On models of cars considered in the present Management the independent suspension bracket of hydropneumatic type of exclusive design Citroёn is used.

The basic components of a forward suspension bracket are vertically established hydraulic rack, the bottom levers and a bar of the stabilizer of cross-section stability. The bottom levers and a bar of the stabilizer of cross-section stability are established on a forward stretcher of the car. Giving of a working liquid in hydraulic blocks is carried out from the main hydraulic system of the car through the proof-reader of height of position of the forward suspension bracket, influencing a bar of the stabilizer of the cross-section stability, attached to the bottom levers of a suspension bracket by means of racks.

Longitudinal levers, and also the back hydraulic blocks (racks) supplied with a working liquid from the main system through the proof-reader of height of position of a back suspension bracket are put in a basis of a design of a back suspension bracket.

The height of a road gleam of the car can change by switching of the car of a control lever established in salon. The lever by means of executive rods is connected to proof-readers of height of a forward and back suspension bracket. On models of early years of release at deenergizing of the engine the car falls to the bottom position. Later models are equipped by the unilateral valve isolating a suspension bracket from the main hydraulic system that allows to avoid similar lowering of a body after останова the engine.

Hydraulic blocks are equipped automatic демпферами, replacing screw springs and the assemblages of shock-absorbers used in suspension brackets of usual type.

Some of models of a representation class are equipped by the special "hydroactive" suspension bracket allowing the driver to choose one of two modes of installation of a suspension bracket ("Normal" or "Sports"). The system has electronic control on the basis of signals established on elements of a suspension bracket of information gauges. "Normal" installation provides the maximum comfort at car movement, automatically adapting a suspension bracket for a manner of driving of the driver and a condition of a road covering. At a choice of the "Sports" mode the suspension bracket becomes more rigid that approaches for a sports manner of driving and at movement on a streamer more. The function chart of a hydroactive suspension bracket is resulted on an illustration the Function chart of a hydroactive suspension bracket.

The steering mechanism реечного type is established on the cross-section beam attached to a stretcher. Steering рейка it is equipped карданным by the hinge and flexible муфтой. Some of models are equipped by system of hydrostrengthening of a wheel the working liquid in which moves from a path of the main hydraulic system of the car (see the Head the Uniform hydraulic system).
