Pressure Monitoring and Adjustment for Two Wheeled Vehcile with Wheel Based Pressure Reservoir

A method of allowing control of a vehicle with at least two-wheels in case of puncture of a tyre, each wheel comprising a rim and a tyre associated therewith, comprising the steps of:

• inflating each tyre to an operating pressure;
• admitting a fluid compressed to a first pressure higher than the operating pressure of said tyre into at least one tank associated with at least one of said rims;
• bringing said tyre into communication with said tank when the inner pressure of said tyre is lower than a predetermined first threshold value;
• detecting a variation of an inner pressure of said tank;
• activating a pressure measuring device when said inner pressure variation corresponds to a reduction and is higher than a first predetermined value;
• measuring the inner pressure of said tank with a predetermined frequency (F) by means of said pressure measuring device;
• calculating a variation in said inner pressure in a time unit;
• generating an alarm signal when said calculated inner pressure variation corresponds to a reduction and is higher than a second predetermined value;
• and
• transmitting said alarm signal to the driver.

A vehicle having at least two wheels, comprising:

• at least one rim operatively associated with a tank adapted to be filled with a fluid to a first pressure;
• a tyre mounted on said rim and inflated to an operating pressure, said operating pressure being lower than said first pressure;
• at least one valve adapted to regulate communication between said tank and tyre so as to bring said tank and tyre into mutual communication when the inner pressure of said tyre is lower than a predetermined first threshold value;
• at least a device for detecting a variation of an inner pressure of said tank;
• at least a device for measuring the inner pressure of said tank with a predetermined frequency activable when said inner pressure variation corresponds to a reduction and is higher than a first predetermined value;
• at least one calculation unit to calculate a variation in a time unit of the inner pressure of said tank;
• at least one signal generator operatively associated with said calculation unit and capable of generating an alarm signal when said pressure variation corresponds to a reduction and is higher than a second predetermined value.

A wheel for vehicles, comprising:

• at least one rim operatively associated with a tank adapted to be filled with a fluid to a first pressure;
• a tyre mounted on said rim and inflated to an operating pressure, said operating pressure being lower than said first pressure;
• at least one valve adapted to regulate a communication between said tank and tyre so as to bring said tank and tyre into mutual communication when the inner pressure of said tyre is lower than a predetermined first threshold value;
• at least a device for detecting a variation of an inner pressure of said tank;
• at least a device for measuring the inner pressure of said tank with a predetermined frequency activable when said inner pressure variation corresponds to a reduction and is higher than a first predetermined value;
• and
• at least one calculation unit to calculate a variation in a time unit of the inner pressure of said tank,
• said calculation unit being associable with a signal generator for generating an alarm signal when said pressure variation corresponds to a reduction and is higher than a second predetermined value.
