WHEEL FIXING MEMBER LOOSENING DETECTION DEVICE AND WHEEL FIXING MEMBER LOOSENING DETECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/007716
Kind Code:
A1
Abstract:
A wheel fixing member loosening detection device (31) detects loosening of a wheel fixing member (14) which fixes a wheel (13) to an axle (11). The wheel fixing member loosening detection device (31) comprises: a reception antenna (37) which is arranged on the wheel (13) so as to be able to rotate integrally with the wheel (13); and a control device (32). The reception antenna (37) receives a wireless signal transmitted from a transmission antenna (27) mounted to the wheel fixing member (14). The control device (32) detects the loosening of the wheel fixing member (14) on the basis of a change in signal intensity of the wireless signal received by the reception antenna (37) caused by a change in the positional relationship between the transmission antenna (27) and the reception antenna (37).
