Description
Technical field
The present invention relates to transmission shaft oil-sealing structure, and in particular to a kind of dust cover and drive axle support oil enveloping structure.
Background technology
In existing heavy duty transmission axle, it is provided with intermediate support assembly and dust cover, and intermediate support assembly plays support transmission
The effect of axle and buffering, intermediate support assembly forms a whole together with dust cover, blocks extraneous muddy water, dust and enters bearing
In, prevent bearing because of earlier period damages such as extraneous muddy water, dusts.But the structure ratio that existing intermediate support assembly is constituted with dust cover
Relatively simple, straight up and down, without intermediate interlayer, muddy water directly can directly reach branch to cavity along interlayer between dust cover and support
At frame oil seal lip.Because bracket oil seal lip is cylindrical close to vertical cooperation with preceding splined shaft bearing guard, outside muddy water is stopped
Effect is not strong, and existing oil enveloping structure oil seal lip does not have wear-compensating effect in addition, therefore oil sealing slightly weares and teares, muddy water is just easier to
Enter rack bore along laterally red lines track.After time length, water will be filled with cavity herein, finally enter in bearing
Portion, causes bearing failure.

The homonymy of body bends and stretched out, the angle between the axis of the flanging and the dust cover main body be more than the in-flanges with
Angle between the axis of the dust cover main body.
A kind of drive axle support oil enveloping structure, including intermediate support assembly and the dust cover described in claim 1, institute
State intermediate support assembly and be provided with bracket oil seal, the dust cover is equipped with one by one with the bracket oil seal, the flanging
And the in-flanges stretches out towards with the bracket oil seal direction that the dust cover coordinates.
It is preferred that, the bracket oil seal includes oil sealing main body, and the oil sealing main body is provided with outer lip, middle part lip and interior
Portion's lip, the outer lip is stretched between the flanging and the in-flanges, and the in-flanges stretches into the outer lip and institute
In the middle part of stating between lip.
It is preferred that, the outer lip and the cylindrical interference fit of power transmission shaft.
It is preferred that, the end of the remote dust cover main body of the in-flanges is contacted with the surface of the oil sealing main body.
It is preferred that, the end face of the middle part lip is contacted with the surface of the in-flanges.
Beneficial effects of the present invention：
The present invention is scientific and reasonable for structure, and the flanging and in-flanges of dust cover can effectively coordinate realization more preferable with bracket oil seal
Sealing property, prevent dust, muddy water etc. enter drive axle support inside, while when coordinating with bracket oil seal, fan can be formed
Palace formula sealing structure, it is to avoid muddy water is reached on the outside of oil seal lip.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Referring to Fig. 1, the present embodiment provides a kind of dust cover 10：Including dust cover main body 13, dust cover main body 13 is ring
Shape, the cross section of dust cover main body 13 is L-shaped, and two free ends of dust cover main body 13 are respectively arranged with flanging 11 and interior
Flange 12, flanging 11 and in-flanges 12 bend and stretched out towards the homonymy of dust cover main body 13, flanging 11 and dust cover master
Angle between the axis of body 13 is more than the angle between in-flanges 12 and the axis of dust cover main body 13.
Fig. 2 and Fig. 3 are referred to, the present embodiment also provides a kind of drive axle support oil enveloping structure, including intermediate support assembly
3 and foregoing dust cover 10, intermediate support assembly 3 is arranged on the bearing 1 of power transmission shaft, and the two ends of intermediate support assembly 3 are equal
Be provided with bracket oil seal 20, dust cover 10 is two, is equipped with one by one with two bracket oil seals 20 respectively, flanging 11 and
In-flanges 12 stretches out towards with the direction of bracket oil seal 20 that dust cover 10 coordinates.Flanging 11 and in-flanges 12 are used to seal branch
The gap formed between frame oil sealing 20 and dust cover main body 13.
It is preferred that, in the present embodiment, bracket oil seal 20 includes oil sealing main body, and oil sealing main body is provided with outer lip 21, middle part
Lip 22 and internal lip 23, it is deep that outer lip 21, middle part lip 22 and internal lip 23 are directed towards the direction of dust cover main body 13
Place.Wherein, outer lip 21 be big incline structure, and with the cylindrical interference fit of power transmission shaft.Main rise stops that outside muddy water enters
The effect of internal stent, while this big incline structure can be when bracket oil seal 20 has a small amount of abrasion, automatic holding axle is cylindrical
Effective magnitude of interference between guarantee bracket oil seal 20 and axle are cylindrical, it is ensured that oil seal lip and the preceding oil sealing of splined shaft 4 shelves long-term close
Coordinate.
Specifically, outer lip 21 is stretched between flanging 11 and in-flanges 12, in-flanges 12 stretches into outer lip 21 and middle part
Between lip 22.And the end of the remote dust cover main body 13 of in-flanges 12 is contacted with the surface of oil sealing main body.Middle part lip
22 end face is contacted with the surface of in-flanges 12.The anti-muddy water of multilayer labyrinth type is constituted so between dust cover 10 and bracket oil seal 20
Structure.Flanging 11, the outer lip 21 of in-flanges 12 and bracket oil seal 20, middle part lip 22 and the internal lip of dust cover 10
Space between 23 is divided into three parts, and each part plays a part of stopping that muddy water enters internal stent, so as to have
Stop muddy water, the dust of effect enter internal stent.
During use, muddy water is most of first to be blocked by the flanging 11 of dust cover 10, and only a small amount of muddy water can enter
Enter the space between dust cover 10 and bracket oil seal 20.Muddy water enters behind this space, can be kept off by the in-flanges 12 of dust cover 10
Firmly, flow to the inner space bottom of dust cover 10 along the inclined-plane of in-flanges 12, then because power transmission shaft rotating centrifugal effect and
Muddy water Action of Gravity Field itself, can throw away space between dust cover 10 and support, again along the inner side of flanging 11 of dust cover 10
Reach power transmission shaft exterior space.Only few part muddy water is once in a while between the in-flanges 12 and bracket oil seal 20 of dust cover 10
Space, and down blocked by middle part lip 22, as a same reason because the effect of power transmission shaft rotating centrifugal and muddy water gravity itself
Effect, can the space that be come back to along bracket oil seal 20 between the in-flanges 12 of dust cover 10 and flanging 11, then along dust cover
10 flanging 11 returns to the exterior space of bracket oil seal 20 and dust cover 10.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
