Adjusting the angles of the front wheels needed
to ensure the normal operation of the front suspension.
Violation of the specified angles of the wheels deteriorates,
ease of management, decreases the stability of the vehicle when
movement, resulting in premature wear of tire tread.
The angles of the longitudinal inclination of the axis of rotation of the wheels must be
positive values (the upper end of the axis is tilted from the vertical
reverse) and should not have a difference of angles greater than 0 ° + -30 ". Large
difference between the angles of inclination of the axis of the left and right wheels can cause
spontaneous withdrawal in the car away from the straight-line
Violation of camber is a one-sided wear of the tread
tires. For larger positive angle of the collapse of the outer
side of the tire tread wears out faster than the inside.
With a negative angle of collapse quickly wear out the internal
part of the tire tread.
The deviation of the toe permissible value leads to
intensive wear of tire tread. Increased convergence
leads to a stepwise deterioration of the tread expressed in
occurrence of acute step edges on the tread surface,
directed to the longitudinal axis of the vehicle.
The discrepancy between the wheels leads to deterioration of the appearance of acute
step edges outward, and is more harmful
and dangerous, as in this case the worse stability of the car.
