[0031] Figure 1 shows a schematic representation of the stabilizing device, object of the invention, showing in it the parts and elements it comprises. The wheel 100 mounted in cam attached shaft 106; the pump 105 mounted over cam. The compressed air 101 transferred to control device 102; control device controls the pressure and flows to the tire 107; sensing device 104 mounted to sense air pressure into the tire.

[0032] Figure 2 shows a perspective view of an example in which the wheel mounted in the cam attached shaft. Cam going to press the pump to compress air; the control and sensing units will be attached to maintain pressure in the wheel.

[0033] The vehicle is a motorcycle to which the device according to the invention has been incorporated, a possible option being appreciated in the arrangement of the elements it comprises coupled in a said motorcycle.

[0034] Figure 3 .- Shows a perspective view of the axis of the device of the invention where the air passage bore and the connections to the bushing at the upper end and the fitting fixed at its lower end is appreciated.

[0035] The device proposed by the present invention aims to solve the problem described above, taking advantage of the implementation of a hub with an air passage system on its wheels and a small number of elements that, coupled to said bushings, are incorporate the vehicle and whose weight is not relevant.

[0036] As is known from the aforementioned documents, air can circulate in both directions through the motorcycle hub with the wheel spinning at any speed. Thus, taking advantage of the fact that the air is in the tires and can exit and enter through the hub and the wheel axle, the device of the present invention contemplates, as an essential element thereof, the incorporation of a safety or relief valve coupled in Any part of the motorcycle, so that it is conveniently connected to the aforementioned air system of the hubs and regulated to the required pressure, releases the excess air when it exceeds the established pressure and for the reasons already stated. In this way it is not necessary to make any adjustment or check of the pressure either before or after the race, it is simply regulated to the desired atmospheres or the valve is responsible for maintaining it. Logically up to this point, the device only manages to maintain the continuous pressure, nor can it be raised or lowered, although simply with this it is already possible to simplify and provide improvements in the pressure adjustment and in turn provide greater safety to the pilots

[0037] Additionally, and in a referred way, the device also has a manometer with good reading, connected to the air circuit employing the corresponding fittings used in the pneumatic industry, which is placed in a strategic and visible place for the pilot, so that you can see the tire pressure at all times.

[0038] Also, according to another additional feature of the invention, the device contemplates the incorporation of a button connected to the air circuit, so that, when pressed, it releases air to the outside and therefore lowers the pressure. This button, preferably, is installed near the handles, so that the pilot accesses easily to it.

[0039] With this, what is further achieved is that when the pilot considers it appropriate for any circumstance, whether due to tire wear or rain, he can press the button and lower the pressure (never go up) and thereby modify the contact surface of the tire with the asphalt, thus achieving greater grip in curves and greater stability in driving in general. This simple gesture can be crucial when there are few laps left to finish the race. It should be noted that the preferred option of the invention contemplates a bushing with air system in each of the two wheels of the motorcycle, as well as two pressure gauges and two buttons connected to the circuit, to independently control and regulate the pressure of each of the two tires on both wheels.

[0040] It should also take into account the possibility that the tires in the race have some small leakage of air through the relief valve, example of this would be the deformation and oppression of the tire on the asphalt in braking, a rebound of the tire on the asphalt or several, the lying of the motorcycle or simply a small leak through the installation, this would mean a progressive loss of air pressure not required by the pilot.

[0041] Therefore, the air circuit, according to the preferred embodiment of the device of the invention, is fed and connected to a small air tank with a pressure regulator to provide the air that is lost by the aforementioned concepts. Said pressure regulator is incorporated between the air circuit and said tank, which tank has two outputs, one for each circuit, with two regulators, one for each tire, since, as noted, the device contemplates the inclusion of air system to the tires through the hub on both wheels.

[0042] Additionally, so that the pilot can lower the pressure of any tire at will due to the circumstances that suit him, the device includes the incorporation of an air switch, installed in an accessible place, so that the pilot can operate it and isolate the tank so that does not provide pressure while it is desired that the pressure drops due to the need for piloting.

[0043] It should be noted that the materials of the pieces, as well as their shape and size, may vary depending on the needs of the installation.

[0044] With all this, the described device allows keeping the pressure in competition motorcycle tires stabilized and thus obtain the advantages that this entails. On the other hand, in the case of spoke wheels, preferably, the air ducts that connect the hub with the tire are internal or semi-internal, of the same material as the rest of the tire, these ducts being able to be in a radius or several. Preferably, they will go from the outside of the tire to the inside of the hub. When the tire is mounted on the rim and the hub with all its parts sealed, the air can circulate from inside to outside or vice versa.
