The inner oil seal comprises an inner oil seal framework and an inner oil seal sealing lip. The integrated hub oil seal assembly further comprises an outer framework and an oil seal base. The outer framework is in interference fit with the inner wall of a hub shell and located on the outer side of the annular portion of the inner oil seal, the inner oil seal is fixed to the oil seal base, the inner oil seal sealing lip is located on the outer side of the annular portion of the inner oil seal framework and in interference fit with the outer framework, the outer side of the inner oil seal framework is connected with the inner oil seal sealing lip, the inner surface of the inner oil seal framework is in interference fit with the oil seal base, and an O-shaped ring is arranged on the inner surface inclined plane, matched with a half axle, of the oil seal base. The integrated hub oil seal assembly is simple in structure, convenient to assemble and good in sealing effect.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of integral type hub oil seal assembly.
Background technique
At present, the Sealing between existing wheel hub and semiaxis adopts oil sealing as shown in Figure 1, and this oil sealing is single oil sealing of existing ordinary construction, and this kind of oil seal structure is simple.But due to wheel hub and semi-axis structure complexity, by single oil sealing as shown in Figure 1 during for wheel hub and half shaft sealing, the assembling difficulty, rate of fault is high, easy oil leakage.
The model utility content
The purpose of this utility model is to have proposed a kind of integral type hub oil seal assembly, and it is simple in structure, easy to assembly, good sealing effect.
The utility model is to adopt following technological scheme to realize: the integral type hub oil seal assembly, comprise inner oil seal, inner oil seal comprises inner oil seal skeleton and inner oil seal seal lip, wherein, described oil seal assembly also comprises outer skeleton and the oil sealing base that is interference fit with the hub shell inwall, the dermoskeleton chord position is in the annular outboard of inner oil seal, inner oil seal is fixed on oil sealing base, inner oil seal seal lip is positioned at the annular outboard of inner oil seal skeleton, be interference fit between inner oil seal seal lip and outer skeleton, the outside of inner oil seal skeleton is connected with the inner oil seal sealing lip, be interference fit between the internal surface of inner oil seal skeleton and oil sealing base, the oil sealing base internal surface inclined-plane coordinated with semiaxis is provided with O type circle.
In the utility model, the internal surface of described inner oil seal skeleton is provided with annular corrugated rubber.
The outer surface of described oil sealing base is provided with back-up ring, can prevent that this oil seal assembly from dropping out in hub shell.
The beneficial effects of the utility model are: this integral type hub oil seal assembly first is mounted to one, then be assembled on wheel hub, so the cooperation between each parts of oil seal assembly is better, is conducive to protect the oil sealing of oil sealing, has improved the sealing effect of oil sealing; In addition, be convenient to the assembling of oil sealing, reduced assembly process, improved the efficiency of assembling of oil sealing.
The accompanying drawing explanation
Fig. 1 is the half sectional view of existing oil sealing;
Fig. 2 is the sectional view of integral type hub oil seal assembly in the utility model;
Fig. 3 is the half sectional view of inner oil seal in the utility model;
Fig. 4 is the assembly structure schematic diagram of integral type hub oil seal assembly.
In figure: 1 outer skeleton; 2 inner oil seals; 21 inner oil seal seal lips; 22 inner oil seal skeletons; 23 springs; 3 oil sealing bases; 40 type circles; 5 semiaxis; 6 back-up rings; 7 hub shell.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 2; this integral type hub oil seal assembly comprises outer skeleton 1, inner oil seal 2 and oil sealing base 3; outer skeleton 1 is positioned at the annular outboard of inner oil seal 2; by outer skeleton 1 is set, can reduce the lip size of inner oil seal, simultaneously when inner oil seal is installed; the inner oil seal lip can directly not contact with the hub shell inwall; avoid lip and seat hole wall that long installation stroke is arranged, protected the inner oil seal lip, reduced the probability that lip is scratched.Be interference fit between outer skeleton 1 and hub shell inwall.
The part hole wall of oil sealing base 3 center holes is inclined-plane.After this oil seal assembly has assembled, oil sealing base 3 is an inclined-plane with the contact position of semiaxis 5, the frictional force that whole oil sealing base 3 produces by this inclined-plane to keep relative static with axle, because surface of contact is longer, can prevent that medium from oozing out from this inclined-plane, strengthened sealing effect by O type circle 4 is set.As shown in the figure, the inclined-plane of oil sealing base 3 hole walls is provided with annular groove, and O type circle 4 is arranged in annular groove.
The outer surface of oil sealing base 3 is provided with back-up ring 6, and back-up ring 6, between hub shell inwall and oil seal assembly, can prevent that this oil seal assembly from dropping out in hub shell.
During this oil sealing assembling, at first outer skeleton 1 is assembled on the inner oil seal sealing lip lip be mated, O type circle 4 is set on the internal surface inclined-plane of oil sealing base 3, oil sealing is assembled into to one; Then, whole oil sealing is installed on hub shell 7 together, and back-up ring 6 is arranged between oil sealing base 3 and hub shell 7, finally by semiaxis 5 to the endoporus of oil sealing base 3.This integral type hub oil seal assembly is assembled to hub shell 7 when interior; at first this oil seal assembly is installed and is an integral body; therefore the cooperation between each parts of this oil seal assembly is better; be conducive to protect oil sealing; be convenient to the assembling of oil sealing; reduce assembly process, improved the efficiency of assembling of oil sealing, good sealing effect.
