A compact variable structure in a motor vehicle drive transmission with one or more driving wheels (12) which can be placed on a motor vehicle chassis (11). The structure comprises a central body (14), at least one closing side cover element (16, 17) and three axes comprising a driving axis (18), a wheel or wheels axis (19) and an intermediate transmission axis (10). The central body (14) is of the plate type and provides on at least one of its two sides a series of four housings (20, 21, 22, 23). A first fixed housing (20) is suitable for the driving axis (18), and the remaining housings (21, 22, 23) for axes carrying gear wheels to selectively receive two pairs of transmission gear wheels (26, 30; 31, 32; 26, 30'; 31', 32') according to at least two positions of wheel bases in relation to the positioning of the wheel axis (19). The cover element (16, 17) provides at least two housings (35, 36; 39, 40) for the selected positioning of the axes (10,19). <IMAGE> |
