Abstract

A device (1) for measuring tyre wear having an ultrasound emitter (2) and an ultrasound receiver (3) such that, emission by the emitter (2) of an ultrasound wave through a material of the tyre (10) and the reception by the receiver (3) of the wave after bouncing against the rolling surface (SR), a distance between the inner face (10i) and the rolling surface (SR) of the outer face (10e) is obtained. The frequency of the ultrasound wave is between 100 kHz and 500 kHz. The invention further discloses a tyre having the device (1), as well as a method for measuring tyre wear using the device (1).

Dependent claims

A device (1) for real-time tyre wear measurement, for a tyre (10) comprising an inner face (10i) and an outer face (10e), the outer face (10e) comprising a tread formed by a plurality of grooves(S) recessed with respect to a rolling surface (SR),

an ultrasound emitter (2) and an ultrasound receiver (3),
the device (1) being configured for attaching to the inner face (10i) of the tyre (10), such that, by means of the emission by the emitter (2) of an ultrasound wave through a material of the tyre (10) and the reception by the receiver (3) of said wave after bouncing on the rolling surface (SR), a distance is obtained,
wherein the ultrasound emitter (2) and receiver (3) are respectively configured for emitting and receiving ultrasound at frequencies of between 100 KHz and 500 KHz.
