A wheel support bearing assembly for rotatably supporting a wheel 13 relative to a vehicle body structure 12 includes outer and inner members 1 and 2 with dual rows of rolling elements 3 interposed therebetween. An electric generator 4 for generating an el...

Provided is rotational-state-of-wheel detecting apparatus that can avoid output of an incorrect rotational direction during a halt of a wheel. In an electronic control unit ECU (10), a signal input section (10a) accurately detects wheel speeds and rotation...

In a vehicle wheel rotation detecting system, a signal input portion (10a) of an ECU accurately detects a vehicle wheel speed and a rotating direction of the vehicle wheel speed of the respective wheels (12, 14, 16, 18). On the basis of the detected result...

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 suppo...

The invention relates to a device for detecting the instantaneous rotational state, specifically the speed of a vehicle wheel, as well as to a wheel brake arrangement and a method for controlling the wheel brake torque. Furthermore, the invention also rela...
