Definitions
- the technical sector of the present invention is that of inflation and deflation systems of a vehicle wheel.
- valve system is particularly suitable for heavy vehicles, such as trucks, military vehicles, public works or civil security vehicles.
- This system must be adapted when it is to be applied to light vehicles.
- the disadvantages of this system in the case of these light vehicles reside first of all in the fact that the dismantling operations of the wheel and / or of the valve always cause the deflation of the tire, which makes the phases particularly problematic and uncertain. wheel balancing. The user or the manufacturer is therefore obliged to install an isolation valve to avoid re-inflation of the wheel.
- valve and its connection remain accessible from the outside and are subject to theft and deliberate theft (vandalism) or accidental (impact on the rim).
- the object of the present invention is to propose a new organization for integrating a valve in a wheel making it possible to maintain the inflation pressure prevailing in the tire during mounting or dismounting of the wheel and / or of the valve.
- the subject of the invention is therefore a self-sealing device for the tire of a vehicle wheel equipped with an inflation and deflation valve for the tire while ensuring its supply of compressed air using a pressure circuit.
- the valve is disposed between the wheel and the wheel hub and in that it comprises a closure means integrated in the wheel supply circuit, said means being actuated in the open position in the presence of the valve and in the closed position in the absence of the valve.
- the open position designates a state of the closure element for which air can pass from the valve to the tire as well as from the tire to the valve.
- the sealing means consists of a finger extended by a frustoconical part, movable under the action of a spring inside a bore formed in the wheel supply circuit, said frustoconical part being able to be applied to a seat having a frustoconical profile under the action of the spring to close the wheel supply circuit.
- frustoconical form is taken here by way of example.
- Other means, such as a planar or spherical shape can be envisaged, but for a better legibility of the invention it is this example which will be used to explain the principle of the invention.
- the valve consisting of a valve body and a cover, forms a housing delimited by the hub and the seat, both provided with communication means to allow the supply of compressed air to the wheel from a rotary joint, the seat being arranged at the wheel and the valve cover at the hub supporting the wheel.
- valve is arranged in such a way that its axis of symmetry coincides with the axis of rotation of the wheel.
- shutter means is arranged to act axially with respect to the wheel.
- valve is screwed into the hub.
- seat is provided with an indexing member relative to the hub, the indexing member, or locating, can, for example, be a pin or a screw.
- the closure means is always arranged to act axially, but the valve is fixed to the rim by means of pressure screws.
- the shutter means is arranged to act radially with respect to the wheel.
- valve seat is provided with a substantially frustoconical extension intended to cooperate with the closure means, said extension being provided with means of communication between the valve and the wheel, and in that the wheel is closed externally.
- the valve is held by friction in the base.
- friction is meant a relationship allowing the valve to be easily inserted into the bore (for example a sliding pivot relationship) but of which an O-ring seals the assembly.
- the seat is provided with a substantially cylindrical extension capped by a plug provided with a frustoconical part intended to cooperate with the closure means, said plug being screwed onto said extension, and in that the wheel is open externally.
- a plug provided with a frustoconical part intended to cooperate with the closure means, said plug being screwed onto said extension, and in that the wheel is open externally.
- a very first advantage of the present invention lies in the fact that the tire pressure is retained even when the wheel or the valve are removed.
- Another advantage lies in the possibility of balancing without a tedious disassembly of the valve, the balancing being carried out on an apparatus of any type.
- Another advantage lies in the quick and easy disassembly of the valve after disassembly of the wheel.
- Yet another advantage of the invention lies in the fact that the entire system remains inaccessible from the outside, which prevents damage to the valve.
- Yet another advantage lies in the fact that the central position of the valve makes it not very sensitive to centrifugal forces, which improves its reliability and its service life.
- Yet another advantage lies in the technical implementation of the very simple assembly and in the minor modifications to be made to the wheel or its support.
- FIG. 1 is a diametrical section of the wheel and of all of its components according to a first configuration
- FIG. 2 is a partial enlarged view of FIG. 1,
- FIG. 3 is a partial section showing an example of a shutter means
- FIG. 6 is a partial section illustrating another variant of the valve assembly.
- Figure 1 which shows a section of a wheel mounted on its rotational drive shaft
- the wheel 1 consisting of a rim 2 and a tire 3.
- the rim 2 is connected to its support shaft 4 via a hub 5.
- Two bearings 6a and ⁇ b are conventionally interposed between the shaft 4 and the hub 5.
- These bearings 6 conventionally comprise an external cage 7 and an internal cage 8 between which is disposed a rotating joint 9 to allow communication of pressurized fluid between an external source 10 and the tire 3 as will be explained below in relation to FIG. 2.
- the rim 2 is mounted, in a conventional manner, on the hub by means of bolts, a housing 11 of which is visible in the figure.
- a valve 12 is mounted in the hub 5 and according to the invention it comprises a valve cover 13 screwed into the hub 5 and a seat 14, the valve being indexed relative to the hub by means of a screw 15.
- This screw allows the valve 12 to be indexed relative to the hub to ensure continuity of the fluid circuit as explained below.
- a brake disc 16 integral with the hub 5.
- the brake disc is provided with grooves 63 allowing the air to escape, in accordance with the operation of the valve explained in the previously cited patents.
- the rim 2 is equipped with a radial duct 17 and an axial duct 18 allowing fluid communication between the valve 12 and the tire 3 along the arrow F.
- a closure means 19 interposed in the axial duct 18, intended to cooperate with the seat 14 of the valve.
- the closure means therefore occupies an axial position in this configuration and is in the open position.
- the fluid circuit between the source 10 and the tire comprises, in addition to the conduits 17 and 18, a first axial conduit 20 followed by a radial conduit 21 and a second axial duct 22 formed in the seat 14, an axial bore 23 and a radial duct 24 formed in the hub 5, a slot 25 delimiting the internal cage 8 in two parts, a conduit 26 formed in the outer cage 7 and a conduit 27 formed in the shaft 4.
- these different conduits are provided to communicate with each other during the mounting of these different elements.
- the bore 23 is tapped to receive the valve 12 by screwing.
- the passage of air which will successively pass through the duct 27, the rotary joint 9, the rotary joint 25, the slot 25, the duct 24, is controlled in a known manner.
- the circuit described above is controlled under vacuum using adequate means.
- the inflation and deflation control means can be those described in patent FR-2731655. They can be used as is without significant modification. It is therefore not necessary to describe them in detail.
- seals are provided to prevent possible leaks and maintain the pressure in the tire at the desired value.
- FIG. 3 there is shown in section an embodiment of the shutter means 19.
- This comprises a pin 30 whose free end is supported on the seat 14 and which extended at the other end by a frustoconical part 31 on which an elastic element 32 acts, for example a helical spring.
- This spring 32 is for example applied against the bottom of the conduit 18.
- a stop 33 is provided with a conical flare 34 of the same configuration as the part 31.
- the stop 33 is maintained in place using an insert 35 fixed to the rim 4.
- O-rings 36 are integrated in the rim 4 and the seat 14 to seal between the insert 35, the rim 4 and the seat 14. The operation is as follows.
- the shutter 19 lets air pass (in one direction or the other) only when the seat 14 actuates the finger 30, that is to say when the valve is mounted on the rim, thus allowing circulation air between line 21 coming from the valve 12 and the conduit 17 communicating with the tire 3.
- the spring 32 pushes the finger 30 towards the outside of the bore 18, so that the part 31 comes into intimate contact with the conical surface 34.
- the tire 3 is kept under pressure by closing the circuit and the balancing or intervention operations on the means are possible without loss of pressure.
- One of the roles of the insert 35 being to ensure the sealing of the system between the moment when the finger 30 is actuated and the moment when the valve is fixed in a completely sealed manner on the rim.
- FIG 4 there is shown an alternative embodiment in which the closure means is arranged in a radial position.
- the finger 30 is then placed in the radial duct 17 as well as a retainer 40 provided with a conical surface, the spring 32 bearing on a stop 41 fixed in the duct 17.
- the seat 14 extended by a thread 43 capable of being screwed onto the rim 2 in a bore 46 closed on the outer side and is provided with a ramp 48 on which the finger 30 comes to bear.
- This seat 14 is pierced with a radial duct 44 and an axial duct 45 communicating with one another.
- the radial duct 44 communicates with a chamber 54 delimited by the rim 2 and the seat 14, which in turn communicates with the radial duct 17.
- the axial duct 45 communicates with the valve body 13.
- This valve is isolated in its housing so conventional in the hub 5, for example using an O-ring 49.
- An O-ring 47 inserted in a housing formed in the rim provides sealing between the rim and the seat 14.
- a washer 50 called Belleville, ensures the clamping of the valve 12 and keeping it in position.
- the valve 12 is not screwed into the hub 5 but is linked by friction in the bore 23.
- the operation is as follows. When the rim is disassembled, the valve remains attached to it and it then suffices to unscrew the valve to separate it from the rim for balancing operations. As the valve is unscrewed, the finger 30 travels along the ramp 48 and it comes to bear against the conical surface of the retainer 40 by closing the fluid circuit. In the same way, when the valve is screwed on, the finger 30 travels along the ramp 48 and it moves away from the conical surface of the stopper 40 by opening the fluid circuit.
- FIG. 5 shows the mounting of a valve 12 having a configuration identical to that of FIG. 4 with the exception of the seat 14.
- the rim 2 is open towards the outside, that is to say that is, it has a hole 51 aligned with the bore 23 of the hub.
- the seat 14 is pierced with a radial duct 52 and an axial duct 53 communicating with each other.
- the conduit 53 communicates with the valve 12 and the conduit 52 communicates with a chamber 54 delimited by the rim 2, the seat 14 and a cap 55.
- This cap is screwed onto the end piece of the cover and is adjusted in the rim 2 in a leaktight manner using an O-ring 56.
- This cap comprises a ramp 57 on which the finger of the shutter comes into contact.
- This cap therefore realizes on the one hand the sealing of the chamber 54 towards the outside and on the other hand the maintenance of the opening of the shutter 19.
- Another O-ring 58 ensures the sealing between the seat 14 and the rim 2.
- the valve 12 is fixed to the rim by friction and it is the cap 55 which provides the partial fixing. This fixing is sufficient to maintain the valve and preserve it from stresses during handling operations. Total fixing is ensured by an elastic element 50 such as a Belleville washer.
- the valve body is also fixed by friction in the hub 5.
- the assembly is as follows. We start by introducing the valve 12 into the rim 2, then we introduce the cap 55 by screwing on the cover. As the screwing progresses, using three threads for example, the ramp 57 pushes the finger of the shutter 19 which opens the tire supply circuit. The system is ready to work, you can mount the wheel on the hub. Loosening the cap (a few turns) closes the pipe while holding the valve in place.
- An implementation variant is illustrated in the figure
- valve 12 is no longer fixed on the hub 5 but on the rim 2.
- the seat 14 of the valve is fixed on the rim 2 by means of 'A tubular insert 60 attached to the rim.
- the fixing of the cover is ensured by suitable connecting elements, for example three pressure screws located in the housings 62 adapted to this type of fixing.
- valve 12 is then housed in the bore of the hub 5, it produces friction.
