Description
Technical field
The invention 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 car is more severe so that vehicle bridge wheel side communicates with extraneous air and invaded by the grains of sand
Erosion, is provided with oil sealing between wheel hub and braking inner tooth shell, oil sealing by easily being damaged under the abrasion of the grains of sand, causes oil sealing close for a long time
Envelope failure, causes vehicle bridge oil leakage fault, reduces the service life of vehicle bridge.
The content of the invention
Part in order to overcome the above-mentioned deficiencies of the prior art, the present invention provide a kind of vehicle bridge wheel side dust-proof sealing structure.
The present invention is achieved through the following technical solutions：A kind of vehicle bridge wheel side dust-proof sealing structure, including wheel hub and set
Braking inner tooth shell on the outside of wheel hub, wheel hub are assemblied in support shaft by bearing, are set between wheel hub and braking inner tooth shell
Box-type oil seal, wheel hub and braking inner tooth shell form some appearance dirt chambers after assembling, hold axially connection successively between dirt chamber, first order appearance dirt
Chamber is connected with exterior space, and afterbody holds dirt chamber and leads to box-type oil seal.
Further, two appearance dirt chambers are formed after described wheel hub and braking inner tooth shell assembling.
Further, the described first order holds the gap δ 2 being connected between dirt chamber holds dirt chamber with afterbody and is less than first
Level holds the gap δ 1 that dirt chamber is connected with exterior space.
Further, described bearing is taper roll bearing.
The present invention is by changing wheel hub and braking the structure of inner tooth shell so that wheel hub and braking inner tooth shell are after the completion of assembling
Some appearance dirt chambers are internally formed, the dust of intrusion is collected by holding dirt chamber.Formed after wheel hub and braking inner tooth shell assembling
The axial slits communicated with exterior space are held dirt chamber with the first order and communicated；And dust can be accumulated in hold dirt chamber under gravity
Near-earth side, and then dust is then exhausted from along axial slits；Upper level appearance dirt chamber leads to the appearance dirt chamber of next stage
Gap 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 improves
Dust-proof effect.
The beneficial effects of the invention are as follows：The present invention is by changing wheel hub and braking the structure of inner tooth shell in wheel hub and braking
Tooth hull shape collects dust into some appearance dirt chambers, prevents dust from directly invading oil sealing, has reached the purpose of protection oil sealing.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
In figure, 1, braking inner tooth shell, 2, box-type oil seal, 3, wheel hub, 4, bearing, 5, support shaft.
Embodiment
Below according to drawings and examples, the present invention is further described.
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 the outside of wheel hub 3
Tooth shell 1, wheel hub 3 are assemblied in support shaft 5 by bearing 4, and described bearing 4 is using taper roll bearing, wheel hub 3 and system
Box-type oil seal 2 is set between dynamic inner tooth shell 1, wheel hub 3 and braking inner tooth shell 1 form some appearance dirt chambers after assembling, hold between dirt chamber according to
Secondary axially connection, the first order are held 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, form two appearance dirt chambers after wheel hub 3 and the braking assembling of inner tooth shell 1, be connected with vehicle bridge exterior space
The first order holds dirt chamber C1 and holds dirt chamber C2 with the first order appearance dirt chamber C1 second level being connected, and the second level holds dirt chamber C2 as last
One-level is held dirt chamber and communicated with box-type oil seal 2.The gap δ 1 that first order appearance dirt chamber C1 leads to exterior space is wheel hub 3 and braking internal tooth
Self-assembling formation after shell 1 assembles, gap δ 1 size depend on wheel hub 3 and brake the design size of inner tooth shell 1.Through 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, that is, hold dirt chamber C1 loop configuration near the side on ground；And gap δ 1 near-earth side axle is to holding dirt chamber C1's
Near-earth side is connected so that can be discharged positioned at the dust for holding dirt chamber C1 near-earths side along gap δ 1.On the other hand hold with the second level
The gap δ 2 that dirt chamber C2 is connected is then positioned at position of the side wall by centre for holding dirt chamber C1 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
Dirt chamber C2 dust 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-use function.
The specific environment that the present invention can make according to wet braking turner, change wheel hub and brake the knot that inner tooth shell is engaged
Structure so that form more than two appearance dirt chambers after wheel hub and braking inner tooth shell cooperation, further enhance dust-proof effect.
The present invention is by changing wheel hub and braking the structure of inner tooth shell so that wheel hub and braking inner tooth shell are after the completion of assembling
Some appearance dirt chambers are internally formed, the dust of intrusion is collected by holding dirt chamber.Formed after wheel hub and braking inner tooth shell assembling
The axial slits communicated with exterior space are held dirt chamber with the first order and communicated；And dust can be accumulated in hold dirt chamber under gravity
Near-earth side, and then dust is then exhausted from along axial slits；Upper level appearance dirt chamber leads to the appearance dirt chamber of next stage
Gap 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 improves
Dust-proof effect.
