ABSTRACT:
Action force of a wheel is measured in order to measure the road surface frictional force, vertical drag, road surface friction coefficient, etc. Means for making these measurements can be constituents of an antilock brake system, traction control system, etc. These constituents may also serve as devices for measuring stresses generated in other structures. In a specific example, axle of a vehicle is formed with a hole, a stress detection sensor is installed in the hole and secured in position with the aid of a spacer element, and a detection signal from the stress detection sensor is processed in a signal processing circuit.
