Title (EN) AMPHIBIOUS VEHICLE MOUNTED ON CATERPILLAR TRACKS
(FR) VEHICULE AMPHIBIE MONTE SUR CHENILLES
Abstract:
(EN) Vehicle comprising a hull and motorised aquatic propulsion members and motorised land propulsion members, this vehicle being able to move between a navigation position and a land transport position in which it rests on sets of caterpillar tracks. Each set of caterpillar tracks (1) is equipped with an even number of rollers (7) so as to define a set of adjacent roller pairs (71, 72). The rollers (71, 72) of each pair are connected to the chassis (2) by suspension means comprising a set (12) of at least two superposed curved elastic leaves made of a fibre-reinforced thermosetting resin, namely an upper leaf (131) and a lower leaf (132), the set being fixed on the one hand to the axles (9) of the rollers (71, 72) at its respective ends and, on the other hand, to the chassis (2) in its central part, and the upper leaf (131) and the lower leaf (132) of each of the sets of leaves (12) are joined together and covered with a layer of elastomer (14).
(FR) Véhicule amphibie comprenant une coque ainsi que des or- ganes de propulsion aquatique motorisés et des organes de propulsion ter- restre motorisés, ce véhicule étant mobile entre une position de navigation et une position de transport terrestre dans laquelle il repose sur des trains de chenille. Chaque train de chenille (1) est équipé d'un nombre pair de galets (7) de façon à définir un ensemble de paires de galets voisins (71, 72). Les galets (71, 72) de chaque paire sont reliés au châssis (2) par des moyens de suspension comportant un jeu (12) d'au moins deux lames élastiques courbes en une résine thermodurcissable renforcée par des fibres superposées, à savoir une lame supérieure (131) et une lame infé- rieure (132), fixé d'une part aux axes (9) des galets (71, 72) à ses extrémités respectives et d'autre part, au châssis (2) à sa partie centrale, et la lame supérieure (131) et la lame inférieure (132) de chacun des jeux de lames (12) sont liées entre elles et recouvertes par une couche d'élastomère (14).
