7.3.8. Check and adjustment of corners of installation of wheels
THE GENERAL DATA

Adjustment of disorder of forward wheels

1 – a bolt of fastening of an arm of a beam;

2 – an arm of a beam of a forward suspension bracket;

3 – a lobby beam полвески

Adjustment of a convergence of forward wheels

1 – a counternut;

2 – steering draught;

3 – a draught tip

Check of an angle of rotation of forward wheels

And – distance between the tyre and the lever of a forward suspension bracket

Adjustment of corners of installation of wheels is recommended to be carried out at servicing deport.

Corners of installation of wheels should be regulated, if following details acted in film:

 – The lever of a forward suspension bracket;
 – A rotary fist;
 – Steering draught or a tip of steering draught;
 – The steering mechanism;
 – A beam of a forward suspension bracket;
 – A rack of a forward suspension bracket;
 – An arm of a beam of a forward suspension bracket;
 – The stabilizer of cross-section stability;
 – The back bridge.

Adjustment carry out:

 – At a serviceable steering and a running gear;
 – At normal pressure of air in tyres;
 – At a difference in protector height at the left and on the right no more than 2 mm;
 – At the equipped weight of the car.

The prevention

If at check of corners of installation of wheels the received values differ from specified, it is necessary to check up a cross-section inclination of a body of the car first of all.


Check and adjustment of a convergence of forward wheels

PERFORMANCE ORDER
1. To check up and if necessary to adjust disorder of forward wheels.
2. To check up disorder of back wheels.
3. To check up a convergence of back wheels.
4. To check up and if necessary to adjust a convergence of forward wheels.

Adjustment of disorder of forward wheels

Disorder of wheels regulate displacement of arms of a beam of a forward suspension bracket (the tab. Corners of installation of forward wheels see).

PERFORMANCE ORDER
1. Loosen the an inhaling of bolts 1 (fig. Adjustment of disorder of forward wheels see).
2. Move an arm of 2 beams so that disorder of wheels from both parties was identical.
3. Check up an angle of slope of an axis of turn of a wheel.
4. Replace bolts 1 and tighten their moment 70 Нм, then tighten on 90 .

Check of disorder of back wheels

PERFORMANCE ORDER
Corner of disorder of back wheels do not regulate. If it differs from nominal (the tab. Corners of installation of back wheels see), replace a beam of the back bridge.

Check of a convergence of back wheels

PERFORMANCE ORDER
Convergence of back wheels do not regulate. If it differs from nominal (the tab. Corners of installation of back wheels see), replace a beam of the back bridge

Adjustment of a convergence of forward wheels

Convergence of forward wheels regulate change of length of steering draughts. At wheel adjustment should be established in position of rectilinear movement (the tab. Corners of installation of forward wheels see).

PERFORMANCE ORDER
1. Loosen the an inhaling of counternuts 1 (fig. Adjustment of a convergence of forward wheels see) from both parties.
2. Turning steering draughts 2 key for шестигранники, achieve a demanded convergence of wheels. Thus the length of the right and left draughts should be identical.
3. Tighten counternuts 1.
The prevention

After turn of steering draughts protective covers of the steering mechanism should not be overwound.


4. Once again check up a convergence of wheels and if necessary repeat adjustment.

Check and adjustment of an angle of rotation of forward wheels

Angles of rotation of forward wheels regulate change of length of steering draughts.

Check and adjustment carry out in following cases:

– The difference of the maximum angles of rotation of the right and left wheels exceeds 2 ;
– At the maximum turn the wheel concerns suspension bracket or body details;
– The radius of turn of the car on the left differs from turn radius to the right.

PERFORMANCE ORDER
1. Turn a steering wheel in extreme position at first in one, and then in other party and measure distance and (fig. Check of an angle of rotation of forward wheels see) for the right and left wheel. The received values should be identical.
2. Loosen the an inhaling of a counternut 1 (fig. Adjustment of a convergence of forward wheels see) and, wrapping or turning on steering draught, achieve a demanded angle of rotation of a wheel.
3. Turn on or turn steering draught on the other hand on the same number of turns. Then tighten counternuts 1.
4. Check up and if necessary adjust a convergence of wheels.

Check of a deviation of the back bridge from movement on a straight line

Deviation of the back bridge do not regulate.

PERFORMANCE ORDER
1. Measure a convergence of the right and left back wheels.
2. Calculate a deviation. If identical signs (positive have value of a convergence of the right and left wheels or negative), it is necessary from большего to subtract values smaller and to halve. For example: a convergence of the left wheel +15 `, the right wheel +5 `, then (15 - 5) / 2=5. Means, a deviation of the back bridge equally 5 `. If different signs have value of a convergence of the right and left wheels, it is necessary to combine and divide their absolute values попалам. For example: a convergence of the left wheel +15 `, the right wheel - 5 `, then (15 + 5) / 2 = 10. A deviation of the back bridge equally 10 `.
