Description
Technical field
The present invention relates to automatic tire inflation system field, and in particular to a kind of Single-channel Rolling sealing device assembly.
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 two ends
And fit 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 there is service life, long, fault rate is not high
Shortcoming.
The content of the invention
The purpose of the present invention is kept away aiming at a kind of the not enough there is provided Single-channel Rolling sealing device assembly of above-mentioned technology
Exempt from central siphon Radial Perturbation, reduce the abrasion during sealing ring is rotated, lift the stability of Single-channel Rolling sealing device assembly and prolong
Long life.
To achieve the above object, the Single-channel Rolling sealing device assembly designed by the present invention includes flexible joint part and rotation
Transfer part point, the flexible joint part includes be flexible coupling assembly and the blocking with the assembly endoporus interference fit that is flexible coupling, described
It is flexible coupling in the endoporus of assembly and is closed with float cushion, central siphon and the first y-shaped ring successively from the inside to the outside, the rotating part subpackage
Adapter body and one end is included to be connected and sealed by the first O-ring seal with the assembly external screw thread that is flexible coupling by internal thread
Central siphon adapter, the central siphon adapter other end is fixed in the adapter body endoporus using self-lubricating bearing, and
Sealed using the 3rd y-shaped ring, the adapter body endoporus other end is threaded with gas-tpe fitting, the gas-tpe fitting
For gas outlet, it 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
It is provided with inner card cage in the second y-shaped ring, the exterior bayonet slot and the second O-ring seal is installed, 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.
The operation principle of the present invention 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 central siphon reeve is fixed in the part of axle end, the sealing ring in the part
With central siphon formation palette, turn while making the flexible joint part not produce by the fit of the part spline neck
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, does not result in the abrasion of sealing ring.
In addition, when vehicle wheel rotation, when vehicle wheel rotation, the adapter body concomitant rotation, the self-lubricating bearing
Stablizing relatively for 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, stable sliding friction is produced, sealing ring is in the use state
Lower long lifespan, and performance is stable.
The present invention compared with prior art, with 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, it is ensured that sealing ring works in the state of more optimizing, and adds the matter of Single-channel Rolling sealing device assembly
Stability is measured, service life is extended, it is ensured that the practicality of tire inflation system.
