Abstract
Une cale de roue comprend une surface de charge convexe conçue pour le raccordement à un pneu de véhicule. La force résultante exercée par le pneu sur la cale de roue peut être exprimée comme vecteur normal de la surface convexe à langle de contact ?. À mesure que des forces de chargement dynamiques poussent le véhicule dans la cale de roue, le pneu remonte la surface convexe de la cale, ce qui fait augmenter langle de contact ?. Pour les angles de contact plus grands que 45 degrés, la composante verticale de la force résultante augmente et la composante horizontale diminue. Leffet net est que, sous un chargement dynamique, la cale a tendance à sancrer vers le bas plutôt que de glisser vers larrière ou se renverser. Il est aussi décrit un extracteur de cale fixé à la cale de roue. Tourner la poignée de lextracteur fait tourner le pied de lextracteur, qui fait pivoter et lève la cale de roue au-dessus du sol pour dégager la cale.
