ELECTRO-HYDRAULIC DRIVE SYSTEM FOR A MACHINE, MACHINE WITH AN ELECTRO-HYDRAULIC DRIVE SYSTEM AND METHOD FOR CONTROLLING AN ELECTRO-HYDRAULIC DRIVE SYSTEM
An example hydraulic system includes a hydraulic cylinder actuator comprising a cylinder and a piston, wherein the piston comprises a piston head and a rod extending from the piston head, wherein the piston head divides an internal space of the cylinder into a first chamber and a second chamber, and wherein the hydraulic cylinder actuator is unbalanced; a first pump driven by a first electric motor to provide fluid flow to the first chamber or the second chamber of the hydraulic cylinder actuator to drive the piston; a boost flow line; a hydraulic motor actuator; and a second pump driven by a second electric motor, wherein the second pump is fluidly coupled to the boost flow line to provide boost fluid flow to the hydraulic cylinder actuator.
