Arrangement of units of ABS system
On cars the system of an automatic unblocking of brakes (is established to ABS - system), intended for increase of stability of the car in the conditions of sharp braking. Pressure in a contour of brakes is regulated depending on speed of rotation of the 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 speed of rotation of a wheel differs from base, the control unit opens the electromagnetic valve of an aktyuator and liquid under superfluous pressure flows down in the tank. Wheel partially растормаживается. After alignment of speed of rotation the valve is closed and pressure again accrues. Numerous repetition of such cycles stabilizes 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 signals of the control unit.
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 sets ready the control unit when braking.
