Design of a steering column
All models are equipped with a forward suspension bracket of a design of MacPherson. The top ends of racks are fixed in body support in a back part of mudguards of wheel arches, bottom fasten to the top parts of assemblies of rotary fists. Rotary fists are connected by means of spherical support to the external ends of control levers of a suspension bracket. Spherical support are built in control levers and in case of wear change assembled with the last. The forward stabilizer of cross-section stability enters into a standard complete set of all models. The bar of the stabilizer fastens to a car frame by means of pair of collars and is connected to suspension bracket control levers by means of special racks.
In a back suspension bracket of models 1993 and 1994 of вып. the rack-mount design in which basis assemblies of shock-absorbers with screw springs complete with four cross-section and two longitudinal levers are put is also used. The top ends of rack-mount assemblies are fixed on a car body, bottom fasten to holders of stupichny assemblies. Holders are fixed horizontally by means of longitudinal levers. The bar of the back stabilizer of cross-section stability fastens to a car body two collars and is connected to suspension bracket racks means of connecting drafts.
On models since 1995 вып. the back suspension bracket is organized by means of not cutting bridge which has been hung out by means of assemblies of telescopic shock-absorbers with screw springs both raskreplenny by longitudinal levers and a cross-section jet bar. By means of the cross-section jet bar which is freely rotating on the built-in rod of management, the bridge is connected to the car chassis.
All models are completed with the reechny steering mechanism with the hydraulic amplifier. Assembly of the steering mechanism is located behind the power unit in the lower part of a back partition of an impellent compartment and fastens to the bottom cross-section beam. Reechny transfer by means of pair of cross-section steering drafts is connected to rotary fists of operated wheels of the car. The internal ends of steering drafts are equipped with rubber protective covers, the condition and which reliability of fastening should be checked periodically.
The system of hydrostrengthening of a wheel consists of the steering pump put in action by means of a belt drive and connecting lines. Liquid level in the tank of the steering pump should be checked also regularly (see. Head of Control and routine maintenance).
The steering wheel fastens on a steering column and by means of the steering shaft equipped with kardanny hinges is connected to reechny transfer. Wear of components of kardanny hinges, reechny transfer and tips of steering drafts, being summarized, defines size люфта a steering wheel which should not fall outside the limits an admissible range.
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!
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).
