Abstract
A hydrostatic transmission system includes a fluid-driven motor and an integrated pump assembly connected to the fluid-driven motor to provide fluid to operate the fluid-driven motor. The integrated pump assembly includes a pump with at least one fluid driver comprising a prime mover and a fluid displacement assembly to be driven by the prime mover such that fluid is transferred from a first port of the pump to a second port of the pump. The pump assembly also includes two valve assembles to isolate the pump from the system. The hydrostatic transmission system also includes a controller that establishes at least one of a speed and a torque of the at least one prime mover to exclusively adjust at least one of a flow and a pressure in the hydrostatic transmission system to an operational set point.
Claims15
A hydrostatic transmission system comprising:
- a hydraulic motor having first and second ports;
- an integrated hydraulic pump assembly conjoined with the hydraulic motor, the integrated hydraulic pump assembly to provide hydraulic fluid to operate the hydraulic motor, the integrated hydraulic pump assembly including,
- a hydraulic pump having a casing defining an interior volume, the casing having a third port in fluid communication with the interior volume, and a fourth port in fluid communication with the interior volume, the hydraulic pump having at least one fluid driver disposed inside the interior volume, each fluid driver having at least one of a variable-speed or a variable torque motor,
- a first valve assembly in fluid communication with the first and third ports, and
- a second valve assembly in fluid communication with the second and fourth ports;
- and
- a controller that establishes at least one of a speed or a torque of the hydraulic pump to exclusively adjust at least one of a flow or a pressure in the hydraulic system to an operational set point.
