Abstract

A wheel bearing unit that measures the contact forces between the tire and the road under all driving situations including operation of the brake, and provides information for the vehicle operation control systems and for optimizing the braking process, the unit including first sensors arranged on the stationary part of the wheel bearing in order to measure the forces acting in the wheel bearing, and second sensors arranged on a support members for the disk-brake caliper for continuously determining the acting braking forces.
