Forward suspension bracket completely independent with a stretcher and the bottom operating levers, racks of MakFersona and the stabilizer of cross-section stability (the Design of a forward suspension bracket see an illustration). Racks consist from газонаполненных telescopic shock-absorbers and screw springs and fasten the top ends to the strengthened support on mudguards of forward wings, and bottom to assemblages of rotary fists. Naves are equipped by noncontrollable bearings. The bottom parts of rotary fists by means of spherical support are connected to the bottom levers of a suspension bracket. Spherical support fasten to levers bolts, and to rotary fists — with the help сболчиваемых collars. The internal ends levers fasten to a stretcher by means of резинометаллических hinges, limiting lateral and longitudinal moving of forward wheels. The stabilizer of cross-section stability enters into a standard complete set of all models. The stabilizer is fixed on a stretcher and connected to racks of a suspension bracket by means of two vertical draughts (racks).

The torsionnaja beam of a semiindependent back suspension bracket consists of two longitudinal levers and a connector (the Design of a back suspension bracket see an illustration). In a back part of levers of a suspension bracket are equipped landing under fastening of shock-absorbers and spring assemblages, and also vertical flanges to which by bolts fasten ступичные assemblages of back wheels together with boards of brake mechanisms. On the forward ends of levers plugs with запрессованными in them резинометаллическими hinges are equipped. Through hinges the bolts fixing levers of a suspension bracket in приболчиваемых to longerons of a body arms are passed. The top ends of shock-absorbers fasten to bearing elements of the bottom of a body. Springs are established separately from shock-absorbers and fixed by two saddles one of which fastens to a flange on the lever, another — to the car bottom. Wheel bearings are built in in not folding ступичные assemblages. Models the Versatile person are equipped by system of manual adjustment of height of a back road gleam. The system copes by giving in shock-absorbers of compressed air. The gleam size depends on pressure in shock-absorbers which is regulated by means of the valve located in a luggage space.

The steering mechanism — ordinary реечного type, with ударопоглощающей a steering column (the Design of a steering drive see an illustration). The column is connected to the mechanism by means of equipped крестовинами an intermediate shaft. The sliding top section of a steering column is equipped by the lock blocking a steering drive. In a closed condition the lock allows a steering column to rotate with effort in 200 Nanometers that prevents possibility of destruction of a lock pin. Thus the size of the moment demanded for rotation a steering wheel, does impossible driving. The steering mechanism is established on a forward stretcher of a suspension bracket. Steering draughts fasten to levers of rotary fists by means of steering tips. The standard complete set of all models includes system of hydrostrengthening of a steering drive (ГУР). The electrohydraulic steering pump is established directly on the steering mechanism and does not demand service. The tank of a hydraulic liquid is built in pump assemblage.

Often in the course of service of components of a suspension bracket it is necessary to face with resistant отдаванию fixture. Прикипание fixture elements it is connected by that they are constantly subject to external influences, are in contact to water, a dirt, a soot and other promoting development of corrosion by substances. For the purpose of simplification of procedure отдавания its such"become attached"fixture it is necessary to impregnate with plentiful quantity of getting oil beforehand. Зачистка open carving parts of fixture a rigid wire brush also promotes simplification отдавания приржавевших nuts. Sometimes, in especially hard cases, for отпускания "the become attached" bolt / of a nut it is possible to take advantage выколоткой. Выколотка rests against edge шлица nuts / of a head of a bolt, then sharp blows by a hammer are struck to its opposite end. Watch that выколотка has broken, try to damage inexact blows a carving. Effective enough way is also warming up resistant отдаванию fixture and a surface of a component surrounding it a torch of a blowtorch or a gas torch though composers of the given Management and do not recommend to resort without extreme need to such technology in view of its potential danger connected with possibility of ignition and risk of reception of burns. Any extension pieces, collars and trumpet nozzles are intended for twisting moment increase at отпускании fixture on them. However, remember that it is not necessary to use such intensifying adaptations complete with the drive equipped with "rattle" — the risk of failure of the ratchet mechanism is too great. Sometimes the nut / a bolt starts to give in after preliminary will be slightly tightened clockwise. All fixture, отпускание which has demanded application of not ordinary measures at assemblage is subject to replacement!

After отдавания attentively check a condition of fixture and in case of need make its replacement with elements of the same standard size. At assemblage tighten fixture of components of a suspension bracket and a steering it is strict with demanded effort.


At all do not undertake attempts рихтовки the deformed components of a suspension bracket and a steering — replace defective details new!

As procedures of service of components of a suspension bracket are carried out under the car, it is necessary to take care in advance of possibilities of lifting of a vehicle and its fixing in the lifted position (prepare reliable a jack and props).

At all do not perform any works under the car, fixed in the lifted position only by means of a jack!

Safety measures

In ступичную the steering wheel part is built in a safety pillow. For a guarantee of serviceability of operation of a pillow at emergency collisions, and also in order to avoid risk of reception of traumas as a result of its casual activation it is necessary to observe certain safety measures (the Onboard electric equipment see also the Head):

  1. Before the beginning of works with a safety pillow, or near to a route of a lining of electroconducting SRS necessarily disconnect a negative wire of the battery, to start performance of works follows after not less than one minute after a battery detachment, — time is necessary on a discharge of the condenser of the reserve power supply.
  2. Do not suppose a warming up of the module of a pillow of safety from above 90С. Do not overturn the removed module of a pillow of safety an overlay downwards.
  3. Do not suppose hit on a surface of the module of solvents and washing-up liquids, — for steering wheel wiping use only the pure, slightly humidified rags.
  4. The block of management SRS and modules of pillows of safety are sensitive to the directed overloads (blows) and after falling from height more than 50 sm are subject to replacement.
  5. Before carrying out of welding works on the car without fail disconnect electroconducting of the block of management SRS.
  6. On the models equipped with passenger pillows of safety in order to avoid reception of traumas do not establish any additional equipment and do not place any extraneous subjects in a zone of operation of pillows.
