The invention relates to a spring-suspended, bearing force-optimized belt-band traveling 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).
