Patent ID: 8511902

Claim:
A wheel bearing device for a motor vehicle, comprising: an inner ring arrangement, which is formed for rotationally fixed reception of a first rotary partner; an outer ring arrangement, which is connectable with a second rotary partner in a rotationally fixed manner; a multitude of rolling elements, which roll between the inner ring arrangement and the outer ring arrangement so that the inner ring arrangement and the outer ring arrangement and/or the first rotary partner and the second rotary partner are rotatable against each other; and an electric sensor device, which, using a mechanical contact for detecting a working condition of the wheel bearing device, comprises at least two sensor elements, a stationary sensor element and a rotating sensor element which together form the mechanical contact, wherein the stationary sensor element is connected with the inner ring arrangement without interposition of the first rotary partner, wherein at least one of the sensor elements is temperature-sensitive, so that in case of a temperature increase over a certain operating temperature, a safety distance between the sensor elements is reduced and/or the two sensor elements make mechanical contact.
