10. Suspension bracket and steering The basis of a design of a forward suspension bracket is made by the racks of MacPherson 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 means of spherical support are fixed in assemblies 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 organized 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 created by double-thread telescopic shock-absorbers of a cylindrical form and separately established screw springs.

Steering
All models are equipped with the hydrostrengthened steering mechanism of reechny type connected to rotary fists by means of two cross-section steering drafts. The design of a steering is presented on below-mentioned illustrations:

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 fixture resistant to an otdavaniye.« By Prikipaniye» elements of fixture it is connected with that they are constantly subject to external influences, are in contact to water, dirt, a soot and other promoting development of corrosion by substances. For the purpose of simplification of procedure of an otdavaniye of its such "become attached" fixture it is necessary to impregnate with plentiful amount of getting oil beforehand. Cleaning of open carving parts of fixture by a rigid wire brush also promotes simplification of an otdavaniye of prirzhavevshy nuts. Sometimes, in especially hard cases, for an otpuskaniye "become attached" bolts / nuts it is possible to use a drift. The drift rests against the region of a shliyets of a nut/head of a bolt, then sharp blows are struck to its opposite end with a hammer. Watch that the drift did not break, try not to damage in inexact blows a carving. Quite effective way is also warming up of fixture resistant to an otdavaniye and a surface of a component surrounding it a torch of a blowtorch or a gas torch though originators of this 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 receiving burns. Different extension pieces, collars and trumpet nozzles are intended for increase in a torque at an otpuskaniye of fixture on them. However, remember that it is not necessary to use such intensifying adaptations complete with the drive equipped with "graggers" — the risk of failure of the ratchet mechanism is too great. Sometimes the "become attached" fixture starts to give in after previously slightly will be tightened clockwise. All fixture, which otpuskaniye demanded application of extraordinary measures at assembly is subject to replacement!
|
After an otdavaniye attentively check a condition of fixture and in case of need make its replacement with elements of the same standard size. At assembly 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 of a rikhtovka of 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 situation (prepare reliable a jack and props).
|
At all do not perform any works under the car, fixed in the lifted situation only by means of a jack! |
