The influence of angles
The influence of different angles over the road behavior, stability and abnormal wear preventing
of the vehicles tires.
CAMBER
The exit from the tolerance field of the left or right wheel camber, may have as result:
-
tires external or internal edge wear (excessive positive or negative camber);
- steering is deviating towards the camber angle is more pronounced (asymmetry), a deviation
from the trajectory is taking place, which must be corrected by means of the steering wheel (the
pronounced wear on the tire in question is occurring);
CASTER
A larger difference of 1° between the right side caster and left side, may have as result:
- a deviation from the trajectory, which must be corrected by means of the steering wheel, the
abnormal tires wear (the pronounced wear on the tire in question is occurring), tough steering,
instability when turning.
PARALLELISM
This adjustment has little importance over the vehicle road behavior.
Anyhow, note the followings:
-
a prominent closing may lead to tires external edges wear.
- a prominent opening may lead to tires interior edges wear.
DIMENSIONS UNDER CARRIAGE BODY
These are especially influencing the different angles of the steering geometry.
A vehicle, which has run a large amount of km, it will have under the carriage body, dimensions
smaller than a new vehicle.
This is the reason why some vehicle manufacturers, are prescribing, when the checking is
done with empty vehicle, different under carriage body dimensions and their respective places
where these values must be taken. Other vehicle manufacturers are recommending the suspension
compression by means of special (specific) tools or loading repartition in different places.
These different procedures (as performing ways) have as final purpose, the cancellation of the
vehicle suspension lowering, which has driven an important number of Km, compared with its
initial condition.
