2103552 9215804 PCTABS00016 A driving hub (6) connected to a first shaft (3) rotatably carries primary planet wheels (10) meshing with a first (11) and a second (12) sun wheels in coaxial relation. The first sun wheel (11) is fastened to a helical crown gear (16) meshing with auxiliary planet wheels (18) rotatably linked to the second sun wheel (12). Eccentrically projecting from the auxiliary planet wheels are respective interconnecting elements (22) guided in a trochoidal rolling track (23) formed in a guide member (24) fastened to a second shaft (5). Each auxiliary planet wheel (18) is driven by a piston (28) engaged in a pressurization chamber (29) formed in the second sun wheel (12). A fluid supplying circuit (30-35) sends oil under pressure into the pressurization chambers (29) in order to transmit axial thrusts to the auxiliary planet wheels (18), which thrusts, by effect of the helical toothings, produce balanced forces interacting with a motive power so as to transmit motion from the first (3) to the second (5) shaft.
