Abstract
The utility model relates to a sealing member for sealing, in particular to an oil seal of an axle wheel hub. The oil seal consists of an inner oil seal framework and an outer oil seal framework, wherein the inner oil seal framework is provided with an inner rubber body; the outer oil seal framework is provided with an outer rubber body; an assembling reinforcement is arranged on the outer side of the inner rubber body; a rubber bulge is arranged at the bottom of the outer rubber body away from one side of the inner oil seal framework; and a concave-convex positioning structure is arranged at one end relatively close to the inner oil seal framework. In the oil seal of the axle wheel hub, the assembling reinforcement is arranged on the inner rubber body positioned on the inner oil seal framework, the assembly and disassembly of the bearing is facilitated; and the rubber bulge and the concave-convex positioning structure are arranged on the outer rubber body, so that the sealing property and the carrying capacity of the oil seal are enhanced. In addition, with the adoption of the oil seal, the dustproof intensity is increased, the resisting capability to foreign matters of larger particles is improved, good sealing property can be kept when the oil seal is used for a long time, and the service life of the oil seal is prolonged.
Description
Technical field
The utility model relates to Sealing, relates in particular to a kind of vehicle bridge hub oil seal.
Background technique
The vehicle bridge hub oil seal is the Sealing that is used to seal the inner lubricant oil of wheel hub; It mainly plays the effect of two aspects: 1; Prevent the lubricated leakage that has through the oil sealing lip on the oil sealing, make bearing have good lubricated adjusting, prevent the lubricant pollution brake drum and cause the brake ability to weaken; 2, stop foreign to get into the damage that wheel hub causes bearing through the dust excluder lips that is arranged on the outer oil seal skeleton.Traditional hub oil seal thermal diffusivity is relatively poor, and renitent performance is less, under dismounting can not be with the bearing inner race band during wheel hub, and causes oil-sealing mouth or dustproof lip to be made oil seal failure by scratch; In assembly process, crush easily simultaneously.In order to address the above problem, the utility model provides a kind of vehicle bridge hub oil seal, and it helps the assembling of running in bearings through the assembling muscle on the rubber body in being arranged on, and through being arranged on the concavo-convex position structure on the outer rubber body, has strengthened bearing capacity simultaneously.
Summary of the invention
The purpose of the utility model is, provides a kind of and helps the running in bearings assembling, and strengthened the vehicle bridge hub oil seal of bearing capacity.
In order to achieve the above object, the utility model provides a kind of vehicle bridge hub oil seal, and it is made up of with the outer oil seal skeleton that is provided with the outer rubber body the inner oil seal skeleton of rubber body in being provided with, and the arranged outside of described interior rubber body has the assembling muscle; In the bottom of described outer rubber body, be provided with rubber projections away from a side of inner oil seal skeleton, be provided with concavo-convex position structure from the nearer end of inner oil seal skeleton.
Described assembling muscle is 3～5.
The beneficial effect of the utility model: the interior rubber body that is arranged on the inner oil seal skeleton in this vehicle bridge hub oil seal is provided with the assembling muscle; Help the assembling and the dismounting of bearing; Rubber projections that is provided with on the rubber body outside and concavo-convex position structure have strengthened the sealing and the bearing capacity of oil sealing.This oil sealing has strengthened dustproof intensity, has improved the defensive ability/resistance ability to the bigger foreign matter of particle, and when long-time the use, still can keep good sealing property, has prolonged the working life of oil sealing.
Description of drawings
Fig. 1 is the structural representation of the described vehicle bridge hub oil seal of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the described vehicle bridge hub oil seal of the utility model is elaborated.
Fig. 1 is the structural representation of the described vehicle bridge hub oil seal of the utility model.This vehicle bridge hub oil seal comprises outer oil seal skeleton 1 and inner oil seal skeleton 2; Oil tight skeleton 1 is provided with outer rubber body 3 outside; Inner oil seal skeleton 2 is provided with interior rubber body 4, and the arranged outside of interior rubber body 4 has three assembling muscle 5, and this assembling muscle 5 can be to contacting with positioning boss 6; Under can be in the dismounting wheel hub, prevent that oil seal lip is by the inner ring scratch with the bearing inner race band.
The side away from inner oil seal skeleton 2 is provided with rubber bumps 10 on the rubber body 3 outside, is provided with concavo-convex position structure 11 in a side that approaches inner oil seal skeleton 2.Wherein, rubber bumps 10 can be pressed into outer oil seal skeleton 1 and inner oil seal skeleton 2 specified position of wheel hub simultaneously, is convenient to the assembling of oil sealing.Concavo-convex position structure 11 has strengthened bearing capacity between rubber bumps 10 and dust excluder lips 8.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
