Title
(EN) SUPPORT FRAME ASSEMBLY TO ENHANCE HIGH-SPEED STABILITY FOR A NARROW TRACK VEHICLE DURING TURNS
(FR) ENSEMBLE CHÂSSIS DE SUPPORT POUR AMÉLIORER LA STABILITÉ À GRANDE VITESSE D'UN VÉHICULE À CHENILLES ÉTROITS PENDANT LES VIRAGES
Abstract
(EN)
This invention relates to narrow track vehicles. Previously, narrow track vehicles had a tendency to overturn during high speed turns. embodiments of the present invention use a support frame assembly that has a pair of struts which apply counteracting forces on a vertical beam of a pivot frame assembly in response to pivotal movement of the pivot frame assembly relative to a fixed frame assembly. This increases stability in high speed turns.
(FR)
L'invention concerne des véhicules à chenilles étroits. Auparavant, les véhicules à chenilles étroits avaient tendance à se renverser pendant des virages à grande vitesse. Des modes de réalisation de la présente invention utilisent un ensemble châssis de support qui comporte une paire d'entretoises qui appliquent des forces antagonistes sur une traverse verticale d'un ensemble châssis de pivot en réponse à un déplacement pivotant de l'ensemble châssis de pivot par rapport à un ensemble châssis fixe. Cela augmente la stabilité dans les virages à grande vitesse.
