The system of stabilization of the situation of a body automatically provides constancy of size of a road gleam (clearance) at change of load of a back axis.

Fig. 1.45. System of stabilization of the situation of a body: 1 – pneumatic shock-absorber; 2 – control unit of system; 3 – a beam of the back bridge with the stabilizer of cross stability; 4 – compressor; 5 – stabilization block

On the cars equipped with this system (fig. 1.45) instead of traditional hydraulic shock-absorbers are established pneumatic 1. In them compressed air from the electric compressor 2 of the piston type located in left moves we will touch to a corner of the luggage compartment. The minimum pressure of air in system – 5 atm.

Fig. 1.46. Control unit of system of stabilization of the situation of a body and compressor: 1 – control unit; 2 – valve

The control unit 1 (fig. 1.46) of system of stabilization of the situation of a body is installed together with the compressor 2. The choice of an operating mode of system is carried out by the switch 3 on the control unit 1.

Provisions of the switch of 3 operating modes of system:

1 – the system is included (the manual mode of installation of clearance);

2 – the system is switched off;

3 – reduction of normal clearance by 100 mm (automatic operating mode of system);

4 – normal clearance (automatic operating mode of system);

5 – increase in normal clearance by 100 mm (automatic operating mode of system).

The manual mode of installation of clearance (situation 1 and 2) is chosen only in case of malfunction of system. At the automatic mode (situation 3-5) the chosen size of clearance of the car is always supported by a constant.

The switch has to be in situation 4 constantly. Provisions 3 and 5 choose only in extreme cases at operation of the car with the trailer.
