Abstract[English]
This patent discloses a single bilateral rotary-steering-torque transmission arm based light weight steering system for four wheelers, which can be optimally configured to provide close approximation to Ackermann condition. Ackermann (anti-Ackermann) condition requires wheels to turn by unequal steer angles for inner and outer wheel. Therefore left hand side mechanism and right hand side mechanism turns the wheel asymmetrically and reverses their role while steering other side. This steering mechanism accomplishes bifurcation mechanism of steering action in to two different modes of steering at each of the two front wheels by employing special assembly of two sets of elliptic bevel gears. Monotonic increase in transmission ratio of conjugate pair of elliptic bevel gears with respect to meshing point with unity transmission ratio in appropriate region of elliptic bevel gears is utilized to achieve pro-Ackermann condition (or anti-Ackermann condition depending on the installation).[French]
La présente invention concerne un système de direction léger basé sur un bras de transmission de couple de direction rotatif bilatéral unique pour les véhicules à quatre roues, qui peut être configuré de façon optimale pour fournir une approximation proche de la condition d'Ackermann. La condition d'Ackermann (anti-Ackermann) exige que les roues tournent selon des angles de braquage inégaux pour la roue interne et la roue externe. Par conséquent, le mécanisme côté gauche et le mécanisme côté droit font tourner la roue de manière asymétrique et inversent leur rôle en dirigeant l'autre côté. Ce mécanisme de direction réalise un mécanisme de bifurcation de l'action de direction en deux modes de direction différents au niveau de chacune des deux roues avant en utilisant un assemblage spécial de deux jeux d'engrenages coniques elliptiques. L'augmentation monotone du rapport de transmission de la paire conjuguée d'engrenages coniques elliptiques par rapport au point d'engrènement avec un rapport de transmission unitaire dans la région appropriée des engrenages coniques elliptiques est utilisée pour obtenir une condition pro-Ackermann (ou une condition anti-Ackermann selon l'installation).
