Description
Technical field
The utility model belongs to vehicle bridge wheel frontier defense dirt technical field, and in particular to a kind of vehicle bridge wheel side dust-proof sealing structure.
Background technology
The working environment of wet braking vehicle is more severe so that vehicle bridge wheel side communicates with extraneous air and invaded by the grains of sand
Erosion, is equipped with oil sealing between wheel hub and braking inner tooth shell, oil sealing by being susceptible to damage under the abrasion of the grains of sand, causes oil sealing close for a long time
Envelope failure, leads to vehicle bridge oil leakage fault, reduces the service life of vehicle bridge.
Invention content
Place in order to overcome the above-mentioned deficiencies of the prior art, the utility model provide a kind of vehicle bridge wheel side dust seal knot
Structure.
The utility model is achieved by the following technical solution：A kind of vehicle bridge wheel side dust-proof sealing structure, including wheel hub
With the braking inner tooth shell being sleeved on the outside of wheel hub, wheel hub is assemblied in by bearing in support shaft, is covered between wheel hub and braking inner tooth shell
Equipped with box-type oil seal, several appearance dirt chambers are formed after wheel hub and braking inner tooth shell assembly, hold axial connection successively between dirt chamber, the first order
Hold dirt chamber with exterior space to be connected, afterbody holds dirt chamber and leads to box-type oil seal.
Further, two appearance dirt chambers are formed after the wheel hub and braking inner tooth shell assembly.
Further, the first order holds the gap δ 2 being connected between dirt chamber holds dirt chamber with afterbody and is less than first
Grade holds the gap δ 1 that dirt chamber is connected with exterior space.
Further, the bearing is taper roll bearing.
The utility model is by changing wheel hub and braking the structure of inner tooth shell so that wheel hub and braking inner tooth shell are being assembled
Several appearance dirt chambers are formed in inside after, the dust of intrusion is collected by holding dirt chamber.Shape after wheel hub and braking inner tooth shell assembly
At the axial slits communicated with exterior space and the first order hold dirt chamber and communicate；And dust can be accumulated in appearance under gravity
The near-earth side of dirt chamber, so that dust can be then exhausted from along axial slits；Upper level holds the appearance dirt that dirt chamber leads to next stage
The gap of chamber is then located at the centre position that upper level holds dirt chamber side wall so that dust is not easily accessible next stage and holds dirt chamber, further
Improve dust-proof effect.
The utility model has the beneficial effects that：The utility model is by changing wheel hub and braking the structure of inner tooth shell in wheel hub
Several appearance dirt chambers are formed to collect dust with braking inner tooth shell, are prevented dust from directly invading oil sealing, have been reached the mesh of protection oil sealing
's.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
In figure, 1, braking inner tooth shell, 2, box-type oil seal, 3, wheel hub, 4, bearing, 5, support shaft.
Specific implementation mode
The utility model is further illustrated below according to drawings and examples.
As shown in Figure 1, a kind of vehicle bridge wheel side dust-proof sealing structure, including wheel hub 3 and it is sleeved in the braking in 3 outside of wheel hub
Tooth shell 1, wheel hub 3 are assemblied in by bearing 4 in support shaft 5, and the bearing 4 is using taper roll bearing, wheel hub 3 and system
Be set with box-type oil seal 2 between dynamic inner tooth shell 1, wheel hub 3 and braking inner tooth shell 1 form several appearances dirt chambers after assembling, between appearance dirt chamber according to
Secondary axial connection, the first order hold dirt chamber and are connected with exterior space, and afterbody holds dirt chamber and leads to box-type oil seal 2.Such as Fig. 1 institutes
Show, in the present embodiment, forms two appearance dirt chambers after wheel hub 3 and the braking assembly of inner tooth shell 1, be connected with vehicle bridge exterior space
The first order, which holds dirt chamber C1 and holds the second level that dirt chamber C1 is connected with the first order, holds dirt chamber C2, and the second level holds dirt chamber C2 as last
Level-one is held dirt chamber and is communicated with box-type oil seal 2.It is wheel hub 3 and braking internal tooth that the first order, which holds dirt chamber C1 and leads to the gap δ 1 of exterior space,
The size of self-assembling formation after shell 1 assembles, gap δ 1 depends on wheel hub 3 and brakes the design size of inner tooth shell 1.Across gap δ 1
Dust initially enter and hold dirt chamber C1, collect and holding in dirt chamber C1, under gravity, dust, which will build up, holds dirt chamber C1's
Near-earth side holds the loop configuration of dirt chamber C1 near subaerial side；And the near-earth side axle of gap δ 1 is to appearance dirt chamber C1's
Near-earth side is connected so that being located at the dust of appearance dirt chamber C1 near-earths side can be discharged along gap δ 1.On the other hand hold with the second level
The gap δ 2 that dirt chamber C2 is connected then is located at the side wall for holding dirt chamber C1 by intermediate position so that is accumulated in and holds dirt chamber C1 near-earths side
Dust be not easily accessible gap δ 2 and then reach the second level and hold dirt chamber C2.The design of wheel hub 3 and braking inner tooth shell 1 at gap δ 2
Size is less than wheel hub 3 and brakes design size of the inner tooth shell 1 at gap δ 1, i.e. gap δ 2 is less than gap δ 1.The second level holds
The dust of dirt chamber C2 just influences whether box-type oil seal 2 when running up to certain, and box-type oil seal 2 comes with dust-proof and sealing in itself
Dual function.
The utility model is by changing wheel hub and braking the structure of inner tooth shell so that wheel hub and braking inner tooth shell are being assembled
Several appearance dirt chambers are formed in inside after, the dust of intrusion is collected by holding dirt chamber.Shape after wheel hub and braking inner tooth shell assembly
At the axial slits communicated with exterior space and the first order hold dirt chamber and communicate；And dust can be accumulated in appearance under gravity
The near-earth side of dirt chamber, so that dust can be then exhausted from along axial slits；Upper level holds the appearance dirt that dirt chamber leads to next stage
The gap of chamber is then located at the centre position that upper level holds dirt chamber side wall so that dust is not easily accessible next stage and holds dirt chamber, further
Improve dust-proof effect.
