The invention relates to a spring-suspended, bearing force-optimized belt-band travelling gear (10) for ground vehicles, particularly for self-propelled agricultural machines and other off-road vehicles, comprising at least two outer deflection rollers (14, 15, 16, 17) over whose periphery an endless belt- band (22) rolls off, and at least one supporting roller (24) for supporting the belt-band section, which is in contact with the ground, between both deflection rollers (14, 15, 16, 17). A bogie truck (12, 13), in which the at least two deflection rollers (14, 15, 16, 17) are mounted in a manner that enables them to rotate, is supported against a body frame of the vehicle by means of a first fluidic suspension unit and/or damping unit. The at least one supporting roller (24) is supported on the bogie truck (12, 13) by means of a second fluidic suspension unit and/or damping unit. A fluidic coupling of the suspension units and/or damping units of the bogie truck (12, 13) is provided against the vehicle frame and the at least one supporting roller (24) mounted on the bogie truck (12, 13).
L'invention concerne un mécanisme de roulement à courroie (10), suspendu sur ressorts, optimisé en force d'appui, pour véhicules agricoles, notamment pour machines agricoles autotractées et pour d'autres véhicules tout-terrains, qui comprend au moins deux rouleaux de renvoi extérieurs (14, 15, 16, 17)), sur la périphérie desquels se déroule une courroie continue (22), ainsi qu'au moins une roue porteuse (24) pour soutenir la section de courroie côté fond, entre les deux rouleaux de renvoi (14, 15, 16, 17). Un chariot (12, 13), dans lequel les au moins deux rouleaux de renvoi (14, 15, 16, 17) sont montés rotatifs, est soutenu contre un châssis de montage du véhicule, au moyen d'une première unité de suspension et/ou d'amortissement fluidique. Le rouleau porteur (au moins au nombre de un) (24) est soutenu sur le chariot (12, 13) au moyen d'une seconde unité de suspension et/ou d'amortissement. Il est prévu un couplage fluidique des unités de suspension et/ou d'amortissement du chariot (12, 13) contre le châssis du véhicule et du rouleau porteur (24) (au moins au nombre de un) monté sur le chariot (12, 13).
