  • HYDRAULIC SYSTEM FOR A STEERING SYSTEM OF A VEHICLE
    Publication number: 20180346017
    Abstract: A hydraulic system is provided for a steering system of a vehicle. The hydraulic system includes a pump that supplies pressurized fluid during an operation of the steering system. The hydraulic system also includes an accumulator that is in independent and selective communication with each of the pump and the steering system. When the pump is in the operational state to support the operation of the steering system, some of the fluid may be routed into the accumulator and stored in the accumulator for later use. In the event of failure of the pump when the steering system is in operation, the accumulator provides the required amount of fluid to continue operation of the steering system until charge in the accumulator depletes to a value that is no longer sufficient to support operation of the steering system.

  • Hydrostatic drive system with variable charge pump
    Publication number: 20080238187
    Abstract: A hydraulic system is provided having a reservoir configured to hold a supply of fluid. The hydraulic system also has a variable displacement pump configured to supply charge fluid and pilot control fluid to the hydraulic system. In addition, the hydraulic system has a closed-loop portion configured to receive charge fluid from the variable displacement pump and drive a mechanism. The hydraulic system further has a pilot fluid supply portion configured to direct pilot control fluid from the variable displacement pump to closed-loop portion.
