4.1.1. Wheels and tires

Corners of installation of forward wheels
At check of corners of installation of forward wheels by means of the special adaptation (wheel alignment tester) always establish the car on an equal horizontal surface so that forward wheels were in the provision of rectilinear movement. Before check be convinced that the forward suspension bracket, a steering and wheels are in a normal technical state, and pressure in tires corresponds to norm.

Convergence of wheels

Convergence of wheels
Fig. 4.1. Convergence of wheels


The convergence of wheels (a difference of the sizes B – And or the sum of corners and + b) is regulated by rotation of tips of steering drafts (fig. 4.1).
For change of a convergence of wheels rotate tips of the right and left steering drafts on identical corners in opposite directions. The size of a convergence will decrease at rotation of a tip of the left steering draft in the direction to a back part of the car (and a tip of the right steering draft – in the direction to a forward part of the car).
Convergence V-and: nominal rate – 0±2 mm.

Adjustment of a convergence of wheels
Fig. 4.2. Adjustment of a convergence of wheels



NOTE
Adjustment of a convergence of wheels is made by turn of tips left and the right steering drafts on identical corners (fig. 4.2).

At adjustment of a convergence of wheels weaken collars of protective covers of steering drafts for prevention of twisting of covers.
After adjustment reliably tighten lock-nuts of tips of steering drafts and reliably establish collars of protective covers.
Execute adjustment of a convergence of wheels so that the result corresponded to a range + 1мм.
Moment of an inhaling of a lock-nut of a tip of steering draft: 50–55 N · m.

Disorder of wheels
Disorder of forward wheels is provided with geometry of a forward suspension bracket (mutual position of a rotary fist and a forward rack of a suspension bracket) i.e. is adjusted at manufacturer and is not subject to adjustment in use.
Disorder of wheels: 0 ° + 301.

Longitudinal inclination of an axis of turn

Longitudinal inclination of an axis of turn
Fig. 4.3. Longitudinal inclination of an axis of turn


The longitudinal inclination of an axis of turn is adjusted at manufacturer and (fig. 4.3) is not subject to adjustment in use.
If the longitudinal inclination of an axis of turn does not correspond to nominal rate, replace the deformed or damaged details of a suspension bracket.
Longitudinal inclination of an axis of turn: 2°49 '+30'.

NOTE
The worn-out or damaged details of a forward suspension bracket should be replaced before check of corners of installation of wheels.


The special tool for measurements of corners of installation of wheels
Fig. 4.4. The special tool for measurements of corners of installation of wheels


The special adaptation (09529-21000) is applied to measurements of corners of installation of wheels (fig. 4.4).
The longitudinal inclination of an axis of turn and disorder of wheels are adjusted at manufacturer and are not subject to adjustment in use.
If the longitudinal inclination of an axis of turn and disorder of wheels do not correspond to nominal rate, replace the deformed or damaged details of a suspension bracket.
The difference in installation corners (a longitudinal inclination of an axis of turn and disorder of wheels) between the right and left wheel should be within 0 °±30’.

Corners of installation of back wheels

Tip of the left cross-section lever
Fig. 4.5. Tip of the left cross-section lever


Rotation of a tip of the left cross-section lever clockwise increases a convergence of wheels (fig. 4.5).
Rotation of a tip of the right cross-section lever clockwise reduces a convergence of wheels (see fig. 4.5).
Nominal rate: 3–7 mm.

NOTE
Adjustment of a convergence of back wheels is made by change of length (turn of tips) cross-section levers of a suspension bracket.

Wear of tires

Height of drawing of a protector of tires
Fig. 4.6. Height of drawing of a protector of tires


Measure height of drawing of a protector of tires (fig. 4.6).
Height of drawing of a protector of tires (minimum admissible value): 1,6 mm.
If height of drawing of a protector less minimum admissible value, replace the tire.

NOTE
At achievement of minimum admissible height of a protector on the tire there are strips of the indicator of wear.

Measurement of palpation of wheels
Will hang out wheels of one of axes of the car and establish under the car safety racks.

Points of measurement of palpation of a wheel
Fig. 4.7. Points of measurement of palpation of a wheel


Measure wheel palpation by means of the indicator of hour type, as is shown in drawing 4.7.
Replace a wheel if its palpation exceeds maximum permissible value.
Wheel palpation (maximum permissible value of radial palpation of a steel disk): 0,6 mm.
Aluminum disk:
The axial..... 1,0 mm
The radial...... 0,3 mm
The axial...... 0,3 mm

Inhaling of nuts of fastening of a wheel
The moment of an inhaling of nuts of fastening of a wheel for a wheel with a steel disk and wheels with an aluminum disk the identical.
Inhaling moment: 90–110 N · m.

Inhaling of nuts of fastening of a wheel
Fig. 4.8. Inhaling of nuts of fastening of a wheel



ATTENTION
After an inhaling of nuts by means of the pneumatic tool (shock гайковерта) check the final moment of an inhaling a dinamometrichesky key (fig. 4.8).


Order of an inhaling of nuts of fastening of a wheel
Fig. 4.9. Order of an inhaling of nuts of fastening of a wheel


Order of an inhaling of nuts of fastening of a wheel (fig. 4.9).
Check the moment of an inhaling of nuts of fastening of a wheel after their tightening the nominal moment in diagonal sequence.

Shift of wheels

Scheme of shift of wheels
Fig. 4.10. Scheme of shift of wheels


At shift of wheels use the scheme provided on drawing 4.10.

Check of course stability
If at movement the car withdraws aside, change wheels in places according to the procedure given below.

Reinstallation of wheels at check of course stability of the car
Fig. 4.11. Reinstallation of wheels at check of course stability of the car


Trade places forward right and forward left wheels, then execute dorzhny tests for check of course stability of the car (fig. 4.11).

The reinstallation scheme at car withdrawal to the opposite side
Fig. 4.12. The reinstallation scheme at car withdrawal to the opposite side


If the car withdraws to the opposite side, trade places lobbies and back wheels, then again execute dorzhny tests (fig. 4.12).

The scheme of secondary reinstallation at car withdrawal aside
Fig. 4.13. The scheme of secondary reinstallation at car withdrawal aside


If the car withdraws aside, again trade places forward right and forward left wheels, then execute dorzhny tests (fig. 4.13).

Replacement of wheels
Fig. 4.14. Replacement of wheels


If the car withdraws to the opposite side, replace forward wheels new (fig. 4.14).
