DEVICE FOR MONITORING THE PRESSURE IN MOTOR VEHICLE PNEUMATIC TYRE Russian patent published in 1994 - IPC

FIELD: transport mechanical engineering. SUBSTANCE: two variants of the device are available. According to the first variant, the device has primary inductance coil 2, electric pressure transducer 3 installed on wheel rim 1, secondary inductance coil 5, permanent magnet 4 and alarm 6 installed on the stationary part of the vehicle. According to the second variant, the device uses additional inductance coil 7 installed on the wheel rim. The offered device can be mounted on a vehicle and, in particular, on cars and trucks with-out any considerable difficulty or any reconstruction of wheels and tyres. EFFECT: reduced failure of tyre as a result of mechanical injuries causing the decrease of pressure in tyre. 2 cl, 2 dwg
