General information and precautionary measures General information
The active suspension bracket, brake system and, at the corresponding complete set, system of hydrostrengthening of a wheel on cars considered in the real Management are incorporated in uniform hydraulic system. The scheme of an arrangement of components of hydraulic system is provided on an illustration the Scheme of an arrangement of components of hydraulic system on lobby stretchers (the top illustration) and back (the bottom illustration) suspension brackets. Liquid used as a working body from the special hydraulic tank established in an impellent compartment of the car, under a pressure moves in a pressure regulator. Pressure in system is forced by means of the hydraulic pump which drive is carried out from a pulley of a cranked shaft by means of a belt drive. From a pressure regulator liquid moves the safety valve, connected to the valve of management of the hydrojack, and arrives further in blocks of proof-readers of height of a road gleam of forward and back suspension brackets of the car. From assemblies of proof-readers liquid arrives in cylinders of hydraulic blocks of a suspension bracket, from where under low pressure comes back back to the tank. The height of a road gleam gets out the driver manually and is supported at the expense of continuous supply of liquid in working cylinders of proof-readers of a suspension bracket or branch it from these cylinders according to moving of forward and back stabilizers of cross-section stability to which these cylinders are connected. Transfer of hydraulic pressure to independent forward and back contours of brake system is carried out from the valve of management of the hydrojack. And in a forward contour liquid is forced directly via the management valve whereas the back contour works contact to a hydraulic path of a back suspension bracket. At such scheme of distribution of hydraulic pressure the main brake effort is put to forward wheels of the car whereas developed by brake mechanisms of back wheels the effort varies depending on extent of loading of the car - the more strongly the car is loaded, the pressure in a hydraulic contour of a back suspension bracket and, respectively, in a brake contour is higher. On the models equipped with system of hydrostrengthening of a wheel, between the pump of a high pressure and the block of a regulator the distributor of a hydraulic stream is placed. A problem of the distributor is pressure distribution between a contour of the power steering and hydraulic paths of suspension brackets. On models of early years of release pressure in a path of an active suspension bracket is dumped at engine switching off; the car thus falls to extreme bottom situation. Later models are equipped with the locking valve isolating a suspension bracket from the main hydraulic path. Performance of any procedures of service of components of the hydraulic system which has not been included in structure of a material of the present Chapter (or Heads Brake system both the Running gear and a steering), should be entrusted to specialists of firm car repair shop of the Citroёn company. Precautionary measures
In extreme situations use as a working body in hydraulic system of SAE 10 or SAE 20 engine oil is allowed, however in such cases on arrival to a repair/parking place the hydraulic path should be emptied and at the first possibility is filled with standard LHM liquid. After removal from system of liquid of a doubtful origin the hydraulic path should be washed out by special structure which it is possible to get in firm Citroёn company service centers. Having pumped over system, leave its filled with flushing structure which should be used throughout about 1000 km (600 miles) run. Then it is necessary to empty and fill system with standard hydraulic LHM liquid again. In case of failure of rubber consolidations as a result of use of the non-standard liquid, all damaged components are subject to replacement. It is necessary to charge performance of this work to specialists of car repair shop. As replaceable components it is necessary to use only firm details of production of the Citroёn company which are usually painted in white or green color and are intended for use in contact to LHM liquid. One of the basic rules which should be observed at service of components of a hydraulic path, the most careful observance of purity is. Carefully wipe components subject to a detachment and surfaces adjoining to them. All opened after removal of a component of connection at once cork in order to avoid hit in system of dirt and extraneous subjects. For rubbing of components use only gasoline. Before performance of any works on service of components of hydraulic system pressure in a path should be dumped. After a pressure sbrasyvaniye in system it is necessary to disconnect a negative wire from the battery. |
