The hydraulic block
It is located in a motor compartment at the left behind: the hydraulic block is between the brake pipeline from the main brake cylinder and the brake pipeline to wheel brakes. According to commands of the electronic block of management pressure in brake system is supported to constants, decreases or created again. However this pressure cannot be above that is created in the main brake cylinder after pressing of a pedal of a brake by the driver. Pressure regulation is carried out by four quickly включающимимся valves with an electromagnetic drive – on one on a wheel.
Gauges of frequency of rotation
Frequency of rotation of each separate wheel the gauge of frequency of rotation (defines all their four pieces) and hands over this information to the management block. From its part the management block gives a command to the hydraulic block.
The electronic block of management
The management block is located at the left under back sitting and processes arriving signals from gauges of frequency of rotation. Simultaneously it operates the hydraulic block so that wheels were not blocked. Along with difficult processing of signals and the logic following this element the management block contains also the blocking scheme. With its help the device can check itself, distinguish external errors and supervise working pressure. If malfunctions are established, АБС is disconnected, on the instrument panel the control bulb lights up.
Three relays participate in work АБС:
The main switch
The models which have been let out till 07.92
By means of the main switch located on the panel of switches on the instrument panel at cars, 92 let out till July, it is possible to disconnect АБС that in extreme road conditions it was possible to reach some reduction of a brake way. So, for example, if on road it is scattered щебенка or ice is covered by snow, at braking in front of tyres
