The general information
Forward suspension bracket
Components of a forward suspension bracket (model 2WD)
Components of a forward suspension bracket (model 4WD)
All models of mark of cars described in a given Management are equipped by the rigid forward bridge. On models 2WD the continuous tubular sleeve is applied; on all-wheel drive (4WD) models two steel sleeves of semiaxes are welded from each of the parties to pig-iron картеру differential (the Head Coupling and трансмиссионная a line more in detail see). The forward bridge is suspended by means of pair shock-absorbers and two screw springs. Four operating levers of a suspension bracket provide freedom of moving of the bridge in a vertical direction; horizontal displacement are limited by means of a cross-section jet bar. The stabilizer of cross-section stability serves for prevention of a swing of a body. Each of rotary fists is positioned by means of pair spherical support, запрессованных accordingly in the top and bottom ends of the forked beams welded on end faces of the bridge.
Back suspension bracket
Components of a back suspension bracket (it is shown model 4WD, for not all-wheel drive models the scheme is similar)
The back bridge consists from pig-iron central картера in which the differential is placed and steams of the steel tubular sleeves welded to картеру from its both parties (in the Head Coupling and трансмиссионная a line more in detail see). The back bridge is suspended by means of pair shock-absorbers and two screw springs. Four operating levers of a suspension bracket provide freedom of moving of the bridge in a vertical direction; horizontal displacement are limited by means of a cross-section jet bar. The stabilizer of cross-section stability serves for prevention of a swing of a body.
In system of hydrostrengthening of a wheel the box of the steering mechanism which transfers the rotary effort put to a steering wheel through system of draughts of a steering drive (сошка, average and connecting steering draughts) to levers of rotary fists of operated wheels is applied retsirkuljarno-ball type. Демпфер, established between the bridge and average steering draught serves for softening of an undesirable deviation of operated wheels from the chosen direction at a suspension bracket course).
The shaft of a steering column fastens to the mechanism of a steering box by means of small карданного the hinge. The design of a steering column provides its folding at blow during failure.
At work with suspension bracket and steering components it is often possible to face the problems connected with отдаванием of fixture. The fixture is under the bottom of the car and is subject to constant influences of a moisture, a road film, a dirt, etc. that leads it «прикипанию» and to complications at отдавании. For decrease in risk of damages at отдавании such "become attached" fixture the set of various type of getting structures with which during some it is necessary to impregnate fixing knot before отдаванием is issued. Зачистка an open carving part of fixture a wire brush also reduces danger of damage of a carving at отдавании bolts and nuts. Often to destroy "soldering" of a bolt with a nut it is possible by means of sharp blows of a hammer (through кернер), however it is necessary to accept safety measures against соскакивания кернера from an external surface of fixture and its hit on a carving part. Warming up of fixing knot by a gas cutting torch is extremely effective also, however in practice application of such way is undesirable in connection with real danger of ignition. Any application of collars and lengthening pipes allows to raise essentially size of the twisting moment applied on a head of a key, however it is not necessary to apply lengthening pipes complete with ratchet drives is is fraught with failure of the ratchet mechanism. Sometimes to shift "the become attached" bolt or a nut attempt of its rotation helps with a twisting direction (clockwise). Fixture, отдавание which has caused special difficulties at assemblage of knots should be replaced.
As the majority of the procedures described in the given Chapter, assumes поддомкрачивания the car and performance of works under it, it is necessary to take care in advance of presence of strong props for car keeping in the lifted position. For поднимания the car preferably use of a jack тележечного type which also can be applied for подпирания separate components during performance of works.
After easing or removal of any fixture of components of a suspension bracket or its steering it is necessary to examine attentively and, in case of need, to replace (corresponding on a standard size and a design). At assemblage it is necessary to pay steadfast attention to observance of the efforts of a tightening of carving connections recommended in spice. At all do not undertake attempts to warm up or in another way to straighten the deformed components of a suspension bracket or a steering - always replace their new.
