WHEEL ASSEMBLY WITH INTERNAL PRESSURE RESERVOIR AND PRESSURE FLUCTUATION WARNING SYSTEM

摘要

Method of allowing a control of a vehicle provided with at least two wheels in case of puncture of a tire, each wheel (1) comprising a rim (2) and a tire (3) associated therewith, said method comprising the steps of: inflating each tire (3) to an operating pressure (PE) at a reference temperature (TR); admitting a fluid compressed to a first pressure (PP) higher than the operating pressure (PE) of said tire at the reference temperature (TR), into at least one tank (4) associated with at least one of said rims (2); bringing said tire (3) into communication with said tank (4) when the inner pressure (Pi) of said tire is lower than said operating pressure (PE) by a predetermined first threshold value (Vs*); measuring the inner pressure (Pi) of said tire (3) with a predetermined frequency (F); calculating a variation (Vp) of said inner pressure (Pi) in the time unit; generating an alarm signal when said variation of the inner pressure (Pi) corresponds to a reduction and is higher than a predetermined value (VP*); transmitting said alarm signal to the driver.
