摘要： Provided is a hydrostatic system including a first hydraulic unit, second and third hydraulic units fluidly connected to the first hydraulic unit, and a hydraulic accumulator fluidly connected to the first hydraulic unit and the third hydraulic unit. The hydrostatic system may be operated in a hydrostatic driving mode where the hydraulic accumulator is isolated from the system and the first hydraulic unit drives the second and third hydraulic units, and in a hybrid driving mode where the hydraulic accumulator supplies fluid to the third hydraulic unit and the first hydraulic unit supplies or does not supply fluid to the second hydraulic unit. By isolating the hydraulic accumulator from the system, the hydrostatic system may be operated with reduced system lag in certain situations, and the hydraulic accumulator and brake regeneration may be utilized in certain situations to increase energy efficiency.

摘要： A power system for storing, recovering, and/or using energy from a vehicle powered by a prime mover, including a hydraulic pump/motor configured to be driven by the prime mover, a hydraulic accumulator for storing energy, a body hydraulic and/or an auxiliary hydraulic, and a valve manifold selectively fluidly connecting the hydraulic pump/motor to the hydraulic accumulator and the body hydraulic and/or the auxiliary hydraulic. When the prime mover is operating, the hydraulic pump/motor may selectively power the body hydraulic and/or auxiliary hydraulic, or may selectively charge the hydraulic accumulator, or both. When the prime mover is off, the hydraulic accumulator may selectively power the hydraulic pump/motor to start the prime mover. The stored energy in the hydraulic accumulator may be used to power other hydraulic components of the vehicle as well. Such a configuration provides a less complex and more fuel efficient hydraulic power system for starting the prime mover.

摘要： A swing drive system for an excavator is provided which utilizes a prime mover mechanically connected to a first hydraulic pump/motor and a second hydraulic pump/motor mechanically connected to a swing mechanism. The system includes a hydraulic circuit connecting a hydraulic fluid reservoir, a hydraulic accumulator, the first hydraulic pump/motor, and the second hydraulic pump/motor. The system is operable in one mode where the second hydraulic pump/motor acts as a pump to retard movement of the swing mechanism and pressurized hydraulic fluid from the second hydraulic pump/motor is pumped into the hydraulic accumulator. The system is operable in another mode where the pressurized fluid from the hydraulic accumulator is used to assist the prime mover in driving hydraulic consumers, including the swing drive.
