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 (13i) and the lower leaf (132) of each of the sets of leaves (12) are joined together and covered with a layer of elastomer (14).

A suspension system for a vehicle includes a first chassis rail and a second chassis rail, each extending longitudinally in an axial direction of the vehicle. Also included is a first leaf spring element extending longitudinally in the axial direction of the vehicle, the first leaf spring element operatively coupled proximate ends thereof to the first chassis rail and at an intermediate location to an axle assembly of the vehicle. Further included is a second leaf spring element extending longitudinally in the axial direction of the vehicle, the second leaf spring element operatively coupled proximate ends thereof to the second chassis rail and at an intermediate location to the axle assembly of the vehicle. Yet further included is at least one leaf spring extending in a transverse direction of the vehicle, the at least one leaf spring having a spring rate that is actively variable.
