Steering adjustment is needed at low currency stability Car on high speed Movements (the steering wheel, no matter how much).

This defect is associated with a violation of the adjustment of the stubborn bearings of the screw, and in the rake-piston pair - the steering sector of the steering mechanism.

After adjusting the effort required for rotation input tree, it should not be markedly. During operation, constantly monitor the state of the hoses, especially high pressure. With cracks, blooms and cuts, the hoses must be replaced. You should also check the absence of leaks working fluid (Oils) from under hose clamps, steering wheel cover or amplifier pump. With the increase in pressure in the system due to jamming byproof valve may squeeze technological plugs In the pump housing, therefore, follow the system and quality of the flowable working fluid, on time to produce its plot, replacement and filter shift. Should not be detained for a long time steering wheel In extreme positions. This may damage and even encourage the amplifier pump. Weak noise when working the amplifier is not a sign of a malfunction.

Adjustment

Remove the steering mechanism without removing the bumps.	1. Push the mechanism in the vice fittings down and drain the remains of the oil into the container, turning the mechanism shaft to 17.
2. By pressing the shaft of the spool, we shake the sushka. If the axial lusted of the shaft is felt, adjusting the stubborn bearings.	3. To do this, through a beard or spike, straighten the tight of the adjusting nut, linked to the crankcase grooves.
4. Special key Turn the nut clockwise until the gap is eliminated. In this case, control the moment of rotation of the shaft, which should be not more than 0.2 kgf.	5. For this, the dynamometer inserted for the key to 17 measure the moment of turning the shaft-spool.

Commercial transport is completely optional to have a mass of equipment that promotes comfortable and safe driving. Although it was possible even for a deep scoop. Recall at least RAF 2203, which was considered almost a model of a minibus comfort. Despite the fact that he was completely assembled on the nodes and the aggregates of the Volga. This icon is Soviet route taxi And ambulance cars at the time to put a monument - RAF not only somehow did not deteriorate from congenital Volgov diseases, he managed to become an absolutely self-sufficient and comfortable vehicle.

What was, then passed, and gas 3302 Gazelle came to replace the raffik, to which they were pinned big hopes. As a result, for 20 years of release, it remained a gasoline tractor with a landscape and a Kocher KPP, gratifying with incurable diseases. Since choosing in this price segment Not at all, the car uses forced popularity and taut drivers.

Features of the steering gearbox GAZ 3302

Like the whole car, the gazelles do not suffer from the sophistication of the design, but many believe that this is for the better. Regardless of, with GUR car, or without an amplifier, repair and steering adjustment is extremely simple and do not require deep encyclopedic knowledge from the driver and special tool. The minimum of both - and you can go on.

Video review Gazelle 3302.

From the prehistoric gaseous worm-roller gearboxes, it is still different, and even has its own positive sides. The most pleasant feature from the point of view of the car architecture - the gearbox mechanism of Gazelles is quite compact and at the same time has a good efficiency. What is especially noticeable on machines without a steering amplifier - management even loaded by car does not require the use of rough physical power. Designers have achieved this by applying exchanging instead of slipping. It cannot be said that this introduction made revolutionary changes at the end of the 20th century to the world auto-industria, but the steering wheel became noticeably easier. This made it possible to increase the resource of the entire node, since it is not so intense, like a worm pair, and adjustments require rarely.

It did not cost without flaws, although the designers have nothing to do with it. The working pair of the screw / ball nut is a non-exposive element, and the first years of 10-15 car release to find a pair for replacement was quite difficult. Now this kind is enough, so replacement of the working pair can do 5-6 thousand rubles. Adjusting the steering gear assumes its full disassembly, which also does not cause delight of users. Moreover, for adjusting the gap, except for the key of a special profile, more even and skilled hands are required, since it is possible to overload the bearings in two accounts, if you do not use a torque wrench.

But the main surprise for the driver, resulted in adjustment or repair of the gearbox, is the dismantling of the bump. This is not hellish work, but in the cold, the disassembly of the bumps can cause some discomfort.

Repair of the steering gearbox Gazelle

From a good life, no one wants to remove the steering gear with their own hands, and the reasons for this should be more than good. Basically it is necessary if the steering wheel was noticeably sick, there were characteristic knocks in the gearbox crankcase or obvious leaks are observed. The gear is always sweating, but if the flow is too active, the replacement of the glands is shining. At the same time, it is necessary to control the state of the shaft and, if necessary, remove grinding traces of corrosion.

You can conduct adjustment and without a complete dismantling of the gearbox, but it will be calmer if it is still removed and inspecting carefully.

For curious or for those who are in a hurry, we give the technology of dismantling gear from under the hood:

• Fragment the fastening of the front wheels.
• Watching front axle on the stand and remove the wheels.
• Turn the steering wheel to the right to the right and from under the hood, you knock out the steering thrust suitable along the reinforcement length.
• The same makes the right.
• From under the hood, remove the gearbox along with the bump, which is more convenient to shoot on the workbench.

When we have a gearbox in our hands, we can repair it. The replacement of the details should not be presented to any difficulties, since the gearbox is very simple and understandable, and the adjustment should be paid to some attention and contact the factory adjustment data. They are also extremely simple.

For cargo Gazelle allowable Lental 25˚, for passenger - 20˚. According to the factory tolerances of the backup in the gearbox bearings, it cannot be. The adjustment of the gap in the screw bearings is carried out in the vice on the workbench. This is more comfortable. We remove the plastic protection and the foam seal, then unscrew the four bolts of the cover mount, take out one of the adjusting gaskets, then we collect everything in the reverse order. If there is a backlash, repeat the operation to dismantle the gasket. So until completely satisfying and digesting the backlash on the sosha.

When the backlash is chosen completely, we get to the adjusting eccentric rings. It is necessary to turn them alternately to avoid skewing and with a certain force - 10-18 kgf / cm. Adjustment is completed, now you can smoke the foam sealing gasket in the transmission oil, slot compounds consistent lubricant And install the steering gearbox in place.

Adjusting the steering mechanism GAZ-2705

Steering Speaker Regulation It is necessary to produce after adjusting the driver's seat relative to the control pedals. For this you need:

Rotate the handle 23 on itself and up, weakening the fixation of the steering column;
- set the steering wheel at a convenient position;
- fix the selected position of the steering column, turning the handle 23 down and from ourselves.

Adjusting bearings Conduct when an axial or radial gap in the screw bearing 2 (Fig. 2) to make sure these gaps are required:

Turn the steering wheel by 2.5 turns from the position of the straight movement to any side;
- to shift the screw of the steering mechanism for the fixed fork by hand; If at the same time the screw will have axial or radial movement (the play of the plug relative to the steering cover), then the screw bearings must be adjusted.
Adjustment is produced in the following sequence:
. Disconnect the tower 18 and the plug of the shaft 12 steering wheels;
. replete the steering bolts to the bracket and remove the steering mechanism from the car;

Merge oil through a hole closed by plug 4;
. remove two plugs 20 on the crankcase;
. Remove the two covers 17 and 19 and the sponge seal 16 of the sector shaft;
. Remove the lock ring 14;
. straighten up the beard of the well on the bearings of the shaft sector and remove them by the puller, eliminating the blows and swaps on the bearing;
. Remove the shaft sector 3;
. Remove fastening bolts top cover Carter, remove the lid and take out one of the adjusting gaskets 5;
. Set the crankcase cover to the place and check the moment of rotation of the screw in the bearings. The moment must be 0.4-0.8 nm. At the same time, the backlash of the screw should not be felt;

Install the shaft sector 3 and bearings, smearing the seating surfaces and sealing rings Oil for the steering mechanism. When installing, bearings should be directed by an eccentricity down (the shaft sector is maximally removed from the ball nut). Drying when assembly are not allowed. The enclosure of bearings on the shaft shaft or crankcase indicates a distortion or improper orientation of the eccentricity of bearings;
. adjust the engagement in the pair of the nut-sector;
. Fix the Bearings of the Shallow Sector from the aggregation, bent the bin on the bearings into the holes on the crankcase;
. make an assembly of the steering mechanism in the reverse order;
. Install the steering mechanism on the car;
. pour oil;
. Set the tower 18 and the fork of the shaft 12 (when installing a wedge of 10 nut 6 and washers should be from the treated end on the fork 8).

Adjusting the engagement of the pair nut - steering sector.

The gap in the engagement of the working pair is considered to be permissible if the backlash at the lower end of the bay when the wheel position for movement in a straight line with the adjusted screw bearings is no more than 0.3 mm. If the backlash exceeds this value, then it is necessary to adjust the engagement of the pair of the nut-sector, as the operation of the car with excessive backlash leads to the failure of the steering mechanism.
Sequence of pair engagement checkup operations:
- put the wheels into the position of the movement in a straight line and the cooler of the steering wheel combine the risk " FROM"At the end of the screw with the edge" IN»Upper cover 9 (risk" ABOUT"Must be at the bottom);
- disconnect the longitudinal steering of the tower;
- Shaking the tower with your hand, determine the backlash at its end (this should not be felt by the axial backlash of the screw). If the flavor of the tower is greater than 0.3 mm, adjust the engagement of the pair in the following order:
. remove the steering mechanism from the car;
. Remove two plugs 20 on the crankcase in the tree sector area;
. Disconnect the tower 18, remove the two covers 17 and 19 and the sponge seal 16 of the shaft sector;
. straighten up the well on the bearing of the shaft sector 3;
. adjust the engagement nut with the sector by simultaneous turn Outdoor rings 15 in the openings of the crankcase clockwise on the side of the slot on the shaft sector. When adjusting, eliminate the possibility of shallow blocks in the outer rings (incorrect orientation of the eccentricity of bearings).
The moment of rotation of the screw on the adjusted mechanism should be 1-1.8 n:
- fix the bearing of the shaft sector from the aggregation, moving the bin on the bearings into the holes on the crankcase;
- re-check the moment of rotation of the screw and the backlash at the end of the steering bump;
- set two plugs 20 on the crankcase, the sponge seal 16 of the shaft sector (smearing it and the shaft sector under it solidol), two covers 17 and 19 and a tower 18;
- install the steering mechanism on the car;
- Connect a longitudinal steering to the soul and to have a finger.

On new steering mechanisms, the moment of rotation of the screw is increased (to compensate for the partings of parts) to 1.8 ± 0.35 nm.

If you need to adjust the mechanism of fixing the column, it is necessary:

Remove the lower casing 8, unscrewing two screws and freeing it from the lower retainer;
- remove the upper cover 24, bringing the driver to the driver as much as possible;
- weakening the locknut tighten the bolt with a torque of 9.0-12.5 nm (0.9-1.25 kgf);
- fix the countercount with a moment of 14-18 nm (1.4-1.8 kg / m), eliminating the bolt turning;
- check the fixation of the column;

Install the upper and lower housing.

Features of the steering car Gazelle

On the car Gazelle can be installed steering Both without a hydraulic power, and with a power steering.

Steering without hydraulic

The car installed steering, consisting of a steering column with a wheel, steering mechanism and steering drive. Steering column Allows you to change the position of the steering wheel in the height and angle of inclination. Upper end The shaft of the steering column is connected to the steering wheel with conical slots, and the lower - through cardan hinges associated with a steering screw.

The steering mechanism consists of an aluminum crankcase, screw with ball nut and shaft sector.

Fig. one

The screw is installed in the crankcase on two radially resistant ball bearings. On the screw installed a ball nut with inside a screw groove. Between the nut and the screw placed a set of balls. When rotating the screw, the balls are rolled along the screw groove and the ball nut moves along the screw. At the same time, the nut turns the tree sector, installed in the Carter on two roller bearings. On the conical slots of the shaft sector, the steering bump is fixed. The screw with the ball nut and the set of balls is chosen to each other and, if necessary, be replaced only in the collection. Adjusting the engagement of the ball nut with the shaft of the sector is made by turning the eccentric bars of the BAL sector bearings. The steering mechanism is lubricated transmission oil (0.5 l), filled into the crankcase through a tube with conical carvings. The steering wheel drive consists of thawing, longitudinal and transverse steering, levers of rotary fists of wheels and steering hinges. Steering tush Longitudinal traction connected with the lever swivel fist left front wheel. Transverse tie Rod Binds the levers of both wheels, synchronizing their turn. Its length can be adjusted, which allows you to change the angle of wheel convergence. The angle of longitudinal I. transverse inclination The axis of rotation and the collapse of the front wheels are set by the design of the front suspension and are not regulated during operation. All hinges connecting the elements of the steering drive, unified, inseparable and do not require maintenance.

Steering with a hydraulic switch combined with a steering mechanism

In the steering mechanism with a built-in hydraulicer instead of a roller on the shaft shaft, a three-comed sector is cut, and the worm role performs the screw associated with the piston-rail installed on two stubborn bearings, whose preload is regulated by a nut. In the steering mechanism crankcase, a hydraulic cylinder was performed, in which the piston-rail is moved along the screw. The piston is made at the same time with the ball nut and has a teeth that come into engagement with the teeth of the tower tree sector. The piston divides the cylinder into two cavities. With a fixed steering wheel, the pressure in them is the same. Depending on the direction of rotation of the steering wheel, the corresponding cavity of the cylinder is connected through the hydraulic distributor with a high pressure injection line, and the other with the discharge. Pressure fluid (oil) In the steering amplifier hydraulic system, it creates a paddle type pump with belt drive from pulley crankshaftmounted on the front of the engine. IN expansion tank The steering hydraulic power system is placed by the filter element, delaying particles of more than 45 μm. The steering wheel drive consists of a steering trapezium, trenches of bumps and levers. In the eye of the pendulum lever and in the tips of the thrust are pressed by self-thinning collapsible hinges with hemispherical fingers. Rules of the steering trapezium have adjusting tubes, and corrugated spots are pressed on their tips rubber seals from metal clip. Hinges of busty traction and pendulum lever are protected by cap rubber seals.
