An Analysis on Vehicle Behaviors during Braking 871232
When braking up a truck with a rigid axle type front suspension of parallel leaf springs, some steer angle deviations occur caused by relative movements between steering linkage pivot and the front axle. In case of heavy braking under nearly locking up conditions, it is expected that the vehicle may show some yawing motion during deceleration.
In this paper, vehicle behavior during braking were analyzed using a simplified simulation model. On the other hand, experiments were conducted to confirm the effects of these factors.
Comparing those results, it was proved that the analytical results show relatively good correspondence to these obtained from experiments and that vehicle behaviors during braking were greatly affected by the steer angle deviations and position of wheels which were locked.
