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

Fig. 1.45. System of stabilization of provision of a body: 1–pneumatic shock-absorber; 2–control unit system; 3–a beam of the back bridge with the stabilizer of cross-section 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 the compressed air from the electric compressor 2 of the piston type located in the left moves we will touch to a corner of a luggage compartment. The minimum pressure of air in system – 5 atm.

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

The control unit 1 (fig. 1.46) is established by system of stabilization of provision of a body 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.

Positions of the switch of 3 working hours of system:

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

2–the system is switched off;

3–reduction of a normal road clearance by 100 mm (automatic working hours of system);

4–normal road clearance (automatic working hours of system);

5–increase in a normal road clearance at 100 mm (automatic working hours of system).

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

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