An undercarriage (10) with variable track gauge comprising a main frame (12), a first and a second sub-frame or spars (18, 20) each for supporting respective driving tracks (22, 24) of the undercarriage. The main frame (12) presents in correspondence with each longitudinal flank (14, 16) at least a respective seat (26, 28, 30, 32), for the sliding housing of a corresponding beam element (34, 36, 38, 40) extending from the respective sub-frame (18, 20). Means (42, 44) are provided for moving said first and second sub-frame (18, 20) between at least a first position with reduced track gauge, and a second position with widened track gauge. The undercarriage comprises means for blocking the sliding of the respective beam elements (34, 36, 38, 40) within the corresponding seat (26, 28, 30, 32) comprising a first inclined surface (46, 48) positioned within the respective seat (26, 28) and a second inclined surface (50, 52) positioned in correspondence with the outer profile of the respective beam element (34, 36) and co-operating with said first inclined surface (46, 48) to fasten the beam element within the respective seat (26, 28).
