10. A suspension bracket and a steering

The basis of a design of a forward suspension bracket is made by the racks of MakFersona passed through screw springs. The top ends of a rack enter into the basic bearings fixed on ledges of mudguards in an impellent compartment of the car. The bottom ends of racks fasten to rotary fists. Besides racks the forward suspension bracket is formed by the bottom operating levers which external ends by means of spherical support are fixed in assemblages of rotary fists, internal axial bolts (the forward ends) and collars of axial plugs (the back ends) fasten to the car bottom. Besides, the structure of a forward suspension bracket includes the stabilizer of cross-section stability.

Back suspension bracket

The back suspension bracket is completely organised by means of the rigid not cutting bridge, four levers (two top and two bottom), a cross-section jet bar and the stabilizer of cross-section stability. Racks are generated by double-thread telescopic shock-absorbers of the cylindrical form and separately established screw springs.

Features of service of components of a suspension bracket and steering

Often in the course of service of components of a suspension bracket and a steering drive 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 release "the become attached" bolt / of a nut it is possible to take advantage выколоткой. Выколотка rests against edge шлица bolt nuts/heads, 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 release 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 become attached" fixture starts to give in after preliminary slightly will be 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 elements of 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!
