摘要： An earth-working vehicle, such as a backhoe loader, has an implement, such as a backhoe, mounted in a manner that the implement can be shifted transversely with respect to the vehicle. A hydraulic motor and roller cable or rack are secured to the vehicle main frame and implement supporting plate to position the implement transversely of the vehicle without the jerky movements of prior backhoe loaders.

摘要： A hybrid hydraulic system for a work vehicle is provided that includes a first fixed displacement hydraulic pump whose outlet is connected to a priority valve. The priority valve, in turn, directs the pump's flow to a first group of closed center backhoe valves on a primary circuit and a second group of open center loader valves on a secondary circuit. A second hydraulic pump is provided with independent load sensing capability to supplement fluid flow provided by the first pump.

摘要： A work vehicle includes a fluid circuit to operate at least one implement for performing work, the fluid circuit having at least a first operating mode and a second operating mode. The first operating mode is configured to operate within a first predetermined flow rate range within a first predetermined fluid pressure level range. The second operating mode is configured to operate within a second predetermined flow rate range and within a second predetermined fluid pressure level range. In response to the fluid circuit operating within the second operating mode, a maximum pressure value of the second predetermined fluid pressure level range is greater than a maximum pressure value of the first predetermined fluid pressure level range, and a maximum value of the second predetermined flow level range is less than a maximum value of the first predetermined flow level range.

摘要： A piston assembly for use in a hydraulic cylinder includes a piston head configured to slide axially within the hydraulic cylinder in response to changes in hydraulic pressure. The piston head has an axial through-hole. A piston rod has a proximal end axially abutting the piston head and a distal end extending outward through an end of the hydraulic cylinder. The proximal end of the piston rod has a threaded bore co-axial with the axial through-hole in the piston head. A bolt has a bolt head and an unthreaded shank portion adjacent the bolt head and a threaded shank portion away from the bolt head. The bolt secures the piston head to the proximal end of the piston rod when the bolt shank is inserted through the axial through-hole in the piston head and is threadingly engaged in the threaded bore in the piston rod. An annular washer is positioned and held captive on the unthreaded portion of the bolt shank between the bolt head and the piston head. The washer has a flat face abutting the piston head so as to concentrically transfer clamping force from the bolt head to the piston head when the bolt is threaded into engagement in the threaded bore in the piston rod. The piston head is secured between the bolt head and the piston rod.

摘要： A fluid control system including a variable displacement pump having a load system control and configured to operate in an open center mode. A pump control is operable between a first arrangement and a second arrangement. The pump control receives pressurized fluid from a first load sensor pressure in fluid communication with the pump and an actuator return pressure in fluid communication with an actuator configured to operate using pressurized fluid from the system, the pump control providing a selective pump control pressure to the pump load system control. When the system is operating in a standby mode, the pump operates in a first minimized displacement condition. When the system is in a stall mode, the pump operates in a second minimized displacement condition.

摘要： A work machine includes a fluid circuit for use with an attachment configured to operate using one of a uni-directional flow and a bi-directional flow through the attachment. An operator-enabled mode selection switch operably connects to a controller. An electrical circuit includes the operator-enabled mode selection switch and a second operator-enabled switch. A first control valve is in fluid communication with the attachment. In response to the mode selection switch being operator-actuated to a bi-directional mode setting, the first control valve via the controller is actuatable to one of the bi-directional positions, electrical power being unavailable to the second operator-enabled switch of the electrical circuit. In response to the mode selection switch being operator-actuated to a uni-directional mode setting, the first control valve via the controller secures the first control valve in the uni-directional position, and electrical power is provided to the second operator-enabled switch of the electrical circuit.
