DEVICE FOR ATTACHMENT TO A WHEEL AND WHEEL WITH SUCH A DEVICE
First Claim
1. A vehicle wheel of a motor vehicle to which is attached a device, the wheel comprising a rim, a wheel bearing, and a plurality of lugs threadably engaged with threaded bolts so that the lugs are located on an outwardly facing side of the rim, and the device comprising a support mounted to the wheel of the motor vehicle, means provided on said support for detecting vibrations which occur during driving of the motor vehicle and for evaluating the vibrations for an incipient fault state of the wheel bearing, and a visual indicator outside the vehicle which provides a visible signal of the incipient fault state when the evaluation indicates the incipient fault state, the device being mounted on the outwardly facing side of the rim.

Abstract
A device for attachment to a motor vehicle wheel includes an arrangement which, during movement or driving of the motor vehicle, detects vibrations which occur, evaluates the vibrations for an incipient fault state of a wheel bearing of the vehicle wheel, and delivers a signal when the monitoring or evaluation yields or indicates the incipient fault state.

- 1. A vehicle wheel of a motor vehicle to which is attached a device, the wheel comprising a rim, a wheel bearing, and a plurality of lugs threadably engaged with threaded bolts so that the lugs are located on an outwardly facing side of the rim, and the device comprising a support mounted to the wheel of the motor vehicle, means provided on said support for detecting vibrations which occur during driving of the motor vehicle and for evaluating the vibrations for an incipient fault state of the wheel bearing, and a visual indicator outside the vehicle which provides a visible signal of the incipient fault state when the evaluation indicates the incipient fault state, the device being mounted on the outwardly facing side of the rim.
- 8. A device adapted to be attached to a wheel of a motor vehicle which comprises a wheel bearing having a greased roller bearing, the device comprising a support adapted to be mounted to the outwardly facing side of a rim of the wheel, means provided on said support for detecting vibrations which occur during driving of the motor vehicle and for evaluating the vibrations for an incipient fault state of the greased roller bearing, and a visual indicator directly on the support which provides a visual signal of the incipient fault state when the evaluation indicates the incipient fault state.
