<p>Hydraulic transmission circuit (100,200,300,400,500) with N hydraulic motors (120,130;220,230;M1,M2,M3,M4;520,530), wherein each motor comprises N sub-motors (122,124;132,134), all N 2 sub-motors having the same cylinder displacement. The circuit comprises one common feed duct (106,206,306,506), adapted for receiving fluid under pressure, and to which one feed sub-motor of each motor is connected; one common exhaust duct (108,208,308,508), adapted for ejecting exhaust fluid, and to which one exhaust sub-motor of each motor is connected ; N serial ducts (142,144), each serial duct connecting a feed, first sub-motor (122,132) to an exhaust, N-th sub-motor (124,134) via N-2 interposed sub-motors, these N connected sub-motors respectively belonging to the N motors. This circuit allows tight synchronization of the N hydraulic motors.</p> |
