    摘要： A large displacement hydrostatic variator is disclosed which includes an input shaft coupled to at least first and second hydrostatic pumps. Two hydrostatic pumps are utilized instead of one larger hydrostatic pump because it has been found the two smaller hydrostatic pumps can operate at a faster speed than a larger hydrostatic pump with a displacement equivalent to that of the two smaller hydrostatic pumps. Each hydrostatic pump may include a carrier that includes a plurality of recesses. The recesses may serve as cylinders for slidably accommodating a piston in each piston of each pump may be pivotally coupled to an adjustable swash plate. A hydrostatic motor may be coupled to an output shaft. The motor includes a carrier that also includes a plurality of recesses that may also serve as cylinders for each slidably accommodating a piston. Each piston of the motor may be coupled to a swash plate. The adjustable swash plate of each pump may be coupled to an actuator, which may be controlled by a single controller.

    摘要翻译： 公开了一种大排量静液压变速器，其包括联接到至少第一和第二静液压泵的输入轴。 使用两台静液压泵代替一台较大的静液压泵，因为已经发现两个较小的静液压泵可以以比两个较小的静液压泵的位移相等的较大的静液压泵更快的速度运行。 每个静液压泵可以包括包括多个凹部的载体。 这些凹槽可以用作用于可滑动地容纳活塞的气缸，每个活塞在每个泵中可枢转地联接到可调节的斜盘上。 静液压马达可以联接到输出轴。 电动机包括一个载体，该载体还包括多个凹槽，其也可以用作可滑动地容纳活塞的气缸。 马达的每个活塞可以联接到斜盘。 每个泵的可调节斜盘可以联接到致动器，致动器可由单个控制器控制。

    摘要： A hydraulic circuit associated with a hydraulic actuator is provided having a reservoir situated to hold a supply of fluid and a pump situated to supply pressurized fluid to the hydraulic actuator. The hydraulic circuit also has a pressure intensifying valve fluidly connected to the reservoir and the hydraulic actuator. The pressure intensifying valve is situated to direct fluid to the reservoir while in a first position and direct fluid to the hydraulic actuator while in a second position. The hydraulic circuit further has a flow divider including a housing with an inlet fluidly connected to the pump, a first outlet fluidly connected to the hydraulic actuator, and a second outlet fluidly connected to the pressure intensifying valve. The flow divider also includes a first fluid transporting portion fluidly connected to the inlet and the first outlet and a second fluid transporting portion fluidly connected to the inlet and the second outlet. The flow divider further includes a first variable displacement actuator associated with the first fluid transporting portion. The first variable displacement actuator is situated to regulate a volume change associated with the first fluid transporting portion.

    摘要： A method is provided for controlling a hydraulic system having at least an implement pump, a fan-steering-braking (FSB) pump, a valve assembly, a fan drive system and one or more accumulators. The method may determine an operational state of a power source associated with the hydraulic system, actuate one or more valves of the valve assembly such that the FSB pump charges the accumulators and operates at least the fan drive system if the power source is operating at less than maximum power, and actuate one or more valves of the valve assembly such that the accumulators operate at least the fan drive system and such that the FSB pump supplements the implement pump as needed if the power source is operating at maximum power.
