Description
Technical field
It the utility model is related to automatic tire inflation system field, and in particular to a kind of Single-channel Rolling sealing device is total
Into.
Background technology
At present, the construction of the wheel side Single-channel Rolling sealing device of known tire inflation system is by stainless steel shaft
Pipe, rubber seal and attached metallic element composition, central siphon are installed on the center of axle end, and sealing ring is in central siphon both ends
And be bonded therewith, when tyre rotation, rotated by the faying face of sealing ring and central siphon, it is airtight under rotation status to reach
Property, make endoporus UNICOM of the pressure-air by central siphon, from vehicle bridge delivered inside to tyre valve.But due to tyre rotation
During, center of rotation can always have certain axial dipole field relative to axle center, therefore central siphon can produce Radial Perturbation,
Sealing ring rapid wear under such a disturbance, easily produces gas leakage, and causing the structure to exist, service life is not long, fault rate is high
Shortcoming.
The content of the invention
Deficiency of the purpose of this utility model aiming at above-mentioned technology, there is provided a kind of Single-channel Rolling sealing device is total
Into avoiding central siphon Radial Perturbation, reduce the abrasion during sealing ring rotates, lift the stability of Single-channel Rolling sealing device assembly
And increase the service life.
To achieve the above object, the Single-channel Rolling sealing device assembly designed by the utility model includes flexible joint part
And rotating part, the flexible joint part include be flexible coupling assembly and the blocking with the assembly endoporus interference fit that is flexible coupling,
It is closed with float cushion, central siphon and the first y-shaped ring, the rotating part in the endoporus of the assembly that is flexible coupling successively from the inside to the outside
Dividing includes adapter body and one end is connected and by the first O-ring seal by internal thread with the assembly external screw thread that is flexible coupling
The central siphon adapter of sealing, the central siphon adapter other end are fixed on the adapter body endoporus using self-lubricating bearing
In, and sealed using the 3rd y-shaped ring, the adapter body endoporus other end is threaded with gas-tpe fitting, the gas
Pipe joint is gas outlet, can be connected with the tracheae of special connection tyre valve.
Preferably, the self-lubricating bearing is fixed by shaft block ring, and the self-lubricating bearing is arranged on institute by cushion block
State on adapter body.
Preferably, the self-lubricating bearing outer ring is fixed by end cap, and the end cap is provided with inner card cage and exterior bayonet slot, described
Second y-shaped ring is installed in inner card cage, the second O-ring seal is installed in the exterior bayonet slot, the end cap uses steel wire
Back-up ring is fixed in the adapter body endoporus.
Preferably, it is nested with the adapter body and sealing gasket and dust cap is installed, plays dustproof and waterproof, described turn
Change on fittings body end and be stamped top cover.
Preferably, the assembly that is flexible coupling is band wire sheathing tracheae, when radial direction produces slight perturbations, the soft company
The active force that such a disturbed belt comes can largely be eliminated by connecing the flexibility of assembly in itself.
Preferably, one end that the central siphon adapter is fixed in the adapter body endoporus is optical axis.
Operation principle of the present utility model is as follows：
Added in use, the adapter body is mounted by means of bolts on into repacking using the top closure
The hub for vehicle wheel of mounting hole is covered, and the central siphon is injected and is fixed in the part of axle end, the sealing ring in the part
Palette is formed with the central siphon, while the flexible joint part is not produced by the fit of the part spline neck and turns
Dynamic, pressure-air is entered by the tracheae in axletree, then enters swivel joint inner air path by the central siphon.
When vehicle wheel rotation, the assembly that is flexible coupling produces slight perturbations in radial direction, but described is flexible coupling assembly in itself
Flexibility can largely eliminate the active force that such a disturbed belt comes, and the now central siphon and first y-shaped ring two
Individual part geo-stationary, does not produce pivoting friction, will not cause the abrasion of sealing ring.
In addition, when vehicle wheel rotation, when vehicle wheel rotation, the adapter body concomitant rotation, the self-lubricating bearing
The relatively stable of central siphon adapter position during rotation is ensure that, Radial Perturbation, institute will not be produced with the adapter body
The inside and outside mounting surface of the 3rd y-shaped ring is stated in rotating coaxially, produces stable sliding friction, sealing ring is in the use state
Lower long lifespan, and stable performance.
The utility model compared with prior art, has advantages below：
By be flexible coupling assembly and the self-lubricating bearing, the close of the central siphon Radial Perturbation and rotating band is eliminated
Seal excessive wear, ensure that sealing ring works in the state of more optimizing, add the matter of Single-channel Rolling sealing device assembly
Stability is measured, service life is extended, ensure that the practicality of tire inflation system.
