18.104.22.168.5. Antiblocking system
Sliding minimum (0 %) when the wheel slides freely, and maximum (100 %) when the wheel is blocked. Peak efficiency of braking is reached, when sliding makes 15 %. This size also allows to keep stability and controllability of the car.
The role of antiblocking system consists in restriction of the pressure created in hydraulic system of brakes so that the sliding size was kept about optimum size (15 %). Action of this system should be immediate and separate for each wheel. The system should answer immediately each change of a surface (coupling factor) and loading on the car.
Four gauges (at each wheel of the car) transmit the signals informing on speed of rotation of each wheel of the car in the electronic actuation device.
The electronic actuation device located on the right side under the forward panel, on the basis of the received information on unequal speed of rotation of separate wheels (or about them заблокировании) transfers a command of reduction of force of braking in hydraulic knot of management (the pressure submitted to a support of a brake) of a wheel, which beginning to test excessive sliding. The electronic actuation device carries out also autodiagnostic function, warning the driver fire of a control bulb about registration of malfunction of electric chains or elements of antiblocking system. At faulty system ABS of a brake nevertheless are serviceable and function as if this system is not present in the car. It is unique a control bulb warns the driver that system ABS does not correct its errors.
The hydraulic knot of management contains the main brake cylinder of type a tandem which operates forward brakes, and the hydraulic auxiliary device which operates back brakes. The hydraulic auxiliary device contains six electromagnetic valves, operated the electronic actuation device, regulating pressure in brakes of separate wheels, and consequently also force of braking. Three inlet electromagnetic valves during normal braking (without sliding) remain opened, and three final valves – closed. They are located in contours of the right forward brake, the left forward brake and back brakes.
Such cycle of braking and free rotation of a wheel occurs very quickly (some times in a second) and proceeds to a stop cars or to release brake pedals.
The antiblocking system (ABS) operates at speed of movement more than 7 km/h.
