- this connecting tube is intended to transmit only a pressure, and not a flow
- this connecting tube is intended to transmit only a pressure, and not a flow
- Brass tubes on the other hand, have good resistance for this use, but they have the disadvantage of breaking easily when they are forced to follow the internal profiles, sometimes complicated, of the alloy rims.
- a good solution consists in retaining a copper capillary tube, with an outside diameter of the order of 2.5 mm, and an inside diameter of the order of 0.6 mm. Enough ⁇ gide to offer all safety during rotation. wheels, it nevertheless remains malleable enough to be easily shaped, given the complex trajectories presented by alloy rims
- this connecting tube must be permanently connected to the tire.
- the rim (3) is pierced with a hole into which engages a castle nut (4).
- the castle nut protrudes from the rim by only 2mm and it is ultimately the tube 0 2.5 which, once folded in the slots, constitutes the maximum protrusion.
- a threaded piece (1) is screwed in the center of which the connection tube (2) has been brazed. It is then folded along the rim (3).
- the connecting tube (2) is finally folded against the rim.
- This space-saving and inexpensive solution has the main advantage of being very effective since the sealing is accomplished on a cylindrical surface several millimeters long at each end of the sleeve, and not on a line as in most fittings.
- Tire inflation control device for vehicles consisting of a rim, an inflatable tire and an inflation valve for the tire, comprising a pressure gauge disposed in the center of the wheel and coaxial with it and comprising at least one mark or symbol such as a colored sector corresponding to a normal inflation pressure (or pressure range), and a connecting tube for connecting the pressure gauge to the tire, characterized in that said tube is connected to a fixed valve to said rim, which valve comprises a main body (1) and preferably said valve is engaged in a circular seal (8) placed in the valve hole of the rim, and said wheel comprises a sleeve (3) of alloy of copper or zinc such as brass on which is brazed said copper tube (2), which sleeve is engaged around said valve body and compresses said seal (8), which valve comprises a nut (7) for fixing the man chon (3) via a conical washer (6) compressing a seal (5).

- a safety valve cap comprising, according to FIG. 6, a flange (3), made of plastic for example, with a rupture initiator at (3 '), the cap (1 ) coming to screw on the end of the valve (6). It is pierced in its center with a bore in which a core (2) takes place.
- a seal (4) seals between (1) and the end of the valve (6).
- a central channel is drilled in the axis of (2) and communicates with a fitting (5) which brings the pressure to the manometric system fixed in the middle of the hubcap.
- This assembly is to be retained preferably for the use on tires of heavy goods vehicles taking into account the high pressure which one meets there.
- valve (7) of the valve (6) no longer being requested to open, closes with its return spring, so that the tire can continue to roll without any loss of pressure, which was necessary .
- the tensile strength of the various joining elements is calculated in such a way that the weakest is located at the level of the breaking point (3 '). From then on, we are sure that the continuity solution will operate at this level and that the valve flap (7) will close at each request.
- This assembly can be envisaged for light vehicles whose tire pressure does not exceed 2.5 bar.
- FIG (5) it consists of a plug (1) which is screwed onto the end of the valve (6). It is pierced in its center with a bore in which a core (2) takes place. An O-ring (3) seals between (1) and (2) and is inserted into the two circular grooves, made both in (1) and (2).
- the circular groove of (2) is calculated in such a way that the end of (2) comes to open the valve flap at the end of the stroke.
- a seal (4) seals between (1) and the end of the valve (6).
- a central channel is drilled in the axis of (2) and communicates with a plastic tube (5) which brings the pressure to the center of the hubcap.
- valve (7) of the valve (6) no longer being requested to open, closes with its return spring, so that the tire can continue to roll without any loss of pressure, which was necessary .
- the tensile strength of the various junction elements is calculated in such a way that the lowest is located at the joint (3). From then on, we are sure that the continuity solution will operate at this level and that the valve flap (7) will close at each request.
- valve flap will be opened again and it will become possible to inflate or deflate the tire with minimal handling.
- the adapter being a small piece
- a ring (3) is provided so that it can be mounted on the key ring of the vehicle, and therefore avoid being lost.
- Tire inflation control device for vehicles consisting of a rim, an inflatable tire and an inflation valve for the tire, comprising a pressure gauge disposed in the center of the wheel and coaxial with it and comprising at least one mark or symbol such as a colored sector corresponding to a normal inflation pressure (or pressure range), and a connecting tube for connecting the pressure gauge to the tire, characterized in that said wheel also comprises at least one second valve mounted on said rim or on a sail hubcap of said rim.
- a valve On one of the spokes from its center, is still theoretically possible. But a valve occupies a significant length and the maximum space available, under a hubcap, is located in the center of the rim web. This center continuing to be occupied by the manometric device, there remains the casing of this manometer, or at least its envelope.
- This assembly is therefore permanently connected to the original valve, always by means of a separable safety valve cap constantly putting the system under pressure.
- the latter opens the valve flap and allows the pressure to be adjusted, while continuing to display this parameter.
- the center of the hubcap being the area least subject to dust projections from the brake linings
- Tire inflation control device for vehicles consisting of a rim, an inflatable tire and a tire inflation valve, comprising a pressure gauge arranged in the center of the wheel and coaxially with it and comprising at least one mark or symbol such as a colored sector corresponding to a normal inflation pressure (or pressure range), and a connecting tube for connecting the pressure gauge to the tire, characterized in that the valve comprises a ring or a threaded sleeve internally and externally threaded, the diameter and / or the pitch of the internal and external threads of said ring being different, which ring is screwed onto said valve and is retained by a mechanical brake means such as a bonding or a spring, preferably consisting of at least three portions or sectors of said ring which are separated by at least three notches and are clamped by radial deformation.
- a mechanical brake means such as a bonding or a spring
- a manometric cover is easily installed on a steel rim and can be removed just as easily.
- an easy deterrent against any loan consists in screwing on the valve a brass sleeve, externally threaded, and made non-removable by gluing or mechanical braking.
- Two nuts are provided for the disassembly of this sleeve, making it possible to act as a nut and a lock nut by mutual locking in order to unscrew it. But these nuts are only supplied with the manometric cover.
- the original supply will include this sleeve. However, it can only be given as a replacement on presentation of the initial invoice.
- the supply will also include one sticker per wheel, to be placed on each hubcap, and specifying that this assembly cannot be reused on another rim, this in order to warn the borrower of the uselessness of his action.
- Tire inflation control device for vehicles consisting of a rim, an inflatable tire and an inflation valve for the tire, comprising a pressure gauge disposed in the center of the wheel and coaxial with it and comprising at least one mark or symbol such as a colored sector corresponding to a normal inflation pressure (or pressure range), and a connecting tube for connecting the pressure gauge to the tire, characterized in that said pressure gauge comprises at least one movable reflector , mechanically integral with said needle and / or with the mechanism for driving in rotation of said needle, which reflector may or may not be a polarizer, which reflector is preferably substantially planar or extends along a cylindrical or toric surface and is arranged to axially or radially with reference to the axis of rotation of the wheel and / or to the axis of rotation of the needle, to allow detection of the position needles with respect to screens hiding or not reflecting surfaces thanks to an optical transceiver, operating by laser emission or by uncoordinated radiation, preferably working in the infrared field, located fixed (on the ground)
- Transmitters located to the left and right of the passages for vehicles, send radiation fields at the level of the wheels.
- the radiation is deflected by the two reflectors (1) supported by the twin needle (2), towards receivers, so that the presence, or absence, of these reflectors allows to assess in passing the state of pressures.
- the width of the colored sectors has been significantly reduced compared to that used in the first patent.
- the interruption of radiation corresponds to an alarm
- the user will be warned of an anomaly in the system.
- it will suffice to check the state of the pressures by observing its wheels stationary and, at the same time, the state of cleanliness of the lids (9). It is noted that the lids (9) are normally centrifuged by the rotation of the wheels and that only the deposits of mud are capable of causing an operating anomaly.
- the system therefore works with the visible reflectors in normal state, ie needle (2) on the orange (5) and green (6) sectors, and with gradual disappearance of the reflectors (1) when the needle goes towards the red sectors ( 4) due to a drop in pressure.
- a light panel will light up to indicate to the driver if it is necessary to re-pressurize the tires, this warning may be supplemented by an audible alarm if necessary.
- transceiver (ER thereafter) fixed at the level of the wing of the vehicle, and in a direction corresponding to a geometric radius of the pressure gauge, making it possible to obtain an alarm inside of the vehicle.
- two reflectors (7) are thus arranged on two pallets (8) situated at the ends of the needle (2) and in a plane perpendicular to the latter.
- These reflecting surfaces can adopt various curvatures, taking for example the shape of a plane, a cylinder or even a torus.
- the fixed ER on the wing is preferably placed vertically on the wheel hub, exits in an area allowing the vertical movement of the suspension without the aiming being disturbed by this movement
- the information, captured on each wheel, is thus transmitted to an electronic central unit, taking into account the time base and the speed of the car before delivering an alarm signal
- Vehicle tire inflation control device comprising a rim, an inflatable tire and a tire inflation valve, comprising a pressure gauge comprising at least one reference or symbol such as a colored sector corresponding to a pressure (or pressure range) normal inflation of the tire, characterized in that said pressure gauge is arranged eccentric, with reference to the axis of rotation of the wheel, and is preferably fixed to the rim near the periphery thereof Ci, for example screwed at the end of the valve fitted to the rim or else connected to the valve by an extension with an adjoining valve which can only be screwed into it by interposing a brass end piece made disassemblable by spring effect, said pressure gauge also being made non-removable by rotation of the central part, tapped with the pitch of the valves, relative to its base due to the absence of a locking rod, the only one capable of solida ⁇ ser these two parts.
- a pressure gauge comprising at least one reference or symbol such as a colored sector corresponding to a pressure (or pressure range) normal inflation of the tire,
- this assembly can be envisaged According to FIG. 12, instead of the valve caps, one can screw manometric systems (1) with bitter central connection making it possible to assess, by means of colored sectors (2), the state of the pressures of its tires In order to complete the device, it is possible to add thereto, fixed on the forks (4) seen in section, and at the height of the valves, radiation ERs (5) coming to be reflected, through windows (3), on the ends. needles (6). The detection is therefore of the radial type and the preceding provisions apply to it.
- FIG. 13 An exemplary embodiment in radial detection is shown in FIG. 13.
- a crown (4) and the base (5) enclose the lower part of the cover (3) by means of screws (6), in order to immobilize it so that the end of the needle is located between the orange and green sectors, once the system is pressurized, this adjustment being made once and for all to display the operating pressure.
- This base (5) contains a metal socket (7) screwing onto the valve (8).
- This socket (7) comprises a part (9) permanently opening the valve flap.
- a seal (1 ') seals between the pressure tap of (1) and (5).
- Another seal (10) prevents any leakage between (5) and (7).
- Nipple screws (12) secure (5) and (7).
- the operating pressure is thus displayed by tightening the screws (6) on the one hand, and by tightening the system on the valve (8) on the other hand, it is not at all certain that the window is opposite the ER.
- the system must be turned by hand so that the window is facing the ER, this without loss of pressure, which is possible thanks to the seal (10).
- the groove containing the seal (10) is calculated in such a way that the mechanical friction introduced by this seal is sufficient to prevent any subsequent rotational movement of the assembly in order to maintain this adjustment during the rotation of the wheel.
- the end of this rod has a reduced diameter, in correspondence with the drive hole drilled in (7).
- This end can finally be threaded, the corresponding hole of (7) being tapped, so that to unscrew the system you must have the rod with two diameters, the smallest being invisible from the outside, with an invisible thread too, with an unknown pitch and diameter.
- This rod essential for using the system, is provided with a ring allowing it to be mounted on the key ring of the motorcycle.
- a variant consists in using the sleeve described in 2.7, making it impossible to reuse the system on another wheel.
- extensions comprising a bypass tee on which a valve is brazed.
- This assembly brings the end of this annex valve to 25mm at most of the axis of the extension, so that a tire at least 50mm wide is needed so that this valve can be protected from curbs, which is generally the case for motorcycles.
- the subject of the present invention is a vehicle tire inflation control device, composed of a rim, an inflatable tire and a tire inflation valve, comprising a pressure gauge comprising at least one reference or symbol such as '' a colored sector corresponding to a normal inflation pressure (or pressure range) of the tire, characterized in that said pressure gauge is disposed eccentrically, with reference to the axis of rotation of the wheel, and is preferably fixed to the rim near the periphery thereof by means of a connecting piece, removable or coming from the foundry.
- a vehicle tire inflation control device composed of a rim, an inflatable tire and a tire inflation valve, comprising a pressure gauge comprising at least one reference or symbol such as a colored sector corresponding to a normal inflation pressure (or pressure range) of the tire, characterized in that said pressure gauge is disposed eccentric, with reference to the axis of rotation of the wheel, and is preferably fixed to the rim at proximity of the periphery thereof by means of a connecting piece making it possible to orient and then block the manometric system around its axis of symmetry.
- this lug (6) must allow the pressure gauge (3) to enter the rim gauge (2), this in order to avoid curbs.
- this lug (6) must also avoid the disc brakes (5) of the disc brakes.
- the pressure gauge is screwed in such a way that the radial force (10) acts in the direction of decreasing pressures, either by bringing its end towards the center of the pressure gauge
- the pressure gauge housing is thus immobilized in this position by means of two needle screws (8) (see Figure 14 showing a partial view from the right)
- Figure 17 shows the device as seen by the user
- This lug (6) provided coming from fonde ⁇ e, can just as easily be an independent part of the rim, This deflector is interesting to consider for steel rims which would not withstand sufficient deformation, coming from forge, to constitute a lug
- the pressure gauge (3) is operated as before by mechanical locking, for example by means of needle screws (not shown on plate 7/8)
- this lug (6) is held on the rim (14) by means of a screw (11) locked by a fan washer (12) A seal (13) seals between (6) and the rim (14)
- a rubber or plastic cap covers the head of the screw (11) in order to prevent the tire bead from being damaged when the casing is mounted on the rim (not shown in Figure 18)
- Maintaining the lug (6) on the rim (14) can also be done by ⁇ vetage, by welding or any other means
- the rim web is notched in (15) to allow the installation of the pressure gauge (3), this notch having to be produced in se ⁇ e during the manufacture of the rim web.
- the imbalance on the rim, caused by the presence of the device, is of the order of 100 grams II therefore enters the balancing possibilities of machines which accept at least 150 grams
- the present invention relates to a vehicle tire inflation control device, composed of a rim, an inflatable tire and a tire inflation valve, comprising a pressure gauge disposed in the center of the wheel and coaxially with the latter, comprising at least one reference or symbol such as a colored sector corresponding to a normal pressure (or pressure range) for inflating the tire, characterized in that the needle of the said pressure gauge is replaced by a pallet or disc rotary, fixed perpendicular to the axis of rotation of said needle, and driven by the mechanism of the pressure gauge in case of pressure variation, pallet or disc on which a drawing appears.
- Car manufacturers are used to placing their mark on the front of the engine hood, on the trunk and on the sides, in the center of the wheel trims or light alloy rims.
- This pallet or disc then rotates as a function of the pressure variations exerted in the tires and makes it possible, thanks to peripheral indexes such as colored sectors, to display the value of this parameter permanently, by providing the observer with a modulated signal.
- the mark (4) indicates the rotating disc, fixed perpendicular to the axis of rotation of the needle, and on which the lion is printed.
- This figure 19 thus shows that the pressure is correct since the lion's head is in the zone (1).
- Figure 20 shows that the lion has rotated, indicating a characteristic underinflation since the head is in zone (2).
- FIG. 21 represents a noticeable drop in pressure, requiring immediate re-pressure since the head is in zone (3).
- This improvement can be applied to other vehicles such as heavy goods vehicles or motorcycles.
- markers other than colored sectors, can be used to materialize the various zones relating to the phenomenon of underinflation.
