The antiblocking system of brakes is intended for an exception of blocking of wheels at intensive braking.
Main functions ABS:
– Reduction of a brake way at the expense of an exception of blocking of wheels at intensive braking;
– Improvement of stability of a driving in the course of braking.
The antiblocking system of brakes works on the basis of the information from four gauges, transferred to block ABS. The system operates each wheel separately and reduces pressure of a liquid in that wheel brake mechanism which wheel starts to be blocked.
Under normal conditions the standard brake system carries out braking till the moment of blocking of the wheel which are found out by the block of management ABS. During usual braking inlet valves usually open, and final valves are usually closed.
When the block of management ABS finds out wheel blocking, it operates each valve for increase or pressure reduction.
The block of management ABS defines frequency of rotation and norm of delay of each wheel on the basis of the information from gauges of frequency of rotation of a wheel. At braking frequency of rotation of a wheel decreases also block ABS defines a difference between speed of the car and frequency of rotation of a wheel. If delay of some wheels exceeds expected value, block ABS defines the beginning of blocking and opens corresponding electromagnetic valves to reduce pressure of a brake liquid. Thus frequency of rotation of a wheel increases also the electromagnetic valve of dump of pressure is closed and there is an increase in pressure of a brake liquid in the working brake cylinder of a corresponding wheel.
