Abstract:
A hydrostatic drive system for a machine is provided. The hydrostatic drive system includes a first hydraulic circuit, and a second hydraulic circuit. The first hydraulic circuit includes a first pump and a first hydraulic motor configured to selectively receive a flow of pressurized hydraulic fluid from the first pump at a first pressure. The second hydraulic circuit includes a second pump and a second hydraulic motor configured to selectively receive the flow of the pressurized hydraulic fluid from the second pump at a second pressure. The hydrostatic drive system further includes a controller configured to maintain a pressure balance between the first and the second hydraulic circuits based on a difference between the first pressure and the second pressure.
