General information and precautionary measures General information
The active suspension bracket, the brake system and, at the corresponding complete set, system of hydrostrengthening of a wheel on the cars considered in the present manual are united in uniform hydraulic system. The scheme of an arrangement of components of hydraulic system is given in the illustration Scheme of an Arrangement of Components of Hydraulic System on lobby stretchers (the top illustration) and back (the lower illustration) suspension brackets. The liquid used as a working body from the special hydraulic tank installed in a motive compartment of the car under a pressure moves in pressure regulator. Pressure in system is forced by means of the hydraulic pump which drive is carried out from a pulley of a bent shaft by means of the belt drive. From pressure regulator liquid moves the safety valve, connected to the valve of management of the hydrocompensator, and comes further to blocks of proofreaders of height of a road gleam of forward and back suspension brackets of the car. From assemblies of proofreaders liquid comes to cylinders of hydraulic blocks of a suspension bracket from where under low pressure comes back in the tank. Height of a road gleam is chosen the driver manually and is supported due to continuous supply of liquid in working cylinders of proofreaders of a suspension bracket or branch her from these cylinders according to movement of forward and back stabilizers of cross stability to which these cylinders are connected. Transfer of hydraulic pressure to independent forward and back contours of the brake system is carried out from the valve of management of the hydrocompensator. And in a forward contour liquid is forced directly via the valve of management whereas the back contour works contact with 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 the effort developed by brake mechanisms of back wheels varies depending on extent of loading of the car - the stronger 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 high pressure and the block of the regulator the distributor of a hydraulic stream is placed. A problem of the distributor is distribution of a pressure 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 switching off of the engine; the car at the same time falls to extreme lower situation. Later models are equipped with the locking valve isolating a suspension bracket from the main hydraulic path. Implementation of any procedures of service of the components of hydraulic system which are not included in composition of material of the present Chapter (or Heads the Brake system and the Running gear and steering), has to be entrusted to specialists of company car repair shop of the Citroyon company. Precautionary measures
In extreme situations use as a working body in hydraulic system of the SAE 10 or SAE 20 engine oil is allowed, however in such cases on arrival to the place of the repair/parking the hydraulic path has to be emptied and at the first opportunity is filled with standard LHM liquid. After removal from system of liquid of a doubtful origin the hydraulic path has to be washed out by special structure which it is possible to acquire in company service centers of the Citroyon company. Having pumped over system, leave its filled with flushing structure which has to be used throughout about 1000 km (600 miles) of a run. Then the system should be emptied and filled with standard hydraulic LHM liquid again. In case of failure of rubber consolidations as a result of use of non-standard liquid, all damaged components are subject to replacement. Performance of this work should be charged to specialists of car repair shop. As replaceable components it is necessary to use only company details of production of the Citroyon company which are usually painted in white or green color and are intended for use in contact with LHM liquid. One of the basic rules which have to be observed at service of components of a hydraulic path is the most careful respect for purity. Carefully wipe the components and surfaces adjoining to them which are subject to a detachment. All connections at once cork the removals of a component opened later in order to avoid hit in system of dirt and foreign objects. For rubbing of components use only gasoline. Before performance of any works on service of components of hydraulic system pressure in a path has to be dumped. After dropping pressure in system it is necessary to disconnect a negative wire from the battery. |
