<p>A drive comprising a first group of cylinders (1) of a radial hydraulic pump, rotating in relation to the drive frame (2) about a first axis (a1), and torsionally integral with the input shaft (6) of the drive and with a housing (15) inside which the first group of cylinders (1) rotates; a second group of cylinders (28) of a radial hydraulic motor, rotating in relation to the frame (2) about a second axis (a2); an output shaft (60), the axis (a3) of which is located between the aforementioned axes (a1, a2), and which is integral with a gear (62) meshing with a gear (64) integral with the housing (15) in which the first group of cylinders (1) rotates, and with another gear (63) integral with the second group of cylinders (28); means for varying displacement of the first (1) and second (28) group of cylinders; and distributing means for alternately connecting the cylinders in the first group (1) with those of the second group (28). <IMAGE></p> |
