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

The main 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. Supply of working liquid in hydraulic blocks is carried out from the main hydraulic system of the car through the proof-reader of height of provision 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 by working liquid from the main system through the proof-reader of height of provision 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 is connected by means of executive rods to proof-readers of height of a lobby and a back suspension bracket. On models of early years of release at engine switching off the car falls to the bottom situation. Later models are equipped with 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 with the automatic dampers replacing screw springs and assemblies of shock-absorbers, used in suspension brackets of usual type.

Some of models of a representation class are equipped with 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 sensors. "Normal" installation provides the maximum comfort at car movement, automatically adapting a suspension bracket for a manner of driving of the driver and a paving condition. At a choice of the "Sports" mode the suspension bracket becomes more rigid that is suitable for a sports manner of driving and at movement on a serpentine more. The function chart of a hydroactive suspension bracket is given in an illustration the Function chart of a hydroactive suspension bracket.

The steering mechanism of reechny type is established on the cross-section beam attached to a stretcher. The steering rack is equipped with the kardanny hinge and the flexible coupling. Some of models are equipped with system of hydrostrengthening of a wheel working liquid in which moves from a path of the main hydraulic system of the car (see. Head Uniform hydraulic system).
