Technical field
The utility model relates to automobile gearbox system, particularly a kind of gear box oil seal structures.
Background technique
In transmission system especially automatic transmission case system, there is more oil duct to be integrated in gear box casing and other modules, these oil ducts help the hydraulic system of gearbox to realize hydraulic function, comprise gearshift, cooling and clutch operating etc., in order to realize above-mentioned functions, require that oil duct has good sealing.
Existing gearbox oil duct sealing means mainly comprises steel ball sealing mode and bolt seal mode, wherein steel ball sealing mode refers to and fills in oil duct by steel ball extruding, realize sealing by the interference fit of steel ball and oil duct, this sealing means sealing effect is poor, bolt seal mode refers to and screws in oil duct by with externally threaded bolt, realizes sealing by the screw-thread fit between bolt and oil duct, and this sealing means needs machining internal thread on oil duct, oil duct difficulty of processing is large, and cost is high.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of easy to use, good sealing effect, the gear box oil seal structures that cost is low.
For solving the problems of the technologies described above, the gear box oil seal structures that the utility model provides comprises plug main body and spiral head, the outer surface of described plug main body is corresponding with the inwall of oil duct, described plug main body is provided with extrusion aperture, described extrusion aperture is blind hole, and described extrusion aperture comprises cooperation section and gap section successively from opening end to closed end, the section of the cooperation screw-thread fit of described spiral head and described extrusion aperture, when described spiral head installation, end and the described gap section of described spiral head form an enclosed cavity.
Preferably, described plug main body coordinates with described gallery space.
Preferably, the outer surface of described plug main body is provided with hangnail.
Preferably, the intermediate section of inner wall smooth is also provided with between the cooperation section of described extrusion aperture and gap section.
Preferably, the internal diameter of described cooperation section diminishes gradually along the direction towards described gap section.
Preferably, the section of described gap section is isosceles triangle.
Preferably, described spiral head is provided with Yi Zilan away from one end of described gap section.
First plug main body is put into oil duct when the gear box oil seal structures that the utility model provides uses, again spiral head is screwed in the cooperation section of extrusion aperture of plug main body, make to fill in main body by spiral head and the screw-thread fit of the section of cooperation to expand, thus sealing oil duct, and the enclosed cavity that forms of the end of spiral head and gap section is conducive to being supplied to when hydraulic oil contacts with the closed end of extrusion aperture and fills in the larger amount of deformation of main body, to seal oil duct better.
Accompanying drawing explanation
Fig. 1 is the utility model gear box oil seal structures example structure schematic diagram.
Indicate as follows in figure:
Plug main body-1, extrusion aperture-10, coordinates section-101, gap section-102, intermediate section-103, hangnail-11, spiral head-2, Yi Zilan-21, oil duct-3.
Embodiment
For enabling above-mentioned purpose, the feature and advantage of model utility more become apparent, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
As shown in Figure 1, the gear box oil seal structures that the utility model provides, comprise plug main body 1 and spiral head 2, the outer surface of described plug main body 1 is corresponding with the inwall of oil duct 3, described plug main body 1 is provided with extrusion aperture 10, described extrusion aperture 10 is blind hole, and described extrusion aperture 10 comprises cooperation section 101 and gap section 102 successively from opening end to closed end, the section of cooperation 101 screw-thread fit of described spiral head 2 and described extrusion aperture 10, when described spiral head 2 installation, end and the described gap section 102 of described spiral head 2 form an enclosed cavity, the installation of above-mentioned spiral head 2 refers to that the outside thread of spiral head 2 coordinates completely with the internal thread of the section of cooperation 101.It should be apparent to those skilled in the art that, the material of above-mentioned plug main body 1 preferably can be the flexible materials such as rubber, to provide larger amount of deformation, can be Spielpassung or interference fit between above-mentioned plug main body 1 and oil duct 3, gap value or magnitude of interference are arranged according to the actual requirements.
First plug main body 1 is put into oil duct 3 when the gear box oil seal structures that the utility model provides uses, again spiral head 2 is screwed in the cooperation section 101 of the extrusion aperture 10 of plug main body 1, make to fill in main body 1 by spiral head 2 and the screw-thread fit of the section of cooperation 101 to expand, thus sealing oil duct 3, and the enclosed cavity that forms of the end of spiral head 2 and gap section 102 is conducive to being supplied to when hydraulic oil contacts with the closed end of extrusion aperture 10 and fills in the larger amount of deformation of main body 1, to seal oil duct 3 better.
In order to more easily plug main body 1 be put into oil duct 3, described plug main body 1 and described oil duct 3 Spielpassung.
In order to anti-detent plug main body 1 comes off in oil duct 3 better, the outer surface of described plug main body 1 is provided with hangnail 11.
In a preferred embodiment of the present utility model, the intermediate section 103 of inner wall smooth is also provided with between the cooperation section 101 of described extrusion aperture 10 and gap section 102, being provided with of intermediate section 103 is beneficial to the larger enclosed cavity of formation, thus be supplied to the larger amount of deformation of plug main body 1, and, when spiral head 2 is with after the section of cooperation 101 screw-thread fit, also can applies external force and spiral head 2 is pressed into intermediate section 103 by force, thus be fixed on more solid and reliable for spiral head 2 in plug main body 1.
Be fixed on by spiral head 2 in plug main body 1 in order to more solid and reliable, the internal diameter of described cooperation section 101 diminishes gradually along the direction towards described gap section 102.
In order to more convenient plug main body 1 is out of shape, the section of described gap section 102 is isosceles triangle.
In order to screw in extrusion aperture 10 by spiral head 2 more easily, described spiral head 2 is provided with a word hurdle 21 away from one end of described gap section 102.
Although the utility model is described in conjunction with above embodiment, but the utility model is not defined to above-described embodiment, and only by the restriction of claims, those of ordinary skill in the art can easily modify to it and change, but do not leave essential idea of the present utility model and scope.
