DEVICE AND METHOD FOR TESTING A TYRE BY MEANS OF AN INTERFEROMETRIC, IN PARTICULAR SHEAROGRAPHIC, MEASURING METHOD

摘要

A device for testing a tyre (30), which has a tread (37), a first sidewall (31), which has a first bead (32) and is connected to the tread (37), a second sidewall (34), which has a second bead (35) and is connected to the tread (37), and a rolling axis (R), by means of an interferometric, in particular shearographic, measuring method, comprises a pressure chamber (20), in which the tyre (30) can be positioned and can be exposed to a predetermined pressure (P), at least one measuring head (101, 102, 103, 104, 105, 106) for optically scanning and testing the tyre (30) and a supporting device (200) for receiving and supporting the tyre (30) at the first bead (32) and/or at the second bead (35).
