of novel front axle wheel hub end housing structure.
Background technique
In existing steeraxle, wheel hub end housing mostly uses drill form to connect with wheel hub, pacifies between wheel hub end housing and wheel hub
Gasket is filled, packing grease is used for, such sealing structure performance is poor, and lubricating grease leaks frequent occurrence；It is general to use four
Above bolt connection is more using part, and assembly process is more, reduces assembly efficiency and reliability；Wheel hub need to process spiral shell
Pit, and the boss of arrangement threaded hole is increased, processing cost is increased, the weight of wheel hub is increased.
Summary of the invention
The utility model is that wheel hub end housing poor sealing performance, wheel hub end housing assembly efficiency are low in the existing steeraxle of solution, take turns
The problem that hub processing cost is high and weight is big, provides a kind of novel front axle wheel hub end housing structure.
The utility model adopts the following technical scheme that realization:
A kind of novel front axle wheel hub end housing structure, including wheel hub 1, wheel hub end housing 2 and assembly pressing element 5, wherein wheel hub end housing 2
Outer 7 interference of the diameter of axle of rubber face be connected on the outer bearing mounting hole 6 of wheel hub 1, and the first annular end face 3 of wheel hub end housing 2 with
Second annular end face 4 of wheel hub 1 is aligned, and in the ring section position adhesive seal rubber of connection, for wheel hub end housing 2 and wheel
Sealing between hub 1, assemble pressing element 5 on wheel hub 14 axial limiting of the second annular end face with it is first annular on wheel hub end housing 2
End face 3 is cooperatively connected.
Convex rotation body structure is used among the wheel hub end housing 2.
Outer bearing mounting hole 6 on the wheel hub 1 simultaneously for installing wheel hub outer bearing 8, will installation wheel hub outer bearing 8 with
The hole of wheel hub end housing 2 is unified, and processing technology is simplified.
Compared with prior art the beneficial effects of the utility model are:
The fit form that wheel hub end housing is pressed using rubber veneer sealing structure and interference in the utility model, while will peace
The hole Uniting for filling wheel hub outer bearing and wheel hub end housing is outer bearing mounting hole, simplify processing technology, improve sealing can
By property, promote assembly efficiency；Wheel hub uses circle hole shape fitting surface and annular end face, reduces the weight of wheel hub；This structure can adopt
It is dismantled with magnetic tool, prevents from arbitrarily dismounting.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the wheel hub end housing structural schematic diagram of the utility model.
Fig. 3 is the wheel hub end housing side view of the utility model.
Fig. 4 is the wheel hub structure schematic diagram of the utility model.
Fig. 5 is the wheel hub side view of the utility model.
Wherein: 1 wheel hub, 2 wheel hub end housings, 3 first annular end faces, 4 second annular end faces, 5 assembly pressing elements, 6 outer bearings peace
Fill hole, the outer diameter of axle of 7 rubber faces, 8 wheel hub outer bearings.
Specific embodiment
The present invention is further elaborated in conjunction with attached drawing.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, a kind of novel front axle wheel hub end housing structure, including wheel hub 1, hub end
Lid 2 and assembly pressing element 5, wherein outer 7 interference of the diameter of axle of the rubber face of wheel hub end housing 2 are connected on the outer bearing mounting hole 6 of wheel hub 1,
And the first annular end face 3 of wheel hub end housing 2 is aligned with the second annular end face 4 of wheel hub 1, and viscous in the ring section position of connection
Seal rubber is closed, for the sealing between wheel hub end housing 2 and wheel hub 1, it is axial with the second annular end face 4 on wheel hub 1 to assemble pressing element 5
Limit is cooperatively connected with the first annular end face 3 on wheel hub end housing 2.
As shown in Fig. 2, using convex rotation body structure, the protrusion for envelope knuckle among the wheel hub end housing 2
Structure, and 2 outer of wheel hub end housing is equipped with first annular end face 3, press fitting plane when for assembling；Wheel hub end housing 2 is adopted when dismantling
It is dismantled with magnetic tool, prevents from arbitrarily dismounting.
As shown in Figure 1, the outer bearing mounting hole 6 on the wheel hub 1 takes turns installation simultaneously for installing wheel hub outer bearing 8
The hole of hub outer bearing 8 and wheel hub end housing 2 is unified, and processing technology is simplified.
