ABSTRACT:
A device for eliminating the locking risk of vehicle wheels at the application of a braking force, comprises an accelerometer mounted on a non-rotary portion connected with the wheel axle for emitting continuously, in response to the motions of the mounting point due to irregularities of the road, a primary signal indicative of the acceleration of the point as influenced by the damping properties of the wheel tire; an electronic unit for transforming the primary signal to a secondary signal, the strength of which is related to the speed of changes in the primary signal, and a control device connected to the electronic unit and controlling the braking force of a fluid-operated brake system so as to momentarily reduce the braking force in response to a sudden change in the secondary signal, corresponding to a sudden reduction in the ground braking moment of the wheel and due to reduced damping of the tire, whereby the locking risk is removed.
