8.13. Antiblocking system of brakes of back wheels


Cars with the wheel formula 4х2 or 4х4 are equipped by antiblocking system of back wheels (RWAL-system). The system operates on back wheels and is intended for prevention of drift of the car at sharp braking. The RWAL-system provides stability both loaded, and the empty car.

The system regulates pressure in a highway of brakes of back wheels at sharp braking and by that removes their blocking. An executive element of system is the regulator of pressure which is mounted on the chassis on the right side. The regulator works from the commands arriving from processor module ESM of RWAL-system. The processor module is mounted under a seat of the passenger. This module should not be confused to the processor block of engine ECU. On the processor module the signal from the gauge of speed on which basis the command for a pressure regulator is developed arrives. If the command of dump of pressure opens редукционный the valve of a regulator and a liquid arrives arrives in a receiver in which it is supported under pressure. If the command of increase of pressure starts to pulse отсечной the regulator valve arrives, providing liquid receipt in the basic highway. The control lamp informs on system work on the panel of devices. At each inclusion of ignition the self-diagnostics system joins also. The control lamp of antiblocking system should light up and later 2 сек goes out. If the lamp does not die away, the antiblocking system is faulty.
