Abstract
According to one embodiment of the present disclosure, there is provided a failure diagnosis device used for diagnosing the presence of failure or abnormal operation of a wheel bearing. The failure diagnosis device according to one embodiment of the present disclosure may comprise a housing; a magnetic coupling part provided in the housing; and a sensing part provided in the housing and configured to detect physical characteristic related to an operational state of a vehicle. According to one embodiment of the present disclosure, the sensing part may comprise an acceleration sensor configured to collect acceleration information, and the failure diagnosis device may be configured to be detachably mounted to one side of a wheel by virtue of a magnetic force generated by the magnetic coupling part.
