STABILITY CONTROL APPARATUS AND LOAD MESURING INSTRUMENT FOR WHEEL SUPPORTING ROLLING BEARING UNIT

摘要

A stability control apparatus, includes: a grip detector that changes an output based on a grip force applied in a direction hindering a slippage of a wheel, acting on a contact face between the wheel supported by a wheel supporting rolling bearing unit and the road surface, the wheel supporting rolling bearing unit for supporting freely rotatably the wheel to a vehicle body; and a controller that performs a control for keeping a running stability of the vehicle in response to an input of a detection signal of the grip detector. Furthermore, a stability control apparatus having a rolling bearing unit having a load measuring unit suppresses the contraction of components of a suspension device to restrain the vehicule body from being inclined with respect to the road surface. The load is calculated based on a detection signal sent from a pair of revolving speed detection sensors.
