 | | Two wheels with positive castor angle (the kingpin extension falls before the point of contact with the ground) using two different systems, one is to incline the kingpin, and the other is to move the kingpin position in relation to the wheel axis, the straight line travel stability exists in both cases, |
 | | However, in the case of negative castor angle, the wheel is pushed, as it is the line of application of the force applied to the axis passes behind the mid-point of the wheel, without taking the direction of travel into consideration, |
 | | Other factors influencing the castor angle, low-pressure tyres, in modern vehicles, contribute to reducing the caster angle given to the kingpin during construction, in fact, when under the influence of active or braking thrust, the tyres deform and tend to increase the longitudinal offset by shifting their point of contact with the ground, |
