Arrangement of elements of system of anti-blocking of brakes (ABS)
The system of anti-blocking of brakes (ABS) is intended for preservation of controllability of the car, its stability and maintenance of optimum decrease in speed at sharp braking in the majority of road conditions. It is carried out by tracking speed of rotation of each of wheels and adjustment of pressure of brake liquid for each of wheels. It allows to prevent blocking of wheels.
The drive of ABS system consists of the hydraulic pump and four electromagnetic valves. The pump creates hydraulic pressure in cavities of a drive which creates pressure in brake system. The pump and cavities are in the drive case. Electromagnetic the valve regulate pressure in brake system at ABS system inclusion. One valve is intended for each of wheels.
Sensors of speed of rotation of wheels
Sensors of speed of rotation of wheels which are available on each wheel, generate weak electric impulses at rotation of gear rotors, sending signals of various tension on the ABS electronic control unit, showing speed of rotation of wheels.
The ABS electronic control unit is established under the dashboard and is an ABS system brain. The electronic control unit accepts and processes information received from sensors of speed of rotation of wheels, and supervises pressure in brake system, preventing blocking of wheels. The electronic control unit also constantly watches system work for tracking emergence of malfunctions.
If the alarm bulb on an instrument guard lights up and does not die away at car movement, means, the ABS system demands attention. Though the special electronic tester of diagnostics of ABS is necessary for exact diagnostics of ABS system, the motorist can carry out the following preliminary checks independently before addressing in a repair truck:
If everything is all right, it is necessary to address to experts.
