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 reduction of speed at sharp braking in the majority of road conditions. It is carried out by tracking the speed of rotation of each of wheels and adjustment of pressure of brake fluid for each of wheels. It allows to prevent blocking of wheels.
ELEMENTS OF SYSTEM
The drive of system of ABS consists of the hydraulic pump and four electromagnetic valves. The pump creates hydraulic pressure in drive cavities which creates pressure in brake system. The pump and cavities are in the drive case. Electromagnetic the valve regulate pressure in brake system at inclusion of system of ABS. 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 to the ABS electronic control unit, showing the speed of rotation of wheels.
The ABS electronic control unit is installed under the dashboard and is a brain of system of ABS. The electronic control unit accepts and processes information received from sensors of speed of rotation of wheels and controls pressure in brake system, preventing blocking of wheels. The electronic control unit also constantly watches work of system for tracking emergence of malfunctions.
If the alarm bulb on an instrument guard lights up and does not die away at the movement of the car, so the system of ABS demands attention. Though the special electronic tester of diagnostics of ABS is necessary for exact diagnostics of system of ABS, the motorist can carry out the following preliminary inspections independently before addressing to auto repair shop:
If everything is all right, it is necessary to address to experts.
