Abstract

L'invention concerne un dispositif de transport permettant d'obtenir une opération d'arrêt ou un changement de vitesse plus stable d'un corps de transport. Le dispositif de transport est composé d'une pluralité de corps de transport. Chaque corps de transport comporte : un corps de transport principal ; une partie de déplacement destinée à permettre au corps de transport principal de se déplacer sur une partie rail et un corps de contact de pression supporté par le corps de transport principal et en contact de pression avec une partie transporteur pour raccorder le corps de transport principal à la partie transporteur. Les corps de transport de la pluralité de corps de transport sont raccordés les uns aux autres par un corps de raccordement capable de se dilater et de se contracter dans la direction de transport. Parmi la pluralité de corps de transport, un premier corps de transport se déplace sur un rail de transport de manière à précéder un second corps de transport. Le corps de raccordement est configuré pour requérir une charge prédéterminée pour une déformation par contraction et une déformation par extension, respectivement. Le corps de raccordement permet au premier corps de transport et au second corps de transport de se déplacer à des vitesses différentes en raison de la déformation par expansion et par contraction et réduit le changement de vitesse relative du premier corps de transport et du second corps de transport.
