11.1.14. Corners of installation of wheels
THE GENERAL DATA

The convergence of forward wheels is regulated by change of length of steering draught at the released collar.

For adjustment of disorder of wheels on a car repair shop the top support of a rack of a suspension bracket which fastens these nuts is rearranged. The top support provides necessary correction of a corner of an axis of a rack.

The convergence of back wheels is regulated by replacement of plugs of levers of a suspension bracket by the dissymetric. Marks on the plug specify in size of an increment of a corner of a convergence.

Corners of installation of forward wheels

1. A vertical

2. Disorder of wheels (front view)

3. A line parallel to an axis of symmetry of the car

4. An axis of turn of a wheel

5. A longitudinal angle of slope of an axis of turn

6. A convergence of wheels

7. To a forward part of the car


Disorder With = А–В;

Convergence = Е–F (it is expressed in mm);

G – a corner of a convergence of wheels (it is expressed in degrees)

Wheels and tyres

On considered cars radial tyres are established. Tyres should vary in the complete set on an axis. At installation on an axis of tyres of different manufacturers track, that protector drawing, the design and the size of tyres were identical.

Change disks at strong damages (a bend, dents).

The new wheel should be отбалансировано before installation on the car.

Corners of installation of wheels

The corner of disorder of wheels, angle of slope of an axis of turn and convergence of wheels are subject to check. Definition of corners of installation of wheels is shown on the scheme.

Corners of installation of wheels are checked and regulated in car-care centre. On forward wheels are regulated a convergence of wheels (on a part of cars) and disorder of wheels. The angle of slope of an axis of turn is not regulated.

Disorder of wheels is regulated only at replacement of knot of the top fastening of a rack in knot in which the special clown, providing necessary correction of disorder of wheels is provided. The convergence of back wheels is regulated by replacement of external plugs of levers of a back suspension bracket by similar knots with asymmetry of plugs.
