Abstract

Device for preventing, under critical braking conditions, the blocking of one or more preset wheels of a vehicle provided with a hydraulic braking system including a master cylinder and, for each wheel, a brake provided with a hydraulic actuator for control connected to the master cylinder; said device comprising a first switching solenoid valve intended to be interposed between the master cylinder of the hydraulic actuator of said at least one predetermined wheel and intended, when it receives a control signal, to pass from a first state, in which it connects the master cylinder to said hydraulic actuator to allow the braking of said preset wheel, to a second state in which it interrupts the connection between the master cylinder and said hydraulic actuator and allows communication between said hydraulic actuator and allows communication between said hydraulic actuator and the discharge to said hydraulic actuator. Through a unidirectional valve tared to reduce the braking of at least said predetermined wheel, and control and command means arranged to supply a control signal to said solenoid valve when, during the braking phase, the deceleration of at least one reference wheel of the vehicle exceeds a first predetermined value, characterized by the ho that also comprises a second switching solenoid valve interposed between said first solenoid valve and the hydraulic actuator of said at least one predetermined wheel, and intended to pass, when receiving a switching signal, from a first state, in which it allows the connection of said hydraulic actuator to the master cylinder through said solenoid valve to allow the braking of said predetermined wheel, to a second state in which it prevents said connection and puts in communication said hydraulic actuator with the discharge, and because said control means of control they are intended to supply the switching signals to said second solenoid valve when, during the braking phase, the deceleration of a predetermined wheel of the vehicle exceeds a second value greater than said first predetermined value.
