8.2.1. ABS system units


Arrangement of units of the ABS system

1. Back sensors of speed
2, 5. Rotors of sensors of speed
3. Braking signal switch
4. Control unit
6. Forward sensors of speed
7. Aktyuator
8. Relay
9. Delay sensor


The main cylinder, the electrohydraulic pump and 4 solenoidal valves are a part of an aktyuator.

The pump is intended for pumping of liquid in aktyuator receivers through which pressure in a contour of brakes moves.

Valves operate pressure in a contour of brakes at operation of the ABS system, it is the share of a wheel on 1 valve.

Sensors of speed of rotation of wheels

Sensors of rotor type, are mounted on each of wheels. Signals from sensors arrive on the control unit.

Forward sensors are mounted on a rotary fist, near gear rings of rotors. Rotors are structurally combined with forward half shafts.

Back sensors are mounted on a bridge beam, rotors are a part of a back nave.

ABS system control unit

The control unit is mounted under a forward partition of a body. 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. The control unit also possesses function of self-diagnostics and storing of refusals.

At system failure the control lamp on the dashboard lights up, and in memory the code of refusal which can be considered and defined the nature of malfunction is brought.
