Abstract
To provide a wheel support bearing assembly having a capability of detecting the number of revolutions of a wheel, having no risk of breaking of wire outside a vehicle body, capable of reducing the weight and cost of an automotive vehicle. This wheel support bearing assembly for rotatably supporting a wheel 13 relative to a vehicle body structure 12 includes an outer member 1 having its inner periphery formed with plural rows of raceways 6 and 7, an inner member 2 having raceways 8 and 9 confronting respectively to the raceways 6 and 7, and rows of rolling elements 3 accommodated respectively between the raceways. An electric generator 4 for generating an electric power as one of the outer and inner members 1 and 2 rotates relative to the other of the outer and inner members 1 and 2. A signal indicative of the number of revolutions of the wheel 13 outputted from the electric generator 4 is transmitted wireless by mean of a wireless transmitting means 5A.
