Arrangement of units of ABS system
On cars the system of an automatic unblocking of brakes (ABS - system) intended for increase of stability of the car in the conditions of sharp braking is installed. Pressure in a contour of brakes is regulated depending on the speed of rotation of wheels registered by sensors.
It is mounted with on the right mudguard. On the block signals from the switch of a signal of braking and sensors of speed of each wheel on the basis of which pressure in a hydraulic actuator of this wheel is regulated arrive. If the speed of rotation of a wheel differs from basic, the control unit opens the electromagnetic valve of an aktyuator and liquid under excessive pressure flows down in the tank. The wheel rastormazhivatsya partially. After alignment of speed of rotation the valve is closed and pressure again increases. Numerous repetition of such cycles stabilizes the speed of rotation of all wheels and increases stability of the car. The control unit also possesses self-diagnostics function.
Consists of system of the solenoidal valves working from control unit signals.
Sensors of induction type, are mounted on each of wheels. Sinusoidal signals from the sensor arrive on the control unit.
Provides inclusion of back lamps and gets ready the control unit when braking.
