8.13. Anti-blocking system of brakes of back wheels



Cars with a wheel formula 4x2 or 4x4 are equipped with anti-blocking system of back wheels (RWAL system). The system affects back wheels and is intended for prevention of a drift of the car at sharp braking. The RWAL system provides stability as loaded, and the empty car.

The system regulates pressure in the highway of brakes of back wheels at sharp braking and by that removes their blocking. An executive element of system is pressure regulator which is mounted on the chassis on the right side. The regulator works from the teams arriving from the RWAL system ESM processor module. The processor module is mounted under the passenger's seat. This module should not be confused to the processor block of the ECU engine. On the processor module the signal from the speed sensor on the basis of which the team for pressure regulator is developed arrives. If the team of dumping of pressure arrives, then the reducing valve of the regulator opens and liquid comes to a receiver in which it is supported under pressure. If the team of increase in pressure arrives, then the gate-type valve of the regulator begins to pulse, providing intake of liquid to the main highway. The control lamp on the dashboard informs on work of system. At each inclusion of ignition also the system of self-diagnostics joins. The control lamp of anti-blocking system has to light up and later 2 sec. to go out. If the lamp does not die away, then the anti-blocking system is faulty.
